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 compound and a preparation method thereof, and particularly relates to an environmentally friendly tire tread rubber compound and a preparation method thereof. Background technique [0002] The tire is made up of a variety of materials. A common tire uses more than 20 materials, most of which are petroleum products. The European Union officially implemented the RoHS directive on July 1, 2006, and on January 1, 2010. The REACH regulations are formally implemented, both of which stipulate that tires must not contain substances harmful to the environment. With the rapid development of social economy today, environmental protection has received more and more attention, and environmentally friendly tires have also become the development trend of the tire industry. People are paying more and more attention to the coexistence of environmental protection and performance of tires, but in terms of current tire types, ther...
