Fast-curing chloroprene rubber adhesive and preparation method thereof

Abstract

The invention discloses a fast-curing chloroprene rubber adhesive, which is prepared by the following raw materials in part by weight: 100-120 parts of styrene, 100-150 parts of ethyl acetate, 120-25 parts of chloroprene rubber CR12, 15-20 parts of dimethyl benzene, 1-2 parts of 4,4'- diphenyl methane diisocyanate, 8-12 parts of polyisobutene, 2-3 parts of 3-aminopropyl trimethoxysilane, 2-3 parts of polytetramethylene ether glycol, 3-5 parts of SG-2 type PVC (polyvinyl chloride) resin, 1-2 parts of ferrocene, 8-12 parts of cis-1,4-polyisoprene resin, 5-8 parts of chloroprene rubber CR322, 5-8 parts of epoxidized soybean oil, 3-5 parts of glycerol triacetate and the like. The adhesive is excellent in heat resistance and cold tolerance, high in bonding strength, high in curing speed, waterproof, moisture-proof, good in storage stability and environment protection, good in using effect, convenient, wide in application range, suitable for bonding of artificial leather, synthetic leather, plastics, nylon and organic glass, and further suitable for the shoemaking industry.

Description

technical field [0001] The invention relates to a fast neoprene adhesive and a preparation method thereof, belonging to the technical field of chemical industry. Background technique [0002] Neoprene is a synthetic rubber compound that is produced in large quantities to make adhesives for a wide range of applications. The structure of chloroprene rubber is relatively regular, and there are chlorine atoms with high polarity, so it has high crystallinity. It has good bonding performance and high cohesive strength at room temperature, and is very suitable as an adhesive. 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 a variety of materials, easy to use, and low price, but poor heat resistance, poor cold resistance, poor s...

AI Technical Summary

Problems solved by technology

The structure of chloroprene rubber is relatively regular, and there are chlorine atoms with high polarity, so it has high crystallinity. It has good bonding performance and high cohesive strength at room temperature, and is very suitable as an adhesive. 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 a variety of materials, easy to use, low price, but poor heat resistance, poor cold resistance, poor storage stability, slow curing speed

In order to overcome the shortcomings of traditional neoprene adhesives such as poor heat resistance, poor cold resistance, poor storage stability, and slow curing speed, a fast-curing neoprene adhesive is produced by improving the formula.
