Embodiment 1

[0014] A PVC cable material, the raw material components are as follows: 90 parts of PVC resin, 5 parts of basic lead carbonate, 25 parts of diisodecyl phthalate, 15 parts of chlorinated paraffin, 0.8 parts of calcium stearate 1 part, 0.1 part of bisphenol A, 8 parts of clay, and 8 parts of calcium carbonate.

[0015] A preparation method of PVC cable material, the preparation steps are as follows:

[0016] 1) each raw material is weighed by the weight part of composition raw material;

[0017] 2) Put PVC resin into the high-speed mixer, then add diisodecyl phthalate and chlorinated paraffin and stir for a while. After the resin has basically absorbed diisodecyl phthalate and chlorinated paraffin, add basic Lead carbonate, calcium stearate, rely on friction heat to raise the temperature of the material to about 90°C, then add bisphenol A, clay, calcium carbonate, when the temperature of the material rises to 110°C, discharge the material into the cooling mixer and cool down t...

Abstract

The invention discloses a PVC cable material and a preparation method thereof. The raw material components are as follows: 90-110 parts of PVC resin, 5-10 parts of basic lead carbonate, and 25-30 parts of diisodecyl phthalate 15-20 parts of chlorinated paraffin, 0.8-1.5 parts of calcium stearate, 0.1-0.5 parts of bisphenol A, 8-12 parts of pottery clay, and 8-12 parts of calcium carbonate. The PVC cable material of the present invention is made of polyvinyl chloride resin, stabilizer, plasticizer, filler, and antioxidant through batching, high-speed kneading, single-screw extrusion, pelletizing, cooling, screening magnetic separation, metering, and packaging. It has good physical, chemical, electrical, flame retardant and electrical insulation properties.

Description

technical field [0001] The invention relates to the technical field of PVC cable material production, in particular to a PVC cable material and a preparation method thereof. Background technique [0002] Polyvinyl chloride has flame retardancy (flame retardancy value above 40), high chemical resistance (resistance to concentrated hydrochloric acid, sulfuric acid with a concentration of 90%, nitric acid with a concentration of 60% and sodium hydroxide with a concentration of 20%), mechanical strength And the advantages of good electrical insulation. In recent years, my country's cable material production enterprises have made great progress, especially some private enterprises, which have greatly improved in terms of production scale, product structure adjustment and new product development in line with market demand, but PVC cable material Some performances still need to be improved. Contents of the invention [0003] The object of the present invention is to provide a ki...
