Problems solved by technology

People pay more and more attention to the coexistence of tire environmental protection and performance, but there are generally two situations in terms of the current tire form: one is that the performance of the tire can meet the national standard and the needs of consumers, but the tire cannot meet the environmental protection requirements of the European Union; two. It is the tire that can meet the requirements of environmental protection, but the performance of the tire cannot be guaranteed

Abstract

The invention discloses an environmentally-friendly size composition for a tyre surface of a tyre and a preparation method thereof. The environmentally-friendly size composition comprises natural rubber, butadiene styrene rubber, butadiene rubber, carbon black, zinc oxide, stearic acid, an antiager, C5 resin, insoluble sulfur, environmentally-friendly arene oil, an accelerator and a homogenizing agent and various other components. The environmentally-friendly size can be prepared by the steps of plastifying and mixing the raw materials and the like. The environmentally-friendly size composition for the tyre surface of a tyre and size obtained by using the preparation method have better breaking strength, tensile strength and hardness, meet environmentally-friendly requirement and are prepared from environmentally-friendly raw materials which do not contain harmful substances, wherein arene oil, C5 resin, insoluble sulfur, carbon black and the like belong to the environmentally-friendly materials; and through adopting the environmentally-friendly raw materials coordinated with reasonable composition design, the environment pollution hidden danger caused in the production and use processes is greatly reduced, and the product has wider safety, economy and adaptability.

Description

technical field [0001] The invention belongs to a tire tread rubber material combination and a preparation method thereof, in particular to an environment-friendly tire tread rubber material combination and a preparation method thereof. Background technique [0002] Tires are composed of a variety of materials. An ordinary tire uses more than 20 materials, most of which are petroleum products. The EU officially implemented the RoHS directive on July 1, 2006, and on January 1, 2010 Officially implement the REACH regulations, both of which stipulate that the tires must not contain substances that are harmful to the environment. Today, with the rapid development of social economy, more and more attention is paid to environmental protection, and environmentally friendly tires have become the development trend of the tire industry. People pay more and more attention to the coexistence of tire environmental protection and performance, but there are generally two situations in ter...
