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

Abstract

The invention discloses a rubber composition with low calorification and low rolling resistance. The rubber composition is prepared by successively carrying out plastification, mixing and vulcanization on rubber based on natural rubber as a rubber raw material and carbon black or white carbon black as a reinforcing agent; in the mixing process of the rubber, silicon carbide micropowder is adopted to replace partial reinforcing agent, a silane coupling agent is added, and the added amounts of the rubber material, the reinforcing agent, the silicon carbide micropowder and the silane coupling agent in the mixing process of the rubber are as follows in parts by weight: 100 part of rubber material, 20-45 parts of carbon black or white carbon black, 5-50 parts of silicon carbide micropowder and 0.4-2.45 parts of silane coupling agent; the silicon carbide micropowder is in an alpha or beta crystal form, and the particle diameter of the silicon carbide micropowder is 0..001mu m-50mu m. According to the invention, the processing performance of the mixed rubber is improved, the compression calorification of vulcanized rubber is reduced, the rolling resistance is obviously reduced, and the slip-wet resistance is improved.

Description

technical field [0001] The present invention relates to a rubber composition, particularly a rubber composition having low heat build-up and low rolling resistance. Background technique [0002] In order to improve the mechanical properties of the vulcanized rubber, carbon black needs to be added to the rubber composition as a reinforcing agent. The reinforcing agent can significantly increase the compression heat generation of the vulcanized rubber while improving the mechanical properties 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 selec...
