Flame retardant mine cable sheath material

Abstract

The invention discloses a flame retardant mine cable sheath material. The flame retardant mine cable sheath material comprises the following raw materials in parts by weight: 32-47 parts of EVA (ethylene vinyl acetate) resin, 25-35 parts of crosslinked insulated polyethylene, 4-5.5 parts of DCP (di-sec-octyl Phthalate), 1.5-3.5 parts of DBP (dibutyl phthalate), 3-5 parts of zinc oxide, 2-3 parts of triallyl cyanurate, 1.7-2.3 parts of triallyl isocyanurate, 1.5-3 parts of HVA-2, 21-25 parts of channel black, 3-6 parts of aluminium hydroxide, 2-5 parts of magnesium hydroxide, 5-6 parts of boron carbide, 0.5-1.5 parts of triethanolamine, 15-30 parts of calcined pottery clay, 0.5-1.5 parts of anti-aging agent ODA and 1-2.5 parts of anti-aging agent 4010NA, wherein the content of vinyl acetate in the EVA resin is 21-30%. The flame retardant mine cable sheath material is resistant to high temperature, has excellent flame retardance, excellent warping and aging resistance effects and is long in service life.

Description

technical field [0001] The invention relates to the technical field of cable sheath materials for mines, in particular to a flame-retardant mine cable sheath material. Background technique [0002] Since mine cables are mostly used in harsh underground environments, most of them are high-temperature, flammable, and highly corrosive. After several years of rapid development, my country's mine cables have formed a considerable scale, and the production capacity has greatly exceeded this year's forecast demand. At the same time, wire and cable companies are facing the problem of urgently improving the technical content of their products. How to prepare a mine cable with high temperature resistance, flame retardancy and anti-aging performance has become a technical problem that needs to be solved at present. Contents of the invention [0003] The invention provides a flame-retardant mining cable sheath material, which has high temperature resistance, excellent flame-retardant p...
