Motorcycle tire tread rubber material with skid and wear resistance and preparation method thereof

Abstract

The invention discloses a motorcycle tire tread rubber material with skid and wear resistance and a preparation method thereof. The rubber material comprises SSBR (solution polymerized styrene-butadiene rubber) 2564, butadiene styrene rubber, butadiene rubber, carbon black, zinc oxide, octadecanoic acid, an anti-aging agent, sulfur, aromatic hydrocarbon oil, an accelerant, a reinforcing agent, a thickening agent and a dispersing agent, wherein the aromatic hydrocarbon oil is high aromatic hydrocarbon oil, a silane coupling agent is further added, insoluble sulfur is adopted, and the rubber material is prepared through steps of plastication, mixing, open milling and the like. According to the tire tread material composition and the preparation method thereof, the obtained rubber material has better breaking strength, tensile strength and hardness; with the adoption of the raw materials with skid and wear resistance and through matching of reasonable composition design, the potential hazard to a processor and a user during production and use processes is greatly reduced, and safety, economic efficiency and adaptability of the product are wider; and with the adoption of the SSBR and the white carbon black, the slippery resistance of the tread rubber is remarkably improved, and meanwhile, the wear resistance is improved by means of the hard wear-resistant carbon black.

Description

technical field [0001] The invention belongs to a rubber material combination for motorcycle tire treads and a preparation method thereof, in particular to a rubber material combination for motorcycle tire treads with both anti-skid and wear resistance properties and a preparation method thereof. Background technique [0002] Traditional tread rubber formulations generally use rubber types such as NR, SBR and BR. SBR can improve the tire's wet skid resistance and handling performance, but increases the rolling resistance; NR and BR are beneficial to reduce the rolling resistance, but the wet skid resistance and handling performance are poor. It has a higher loss factor at a lower temperature such as 0°C, and has a lower loss factor at a higher temperature such as about 70°C, which reduces rolling resistance, that is, polymers with low glass transition temperatures have lower rolling resistance and high glass transition temperatures. The polymer is beneficial to improve the ...

Problems solved by technology

Tires are made up of a variety of materials. An ordinary tire’s service life and anti-skid performance are its important performance indicators. There are two situations in current tires: one is that the anti-skid performance of the tire meets the national standard and the needs of consumers, but the tire The wear resistance requirements cannot meet the standard; the second is that the tire wear resistance has reached the standard, but the anti-skid performance of the tire cannot be better guaranteed

In addition, most of the existing tire damage is caused by the short-term wear of the tread. Therefore, more and more attention has been paid to tires with anti-skid and wear resistance, and people have paid more and more attention to the anti-skid and wear resistance of tires. As far as the current tire industry is concerned, it is necessary to continue to explore and develop research on meeting the requirements of anti-skid and wear resistance, meeting the requirements of comprehensive tire performance, and achieving better results in terms of tire material cost and processing cost.
