Abstract

The invention discloses synthetic rubber for a high-speed tire. The synthetic rubber comprises the following components in parts by weight: 67 parts of chlorosulfonated polyethylene, 39 parts of butadiene-acrylonitrile rubber, 13 parts of fast extruding furnace black, 20 parts of heat-cracking soot, 2-4 parts of indirect-process zinc oxide, 3-5 parts of magnesium oxide, 0.2-1 part of zinc diethyl dithiocarbamate, 0.4-1.5 parts of dilauryl thiodipropionate, 0.5-1 part of zinc stearate, 2-4 parts of 2,2'-dithiobenzothiazole, 0.3-0.5 part of trimerization thiocyanic acid, 5-8 parts of trioctyl trimellate, 1-5 parts of strong magnesium powder, 2-3 parts of sulfur and 2-3 parts of isoamyl IR. According to the synthetic rubber for high-speed tire disclosed by the invention, the defects such as low high-temperature resistance, aging simplicity and short service life in the prior art can be overcome, so that the advantages of high high-temperature resistance, aging difficulty and long service life are realized.

Description

technical field [0001] The invention relates to automobile rubber hose technology, in particular to a synthetic rubber for high-speed tires. Background technique [0002] Rubber is an elastic polymer. Rubber can be obtained from the sap of some plants, or it can be man-made. Both have quite a lot of applications and products, such as tires, gaskets, etc., and have become important economic crops. Rubber plantations are mainly concentrated in Southeast Asia, such as Thailand, Malaysia, and Indonesia. [0003] After rubber was introduced to Britain, people found that this material could effectively wipe off the traces left by pencils, so the eraser was invented. The English name of rubber is rubber. In 1770, Priestley, England, discovered that this substance could erase (rub off) pencil marks. According to the different ways of making, rubber can be divided into two categories: synthetic rubber and natural rubber. [0004] In the process of realizing the present invention,...
