Problems solved by technology

[0003] In the existing technology, anti-rodent agents are often added to the cable materials, such as cycloheximide, terpenoid monomers, etc., mostly based on "poisonous killing", which will inevitably cause rodents to die after the wire and cable are bitten. The "both losers" result of being poisoned does not meet the environmental protection requirements, and the rodents will still bite the cable material during the period from ingesting the poison to the attack, which cannot achieve a good rodent-proof effect

The cable material produced by the formula provided by the invention has good rat-proof performance.

Description

technical field [0001] The invention relates to the technical field of communication transmission materials, in particular to a rat-proof polyolefin cable material. Background technique [0002] In modern society, cables can be seen everywhere, such as power cables and overhead cables laid by the power sector. Cables play a very important role in national economy and social activities. With the rapid development of economy, the cable industry has become a major part of our country. second largest industry. Rats are one of the three major hazards that endanger plastic cables and optical cables, and cause many accidents every year. The Shanghai Petrochemical General Plant thermal power plant once had a short circuit caused by a brown house rat entering the high-voltage switch, resulting in a sudden interruption of water, electricity and gas, with a loss of 17 million yuan; the Beijing subway was also bitten by a mouse, causing a parking accident, resulting in a failure. Thou...
