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.
