Antibacterial waterproof polyethylene cable material

Abstract

The invention discloses an antibacterial waterproof polyethylene cable material. The antibacterial waterproof polyethylene cable material is prepared from, by weight, 25-35 parts of polyethylene, 5-12 parts of polytrifluorochloroethylene, 10-18 parts of ethylene-vinyl acetate copolymer, 2-10 parts of polyacrylonitrile-based carbon fiber, 2-8 parts of aluminum oxide, 3-8 parts of aluminum borate whiskers, 2-7 parts of sodium antimonite, 0.2-0.6 part of diethylenetriamine, 0.4-0.8 part of cyanoethylated diethylenetriamine, 0.1-0.6 part of p-phenylenediamine, 1-2 parts of chlorinated polyethylene wax, 0.4-0.9 part of dioctyl adipate, 1-4 parts of modified clay, 1-3 parts of chitosan polysaccharide, 1-2 parts of chlorinated paraffin, 0.1-0.16 part of lanthanum oxide, 0.4-0.9 part of cerium oxide, 0.4-0.8 part of stabilizer and 1-2 parts of color master batch. The antibacterial waterproof polyethylene cable material is good in waterproofness and thermal stability, excellent in mechanical performance and antibacterial performance and not prone to oxidation and discoloring.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to an antibacterial and waterproof 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 toxic ...

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
