Abstract
The invention discloses a neoprene adhesive for woodworking. The neoprene adhesive is prepared from the raw materials in parts by weight: 100-120 parts of styrene, 100-150 parts of ethyl acetate, 20-25 parts of neoprene CR121, 15-20 parts of dimethylbenzene, 1-2 parts of 4,4'-diphenylmethane diisocyanate, 8-12 parts of polyisobutylene, 2-3 parts of 3-aminopropyl trimethoxysilane, 2-3 parts of polytetrahydrofuran ether glycol, 3-5 parts of SG-2 PVC (Polyvinyl Chloride) resin, 1-2 parts of ferrocene, 8-12 parts of cis-1,4-polyisoprene rubber, 5-8 parts of ethylene propylene terpolymer and the like. The adhesive disclosed by the invention has excellent heat resistance and cold resistance, is high in adhesive strength, good in storage stability, good in environmental protection performance, good in use effect and convenient in use and is water-resistant and dampproof.
Description
technical field [0001] The invention relates to an adhesive, in particular to a neoprene adhesive for woodworking.
