Problems solved by technology

[0004] In recent years, in order to improve the wet grip performance of the tread, many R&D personnel have tried to use solution-polymerized styrene-butadiene rubber, butadiene rubber, foam rubber, silica, high hardness and insoluble rubber in the semi-steel tread. Solid particles and water-soluble crystal salts (such as sodium chloride, magnesium sulfate), etc., these methods are difficult to achieve on all-steel tires, because the load of all-steel tires is relatively large, and the requirements for the viscosity and strength of rubber are high, so its The main component of tread rubber is natural rubber, and the above methods have certain shortcomings

Embodiment 1

[0021] An all-steel truck tread compound, said compound comprising 70 parts by weight of natural rubber, 30 parts of epoxidized natural rubber ENR, 1-6 parts of zinc acrylate ZDA, 45 parts of carbon black N1154, zinc oxide 4 parts, 1.5 parts of stearic acid, 2.8 parts of antioxidant 6PPD, 3 parts of microcrystalline wax, 1.7 parts of oil-extended sulfur, 0.9 parts of accelerator NS, 1.2 parts of accelerator DPG, and 0.18 parts of anti-scorch agent CTP.

[0022] The preparation method of the above-mentioned all-steel truck tread compound is carried out according to the following steps:

[0023] (a) Proportionally mix 1 / 3 of the total amount of epoxidized natural rubber ENR with zinc acrylate ZDA in an open mill and pre-disperse for 2 minutes; then put natural rubber and all epoxidized natural rubber ENR into Carry out mastication in the internal mixer for 20-40s, the mixing temperature is 40°C, the speed is 55-30rpm, first fast and then slow, and the pressure of the top bolt is...

Abstract

The invention relates to an all-steel truck tread rubber material which comprises the following components in parts by weight: 70 parts of natural rubber, 30 parts of epoxidized natural rubber ENR and1-6 parts of zinc acrylate ZDA. The rubber material also comprises 45 parts of carbon black N115, 4 parts of zinc oxide, 1.5 parts of stearic acid, 2.8 parts of an anti-aging agent 6PPD, 3 parts of microcrystalline wax, 1.7 parts of oil-extended sulfur, 0.9 parts of an accelerator NS, 1.2 parts of an accelerator DPG and 0.18 parts of an anti-scorching agent CTP. According to the invention, the wet grabbing performance and the cutting resistance can be obviously improved.

Description

technical field [0001] The invention relates to an all-steel truck tread compound and a preparation method thereof. Background technique [0002] High wet grip performance can reduce the braking distance of the car during driving and improve driving safety; high cutting resistance can prolong the service life of tires, especially truck tires working in mines, because there are many debris on the road surface of mines The average service life of stone and mine tires is 1 to 2 months, and improving the cutting resistance of the tread rubber is beneficial to prolong the service life of the tires. [0003] According to market analysis, the output of all-steel radial tires in my country currently accounts for about 1 / 4 of the total output, and the service life of tires has always been a concern for drivers in the transportation industry. 80% of the service life of all-steel tires is related to the wear and tear of the tire tread, related to cut resistance. In addition, as driver...
