Embodiment Construction

[0011] A polyethylene cable material is made of the following raw materials in parts by weight (kg):

[0012] Linear low density polyethylene 50, PPS 3, monoglyceride stearate 5, nano clay brick slag powder 2, general polystyrene 19, polyisobutylene 3, ABS high rubber powder 2, microcrystalline wax 5, rapeseed oil 4 , sepiolite powder 35, vermiculite powder 23, lapis lazuli powder 14, magnesium oxide 2, zinc oxide 2, zinc stearate 3, accelerator TETD 2, n-butyl methacrylate 3, methyltrimethoxysilane 2, Vinyl triethoxysilane 3, ethyl acrylate 3, high wear-resistant carbon black N330 8, modified diatomaceous earth 8.

[0013] Described modified diatomaceous earth is made by following method:

[0014] Put the diatomite at 460-480°C for 3-4 hours, take it out, cool it, soak it in 10-12% sodium hydroxide solution for 2-3 hours, take it out, wash it with pure water, dry it and grind it into Powder; then add aluminum nitride equivalent to 40% of diatomite weight, 4% ferrocene, 3% z...
