According to statistics, China is currently the world's largest footwear producing countries, exports and consumption country, the gooey shoe occupies most of the market, 90% is a solvent based adhesives, the largest environmental pollution is precisely the unreasonable selection of adhesive for shoes. Although the environmental protection water-based glue after many years of technical innovation and market promotion, have a certain market share, but not the formation of large-scale application in shoemaking enterprise. Environmentally friendly water-based glue will become mainstream shoe glue, become a beautiful dream of the footwear industry.

   All the time, frequently shoe enterprise internal production staff glue poisoning. In March this year, Guangzhou City Safety Supervision Bureau of the toxic glue 2011 event processing result, closing five or six toxic glue supply enterprises, arrested 9 illegal businesses trial. Secretary Liang Xingxia in the cause analysis of toxic glue events in 2011 said, "is not a standardized production, two is the use of substandard glue." Although the law enforcement departments have carried out administrative punishment for illegal operations, but the safe operation problem of shoe factory employees or worthy of the industry.

  "Toxic glue" has always been the footwear industry "stealth killer", why do the same thing cannot be eliminated, but over and over again occurs? Why is there a water-based adhesive safety and environmental protection, but can not completely replace solvent glue? Water shoe glue and the prospect of its development process, and how? The newspaper interviewed on glue manufacturers and shoe-making enterprises, trying to find out the future direction of development of shoe glue from.

"Toxic glue" fiercer than tigers  

    According to relevant data, glue poisoning occupation disease is one of the occupation disease in recent years the incidence rate is high. In 2011, Guangzhou, Shenzhen, mainly the spate of glue poisoning incident as an example, migrant workers in Guangzhou City, shoe factory, handbag factory more than have been sent to the hospital, they have similar symptoms, eyes dull, incontinence, trembling hands, memory fuzzy, was diagnosed with two dichloroethane poisoning, also known as glue poisoning.

Why do these most manufacturers use containing two ethyl chloride glue? The source of these glue in where?

   "Nanfang Dushi Bao" in 2011 through the survey found, these factories of glue is the source of the production of small workshops, industry experts say, small workshop production of glue like boiled gruel, as long as you can get the formula, buy the ingredients can be produced, no development.

    The production of glue and not technical content. However, some people spend money through acquaintances to glue factory for technical personnel, buy recipe and ingredients, and then their random process. According to several sell glue stall owners said, in addition to small workshops, there are formal glue factory, also in toxic glue.

Experts say, have glue poisoning, exposure to toxic glue with a large number of workers are inseparable. In the face of this event, many people in the industry to glue industry situation is quite worrying. Glue poisoning is not only an industry problem, it is turned into a social problem can not be ignored.

   "National standard" adhesive with shoes and bags the drafting unit -- Guangdong Foshan Nanhai Bali chemical limited company technical director Lin Huayu said, leather shoes, sports shoes 90% adhesive manufacturing process. Among all kinds of shoes with adhesive, sticky outsole glue is the most important, the highest adhesive performance. Also the shoe-making enterprises, production enterprises adhesive most adhesive varieties concerned. The sticky outsole adhesive both at home and abroad, basically to chloroprene rubber, polyurethane rubber. Is the key to whether neoprene or polyurethane adhesive, solvent adhesive is still the mainstream market.

Driven by interests of toxic glue to ban

   Adhesive industry, some people describe is the smarter. Shenzhen Gu director silicone materials Co. Ltd. General Manager Huang Chutian as the national standard adhesive formulation expert, see frequent glue poisoning, heart regret.

   Huang Chu fill said, as early as in the last century, large amounts of benzene production of adhesive is harm to people's health. In 2001, the adhesive has the national standard, and restrict the use of benzene, then 1, 2- two ethyl chloride. In 2008, adhesive GB revised, provisions of the toxic substances in adhesive value, of which 1 per cubic meter, 2- two chloroethane precision must not exceed 5/1000. But in practical use, exceed the standard containing 1, 2- two ethyl chloride adhesive, the harm is very great.

    A not to be named the leather factory boss told reporters, the factory is to use inferior glue, in order to save costs, because a bucket of glue can brush 120 pairs to 150 pairs of shoes, than with your glue a pair of shoes can save the cost of two or three yuan, if a factory one day produce 500 pairs of shoes, can save 1000 yuan, a month is down, the cost savings is enough to pay the rent and wages.

   "There is no execution, GB is a mere scrap of paper". Huang Chutian thinks, the annual production of glue of enterprises, not including small workshops, many did not strictly enforce the adhesive of GB, the main problem is driven by interests.

    Toxic glue not only damage to the factory workers, destructive to the environment are also great. Lin Huayu heavy-hearted said, shoes our annual production of about about 13000000000 pairs, use about 400000 tons to solvent based adhesives and adhesive above, 80% of the ingredients are organic solvents, namely each year only footwear is organic solvent of more than 300000 tons of emissions into the atmosphere, a photochemical reaction, the formation of acid rain, give us ring
