Abstract

Rubber used for solid tyres and a preparing method thereof are disclosed. The rubber includes natural rubber, butadiene-acrylonitrile rubber, polybutadiene, 2-hydroxyethyl acrylate, graphene, nanometer titanium dioxide, stearic acid, an antioxidant, a vulcanizing agent, a coupling agent and a filler. The method includes adding polymer into an internal mixer, plastifying the polymer, then adding the graphene, the 2-hydroxyethyl acrylate and the silane coupling agent, blending the mixture, then adding the rest components in order, and discharging the rubber after blending is finished to obtain the rubber used for solid tyres. The rubber has good shaping effects, and has good using properties such as wear resistance, corrosion resistance and weatherability. The rubber is used for preparing the solid tyres and provides a guarantee for automobile using safety.

Description

technical field [0001] The invention relates to the technical field of solid tires, in particular to a rubber for solid tires and a preparation method. Background technique [0002] As the main accessories of automobiles, tires are unavoidable to be worn and punctured during use, especially when a tire blows out in a high-speed automobile, it is very easy to cause serious accidents such as car crashes and fatalities. Therefore, various manufacturers are constantly improving the safety, environmental protection, and energy-saving requirements of tires. In order to prevent tires from exploding, existing automobiles generally use the tubeless vehicle wheel, and the country for heavy-duty vehicles requires progressively promoting the use of the tubeless vehicle wheel. Solid tires are generally used under high loads, and the rubber compound is required to have sufficient pressure resistance and wear resistance, high enough modulus stress, high hardness, low permanent deformation...
