Abstract

The present invention discloses a high-performance modified chloroprene rubber adhesive, wherein the raw materials comprise chloroprene rubber, cis-polybutadiene rubber, styrene-butadiene rubber, an alkyl benzoic acid resin, a p-tert-butyl phenol formaldehyde resin, a terpene resin, nanometer silica, nanometer alumina, organic bentonite, white carbon black, active magnesium oxide, polystyrene, ethylene thiourea, zinc oxide, ethyl acetate, cyclohexane, dimethyl carbonate, propylene glycol, methyl cyclopentane, 120# solvent oil, a resorcinol-formaldehyde resin, an anti-aging agent, cerium oxide, a silane coupling agent KH-560 and a plasticizer. According to the present invention, the high-performance modified chloroprene rubber adhesive has characteristics of high bonding strength, good low temperature resistance, good weather resistance, good heat resistance, good aging resistance, and excellent storage stability.

Description

technical field [0001] The invention relates to the technical field of neoprene rubber adhesives, in particular to a high-performance modified neoprene rubber adhesive. Background technique [0002] Neoprene is the main raw material of neoprene adhesive, its molecular structure is regular, and there are polar chlorine atoms on the molecular chain, which makes neoprene have high cohesive strength and flame resistance at room temperature And the aging resistance is good, the adhesive formulated with it can be cold-cured at room temperature, the initial adhesion is very large, the strength is quickly established, and the bonding strength is high. It can be used for bonding rubber, leather, fabric, Artificial leather, plastic, wood, paper, glass, ceramics, etc. However, neoprene adhesives have the disadvantages of poor storage stability, unsatisfactory low temperature resistance, weather resistance and heat resistance, which limit their application range. Contents of the inve...
