Abstract

The invention discloses a method for preparing high-temperature-resistant, weather-resistant and flame-retardant cable sheaths. The method includes steps of 1, weighing raw materials according to theweights; 2, smashing basalt fibers, glass fibers and carbon fibers and sieving the basalt fibers, the glass fibers and the carbon fibers by 80-mesh filter sieves to obtain mixed fibers; 3, adding polyvinyl chloride, brominated polystyrene, pottery clay, titanium dioxide, carbon black and the mixed fibers obtained at the step 2 into a milling machine and milling the polyvinyl chloride, the brominated polystyrene, the pottery clay, the titanium dioxide, the carbon black and the mixed fibers for 18 min to obtain mixtures; 4, adding the mixtures obtained at the step 3, antioxidants, ultraviolet absorbents, softening agents, heat stabilizers, vulcanizing agents and coupling agents into a twin-screw extruder, extruding and granulating the mixtures, the antioxidants, the ultraviolet absorbents, the softening agents, the heat stabilizers, the vulcanizing agents and the coupling agents and then carrying out drying to obtain the high-temperature-resistant, weather-resistant and flame-retardant cable sheaths. The method has the advantage that the high-temperature-resistant, weather-resistant and flame-retardant cable sheaths prepared by the aid of the method are good in strength, high-temperature resistance, weather resistance, heat resistance and ageing resistance.

Description

technical field [0001] The invention belongs to cables, and in particular relates to a preparation method of a high temperature and weather resistant cable sheath material. Background technique [0002] Flame retardant wire and cable sheathing materials are mainly divided into halogen-containing flame-retardant fuel, low-halogen flame-retardant fuel and halogen-free flame-retardant fuel. Halogen-containing flame-retardant fuel releases a large amount of smoke and corrosive halide gas when burning. [0003] In the event of a fire, these thick smoke and harmful gases will cause harm to the human body and equipment. With the continuous improvement of international environmental protection requirements, the use of halogen-containing and low-halogen resistance fuels will be restricted or prohibited in most cable applications. In order to achieve the purpose of low smoke, low toxicity and flame retardant, many cable material manufacturers at home and abroad are committed to the d...
