Abstract

The invention discloses a radial tire with good aging resistance, and a preparation method of the radial tire. The radial tire is mainly prepared from the following raw materials: butadiene rubber, solution polymerized styrene-butadiene rubber, natural rubber, super wear-resistant carbon black, zinc oxide, stearic acid, an anti-aging agent NBC, pentaerythrityl tetraisostearate, coal pitch, sublimed sulfur, a scorch retarder CTP, iron sodium titanate lamella, aluminum phosphite, and the like. In the method, the butadiene rubber, the natural rubber and the solution polymerized styrene-butadiene rubber are taken as main raw materials, and the whole performance of the natural rubber is excellent; the butadiene rubber is low in friction coefficient and good in thermo-oxidative aging resistance; the solution polymerized styrene-butadiene rubber is better in crack growth resistance and is especially better in wet-skid resistance and balance of rolling resistance; therefore, by the matching of the butadiene rubber, the natural rubber and the solution polymerized styrene-butadiene rubber, the defects of the performance of a single type of rubber can be overcome; the bonding strength among all the components is improved by 3-glycidyl ether-base oxy propyl methyl dimethoxy silane; by adding the raw materials such as natural colored sand and the iron sodium titanate lamella into the radial tire, the aging resistance and the wear resistance of the radial tire are further improved.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to a radial tire with good aging resistance and a preparation method thereof. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on metal rims, it can support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, which...
