Problems solved by technology

The manufacturing cost and equipment investment of this method are large, the labor intensity of workers is high, and the problem of environmental pollution is difficult to solve
[0003] In addition, traditional neoprene adhesives contain more benzene solvents. The current national standard "GB18583-2001" stipulates that benzene is less than 0.5% and benzene plus xylene and toluene are less than 20% for solvent-based rubber adhesives. Benzene solvents below 20%, these solvents are not conducive to environmental protection, and are not conducive to the physical and mental health of builders

Abstract

The chloroprene rubber adhesive is prepared with chloroprene rubber, cyclopentane-B solvent, methyl ethyl ketone, ethyl acetate, No. 120 solvent gasoline, tert-butyl phenolic resin, magnesium oxide, zinc oxide and benzoic acid-water catalyst. The present invention uses no toxic benzene solvent, and has less environmental pollution and harm to human body, and the product has good brushing performance, high adhesive strength, high lasting property and other advantages.

Description

technical field [0001] The invention belongs to the technical field of adhesives, in particular to a neoprene adhesive and a preparation method thereof. Background technique [0002] Neoprene adhesive is a solvent-based adhesive, which has good cohesiveness and is known as "universal adhesive". The traditional preparation method of neoprene adhesive is to use rubber mixer to roll and masticate the polymer to cut the molecular chain and destroy the gel in the polymer, so as to improve the consistency of the solution, and add some Metal oxides to make it uniform and smooth, and then cut the kneaded film into strips and granules, and dissolve it in a solvent in a closed container with a stirrer or a high-speed mixer. The manufacturing cost and equipment investment of this method are relatively large, the labor intensity of workers is high, and the problem of environmental pollution is difficult to solve. [0003] In addition, traditional neoprene adhesives contain more benzen...
