Embodiment Construction

[0013] A kind of cold-resistant PVC cable material, which is prepared from the following component raw materials in weight (kg):

[0014] PVC resin 80, vinyl chloride-vinyl acetate copolymer 25, o-hydroxycinnamic acid 2, zinc oleate 0.3, glycerin 0.1, MBS resin 5, calcium carbonate powder 12, modified filler 8, epoxy soybean oil 0.5, hard Fatty acid 0.2, PE wax 1.0, titanium dioxide 2.0, ACR 1.5, aluminum hypophosphite 12, phosphate 1, ethyl acrylate 2.

[0015] Wherein, the modified filler is prepared by the following method:

[0016] Calcinate the diatomite at 540°C for 3.5 hours, take it out, add 3% sodium hydroxide solution and grind it for 1.5 hours, then add 13% hydrochloric acid solution, adjust the pH value to 4-5, and age for 12 hours. Add sodium hydroxide solution to adjust the pH of the grinding liquid to be neutral, filter and dry to obtain filler powder, then, add camphor essential oil equivalent to 1% of powder weight, 1% nano-carbon, 2% aluminum hypophosphite ...

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 ...
