Abstract

The invention discloses a high-strength cable material for power cables and a preparation method thereof. The cable material comprises, by weight, 38-45 parts of TPE resin, 12.5-15.5 parts of PBT resin, 6-8 parts of diethylene glycol dibenzoate, 8-10 parts of triethanolamine, 3.5-4.5 parts of potassium peroxide, 5-8 parts of magnesium chloride, 1.5-3 parts of modified wood ash, 2.5-3.5 parts of water-granulated slag micro powder, 4-6 parts of glass fiber, 0.8-1.6 parts of sodium orthosilicate, 3.4-4.6 parts of zinc stearate and 4.5-6.5 parts of reinforcing agent. While good mechanical performance and insulativity are kept, the overall strength of the cable material is 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 power cables and a preparation method thereof. Background technique [0002] At present, the cable materials on the market are not resistant to scratches, the overall strength is low, and white marks appear on the surface of the cable 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 with elasticity and good thermoplastic properties have been widely used in various fields. For example, it can be used in films, pipes, plates, various shaped products, wires and cables, etc. When polyolefins are used in wires and cables, the hardness of the cable material will increase, and it is not suitable for occasions where soft cables are required.
