Abstract

The invention discloses a low-smoke halogen-free flame-retardant polyethylene cable material and a preparation method thereof. The low-smoke halogen-free flame-retardant polyethylene cable material is prepared from the following raw materials in parts by weight: 34-48 parts of medium-density polyethylene, 22-36 parts of polyamide-imide, 5-10 parts of diacetyl epoxy soybean oleic acid glyceride, 4-8 parts of sodium antimonite, 16-28 parts of bisphenol A polycarbonate, 3-4 parts of calcium stearate, 5-10 parts of ammonium metatungstate, 10-15 parts of methyl benzoate, 2-3 parts of zinc ricinoleate, 15-20 parts of StronWiTM powder, 10-15 parts of diphenyl benzyl phosphate, 3-6 parts of magnesium stannate, 1-2 parts of 2,5-di-tert-amyl hydroquinone, 8-12 parts of tris [2-[2-(2-methoxyethoxy)ethoxy]ethyl] orthoborate, 10-15 parts of a flame retardant, 2-3 parts of bi-(2,4-di-t-butylphenyl) pentaerythritol diphosphite and 1.5-2.5 parts of drometrizole trisiloxane. The low-smoke halogen-free flame-retardant polyethylene cable material and the preparation method thereof have the benefits that the cable material has good flame-retardant property, the flame-retardant grade reaches UL94V0, and the cable material is low-smoke halogen-free, cannot release toxic and harmful gas, is safe and environment-friendly and has excellent thermal aging resistance, oil resistance, wear resistance, fatigue resistance and corrosion resistance, thereby having a wide application prospect.

Description

technical field [0001] The invention relates to a low-smoke halogen-free flame-retardant polyethylene cable material and a preparation method thereof, belonging to the field of cable materials. Background technique [0002] Polyethylene cable material has the incomparable advantages of PVC cable material, its light weight, good heat resistance, strong load capacity, no melting, chemical corrosion resistance, high mechanical strength, widely used in distribution network, industrial equipment or other large capacity electricity field. However, with the expansion of wire and cable applications, the performance requirements for polyethylene cable sheathing materials continue to increase, and the flame retardancy of general polyethylene cable sheathing materials currently on the market can no longer meet market demand. Contents of the invention [0003] The object of the present invention is to provide a low-smoke halogen-free flame-retardant polyethylene cable material and...
