Abstract

A high-temperature-resistant polyvinyl chloride/nitrile rubber composite cable material comprises the following components in parts by weight: 100 parts of polyvinyl chloride, 20-50 parts of nitrile rubber, 20-40 parts of a plasticizer a, 20-30 parts of a plasticizer b, 5-10 parts of a flame retardant a, 5-20 parts of a flame retardant b, 10-40 parts of a filler a, 20-30 parts of a filler b, 2-10parts of a heat stabilizer, 0.5 to 2 parts of a lubricant, 0.2 to 0.8 part of an antioxidant a, 0.2 to 0.8 part of an antioxidant b, 0.2 to 0.8 part of an antioxidant c, and 1-3 parts of a processingmodifier. According to the invention, the problem of poor heat resistance of a polyvinyl chloride/nitrile rubber composite cable material system is solved, the temperature resistance grade is improvedto 105 DEG C from the original 80 DEG C, and the cable material can be applied to high-flexibility and high-toughness mobile cables such as household oil-resistant occasions, locomotive cables, robotcables and the like.

Description

technical field [0001] The invention belongs to the technical field of cable materials, and in particular relates to a high-temperature-resistant polyvinyl chloride / nitrile rubber composite cable material. The cable material can be widely used in the wire and cable industry as a soft wire insulation material and sheath material. Background technique [0002] Polyvinyl chloride (PVC) is a halogen-containing polymer material. Pure PVC granular material has high mechanical strength, very good weather resistance, water resistance, chemical resistance and good electrical insulation properties. Although this material is sensitive to light and heat, the stability of PVC resin against light and heat can be improved by adding a stabilizer. [0003] With the improvement of the production capacity of PVC resin, plasticizer and industrial additives and the development and application of environmentally friendly products, the application of PVC in wire and cable has made a qualitative l...
