Embodiment Construction

[0011] A high cold-resistant insulating cable material, made of the following raw materials in parts by weight (kg):

[0012] EPDM rubber (Germany LANXESS 9650) 14, ethylene-vinyl acetate copolymer (graft rate 8%) 70, wollastonite powder 20, zinc oxide 2, magnesium oxide 2, accelerator DTDM 2, accelerator TMTM 1 , Antiaging agent ODA 2, Dioctyl sebacate 4, Aminopropyltriethoxysilane 3, Methyltriethoxysilane 2, Carbon black N339 20, N660 carbon black 15, Zinc stearate 3, Molybdenum 2, modified diatomite 8.

[0013] Described modified diatomaceous earth 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 amoun...

Abstract

The invention provides a high-cold-resistant insulated cable material and a preparation method thereof. The materials is characterized by comprising the following raw materials by weight parts: 14-19 parts of ethylene propylene diene monomer (German Lanxess 9650), 68-70 parts of ethane-vinyl acetate copolymer, 15-20 parts of wollastonite powder, 2-3 parts of zinc oxide, 1-2 parts of magnesium oxide, 1-2 parts of an accelerator DTDM, 1-2 parts of an accelerator TMTM, 1-2 parts of an antioxidant ODA, 4-6 parts of dioctyl sebacate, 2-3 parts of amino propyl triethoxysilane, 1-2 parts of methyl triethoxysilane, 10-20 parts of carbon black N 339, 5-15 parts of carbon black N 660, 3-4 parts of zinc stearate, 1-2 parts of morpholine, and 6-8 parts of modified diatomite. According to the invention, the dioctyl sebacate is used as a plasticizer to improve cold-resistant performance of the cable material; and the cable material is relatively good in insulating property and high-temperature-resistant performance.
