Abstract

The invention discloses a light-resistant cable material and a preparation method thereof. The raw material components are: 90-110 parts of PVC resin, 20-25 parts of dioctyl phthalate, and 15 parts of dioctyl sebacate. ‑20 parts, tricresyl phosphate 5‑10 parts, petroleum ester (T‑50) 3‑8 parts, tribasic lead sulfate 1‑3 parts, dibasic lead phosphite 3‑8 parts, dibasic hard 0.1-0.5 parts of lead stearate, 0.5-1 part of barium stearate, 1-2 parts of lead stearate, 0.3-0.7 parts of bisphenol A, 5-10 parts of calcium carbonate. The light-resistant cable material and the preparation method thereof of the present invention are composed of polyvinyl chloride resin, stabilizer, plasticizer, filler, etc. through batching, high-speed kneading, single-screw extrusion, pelletizing, cooling, screening magnetic separation, metering, and packaging. It not only has good electrical and flame retardant protection performance, but also has good light resistance and low production cost.

Description

technical field [0001] The invention relates to the technical field of PVC cable material production, in particular to a light-resistant 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. PVC sheath-grade cable materials have good electrical and flame-retardant protection properties, but PVC sheath-grade cable materials not only have...
