Abstract

The invention relates to a polyvinyl chloride cold-resistant cable material and a preparation method thereof. The polyvinyl chloride cold-resistant cable material is prepared from the following ingredients in parts by weight: 80 to 110 parts of polyvinyl chloride resin, 8 to 11 parts of DIDP, 28 to 32 parts of dioctyl sebacate, 1 to 5 parts of tribasic lead sulfate, 1 to 5 parts of dibasic lead phosphite, 0.7 to 1.2 parts of calcium stearate, 1.7 to 1.2 parts of lead stearate, 0.2 to 0.8 part of bisphenol A, 17 to 21 parts of petroleum ester, 8 to 12 parts of chlorinated paraffin and 2 to 7 parts of calcium carbonate. The polyvinyl chloride cold-resistant cable material has the characteristics of wear resistance, flattening difficulty, good insulation performance and the like. The occurrence of natural cracking phenomenon under the cold weather conditions can be avoided. The normal operation of the outdoor construction cable laying can be ensured; the influence of severe weather on theconstruction operation can be reduced.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polyvinyl chloride cold-resistant 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, my country's urban and rural power grid transformation, western development and large-scale upgrading of communication facilities have a huge demand for wire and cable products. However, due to my country's vast geographical area and large temperature differ...
