Abstract

The invention provides an anti-bite cable protective covering. A shell of the anti-bite cable protective covering is prepared from, by mass, 90-110 parts of polyvinyl chloride resin, 40-60 parts of calcium carbonate, 10-20 parts of o-benzene dioctyl, 11-16 parts of chlorinated paraffin, 2-4 parts of compound stabilizer, 0.4-0.8 part of stearic acid and 3-5 parts of anti-mouse-bite master batch 9074-FT-40. The anti-bite cable protective covering is environmentally friendly and safe in formula, is free of toxin and harms to human bodies and the environment, meets the ecological requirements, and meanwhile well achieves a mouse bite prevention function; the prepared cable protective covering is firm and durable, resistant to aging and higher in flexibility and can better achieve a cable core protecting effect.

Description

technical field [0001] The invention belongs to the field of polymer materials and relates to an outer sheath of an anti-tearing cable. Background technique [0002] Rats are rodents that are widely distributed all over the world and have strong reproductive and vitality. Rats have the habit of biting objects to keep their teeth sharp. Cables laid in the field often break down due to the gnawing of rats. [0003] A common solution currently on the market is to use a complex double-layer structure or other protective structures to prevent rats from biting. However, the complex structure will lead to a great increase in cost, so it is not conducive to commercial application. Contents of the invention [0004] In order to solve the above problems, the present invention provides an anti-bite cable outer sheath, which achieves the goals of safety, environmental protection and effective prevention of rats from biting. [0005] In order to realize the above-mentioned purpose of...
