According to media reports, Guangzhou poison glue incident, cases of the distribution of the enterprise, which are many for unlicensed without according to small mill, the space is narrow, environmental airtight, poor ventilation. The force chemical Professor Chen technical director think, if manufacturers in strict accordance with the relevant occupational health standards, strengthen ventilated, reduce the concentration of organic solvent, health workers can be guaranteed.
Second, environmental protection water-borne glue and hot melt adhesive should be adhesive development direction according to the introduction, environmental protection water-borne glue to using water as solvent, hot melt adhesive as solid glue need not solvent, in theory to solve the "toxic" this basic question.
Without solvent reactive polyester hot melt adhesive, with the aid of water or hot role of cross linking, and finally achieve better sticking strength. Hot melt adhesive as high performance environment protection adhesive, is the national "1025" focus on the development of technology.
Water-borne polyurethane coatings compared pu adhesives, without solvent smell, non-toxic, no pollution, incomplete glue easy cleaning, high solid content, safe and convenient to carry. In the 1990 s, European and American countries increasingly severe environmental protection laws and regulations, water-borne polyurethane adhesive got in industrial application.
In recent years, go against the news of the shoes export in frequent, such as the European Union in the implementation of the azo, phthalic acid methyl ester etc chemical testing, has become the European Union against China footwear products of powerful weapon. Europe and America etc for footwear products not only detect VOC content of footwear storage space and residue detection and become a shoes export objectively technical barriers.
Of course, the production of the comprehensive performance of water-borne glue the demand is higher, such as the content of solid requirements above 50%, hydrolysis resistance and so on.
According to the environmental protection water-borne glue is still mainstream reality, the force chemical Li Ruiyang deputy chief think, cost is not the question, and the key is shoe manufacturer of consciousness. Li Ruiyang analysis road, solvent glue 80% ~ 85% for solvent, effective solid content not more than 20%, and the content of solid water-borne glue of more than 50%, and three times the glue is solvent. The sale price of water-borne glue is 2 ~ 2.5 times of solvent glue in the market. Convert down, water-borne glue not only not expensive, even relatively cheap.
