Abstract

The invention belongs to the technical field of functional polymer materials and insulating material, in particular to a new environment protection ant and rat defending type cable sheathing material and a preparation method thereof. The invention increases the hardness and wear-resisting property of the polyethylene cable sheathing material by adding non-toxic high-efficient intensifier into polyethylene matrix resin, thus achieving the function of the ant and rat defending. Meanwhile, the sheathing material has good mechanical property. The preparation method for the insulating material described by the invention has good controllability, simple technique, and lower cost and has wide application prospect in electrical wire and cable industries.

Description

technical field [0001] The invention belongs to the technical field of functional polymer materials and insulating materials, and in particular relates to an environmentally friendly cable sheath material with low processing cost, ant-proof and mouse-proof functions, and a preparation method thereof. Background technique [0002] Termites have the habit of biting during the foraging process, and rodents also have the habit of constantly grinding their teeth and biting objects randomly. When polyolefin and other plastics are used as the sheath material of wires and cables, they will be affected by rodents and cables in the laying environment. Insects and ants are bitten and damaged, and small holes will appear in the damaged wire and cable sheath layer. When damp or soaked in water, it will cause leakage and short circuit, and even cause explosions and other accidents. In cable fault accidents, the proportion of termite damage accounts for about 60-70% according to survey sta...
