Abstract

The invention discloses a cold resistant polyvinyl chloride cable material and a preparation method, the cable material comprises the following raw materials by weight: 80-90 parts of SG-3 type PVC resin, 15-20 parts of fluorosilicone rubber, 10-15 parts of polytrifluorochloroethylene, 16-22 parts of dioctyl sebacate, 10-15 parts of dibutyl phthalate, 2-3 parts of lead sulfate tribasic, 1-2 parts of dibasic lead phosphate, 0.5-1 part of bisphenol A, 5-10 parts of nano kaolin, 10-15 parts of gas phase white carbon black, 8-12 parts of nano potash feldspar powder, 1-2 parts of zinc oxide, 0.5-1 part of calcium stearate, 1-2 parts of barium stearate, 2-4 parts of liquid paraffin, 12-16 parts of ammonium polyphosphate, 6-9 parts of barium metaborate and 4-6 parts of composite filling material. The cable material has excellent cold resistance, and can be normally used under low temperature of -50 DEG C--65 DEG C, the shock resistance is good, so that the problems of poor cold resistance and poor shock resistance under low temperature condition of the polyvinyl chloride cable material can be solved.

Description

technical field [0001] The invention relates to a polyvinyl chloride cable material and a preparation method thereof, in particular to a cold-resistant polyvinyl chloride cable material and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is widely used as a sheath material for wires and cables due to its flame retardant, oil resistance, corona resistance, chemical corrosion resistance, good water resistance and processability. However, the existing polyvinyl chloride cable materials still have poor cold resistance and low-temperature impact performance, which limits their application in low-temperature and high-cold environments. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the prior art and provide a cold-resistant polyvinyl chloride cable material and a preparation method thereof, whose cold-resistant temperature can reach -65°C below zero. [0004] The technical scheme that...
