Abstract

The invention discloses an antistatic wear-resistant solid tire core and preparation method thereof. The tire core comprises the following components: nitrile rubber, styrene butadiene rubber, natural rubber, acrylic resin, a silane coupling agent, graphene, white carbon black, carbon black, glass fiber, bamboo charcoal fiber, nano silica, activated zinc oxide, an antioxidant, a promoter, a vulcanizing agent and filler. The preparation method comprises the following steps: mixing a rubber raw material in an internal mixer, then adding residual components by batches for mixing, discharging rubber after mixing, dumping the material in a forming die for molding to obtain the molded tire; polishing the tire under normal temperature, and removing foreign matter to obtain the product. The tire core has good wear resistant performance, greatly increases the tire service life, has good antistatic effect, and provides guarantee for safety usage of the automobile.

Description

technical field [0001] The invention relates to the technical field of solid tires, in particular to an antistatic and wear-resistant solid tire core and a preparation method. Background technique [0002] As the main parts of automobiles, tires are inevitably worn and leaked after being punctured during use. Especially in the case of tire blowouts in high-speed cars, it is very easy to cause serious accidents that cause car crashes. Therefore, the requirements of various manufacturers on the safety, environmental protection and energy saving of tires are constantly improving. In order to prevent the tires from exploding, the existing automobiles generally use tubeless vehicle wheels, and the heavy-duty vehicle country requires the gradual promotion of the use of tubeless vehicle wheels. Solid tires are generally used under high loads, and the rubber compound is required to have sufficient pressure resistance and wear resistance, high enough tensile stress, high hardness, l...
