Embodiment 1

[0030] The invention proposes a wear-resistant tread formula, including the following raw materials in parts by weight: 40 parts of rubber, 1 part of anti-aging agent, 10 parts of carbon black, 5 parts of sulfur, 10 parts of nano-zinc oxide, 1 part of stearic acid, 1 part of magnesium hydroxide, 1 part of aluminum hydroxide, 3 parts of n-phenylmaleimide, 5 parts of calcium stearate, 1 part of phenyl silicone oil;

[0031] Its preparation method comprises the following steps:

[0032] S1: Mix rubber, sulfur, nano zinc oxide, stearic acid, magnesium hydroxide, aluminum hydroxide, n-phenylmaleimide, calcium stearate, and phenyl silicone oil for 1 min. The mixing temperature is 80°C, then add anti-aging agent and carbon black and mix at a mixing temperature of 90°C to make a film;

[0033] S2: The film outlet water is cooled by the cooling water tank. The cooling steps are: first blow the fan to cool, and then carry out natural cooling and air conditioning cooling;

[0034] S3: ...

Abstract

The invention belongs to the field of tires, particularly relates to a wear-resistant tire tread formula, and provides the following scheme aiming at the problems of poor wear resistance and heat resistance of an existing tire tread: the wear-resistant tire tread formula comprises the following raw materials in parts by weight: 40-60 parts of rubber, 1-5 parts of an anti-aging agent, 10-15 parts of carbon black, 5-10 parts of sulfur, 10-15 parts of nano-zinc oxide, 1-5 parts of stearic acid, 1-5 parts of magnesium hydroxide, 1-5 parts of aluminum hydroxide, 3-8 parts of n-phenylmaleimide, 5-10 parts of calcium stearate and 1-5 parts of phenyl silicone oil. The wear-resistant tire tread formula has good wear resistance and high temperature resistance, and the preparation method is simple.

Description

technical field [0001] The invention relates to the field of tires, in particular to a wear-resistant tread formula. Background technique [0002] Tread refers to the tire rubber layer above the buffer layer or belt layer at the crown, or the tire running surface where the tire is in contact with the ground. It consists of crown rubber, base rubber and tread lower rubber. Its function is to prevent the carcass from mechanical damage, transmit the traction and braking force of the vehicle, and buffer the impact of the tire during driving. It is required to have good wear resistance, puncture resistance, good elasticity and grip performance on the ground. [0003] The existing tread has poor wear resistance and heat resistance, so we propose a wear-resistant tread formula to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to solve the disadvantages of poor tread wear resistance and heat resistance in the prior art, and ...
