Abstract

The invention belongs to the technical field of rubber manufacturing, and in particular relates to ozone aging resistant sidewall rubber applied to a saloon semisteel radial tire. The ozone aging resistant sidewall rubber applied to the saloon semisteel radial tire is prepared from the following raw materials in parts by weight: acrylic rubber, chlorinated butyl rubber, brimstone, carbon black N339, aromatic oil, stearic acid, zinc oxide, N,N'-di(1,4-dimethyl butyl)-p-phenylenediamine, tri(N-1,4-dimethylphenyl-diamino benzene)-1,3,5-triazine, and N-(1,3-dimethyl butyl)N'-phenyl-p-phenylenediamine. The sidewall rubber has excellent properties of ozone aging resistance and cracking resistance, contains no wax, and avoids the problems of viscosity drop of size, and over-blooming of surface.

Description

technical field [0001] The invention belongs to the technical field of rubber production, and in particular relates to an ozone-aging-resistant sidewall rubber for semi-steel radial tires for cars. Background technique [0002] The tire is a ring-shaped elastic body that is assembled on the rim or axle and is the connecting body between the vehicle and the road, which is used for the running and sliding of the vehicle or the aircraft. A set of tires with an inner tube usually consists of 3 pieces: the outer tire, the inner tube, and the pad. The outer tire is the outer casing of the tire used to withstand various forces; the inner tube is used to maintain the internal pressure of the tire, and the annular elastic body with the tire valve; the gasket is used to protect the inner tire from the wear of the rim. endless belt. The tread is the running surface, which is the crown part of the tire, that is, the tire rubber layer on the belt layer or the buffer layer. It has a cer...
