Problems solved by technology

The car is an outdoor product that needs to be exposed to the sun for a long time, and it also needs to be rubbed against the ground during use. The rubber used in traditional tires is prone to aging under long-term sun exposure, which affects the elasticity of the rubber and makes the tire The compression resistance of the tire is reduced, and the friction with the ground for a long time will cause serious wear and deformation of the ordinary rubber, which will reduce the service life of the tire and affect the overall performance of the car.

Abstract

The invention discloses an anti-aging automobile rubber tire material. The anti-aging automobile rubber tire material comprises the following raw materials in parts by weight: 100-120 parts of neoprene raw rubber, 50-100 parts of butadiene raw rubber, 1-3 parts of dipentamethylenethiuram tetrasulfide, 0.5-1.5 parts of dicumyl peroxide, 3-5 parts of lead dimethyl phosphate, 1-4 parts of paraffin oil, 2-6 parts of oxidized polyethlene wax, 2-6 parts of tween, 2-6 parts of sulfur, 20-30 parts of a filling agent, 1-3 parts of a plasticizer, 2-4 parts of a coupling agent and 3-6 parts of an initiator. The rubber tire material is good in aging resistance and high in pressure resistance and wear resistance, in a preparation process, the mixing efficiency is high, the vulcanization time is short,and scorching is unlikely to cause.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to an anti-aging automobile rubber tire material. Background technique [0002] With the improvement of people's quality of life, people's requirements for material life are getting higher and higher, and the family ownership of cars is also increasing. Rubber has high elasticity, so it is widely used in automobile tires. Car tires are an essential part of a car, which must carry the weight of the entire car and maintain contact and friction with the ground. The car is an outdoor product that needs to be exposed to the sun for a long time, and it also needs to be rubbed against the ground during use. The rubber used in traditional tires is prone to aging under long-term sun exposure, which affects the elasticity of the rubber and makes the tire The compression resistance of the tire is reduced, and the friction with the ground for a long time will cause serious wear and d...
