Abstract

The invention relates to an anti-burning conveyor belt, comprising a cover layer rubber, the cover layer rubber is a graphene modified rubber; the raw material components of the graphene modified rubber are as follows in parts by weight: No. 3 smoked sheet rubber 55~ 65 parts, styrene-butadiene rubber SBR-1502 35-45 parts, nano zinc oxide 2.5-3.5 parts, stearic acid 1.3-1.8 parts, antioxidant 4010NA 1-1.5 parts, antioxidant RD 2-2.5 parts, antioxidant MB 1 ~2 parts, 45~55 parts of carbon black N220, 8~10 parts of petroleum resin, 4~5 parts of pine tar, 1.5~2 parts of sulfur, 2~2.5 parts of accelerator CBS, 1~1.5 parts of accelerator TMTD, accelerator 1-1.5 parts of DTDM, 4-8 parts of graphene pre-dispersed EPSBR masterbatch, and 5-10 parts of graphene pre-dispersed natural rubber masterbatch. The graphene-modified rubber in the present invention has excellent mechanical properties and strong anti-burning ability, and is used to manufacture the conveyor belt covering layer, which can significantly improve its service life, and at the same time obtain the ability to carry high-temperature materials.

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 ...
