Abstract

The invention relates to the field of adhesives, in particular to a special heat vulcanization adhesive for shock insulating high damping rubber. The invention discloses a heat vulcanization adhesivefor adhering high damping rubber and a matrix in the shock insulating industry. The heat vulcanization adhesive comprises a crosslinking agent p-dinitrobenzene, halogenated rubber, metal oxides: zincoxide or magnesium oxide and aluminum oxide, inert pigments and filler: carbon black or graphite powder, solvents: aromatic hydrocarbon, a chlorinating solvent or a ketone solvent, a polymaleimide compound: N,N-m-phenylene bismaleimide or diphenylmethane bismaleimide and an adhesion promoter: a trimethylolpropane triacrylate compound and the like. The adhesive has a good adhering effect in high damping rubber in the shock insulating industry.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a heat-vulcanized adhesive special for shock-absorbing high-damping rubber. Background technique [0002] Rubber seismic isolation bearings are the main isolation devices in seismic isolation projects. Among them, ordinary rubber bearings and lead rubber bearings are the most widely used. Lead rubber bearings have good damping performance, but the process of producing lead cores will affect the environment. Pollution, and with the advancement of time in the lead core support, the rubber gradually ages and cracks during use, and the lead core leaks, causing serious damage to the surrounding environment, and the mechanical properties of the lead core rubber support are also affected. different degrees of reduction. Ordinary rubber isolation bearings have a large horizontal stiffness, but the damping ratio of ordinary natural rubber isolation rubber bearings is about 5%. When an earthquake...
