High-strength high-flame-resistance cable material and preparation method thereof

Abstract

The invention discloses a high-strength high-flame-resistance cable material. The high-strength high-flame-resistance cable material comprises, by weight, 40 to 60 parts of high-density polyethylene, 30 to 40 parts of phenolic resin, 20 to 30 parts of epoxy resin, 10 to 30 parts of triphenyl phosphate (TPP), 15 to 30 parts of decabromodiphenylethane, 10 to 20 parts of carbon fibers, 5 to 15 parts of calcium stearate, 15 to 25 parts of nanometer aluminum hydroxide, 5 to 10 parts of nanometer calcium carbonate, 2 to 8 parts of nanometer titanium dioxide, 5 to 15 parts of nanometer organosilicon, 3 to 8 parts of antimony oxide, 5 to 15 parts of zinc borate, 4 to 10 parts of calcite powder, 3 to 10 parts of talcum powder, 1 to 5 parts of diatomite, 3 to 8 parts of a fire retardant, 2 to 6 parts of an anti-oxidant, 1 to 5 parts of a plasticizer and 10 to 20 parts of a modified filling material. The cable material prepared in the invention has high strength, good stretching resistance and excellent flame resistance and can meet requirements of the related industry.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a high-strength and high-flame-retardant cable material and a preparation method thereof. Background technique [0002] Plastics for wire and cable insulation and sheathing are commonly known as cable materials, including rubber, plastic, nylon and other varieties. Cable material production enterprises take cable production enterprises as users, as long as there is a demand for wire and cable, there will be a market for cable materials. Except for bare wire products such as steel-cored aluminum stranded wire and electromagnetic wire, almost all wire and cable products require an insulation layer. At present, there are nearly 5,000 wire and cable production enterprises in my country, and there is also a huge demand for wire and cable products for urban and rural power grid transformation, western development, and large-scale upgrading of communication facilities. Therefore, ...

Problems solved by technology

In the prior art, most of the production of low-smoke flame-retardant cable materials is to add a large amount of chlorinated paraffin to the polyolefin substrate to achieve the flame-retardant effect. However, the flame-retardant effect of the cable material prepared by this method is not very good. ideal

In addition, the strength of these cable materials is not ideal enough to provide good protection for the internal wires
