Abstract

The invention discloses a low temperature resistant sheathed cable material. The cable material is prepared from the following raw materials in parts by weight: 100 parts of suspension type 2 PVC (polyvinyl chloride) resin, 44-50 parts of DOP (dioctyl phthalate) plasticizer, 8-10 parts of chlorinated paraffin, 4-6 parts of 3Pb0.PbSO4, 1-3 parts of 2Pb0.PbSO3, 0.8-1.5 parts of BaSt, 0.3-0.5 part of HSt, 7-12 parts of dioctyl sebacate, 3-5 parts of pottery clay, 8-15 parts of CaCO3, 3-5 parts of Ba-Ca-Zn compound stabilizer, 4-5 parts of epoxidized soybean oil and 1-2 parts of carbon black. The low temperature resistant sheathed cable material has the beneficial effects that with the PVC resin as the raw material, the cable material is low in price, has good flame retardance and electrical insulativity and is resistant to oil and chemical reagents; the cable material is simple in preparation process and dispenses with large power costly equipment, so that the production cost is low; the cable material can be used in the minus 15 DEG C temperature environment.

Description

technical field [0001] The invention belongs to the technical field of cable processing, and in particular relates to a low temperature resistant sheath type cable material. Background technique [0002] The wire and cable manufacturing industry is second only to the automobile industry in the subdivision of the national machinery industry, and is the industry with the largest output value in the electrical appliance industry. The total output value of my country's wire and cable industry has surpassed that of the United States, becoming the world's largest producer of wire and cable. In recent years, the world's cable products have continued to grow, and the fastest growing is in the Americas. The cable products of North American countries account for 26% of the world's total output. Among them, low-voltage cables and wires for the power industry account for 35% of the total cable products, and others include high-voltage cables, wrapped wires, copper core communication ca...
