Abstract

The invention provides a zero-halogen and low-smoke flame retardant cable material for computers. The cable material is prepared from the following raw materials, by weight, 20-30 parts of polypropylene, 60-80 parts of methyl-vinyl silicone rubber, 10-20 parts of an EVA resin, 8-10 parts of aluminum hydroxide, 0.5-1.0 part of butyl stearate, 1-3 parts of zinc stearate, 8-12 parts of epoxy soybean oil, 4-6 parts of zinc oxide, 0.5-1.0 part of molybdenum trioxide, 30-50 parts of fumed silica, 10-13 parts of modified argil, 0.5-1.0 part of an antioxidant H, 0.1-0.3 parts of an antioxidant AW, 0.5-1.5 parts of a promoter NOBS, 0.2-0.5 parts of a vulcanizing agent DCBP, 8-10 parts of ammonium polyphosphate, 12-15 parts of antimony (III) oxide and 6-8 parts of zinc borate hydrate. The cable material has the advantages of excellent flame retardation, very less smoke in combustion, no generation of toxic gases or corrosive gases, good weather resistance, good abrasion resistance and good insulation property.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a halogen-free low-smoke flame-retardant cable material for computers and a preparation method thereof. Background technique [0002] With the rapid development of the global economy and the enhancement of human awareness of environmental protection, the requirements for the quality and performance of wires and cables in various fields are getting higher and higher, and there are more and more fires caused by the aging of wires and cables. How to reduce the fire Low smoke, halogen-free, flame retardant, and environmental protection have also become the development direction of the wire and cable industry. Among them, the demand for halogen-free low-smoke flame-retardant cable materials is increasing. At present, most of the production of halogen-free low-smoke flame-retardant cable materials is to add a large amount of aluminum hydroxide or magnesium hydroxide to polyolefin subst...
