Abstract

The invention discloses an environment-friendly chloroprene adhesive, which is characterized by consisting of the following ingredients in parts by weight: 100 parts of chloroprene rubber (CR), 40-90parts of resin, 0-2 parts of a catalyst, 0-2 parts of an anti-aging agent, 4-10 parts of magnesium oxide, 2-8 parts of zinc oxide, 0-1 part of an accelerant, 0-10 parts of filler and 350-55 parts of amixed solvent. The invention further discloses a preparation method for the environment-friendly chloroprene adhesive. Processing technologies of mixing and resin pre-reaction are adopted, the operation is simple, the performance is stable, and a product has no de-lamination after being placed at a constant temperature for a long time. Stripping strength for butylbenzene rubber floors and wood materials can achieve material destruction. The adhesive consists of various high polymer ingredients, various tackifying resin and various solvents with different properties and structures, and can beused for the non-structural adhesion of most materials including plastic, rubber, fibers, the wood materials, ceramic, glass, metal and the like.

Description

technical field [0001] The invention relates to the field of chemical materials, in particular to an environment-friendly neoprene adhesive and a preparation method thereof. Background technique [0002] Neoprene adhesives play a pivotal role in rubber adhesives, with good performance, low price, and convenient operation. They are widely used in furniture, shoemaking, decoration, construction, automobiles, rail transit, and electronics. Most of the organic solvents used in traditional chloroprene adhesives are highly toxic solvents such as "triphenyl" (benzene, toluene, xylene) and halogenated hydrocarbons. Although the country has made regulations and restrictions on this, it has not been completely banned. Still use a large amount of toluene, bring very big harm to the health of environment and builder. Although some merchants have developed some low-toxic and environmentally friendly neoprene adhesives, almost all of them contain solvents with strong pungent odors such a...
