Antibacterial polyethylene cable material unlikely to change color

Abstract

The invention discloses an antibacterial polyethylene cable material unlikely to change color. The antibacterial polyethylene cable material unlikely to change color comprises the following raw materials in parts by weight: 15-25 parts of an ethylene-vinyl acetate copolymer, 10-20 parts of polyvinyl chloride, 30-40 parts of polyethylene, 6-14 parts of apatite, 5-11 parts of barium metaborate, 4-9 parts of barium titanate, 6-12 parts of polyacrylonitrile-based carbon fibers, 2-8 parts of modified clay, 2-4 parts of disproportionated rosin, 2-6 parts of deacetylated chitosan polysaccharide, 2-4 parts of dioctyl terephthalate, 0.8-1.2 parts of microcrystalline wax, 0.8-1.6 parts of dicumyl peroxide, 0.3-0.9 part of p-phenylenediamine, 0.4-0.8 part of dodeceny succinicanhydride, 0.5-1 part of cerium oxide, 0.2-0.24 part of lanthanum oxide, 0.6-1.2 parts of a polyphenol antioxidant 1076 and 1.5-2.5 parts of an antistatic agent.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to an antibacterial non-discoloration polyethylene cable material. Background technique [0002] Polyethylene is the most widely used general-purpose plastic and is widely used in the field of cable materials. Experiments have shown that polyethylene is relatively easy to breed bacteria, and pure polyethylene materials can no longer meet the requirements of cable materials. Silver-based antibacterial agents are the most commonly used antibacterial agents, but there are limitations in their application in polyethylene products: they are prone to oxidative discoloration and the antibacterial ability is reduced; mechanical properties, especially tensile strength and elongation at break, are greatly reduced, which greatly limits their use. Application on cable materials; and organic antibacterial agents also have poor heat resistance, precipitation in easy solvent environment, and tox...

Problems solved by technology

Experiments have shown that polyethylene is easier to breed bacteria, and pure polyethylene materials can no longer meet the requirements of cable materials.

Silver-based antibacterial agents are the most commonly used antibacterial agents, but there are limitations in their application in polyethylene products: they are prone to oxidative discoloration and the antibacterial ability is reduced; mechanical properties, especially tensile strength and elongation at break, are greatly reduced, which greatly limits their use. Application in cable materials; and organic antibacterial agents also have poor heat resistance, precipitation in easy solvent environments, and toxic decomposition products
