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] A tire is a ring-shaped elastic body assembled on a rim or a wheel axle, which is a connecting body between a vehicle and a road, and is used for the running and sliding of a vehicle or an aircraft. A set of tires with an inner tube usually consists of 3 pieces: the outer tire, the inner tube, and the pad. Among them, the outer tire is the outer shell of the tire used to withstand various forces; the inner tube is used to maintain the internal pressure of the tire, and has a circular elastic body with a tire valve; the pad belt is used to protect the inner tire from the wear of the rim. ring belt. The tread is the driving surface, which is the crown part of the tire, that is, the rubber layer of the tire on the belt layer or the buffer layer. It has...
