Problems solved by technology

However, the polarity of the polyvinyl chloride molecular chain is strong, and it shows a certain degree of brittleness to the outside, which limits the application of polyvinyl chloride.
Existing PVC cables have the defects of high brittleness, poor impact resistance and poor aging resistance, which cannot meet the requirements of the society and need further research and improvement

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high-toughness and aging-resistant modified polyvinyl chloride insulated cable material. Background technique [0002] Polyvinyl chloride is cheap and has a wide range of raw materials. It has the advantages of flame retardant, wear resistance, chemical corrosion resistance, excellent electrical insulation performance and high mechanical strength. It has a wide range of applications in industry, agriculture, construction, daily necessities, packaging and electricity. However, the polarity of the polyvinyl chloride molecular chain is strong, and it shows a certain degree of brittleness to the outside, which limits the application of polyvinyl chloride. Existing PVC cables have the defects of high brittleness, poor impact resistance and poor aging resistance, which cannot meet the requirements of the society and need further research and improvement.
