Abstract

The invention discloses a wear-resistant polyethylene and a preparation method thereof, and relates to the technical field of new materials. In the present invention, chitosan is first used to coat graphene oxide and then aminated to obtain chitosan-modified graphene oxide, and then react with graphene oxide under the action of a catalyst after the cellulose is alkylated , to obtain cellulose-modified graphene oxide, and secondly, sodium lignosulfonate is bridged with 1,6-dibromohexane to obtain modified sodium lignin, and finally, chitosan-modified graphite oxide After mixing cellulose-modified graphene oxide with maleic anhydride-modified polyethylene, adding modified sodium lignin, melt-extruding, and granulating to obtain wear-resistant polyethylene. The wear-resistant polyethylene prepared by the invention has excellent wear-resistant performance when rubbing against metal.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a wear-resistant polyethylene and a preparation method thereof. Background technique [0002] As a synthetic polymer compound, plastic is a material that uses monomer raw materials to polymerize by synthesis or condensation reaction. It is composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. Most plastics have the advantages of light weight, chemical stability, no rust, good impact resistance, and good insulation. Therefore, plastics are widely used in stationery, catering, packaging and other fields. Among them, polyethylene plastic products have a wide range of applications. The disposable products made of polyethylene blown film are waterproof, oil-proof and dust-proof. They are widely used in home kitchen conditioning, clean and hygienic, easy to wear, economical and practical, and acid-resistant. Alkali resi...
