Antistatic and synergistic cable material with modified graphite cooperated with sodium dodecyl benzene sulfonate

Abstract

The invention discloses an antistatic and synergistic cable material with modified graphite cooperated with sodium dodecyl benzene sulfonate. The antistatic and synergistic cable material is prepared from the following raw materials in parts by weight: 60 to 65 parts of a thermoplastic polyurethane elastomer, 35 to 40 parts of polyvinyl chloride, 0.1 to 0.12 part of stearic acid, 5 to 6 parts of calcium benzoate, 0.8 to 1 part of a methyltin mercaptide thermal stabilizer, 0.2 to 0.3 part of a titanate coupling agent 1310, 19 to 20 parts of epoxidized soybean oil, 2 to 3 parts of an antioxidant 1010, 0.8 to 1 part of sodium dodecyl benzene sulfonate, a proper amount of dimethyl sulfoxide, 4 to 5 parts of graphite oxide and 0.5 to 0.6 part of hydrazine hydrate. The composite cable material has the advantages of the thermoplastic polyurethane elastomer and the polyvinyl chloride, is high in antistatic property and bending strength, and can be used for preparing a coal mine cable; the potential safety hazard is reduced.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a cable material in which modified graphite cooperates with sodium dodecylbenzene sulfonate for antistatic and synergistic effects. Background technique [0002] Polyvinyl chloride (PVC) is characterized by high withstand voltage and insulation resistance, and has properties such as flame retardancy, oil resistance, weather resistance, and chemical resistance, but its dielectric constant and dielectric loss are large, and its cold resistance is poor. Plastic has the characteristics of low price, large usage, and excellent performance in all aspects. It is mainly used in insulation, semi-conductive shielding and sheathing of various wires and cables for wires and cables below 1kV and local communication cables. Thermoplastic polyurethane elastomers have the characteristics of plastic reprocessing and rubber elasticity, and are excellent in cold resistance, abrasion resista...

Problems solved by technology

Although the thermoplastic polyurethane elastomer improves the toughness of the polyvinyl chloride material, it also reduces the modulus of the composite material at the same time, and uses dioctyl phthalate as a plasticizer, and the benzene ring structure contained in it is harmful to the human body. Potentially physiologically toxic and cause environmental pollution
