Embodiment Construction

[0011] A low-smoke, halogen-free, flame-retardant polyphenylene ether elastomer cable material, made of the following raw materials in parts by weight (kg):

[0012] Polyphenylene ether 25, ethylene-methyl acrylate copolymer (EMA 1126AC) 34, tantalum boride 7, hafnium diboride 2, boric acid 2, monoglyceride stearate 6, zinc stearate 3, zinc oxide 1, Rapeseed oil 5, aluminum hydroxide powder 15, bauxite 26, glycerol triglyceride 4, methyltrimethoxysilane 3, accelerator DM 2, modified diatomite 8.

[0013] Described modified diatomite is made by following method:

[0014] Put diatomite at 450-500°C for 3-4 hours, take it out, cool it, soak it in 10-12% hydrochloric acid solution for 1-2 hours, take it out, wash it with pure water, dry it and grind it into powder; Add aluminum nitride equivalent to 40% of the weight of diatomite, 3% calcium stearate, 3% zirconium fluoride, and 4% alum powder, mix and grind for 30-40 minutes, and then spray an equivalent amount of diatomite Tria...
