Problems solved by technology

Due to its molecular group, silica has insufficient compatibility with rubber, and it is difficult to obtain the required dispersion effect. Therefore, improving the fatigue resistance of tire rubber has always been the bottleneck of the existing technology.

Abstract

The invention discloses an anti-fatigue tire compound and its preparation method. The anti-fatigue tire compound is prepared from, by weight, 100 parts of alkadiene rubber, 30-50 parts of white carbon black, 0-10 parts of carbon black, 3-5 parts of active agent, 1-3 parts of anti-aging agent, 2-4 parts of bonding agent, and 6-10 parts of softening agent. According to the anti-fatigue tire compound, the rubber compound or final compound has very high anti-fatigue without adding the non-environmental-friendly antifatigue during the preparation process of the tire compound; through being detected by a carbon black dispersion tester, the dispersion grade of the prepared tire rubber can stably reach 7 and above; the fatigue test or the yield after thermal aging of the tire compound can be free from crack for 1.2 million times.

Description

technical field [0001] The invention relates to the technical field of tire rubber materials, in particular to an anti-fatigue tire rubber material and a preparation method thereof. Background technique [0002] At present, in tire manufacturers, most of the anti-fatigue agents are added to the rubber compound to achieve the same performance index. The amount of anti-fatigue agent is relatively large, and most of them are controlled above 5PHR, but the fatigue test (after heat aging) Flexion) is also 300,000-700,000 times. Most of the anti-fatigue agents on the market are non-environmental protection products and may be banned in the future. With the further promotion and implementation of environmental protection awareness in the people's livelihood industry, all walks of life are speeding up the rectification, and the carbon black used in the tire industry has pollution effects due to its production process, and the production of white carbon black is relatively clean.
