Abstract

A high temperature resistant polyvinyl chloride / nitrile rubber composite cable material, the raw material comprises the following components in parts by weight: 100 parts of polyvinyl chloride; 20-50 parts of nitrile rubber; 20-40 parts of plasticizer a; agent b 20-30; flame retardant a 5-10 parts; flame retardant b 5-20 parts, filler a 10-40 parts, filler b 20-30 parts; heat stabilizer 2-10 parts; lubricant 0.5- 2 parts; 0.2-0.8 part of antioxidant a; 0.2-0.8 part of antioxidant b; 0.2-0.8 part of antioxidant c; 1-3 parts of processing modifier. The invention solves the problem of poor heat resistance of the polyvinyl chloride / nitrile-butadiene rubber composite cable material system, and the temperature resistance level is increased from the original 80 DEG C to 105 DEG C. The cable material can be used in household oil-resistant occasions, locomotive cables, High flexibility and high toughness mobile cables such as robot cables.

Description

technical field [0001] The invention belongs to the technical field of cable materials, in particular 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 anti-climate change, waterproof, anti-chemical properties and good electrical insulation properties. Although this material is sensitive to light and heat, the light and heat stability of PVC resin can be improved by adding stabilizer. [0003] With the improvement of the production capacity of PVC resins, plasticizers and industrial additives and the development and application of environmentally friendly products, the application of PVC in wires and cables has made a qualitative leap. With the imp...
