Abstract

The invention provides a novel rubber-metal hot vulcanization type adhesion agent. The adhesion agent comprises a cross-linking agent, halogenated rubber, mixed metal oxide, a polymaleimide compound, a vulcanizing agent, inert filler and a solvent, wherein the cross-linking agent is a mixture of epoxy acrylate, trimethylolpropane trimethacrylate and sodium hydrogen sulfite closed toluene diisocynate; the mixed metal oxide is a mixture of zinc oxide, molybdenum oxide and cobaltous oxide. A ratio of the three components in the cross-linking agent and a ratio of the components in the mixed metal oxide are adjusted and the components are matched for use, so that cobalt in the metal oxide is more easily transferred and diffused to a crystal lattice bonded with metal and reacts with the metal, further, the cross-linking agent in the adhesion agent is promoted to have a chemical reaction with rubber rapidly, and accordingly, the adhesion process is more rapid and the adhesion strength is higher.

Description

technical field [0001] The invention relates to a rubber-metal thermal vulcanization adhesive composition for rapid vulcanization rubber bonding. It can bond quickly when heated and pressurized in the vulcanization process, which can greatly improve the working efficiency of the production line.
