Abstract

The invention discloses high strength high elasticity rubber. The high strength high elasticity rubber comprises constant viscosity natural rubber, zinc oxide, stearic acid, an antioxidant RD, an antioxidant 4010NA, carbon black N550, carbon black N330, poly-sulfur, N-oxydiethylene-2-benzothiaolesulfenamide, dibenzothiazyl disulfide, tetramethylthiuram disulfide, and a scorch retarder CTP. Compared with the prior art, the hardness of the high strength high elasticity rubber is equal to or greater than 82, the tensile strength of the high strength high elasticity rubber is equal to or greater than 18Mpa, the elongation at rupture of the high strength high elasticity rubber is equal to or greater than 350%, the compression permanent deformation of the high strength high elasticity rubber isless than 22% and the resilience of the high strength high elasticity rubber is greater than 50% through the model and dosage selection of above materials.

Description

technical field [0001] The present invention relates to rubber, in particular to high-hardness and high-elasticity rubber used for automobile shock absorbing product "bushing". Background technique [0002] The rubber of the shock absorbing product "bushing" currently used in automobiles has a hardness of 15, a tensile strength of 15Mpa, an elongation at break of 320%, a compression set of 28%, and a resilience of 35%. The permanent deformation rate is 28% (70°C×22h), and the rubber with the above properties is far from meeting the actual needs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-strength, high-elastic rubber with a rubber resilience greater than 65%. [0004] The technical scheme for solving technical problems of the present invention is: a kind of high-strength, high-elastic rubber, containing the following substances by weight: [0005] [0006] [0007] Preferred high-strength, hig...
