Problems solved by technology

Compression heat generation has a great influence on the performance of rubber products that need to be repeatedly deformed. If the compression heat generation is too large, the rubber product will heat up rapidly. The temperature rise not only accelerates the thermo-oxidative aging of rubber, but also may cause rubber products to deteriorate due to excessive temperature. the destruction of

Embodiment Construction

[0011] A rubber composition with low compression heat generation and low rolling resistance, which is made by using synthetic rubber as the rubber raw material, carbon black or white carbon black as the reinforcing agent, and sequentially undergoing rubber mastication, mixing and vulcanization processes, Wherein the mastication, mixing and vulcanization processes of the rubber are carried out according to the usual process methods. But in order to realize the object of the present invention, in rubber mixing process, adopt silicon carbide fine powder to replace part reinforcing agent, and add silane coupling agent, rubber raw material, reinforcing agent, silicon carbide fine powder and silane coupling agent in rubber mixing process The ratio of parts by weight of the amount of coupling agent added is: 100 parts of rubber raw material, 45-70 parts of carbon black or white carbon black, 5-50 parts of silicon carbide micropowder, 0.4-2.45 parts of silane coupling agent, and the sy...

Abstract

A rubber composition with low compression heat and small rolling resistance is prepared by taking synthetic rubber as a raw material and carbon black or white carbon black as a reinforcing agent sequentially carrying out plastication, mixing and vulcanization processes of rubber. In the mixing process of the rubber, silicon carbide micro powder is adopted to replace part of reinforcing agent and a silane coupling agent is added; 100 parts by weight of rubber raw material, 45-70 parts by weight of carbon black or white carbon black, 5-50 parts of silicon carbide micro powder and 0.4-2.45 parts of silane coupling agent are added in the mixing process of the rubber; and the synthetic rubber is butadiene styrene rubber of which the content of bound styrene is 15-50 percent and the Mooney viscosity is 30-90. The processing performances of mixed rubber are improved; the compression heat of vulcanized rubber is reduced, the rolling resistance is remarkably reduced and the wet sliding resistance is improved.

Description

technical field [0001] The present invention relates to a rubber composition, in particular to a rubber composition with low compression heat generation and low rolling resistance. Background technique [0002] In order to improve the mechanical properties of the rubber, carbon black needs to be added to the rubber composition as a reinforcing agent. The reinforcing agent improves the mechanical properties of the vulcanized rubber while significantly increasing the compression heat generation of the vulcanized rubber. Compression heat generation has a great influence on the performance of rubber products that need to be repeatedly deformed. If the compression heat generation is too large, the rubber product will heat up rapidly. The temperature rise not only accelerates the thermo-oxidative aging of rubber, but also may cause rubber products to deteriorate due to excessive temperature. destruction. Car tire blowout in summer driving is a typical example. In addition to sel...
