Graphene wear-resistant PE composite material for carrier roller and preparation method of composite material

Abstract

The invention provides a graphene wear-resistant PE (polyethylene) composite material for a carrier roller. The graphene wear-resistant PE (polyethylene) composite material for a carrier roller is prepared from the following raw materials in parts by weight: 0.5 to 2 parts of graphene, 40 to 65 parts of high-density polyethylene, 5 to 25 parts of alkali-free glass fiber, 10 to 25 parts of ultra-high molecular weight polyethylene, 3 to 8 parts of talcum powder, 1 to 3 parts of adhesive, 1 to 3 parts of grafting agent, 0.1 to 0.5 part of antioxidant, 0.1 to 0.5 part of a light stabilizer; 0.1 to 0.5 part of a lubricant, wherein the total parts are 100. Performance detection is carried out on the prepared graphene wear-resistant PE composite material for the carrier roller, and obtained main performance data are as follows: the basic requirements for manufacturing carrier roller products are as follows: the tensile strength is larger than or equal to 40 MPa, the elongation at break is larger than or equal to 10%, the bending strength is larger than or equal to 53 MPa, the bending modulus is larger than or equal to 2980 MPa, and the relative abrasion loss is smaller than or equal to 170 mm<3>.

Description

technical field [0001] The invention belongs to the technical field of polymer processing, and in particular relates to a graphene wear-resistant PE composite material for idlers and a preparation method thereof. Background technique [0002] Belt conveyors, also known as belt conveyors, are widely used in household appliances, electronics, coal mines, building materials and other fields. The idler roller is an important part of the belt conveyor. It has many types and large quantities, and can support the weight of the conveyor belt and materials. Idler rollers account for 35% of the total cost of a belt conveyor and produce more than 70% of resistance, so the quality of idler rollers is particularly important. It mainly includes steel idlers, ceramic idlers and plastic idlers. [0003] According to current market feedback, there are many defects in the use of steel idlers. First, steel idlers are susceptible to chemical corrosion and have poor wear resistance, resulting ...
