Problems solved by technology

The characteristics of neoprene adhesive are: large initial adhesion, high bonding strength, good durability, flexible adhesive layer, good elasticity, impact and vibration resistance, good oil resistance, water resistance, alkali resistance, acid resistance and solvent resistance. , has good adhesion to wood, easy to use, and low price, but its heat resistance is poor, cold resistance is not good, and storage stability is poor
In order to overcome the shortcomings of traditional neoprene adhesives such as poor heat resistance, poor cold resistance, and poor storage stability, a new type of solvent-based neoprene adhesive is produced by improving the formula.

Abstract

The invention discloses a solvent-based neoprene adhesive. The solvent-based 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, 10-15 parts of epichlorohydrin rubber H45, 5-8 parts of epoxy resin modified polyamide hot-melt adhesive, 2-3 parts of zinc oxide and the like. The adhesive disclosed by the invention has excellent heat resistance, is high in adhesive strength, good in storage stability, good in environmental protection performance, good in use effect and convenient to use and is water-resistant and dampproof.

Description

technical field [0001] The invention relates to an adhesive, in particular to a solvent-type neoprene adhesive. Background technique [0002] Neoprene adhesive has excellent performance and low price, and has good adhesion to rubber, steel, concrete, wood, leather, fabric and other materials. The characteristics of neoprene adhesive are: large initial adhesion, high bonding strength, good durability, flexible adhesive layer, good elasticity, impact and vibration resistance, good oil resistance, water resistance, alkali resistance, acid resistance and solvent resistance. , has good adhesion to wood, is easy to use, and is cheap, but its heat resistance is poor, cold resistance is not good, and storage stability is poor. In order to overcome the disadvantages of traditional neoprene adhesives such as poor heat resistance, poor cold resistance, and poor storage stability, a new solvent-based neoprene adhesive was produced by improving the formula.
