Environmental security issues facing the future of market risk, the experts believe that due to the presence of the security risks, the pollution of the environment, the energy consumption is too high, rubber-based adhesives are facing the risk of future market. This development very early, many varieties, performance is excellent, very versatile prospects in the end how? This last week, adhesives and adhesive tapes Industry Association held in Beijing the eighth rubber-based adhesive technology and information exchange meeting, the authority of experts gives the answer: Only take effective measures as soon as the direction of the water-based development of truly environmentally friendly, rubber-based adhesives and avoid exit the market, continue to brilliant achievements.
Rubber-based adhesives in many other areas of the national economy and daily life occupies a pivotal position. Among them, neoprene adhesive adhesive and SBS (thermoelastic body) is a typical representative. For these two leading products, adhesives and adhesive tapes Industry Association adviser the Professor Li Zaidong proposed development.
Neoprene adhesive performance, uses a wide, durability, affordable, brilliant leader in the rubber-based adhesive for decades, has so far not yet able to fully substitute. The product is solvent-based, water-based (latex) type and the body type three categories. Dominant position in our country is still solvent chloroprene adhesive, and difficult to reverse in the short term. However, the solvent-based neoprene containing large amounts of toxic, hazardous, flammable, explosive organic solvent, while strictly constrained by environmental and safety regulations.
Li Zidong said: "accelerated neoprene adhesive water-based, traditional products also brilliant reproduction. Industry is struggling to improve the water-based product performance has been fruitful, is getting more sophisticated."
Li Zidong neoprene all-purpose adhesive development secrets, for example, evidence of this view. Into the 21st century, the survival of the neoprene all-purpose adhesive once precarious, the root cause is that which contains a large number of toxic organic solvents can be blasting. Or GB18583 implementation of mandatory standards, rescue of these products, it is not only not getting worse, instead vista. In recent years, solvent-based neoprene adhesives production statistics is powerful evidence: in 2009, 156,000 tons, 165,000 tons in 2010 and 168,000 tons in 2011.
Neoprene all-purpose adhesive critical to sustainable development is to be green and environmentally friendly, safe, otherwise, even if the performance is also the '兔子尾巴长不了', no matter how good the company also enterprises poured scattered. "Li Zidong wittily said, water-based neoprene is the future direction of development, it does not contain organic solvents, safe and non-toxic and non-polluting, but the problem is mainly rely on imports of raw materials, the cost is too high, coupled with the curing time long, 2011, production and sales is only 1,500 tons. enterprises continue to materials research, product costs down, so that the marketing. "
Another rubber-based adhesive backbone - SBS Adhesives, Li Zidong unique is there are low viscosity, high solid content, early Adhesion very, very long sticky time the available non-toxic or low toxicity solvent manufactured from solvent-based to water-transformation has inherent advantages. But the low heat resistance, aging resistance poor, poor durability and indifference by market. In recent years, industry colleagues continue to improve the selection of raw materials highlight the novelty, more scientific and reasonable adjustment formula to take the process is more advanced, and more emphasis on environmental. The product sales amounted to 19.5 million tons in 2011, has exceeded 168,000 tons neoprene adhesive. Obviously, SBS adhesive performance optimization to the next level, strong development Beecham rising star. He said: "can believe in the SBS rubber best for the future."
Then, he stressed: "solvent-based adhesive SBS green is the key to the sustainable development of solvent-based will remain important in the future for a long period of time, location, and therefore should use non-toxic or low toxic solvent, highly toxic, carcinogenic Benzene and 1,2 - dichloroethane and other harmful solvents simply can not afford to use the best production of benzene-free and halogen-free SBS adhesive, as soon as R & D and production of parts with water instead of organic solvents even completely replace waterborne SBS adhesive. "
Up to now, the well-known large enterprises always adhere to environmental protection as the first concept. Shenzhen Gu Kang Li Chemical Co., Ltd. is the first company to promise never to use 1,2 - dichloroethane, benzene and other such toxic and carcinogenic solvents; Liaoning Lu Chemical (Group) Co., Ltd. and Guangdong ALTPACK Chemical Industrial Co., Ltd. is also determined not to use 1,2 - dichloroethane, benzene and mixed benzene contour toxic solvents; Fushun two brothers good chemical Co., the production and sales of green decorative purpose adhesive simply do not benzene, toluene, xylene, chlorinated solvents ... these enterprises, the development of environmentally friendly rubber adhesive beneficial exploration and attempt.
