Abstract

The invention discloses a high-strength flame-retardant cable material for power cables and a preparation method thereof. The cable material comprises, by weight, 60-100 parts of heat-vulcanized silicone rubber, 20-100 parts of silicon dioxide, 20-30 parts of white carbon black, 10-15 parts of potassium peroxide, 20-30 parts of magnesium chloride, 6-8 parts of composite ceramic powder, 25-35 parts of water-granulated slag micro powder, 4-6 parts of glass fiber, 8-16 parts of sodium orthosilicate, 30-40 parts of zinc stearate and 20-30 parts of reinforcing agent. While good mechanical performance and insulativity are kept, the overall strength and flame retardancy of the cable material are improved, and the application range of the cable material is widened.

Description

Technical field [0001] The invention relates to the field of cable material production, in particular to a cable material for high-strength flame-retardant power cables and a preparation method thereof. Background technique [0002] At present, the cable materials on the market are not scratch resistant, the overall strength is low, and white marks appear on the cable surface after folding or collision. Because polyolefin has the characteristics of low relative density, chemical resistance, good water resistance, good mechanical strength, electrical insulation, etc., polyolefin compositions that have elasticity while maintaining good thermoplastic properties have been widely used in various fields. For example, it can be used for films, pipes, plates, various molded products, wires and cables, etc. When polyolefin is used in wires and cables, it will increase the hardness of the cable material, which is not suitable for applications that require flexible cables. Summary of the ...
