Abstract

The invention relates to a graphene-modified rubber and a preparation method and application thereof. The graphene-modified rubber comprises, by weight, 55-65 parts of smoke sheet rubber No. 3, 35-45parts of styrene-butadiene rubber SBR-1502, 2.5-3.5 parts of nano zinc oxide, 1.3 to 1.8 parts of stearic acid, 1 to 1.5 parts of an antiager 4010NA, 2 to 2.5 parts of an antiager RD, 1 to 2 parts ofan antiager MB, 45 to 55 parts of carbon black N220, 8 to 10 parts of petroleum resin, 4 to 5 parts of pine tar, 1.5 to 2 parts of sulfur, 2 to 2.5 parts of an accelerator CBS, 1 to 1.5 parts of an accelerator TMTD, 1 to 1.5 parts of an accelerator DTDM, 4 to 8 parts of graphene predispersed emulsion polybutadiene rubber master batch and 5 to 10 parts of graphene predispersed natural rubber master batch. The graphene-modified rubber has excellent mechanical properties and strong anti-burning ability, is used for manufacture of a conveyor belt covering layer and can significantly improve the service life.

Description

technical field [0001] The invention relates to rubber technology, in particular to graphene-modified rubber, its preparation method and its application in conveyor belts. Background technique [0002] Rubber (Rubber) is a polymer material that can quickly recover from deformation under large deformation and has high elasticity. 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. Rubber is divided into two kinds of natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and other plants; synthetic rubber is obtained by polymerization of various monomers. Rubber products have been widely used in all aspects of industry or life. In recent ...
