Abstract

The invention discloses a nano antimicrobial polyethylene material and a preparation method thereof. The nano antimicrobial polyethylene material is prepared from the following components in parts by weight: 80-90 parts of polyethylene, 20-30 parts of polyvinyl acetate resin, 10-12 parts of hydroxypropyl methylcellulose, 5-8 parts of triethylene glycol dimethyl acrylate, 2-6 parts of sodium cocoyl glycinate, 2-4 parts of methyl isothiazolinone, 2-4 parts of trimethyl metasilicate, 1-2 parts of polyoxyethylene sorbitan, 0.5-1 part of diethyl dichlorosilane and 0.2-1.8 parts of antimicrobial agent. The invention also discloses a preparation method of the nano antimicrobial polyethylene material.

Description

technical field [0001] The invention belongs to the field of composite materials, in particular to a nano antibacterial polyethylene material and a preparation method thereof. Background technique [0002] Polyethylene (PE) is polymerized from ethylene monomer. Because of its molecular weight and chain structure, it can be divided into high-density polyethylene, low-density polyethylene and linear low-density polyethylene. Polyethylene is an odorless, non-toxic, waxy polymer material with excellent low temperature resistance, the lowest operating temperature can reach -100~-70°C, good chemical stability, and can withstand most acid and alkali erosion. Polyethylene is mainly used to make films, packaging materials, containers, pipes, monofilaments, wires and cables, daily necessities, televisions, radars and other materials. [0003] The commonly used disinfection methods in the past were high temperature, ozone, ultraviolet radiation, chlorine gas disinfection or steam dis...
