Anti-rat-type PVC cable material and preparation method

Abstract

The invention discloses an anti-rat-type PVC cable material and a preparation method. The material is prepared by the following raw materials by weight: 75 to 95 of XS-2-type PVC, 20 to 30 of metallocene linear low-density PE, 5 to 10 of MBS, 10 to 20 of antimony trioxide , 8 to 12 of brucite powder, 20 to 30 of carbon block N330, 2 to 3 of a calcium zinc composite stabilizer, 0.5 to 1 of stearic acid, 2 to 3 of sulphur, 3 to 5 of zinc oxide, 10 to 15 of nano wollastonite powder, 12 to 18 of epoxidized soybean oil, 10 to 15 of chlorinated paraffin, 8 to 12 of dioctyl sebacate, 5 to 10 of diisodecyl phthalate, 2 to 3 of an anti-rat agent M-17, and 5 to 10 of composite filler. According to the cable material of the invention, excellent anti-rat performance is provided, fire accidents and economic loss caused by rat bite can be effectively prevented, the material is environmental-friendly and safe, the physical and mechanical performance is more reliable, good flame retardant performance is provided, and better low-smoke and low-toxic properties are provided.

Description

technical field [0001] The invention relates to a polyvinyl chloride cable material and a preparation method thereof, in particular to a rodent-proof polyvinyl chloride cable material and a preparation method thereof. Background technique [0002] Rats are one of the three major hazards that endanger PVC sheathed cables and optical cables. The unique smell of PVC makes it a common object for rats to bite. There are often reports of voles biting cables laid in the field and causing cable failure. The failure of wires to bite rats often occurs, resulting in fires caused by short circuits, many accidents, and huge economic losses. Therefore, the market is in urgent need of a cable material product with rodent-proof performance. Contents of the invention [0003] The object of the present invention is to provide a rodent-proof polyvinyl chloride cable material and a preparation method thereof, the cable material has excellent mechanical strength and rodent-proof performance. ...
