Abstract

The invention discloses a polyvinyl chloride cable material resistant to heat and shock. The polyvinyl chloride cable material resistant to heat and shock is prepared from polyvinyl chloride, polyurethane, bisphenol-A polycarbonate, poly (tetramethylene succinate), di (2-ethylbutanoic acid) triuret gylcol ester, 2-ethylhexyl epoxystearate, montmorillonite, ammonium heptamolybdate, kaolin, aluminum hydroxide, magnesium hydroxide whisker, antioxidant, 1-azyl-4-methyl piperazine, tri methylol propane tri methacrylate, bisferrocene-base acetylene and a heat stabilizer. The heat stabilizer is prepared through mixing of rhenium complex, cerous carbonate, tribasic lead sulfate, bisphenol A diglycidyl ether, epoxy butyl stearate, lanthanum stearate, glyzinc, aceticacid,2,2',2''-[(octylstannylidyne)tris(thio)]tris-,triisooctylester, mannitol and 2,5-diphenyl-1,3,4-oxadiazole. The polyvinyl chloride cable material has high strength, heat resistance and shock resistance, is resistant to bending and torsion, and has a long service life.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a heat-resistant and shock-resistant polyvinyl chloride cable material. Background technique [0002] With the rapid development of the global economy, the requirements for the quality and performance of wires and cables in various fields are getting higher and higher. Polyvinyl chloride is widely used in wires and cables due to its flame retardant, oil resistance, corona resistance, chemical corrosion resistance, good water resistance and processability. However, polyvinyl chloride has the defects of high brittleness and poor impact resistance, and its thermal stability is not very ideal, which limits the use of polyvinyl chloride cable materials and makes it have the defect of short service life in the process of use. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a heat-resistant and sh...
