Rat and termite resistant cable material

Abstract

The invention relates to the field of cables and discloses a rat and termite resistant cable material which is prepared from the following components in parts by weight: 60-80 parts of high density polyethylene, 40-60 parts of ethylene-vinyl acetate copolymer, 10-12 parts of polyethylene grafted maleic anhydride copolymer, 10-15 parts of white carbon black, 10-20 parts of plasticizer, 10-20 partsof fire retardant, 5-7 parts of stabilizer, 15-25 parts of rat and termite resistant agent and 1-3 parts of antioxidant. By adding the rat and termite resistant agent and compounding several plant extracts for expelling rats, killing termites and the like, through common effect of various principles of odour, toxicity and the like, the rat and termite resistant cable material is more comprehensivein preventing the rats and the termites and is better in effect; and meanwhile, by regulating other components and a ratio thereof of the cable material, the performance of the cable material is notlowered, and the rat and termite resistant cable material is simple in preparation technology, good in effect of a product and suitable for practical production application.

Description

technical field [0001] The invention relates to the field of cables, in particular to a rodent-proof and termite-proof cable material. Background technique [0002] Plastics for wire and cable insulation and sheathing are commonly known as cable materials, including rubber, plastic, nylon and other varieties. Cable material production enterprises take cable production enterprises as users, as long as there is a demand for wire and cable, there will be a market for cable materials. Except for bare wire products such as steel cored aluminum stranded wire and electromagnetic wire, almost all wire and cable products need insulation layer openings, which have broad market development prospects. [0003] But the peculiar smell of plastic makes it a frequent gnawing object for rodents or termites. Regardless of whether it is wild mice or termites in human-active areas, they have a strong ability to damage wire and cable sheaths or insulation layers. It is often reported that vole...

[0003] But the characteristic smell of plastic makes it a frequent gnawing object for rodents or termites

Regardless of whether it is wild mice or termites in human activity areas, they have a strong ability to damage wire and cable sheaths or insulation layers. It is often reported that voles or termites bite cables laid in the wild and cause cable failures, and urban houses It happens from time to time that wires are bitten by rats or termites, so the market urgently needs cable materials with anti-rat and termite properties. At present, ordinary PVC cable materials do not have anti-rodent properties.
