Cold resistant PVC cable material and preparation method thereof

Abstract

The invention provides a cold resistant PVC cable material. The cold resistant PVC cable material is prepared by using the following raw materials, by weight, 75-80 parts of a PVC resin, 20-25 parts of a vinyl chloride-vinyl acetate copolymer, 1-3 parts of o-hydroxycinnamic acid, 0.2-0.3 parts of zinc oleate, 0.1-0.2 parts of glycerol, 4-6 parts of an MBS resin, 10-15 parts of calcium carbonate powder, 5-10 parts of a modification filler, 0.3-0.8 parts of epoxidized soybean oil, 0.2-0.3 parts of stearic acid, 1.0-2.0 parts of titanium dioxide, 1.0-2 parts of ACR, 10-15 parts of aluminum hypophosphite, 1-2 parts of organic phosphate, 1.0-3.0 parts of PE wax and 1-2 parts of ethyl acrylate. The cable material has a very good low temperature resistance, has a brittle temperature with low temperature impact reaching -50DEG C, has a lower making cost than routine low temperature resistant cable materials, and can resistant a temperature of -50DEG C. The cold resistant PVC cable material can be widely used in low temperature environment and has a low price.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a cold-resistant PVC cable material and a preparation method thereof. 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 flame-retardant cable ...

AI Technical Summary

Problems solved by technology

Among them, the demand for halogen-free low-smoke flame-retardant cable materials is increasing. At present, most of the production of halogen-free low-smoke flame-retardant cable materials is to add a large amount of acetylene carbon black or acetylene carbon black to polyolefin substrates to achieve flame retardancy. Effect, however, the addition of a large amount of inorganic materials affects the physical and mechanical properties and processing of cable materials
