Abstract

The present invention relates to a preparation method for a chloroprene rubber adhesive, especially to a preparation method for a directly-dissolved chloroprene rubber adhesive. The raw materials of the directly-dissolved chloroprene rubber adhesive comprise, by weight, 9-15.5% of chloroprene rubber, 3.8-4.2% of a resin, 27.4-28.9% of 120# oil, 4.4-12.2% of a ketone, 47.2-54.2% of an ester, and 0.02% of magnesium oxide. The chloroprene rubber adhesive synthesized by the process of the present invention has characteristics of high bond strength, good stability, no layering, high temperature resistance, low temperature resistance, cheap price, and no requirement of the prefabricated reaction solution. The preparation method of the present invention has characteristics of process simplifying, operation reducing, time saving and efficiency improving.

Description

technical field [0001] The invention relates to a preparation method of a neoprene adhesive, in particular to a preparation method of a direct-melting neoprene adhesive. Background technique [0002] Neoprene adhesive is a kind of rubber adhesive used in a large amount. It has strong initial adhesion, high bonding strength, heat resistance, and weather resistance. It has irreplaceable characteristics of other adhesives and is widely used. The traditional neoprene adhesive preparation method is to use a rubber mixer to masticate and mix the film to cut the molecular chain, so as to destroy the gel in the polymer and reduce the solution viscosity. The accelerator is added during the mixing process, and then the mixed film is cut into strips and dissolved in a solvent in a closed container with a stirrer. The method has large manufacturing cost and equipment investment, high energy consumption, complex process and low efficiency. With the development of the economy, the amoun...
