Abstract

The invention discloses a high-temperature-resistant and low-temperature-resistant environment-friendly chloroprene rubber adhesive, which is prepared from the following components in parts by weight:100 parts of chloroprene rubber compound, 100-400 parts of hydrocarbon solvent oil and 100-400 parts of ethyl acetate. The chloroprene rubber compound is prepared by mixing chloroprene rubber, zinc oxide, magnesium oxide, an accelerant MTT-80, an accelerant DM, stearic acid, carbon black, an anti-aging agent and a maleic anhydride graft polymer. The invention also discloses a preparation method of the high-temperature-resistant and low-temperature-resistant environment-friendly chloroprene rubber adhesive, which comprises the following steps: soaking the chloroprene rubber compound in a hydrocarbon solvent oil-ethyl acetate mixed solvent for 3-5 hours, and stirring the mixture for 4-6 hours until the mixture is uniform. The chloroprene rubber adhesive disclosed by the invention is environment-friendly and has little harm to a human body and the environment; the adhesive disclosed by the invention has the advantages of high and low temperature properties, wide applicability, high bonding strength and wide materials of a bonded matrix, and the bonding of chloroprene rubber with nylon cords, vinylon cords and polyester cords is improved.

Description

technical field [0001] The invention belongs to the technical field of adhesives and relates to an adhesive, in particular to a low-temperature resistant and environment-friendly neoprene adhesive and a preparation method. Background technique [0002] Rubber adhesive is an indispensable material in production and life, especially widely used in light industrial production. With the development of science and technology and the improvement of people's living standards, there are further requirements for the quality of rubber products. [0003] The toxicity of solvents and additives used in adhesives is an urgent issue that needs to be considered. The tackifier used in the traditional preparation of chloroprene rubber adhesives is usually a chelate of tert-butylphenolic resin and magnesium oxide. There is a certain amount of free formaldehyde in the phenolic resin. The release of free formaldehyde is a slow process. The above unfavorable factors continue to affect the envir...
