Fumed Silica in adhesive application

Fumed Silica in adhesive applications in the adhesives and sealants, the fumed silica as a reinforcing agent and additives primarily played rheology control, anti-settlement, to prevent the flow of hanging and the reinforcing effect. Fumed silica of small particle size, surface area, surface Si-OH (Si-OH) and its aggregates more than three-dimensional branching structure, by making hydrogen bonds or van der Waals forces between the silica and polymer molecules, chlorine dioxide silicon molecules produce a strong effect, to reinforcement effect. Fumed Silica in adhesive and sealant systems uniformly dispersed, they can aggregate to form a silica network, aggregates through the surface of silicon-OH (Si-OH) and the polymer molecules to form hydrogen bonds, so that the flow system nature of restrictions, the viscosity increased, and thus play a role in thickening the same time, under the action of shear force, hydrogen bonding and silica networks were damaged, leading to decreased viscosity, which happened thixotropic effect, ease of construction, once the shear stress removed, silica network and the foryoga mation of hydrogen bonds again. So as to effectively prevent the product during storage and use of the settlement process in the flow of hanging. In the solvent-based PU adhesive for shoes to add a suitable fumed silica not only help improve the PU adhesive bond strength, but also can significantly extend the storage stability of the glue. (Reflected in viscosity and stability), the larger the current domestic shoe manufacturers have used PU glue, PU glue is generally used in models HL-150, HL-200, hydrophobic model: HB-215 to add the ratio is generally 0.5 ~ 1.5%. The national industry - the nation's largest fumed silica (fumed silica) factory in Guangzhou Ji Bi Sheng (GBS) Technology Co., Ltd. is now the largest production of fumed silica (white carbon black) enterprise. Produces fumed silica with hydrophilic and hydrophobic, hydrophilic product: HL-150, HL-200, HL-300, HL-380, hydrophobic products: HB-215, HB-220 (dimethyl-2 chlorosilane treatment) and (6-methyl Disilazane processing) HB620 and HB630, etc. more than 10 models products.

Shoes with polyurethane adhesive polyester product

as polyurethane (PU) the synthesis of important intermediate compounds containing hydroxyl structure and the quality of not only profoundly affect the production process, but also determines the product performance. Shoes with polyurethane adhesive in the adhesive strength, tack, and temperature, etc. have high requirements, should adopt the high crystallinity of poly-butylene glycol adipic acid (abbreviated as PET) as its molecular chain of the soft segment.
polyester production process of the current main high-temperature vacuum dehydration and nitrogen dehydration. High-temperature vacuum dehydration and nitrogen-dehydration reaction temperature were 245 ℃ over a long period of high temperature, vacuum reaction, not only to equipment with high requirements, but also due to ring etherification, oxidation and other side effects may lead to products in the molecular weight distribution, color, etc. aspects of adverse effects. We are conducting solution synthesis of polyurethane rubber shoes course of the study, through small scale and gradually enlarge to 1000l reactor repeated practice of large-scale production and found that adopting a more mild reaction conditions, the production of polyester, not only the process simple and easy to control, and product quality can fully meet the solution method for producing polyurethane rubber shoes requirements.
1 Experimental part
1.1 devices
1000l stainless steel reaction vessel (oil bath electric heating, self-anchor-type stirrer, 87rpm), 50l oil-water separators, tube condenser, vacuum pump.
1.2 material
adipic acid, 1,4 - butanediol, toluene are made of industrial, chemical pure hydrated stannous chloride reagent, A home-made reagents.
1.3 Process
438kg adipic acid, 306 ~ 310kg1, 4 - butanediol and moderate (0.1%) A reagent added to the reactor, the weak pass N2, control the yoga material temperature is below 140 ℃ reaction 5h , this time a theoretical amount of water for more than 55%. As soon as the heat bath temperature rose to 200 ℃, and has remained the same in the future. When the yoga material to a temperature of 180 ~ 190 ℃ after adding 25kg of toluene reflux watershed. 2h after the sample test acid value acid value less than 14mgKOH / g, add 65g hydrated stannous chloride, 4h after the acid value fell to 4mgKOH / g below, decompression, at 0.01 ~ 0.02MPa pressure response to 0.5 ~ 1h. Cooling, discharging, may 621kg white waxy product, the yield of 83.2% (theoretical value: 85.5%), acid value 1mgKOH / g, hydroxyl value of 45 ~ 60mgKOH / g.
1.4 Acid test methods
take 1 ~ 2g polyester, dissolved in 20ml1: 1 benzene - ethanol solution to 0.1NKOH standard solution drip to the phenolphthalein indicator was slightly red.
2 Results and discussion
2.1 low response and high-temperature reaction
due to esterification equilibrium constant K value of only 4 ~ 10, the smooth progress of the reaction temperature is very necessary. Data show that the same reaction time, in ensuring 55% of the water under the premise of low-temperature phase of the reaction temperature is low, then the latter part of high-temperature, short reaction time; the same reaction temperature, low-temperature longer reaction time is better. This is mainly due to 1,4 - butanediol at 140 ℃ and above there exists an obvious phenomenon ether ring, the resulting tetrahydrofuran (THF) boiling point much lower than the boiling point of water, if the low-temperature phase can not use the fast response, less side effects favorable conditions, so that material fully, even oligomeric, then the amount of free-butanediol more high-temperature phase, as well as etherification evaporation caused by the loss of the more-butanediol results not only in the high molecular weight polyester polyols, affect the distribution of a wide range of side effects of its use is more important is the reaction of the latter part of acid value hard to drop, but a significant increase in high-temperature phase of reaction time. This not only reduces production efficiency, may also be due to decarboxylation, pyrolysis, oxidation and other side effects result in increased yellowing, in severe cases may lead to product obsolescence.
2.2 atmospheric pressure reaction and the vacuum
in the polymerization reaction, especially in response to the latter part of the viscosity greatly with decompression of small molecules emitted by-products and excess raw materials is necessary. At 200 ℃, the pressure 0.01 ~ 0.02MPa, acid value in the 4mgKOH / g, only 0.5 ~ 1.5h taking the time to time. Such as temperature, vacuum degree of increase or extension of decompression time, the initial acid value may be appropriate to higher. Because of the equipment in a sealed lamp area is difficult, hard to capriciously raise the degree of vacuum, while the higher the temperature or extending the reaction time also brings a easy to cause yellowing, so the initial acid value should not be too high. After the acid number generally less than 4.0 at room temperature is difficult to lower and lower, even down to 2.0 following decompression also have to find time for more than 0.5h. With the literature 6 ~ 8h, 0.01MPa, 220 ~ 240 ℃ taking the time to process conditions, compared the advantages of the process is self-evident.
2.3 acid to alcohol than to process the impact of
acid-alcohol ratio of 1:1.10 generally ~ 1.13, due to the market to buy raw materials in the purity of the practical situation, taking into account the requirements of the hydroxyl value to take acid to alcohol ratio To 1:1.13 ~ 1.15 is necessary. Increase in the proportion of alcohol and Technology also has a certain relationship, the higher the proportion of alcohol can greatly shorten the latter part of response time, especially in the pre-reaction temperature is low, especially when a longer reaction time. Slightly excessive amount of alcohol can be when you find time to recovery, within a certain range will not have a significant impact on hydroxyl value products.
2.4 Catalysis and water-carrying agent
With the increase in yoga material viscosity, the reaction progressively more difficult the latter part of the water, the reaction has slowed significantly. Acid value dropped as soon as possible so that the catalyst stannous chloride hydration can play an effective role 15mgKOH / g below, we have a weak back later with a small amount of toluene in water, works well.
3 Conclusion
the above discussion shows that the synthesis of polyester polyols, no higher than 220 ℃ under high temperature above, but also need long hours under high vacuum. As long as a sufficiently low temperature phase of increase and add water-carrying agent, you can conveniently and efficiently synthesized high-quality, suitable for synthesis of polyurethane solution used in polyester plastic shoes.

How to solve the LED thermal (transfer)

U.S. Department of Energy (DOE) on the led lighting to make the following assessment: There is no other like the LED lighting technology can have such a big energy-saving potential and improve the quality of our built environment. As the led lighting's life is a function of junction temperature, so thermal management is essential for the performance of led lighting. California San Jose is located in the Philips Lumileds Lighting Application Technology Manager, Rudi Hechfellner, said: "So far heat management is a led lighting system design of the most important aspect. led lighting system manufacturers by seeking to optimize the radiator, efficient printed circuit boards, high thermal conductivity thermal design of shell and other advanced technology to deal with this challenge. As the thermal simulation prior to the establishment in the physical model, from the perspective of thermal evaluation of different design and optimization of system-level design, it highlights the growing role of thermal simulation. "
LED lighting appears
is an emerging solid state lighting technology that will fundamentally change in the future in the form of lighting. LED design at the beginning of power less than 50 mW. In the past decade, LED power has risen to 40 ~ 80lm/Watt. In addition to energy-efficient addition, LED service life and long. Depending on the manufacturer and type of the life of a white LED can be in the range of 6,000 ~ 50,000 hours, the more than 30,000 hours of fluorescence (light) tube and 2000-hour incandescent bulbs. In addition, LED may not use filters to produce monochroyoga matic light.
market analysis firm Yole Developpement, said: LED solid state lighting market revenue in 2007 will rise to 1 billion U.S. dollars in 2012 to 103 billion U.S. dollars. Yole is expected in 2012 high brightness and ultra-high brightness LED combined revenues will reach 4.45 billion U.S. dollars, which is 700 million 8 million in 2007 to 5.5 times. These solid-state light-emitting devices has become a different light source selection applications, these applications include traffic lights, cars and trucks, the internal and external lights, the screen display can be seen, small LCD back lighting and decorative lighting. The latest Isuppli report (Reference 1) shows that in some new places have gradually adopted the LED.

Shoe Modification of polyurethane adhesive

0 INTRODUCTION
synthetic polyurethane adhesives and polyurethane adhesives industry and new materials industries important product categories, are widely used in various areas of the national economy. It has the amine, isocyanate groups, carbonyl and metal, rubber, plastic surface of the groups have a strong chemical bonds, and stronger co-operation with the van der Waals force, it has a better performance than other adhesives. the last two years, the domestic polyurethane adhesive production scale and technological development rapidly, but these enterprises mainly in Germany, Spain, the United States and other imported resin dissolved, formula modified. the largest amount of shoes for more than 95% of polyurethane resin to rely on imports, the domestic several smaller independent development of devices, equipment, technology is relatively backward, product performance, still fail to Foreign standards; Experts predict that China will significantly increase the demand for polyurethane adhesive, to 1998, 103,000 tons as the base, with an average annual growth rate of about 10%; 2005 adhesive for shoes is about 183,000 tons. After years of exploration and study and found that the use of flexible synthetic polyhydroxy chains shoe adhesive, as compared with the same polyurethane adhesive with better adhesion.

1.3 Preparation of polyisocyanate
the formula amount of TDI to join with dryer, blender, thermometer 3 flask, heated to 40 ℃, a gradual trickle-down polyol solution. about 2h drops finished, adding a catalyst Dibutyltin dilaurate, maintained at this temperature for 1.5h out pvc material, get 50% of the multi-isocyanate adhesive solution.
1.4 Performance Measurement
1.4.1 Adhesive
sample plate in 2mm thick mold, the coated with release agent, the vacuum deaeration and solvent had been removed more than the above-mentioned isocyanate adhesive casting mold in the flat, the room temperature for 48h, after stripping, and then placed on 7 days standby.
1.4.2 Tensile Properties of
will be a good film sample preparation, in the XL - 50A Electronic Tensile machine according to GB/T528-1998 "vulcanized rubber or thermoplastic rubber tensile stress-strain performance measurement" approach to testing the tensile strength and elongation at break.
1.4.3 Peel Strength
will be leather and rubber scissors into a 25mm wide-spline, using sandpaper polished hair, use a cotton ball dipped in acetone scrub addition to fat, to be volatile after the gluing of acetone, 3 ~ 4min after leather and rubber adhesive pressure, room temperature 24h; with tension test machine in order to (200 ± 10) mm / min loading rate of 180 ° means peel specimen, effectively stripping the length should be 70mm above, 10mm strip to the bonding part of the left until the calculation peel strength.
1.4.4 la shear strength:
with the PC board as a substrate a good sample preparation, in the XL-50A electronic pull machine refer to GB7124-86 "Determination of adhesive tensile shear strength" test tensile-shear strength.
2 results Discussion
polyester polyol and a diverse selection of polyol acid ratio, with multi-acid polyol choice, polyester polyols and TDI ratio experiment results are as follows:
2.1 Polyester Polyols effects on the adhesive properties of different
different polyester polyols of the adhesive properties of Table 1.
as diethylene glycol with ether, adipic acid long carbon chain of carbon atoms sp3 hybridized and therefore I from diethylene glycol with adipic acid polyester polyol prepared from a long chain of atoms are mostly free to rotate and therefore I have good flexibility. from the Table 1 known to use diethylene glycol with adipic acid and to a reasonable 1.20:1.00 ratio of income of the bonding agent for the best.
2.2 diols and diacids of different combinations and the relationship between the adhesive properties of binary acid and diols
ratio affects not only the poly - The molecular weight of polyol ester size, but also affects the main properties such as adhesive peel strength, tensile strength and so on. If the ratio of two low molecular weight may be too high, the viscosity is too large and the hydroxyl content is not directly cause adhesive containing-NCO reactive groups of the reduced impact of the use of the performance. excessively high molecular weight is too low, tensile and peel strength will decrease. diethylene glycol, and glycol ratio has influence on the adhesive properties are shown in table 2.
know that Diols from Table 2 with the ideal ratio of dibasic acid should be 1.2:1.0 2.3 polyester polyol and TDI of the OH / NCO ratio of
Since the adhesive is a reactive group -- NCO, in theory appear to be more of the group, combined with more points, naturally the greater the cohesive force. but that would require a significant increase in the amount of isocyanate, increase costs. At the same time no adhesive properties has risen markedly, but there is brittle became larger. based on the different OH / NCO ratio testing, the proceeds of bond performance index shown in Table 3.
know from Table 3, from the performance, cost factors into consideration to OH / NCO ratio 1.0:0.9 is appropriate.
2.4 of this product with a variety of performance polyurethane adhesive for shoes comparison
know from Table 4, this study applied the products as raw pvc materials such as diethylene glycol, and an appropriate ratio of the reactions, so its overall performance comparable with the imported products.
3 Conclusion
due to the production of ethylene glycol with diethylene glycol as a by-product of cheap, and its ether bond has good flexibility, in order to diethylene glycol instead of has been derived from the diol polyurethane adhesive, so that the cost of greatly reduced, due to a large number of amine, isocyanate groups, carbonyl, and rubber and leather has an excellent adhesive properties, its excellent flexibility, stretching and anti-stripping properties of non-Asian on certain imported products.
know from the above experiment, should choose diethylene glycol with adipic acid and to prepare for the ratio 1.2:1.0 shoe adhesive, polyester polyol. The polyester polyol thus obtained diisocyanate TDI with the ratio for OH / NCO = 1.0:0.9 for the better. Though the amount of increase in the performance of TDI has increased, but free of the TDI will be substantially increased, so that the damage caused by products increased substantially. and to 1.0:0.9 of the OH / NCO ratio, although the performance has not reached its highest point, but its very small quantities of free TDI, and TDI high prices, which will certainly lead to an increase in the amount of the cost has grown dramatically.
adhesive properties of this product tensile strength up to 56mPa, peel strength up to 5.6kN / m.

China is producing countries, according to statistics, in 2008, China's production has more than 10 billion pairs of shoes, of which exports more than 80 million pairs, the annual consumption of shoes with plastic more than 200 billion yuan. Such a huge market space, has attracted a number of illegal vendors desperate for shoe adhesive manufactured, sold, selling fake products crimes.
According to experts, counterfeit and poor-quality shoes, the benzene content in adhesives and other chemical components, if exceeded, will cause workers to poisoning, which not only seriously affected the reputation of the regular shoe manufacturers products, but also a serious threat to worker health and safety of life , for the credibility of the footwear industry will be adversely affected.
"counterfeit products result in at least a year to our company millions of dollars in lost sales, but also had a negative impact the company's brand, counterfeiting has become an important task of enterprises. "Domestic well-known shoe manufacturer Adhesive - tyrants force pouch belt chemical a person in charge of the very dissatisfied with the phenomenon of rampant counterfeiting.
It is understood that tyrants power company is well-known shoe adhesive manufacturers. Since 2007, Pa power companies began to receive reports about counterfeit products and complaints that end, the company organized a team equipment match-fixing.
2008 Nian 12 months, Pa power company found that the company's products "BALI RESIN" (Ba Li Licensing) shoes adhesive Huidong in Guangdong area is a serious fake sales. In view of the value of a huge scramble for power companies directly to the reported to the Police immediately launched economic crime detection.
in late March of this year, the police after careful investigation, in the Huidong captured two out Bowes involved. The trial, involved confessed fake adhesives produced for the Ming Bao, and counterfeiting a long time, selling a wide area, a huge amount of preliminary verification, only the number of fake goods in Guangdong Huidong region reached the million barrels. In Zhejiang, Fujian, Hubei and other areas, the number of fake goods are being investigated. According to business-related operations with the police officer said the company in recent years, Bao-Ming Li of counterfeit products, the value of hegemony as high as several million dollars.
3 end of the statements according to those involved, Putian, Fujian, Guangdong police rushed to the instigation of criminal suspects Peng Bao false arrests, and conduct further investigation and evidence collection.
At present, pouch case has entered a pre-trial phase.
"Although met with great resistance, but the company's determination to crackdown did not waver. "Ba Li chemical a person involved in pvc match-fixing, said:" match-fixing is not only to the legitipvc mate business interests against abuse, but also for the orderly development of the whole industry is of great significance, as the industry leader, we are duty-bound.
