Abstract

The invention discloses a preparation method of a lightweight wear-resistant rubber material. According to the process, the lightweight wear-resistant rubber material is prepared from raw materials such as 2,2-bis(4-hydroxyphenyl)butane, sodium chloride, triethyl acetyl citrate, isoprene rubber, ethylene-vinyl acetate copolymer, chlorohydrine rubber, natural bamboo fibers, white carbon black, 2,2,4-trimethyl-1,2-dihydro-quinoline polymer, gamma-methacryloxy propyl trimethoxyl silane, sodium o-hydroxybenzoate, carbamide, diammonium phosphate, triphenylethylene, a defoaming agent and stabilizermixed solution, sulfur powder and a vulcanizer by the steps such as reflux reaction, high-temperature pressurized reaction, ultrasonic dispersion, double-screw extrusion, plate vulcanization, high-temperature setting and curing, cooling and air drying. The prepared lightweight wear-resistant rubber material is small in dense mass, low in wear loss and capable of meeting various demands of customers.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a preparation method of lightweight wear-resistant rubber materials. Background technique [0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer, its glass transition temperature (Tg) is low, and its molecular weight is often large, greater than hundreds of thousands. The molecular chains of the rubber can be cross-linked. When the cross-linked rubber is deformed by an external force, it has the ability to recover quickly, and has good physical and mechanical properties and chemical stability. Rubber is the basic raw material of the rubber industry and is widely used in the manufacture of tires, hoses, tapes, cables and other rubber pro...
