Problems solved by technology

Among them, the demand for halogen-free low-smoke cold-resistant and flame-retardant PVC cable materials is increasing. At present, the production of halogen-free low-smoke cold-resistant and flame-retardant PVC cable materials is mostly to add a large amount of acetylene carbon black or acetylene to the polyolefin substrate. However, the addition of a large amount of inorganic materials affects the physical and mechanical properties and processing of cable materials.

Abstract

The invention provides a cold-resistant flame retardant grade PVC (Polyvinyl Chloride) cable material which is prepared from the following raw materials in parts by weight: 40-50 parts of a PVC resin SG-2, 30-50 parts of a PVC resin SG-3, 18-22 parts of citric acid tributyl ester, 5-8 parts of triethylene glycol di-isocaprylic acid ester, 8-10 parts of dioctyl adipate DOA, 1-2 parts of chlorinated paraffin, 2-3 parts of a calcium-zinc stabilizer, 1-2 parts of calaium strarate, 8-10 parts of antimonous oxide, 4-6 parts of zinc borate, 3-4 parts of decabromodiphenylethane, 12-15 parts of active CaCO3, 1-2 parts of dicumyl peroxide DCP and 20-25 parts of a modified filler. A cable made of the cable material provided by the invention is good in mechanical property, good in aging property, resistant in low temperature and good in flame retardant property.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a cold-resistant and flame-retardant grade PVC cable material. Background technique [0002] Wire and cable are indispensable and important materials in industrial and agricultural production and modern life. my country is the world's largest producer of wire and cable. The wire and cable industry occupies a very important position in my country's national economy. However, at present, the market The cable material is not resistant to high temperature and aging, and the material turns yellow and becomes brittle after the aging test. There are more and more fires caused by aging wires. How to reduce the incidence of fire and the death rate in the event of fire, low smoke, halogen-free, flame retardant, and environmental protection have also become the development direction of the wire and cable industry. Among them, the demand for halogen-free low-smoke cold-resistant and flame-reta...
