Abstract

The invention provides a composition for damping rubber. The composition comprises rubber, a plasticizer, a vulcanizing agent, an accelerator, an antioxidant, an activating agent, a filler and a softener, wherein the rubber is natural rubber and cis-butadiene rubber; the vulcanizing agent comprises curing resin and sulfur; and the weight ratio of the curing resin to the sulfur is between 1:0.1-10. The invention also provides a method for preparing the composition for damping rubber and the damping rubber obtained through vulcanization of the composition. The composition for damping rubber can remarkably improve fatigue performance and mechanical strength of the damping rubber and can meet the requirement of vehicle damping.

Description

technical field [0001] The present invention relates to a composition for shock-absorbing rubber, its preparation method and the shock-absorbing rubber obtained through the composition. Background technique [0002] In recent years, with the entry of automobiles into ordinary families, people have put forward higher requirements for the comfort of vehicles while enjoying convenience and speed, so the role of shock-absorbing materials is becoming more and more important. Rubber products are widely used as vehicle shock-absorbing material as a kind of elastic material, for example, CN1306030A discloses a kind of vehicle rubber shock-proof pad and its manufacture method, and this rubber shock-proof pad contains the synthetic rubber of 20-30 parts by weight, 5 -10 parts by weight of epoxy resin, 0.5-1 parts by weight of polyamine curing agent, 20-50 parts by weight of filler, 1-3 parts by weight of vulcanizing agent and other additives of 15-25 parts by weight, wherein, the The...
