Research and development of environmentally friendly neoprene adhesive

Chloroprene adhesive technology is widely used high performance rubber-based adhesives, types and structural formula of its main ingredients chloroprene rubber polychloroprene because of its high bond strength and water resistance, oil resistance to acid corrosion series excellent resistance, is widely used in shoe leather and rubber metal bonded construction and other fields.


    Our country is recognized as a large shoe manufacturer and exporter in the world, the total output of B pairs, most footwear with neoprene adhesives and graft neoprene, neoprene adhesives used in accounting for its total neoprene adhesives Adhesives can be divided into solution type emulsion and solvent-free liquid type, among which the solvent-based.


    In China the use of solvent-based glue is basically a type of structure types and anti-graft polybutadiene structural formula neoprene neoprene and polyurethane rubber polychloroprene one table - a bent along the 4-H in case polybutadiene, a polybutadiene system research and development of environmentally friendly production neoprene agent sticky Thinking Bringing Forth Wangji Hu Ming Wang Jun Hui o Shanghai Engineering Technology big a rare 4-polybutadiene rubber neoprene an earlier application in shoe adhesives industry, and achieved satisfactory bonding effect, a wide range of adhesive objects, so called universal adhesive, but due to the traditional neoprene adhesives based on aromatic solvent such as toluene, benzene, contact, easy arched body chronic poisoning, resulting in decreased white blood cells, and induce other diseases, seriously affecting the health of workers.


    Furthermore these harmful emissions into the plant, but aggravated the surrounding environment pollution and increased production costs and increase the fire hazard has some shoe factories due to the use of solvent-based adhesives and did not strengthen fire prevention measures, including fire incident and hair bow extensive use of triphenyl adhesives, at great cost to the enterprise, but also lead to economic and social aspects of the negative effects of many.


    Although now have no toluene neoprene adhesives, but only a small taste of low toxicity, can not yet be called environmentally friendly adhesives.


    It should have two basic characteristics of both harmless and do not cause pollution to the environment, a combination of both, it be regarded as a truly environmentally friendly adhesives.


    Therefore, the development of new environmentally friendly neoprene adhesives to replace traditional solvent-based neoprene adhesive mix, has become imperative.


    Production status of small adhesive nitrogen present, China's synthetic adhesive production enterprises, though of more than, but on the level of the manufacturers, but the West family, species than species, annual production capacity of up to Kui equipment coma village square, of which a considerable part of the enterprises, especially Some small business workshops in the production of chloroprene adhesive.


    Because of China's production of neoprene adhesives are generally used substances benzene or benzene as a solvent, so the use of toxic solvents gas release will produce workers' health and the environment caused great harm.
