Abstract

The invention discloses cold-resistant PVC (polyvinyl chloride) cable material. The cold-resistant PVC cable material comprises the following components in parts by weight: 100 parts of PV, 1 to 35 parts of DOS, 0.1 to 10 parts of adipic acid polyester, 1 to 12 parts of tribasic lead sulfate, 0.1 to 5 parts of dibasic lead phosphate, 0.1 to 5 parts of barium stearate, 0.1 to 5 parts of lead stearate, 0.1 to 5 parts of carbon black, 0.1 to 5 parts of antioxidant, and 0.1 to 10 parts of vulcanizing agent; the cold-resistant temperature of the cold resistant PVC cable material is minus 40 to 50 DEG C; in the prior art, the cold resistance is minus 20 DEG C, which is greatly improved; the abrasive resistance is 800 to 1000 circles; the tensile strength is 10 to 30 MPa; the elongation at break is 300 to 450 percent; the heat-resistance temperature is 105 DEG C; and the shore hardness is 85 to 95. The cold resistant PVC cable material has excellent low temperature resistance, ageing resistance, abrasive resistance, heat resistance and insulativity, and can be widely produced to continuously replace existing materials.

Description

technical field [0001] The application belongs to the field of PVC materials, and in particular relates to a cold-resistant PVC cable material and a preparation method thereof. Background technique [0002] With the development of social urbanization, technology, and humanization, and the rapid development of the PVC industry, PVC products are getting closer to the lives of consumers, followed by an increase in the use of PVC materials, and the use of PVC cable materials With the improvement of heat resistance and aging resistance of PVC cable materials, many PVC cable materials focus on the improvement of heat resistance and ignore the optimization of cold resistance in extremely cold regions, and the existing PVC cable materials are easy to be rubbed Damage causes factors such as potential safety hazards or inconvenience, and with the popularization of the concept of humanization and the formation of a new harmonious society, it is very necessary to design a cold-resistant...
