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

Abstract

Cable material discloses a functionalized cable material having thermal stability enhanced through compounding graphene oxide and polyimide, wherein the cable material is prepared from the following raw materials in parts by weight: 60-65 parts of a thermoplastic polyurethane elastomer, 35-40 parts of polyvinyl chloride, 0.1-0.12 part of stearic acid, 5-6 parts of calcium benzoate, 0.8-1 part of a mercaptan methyltin heat stabilizer, 0.2-0.3 part of a titanate coupling agent 131, 19-20 parts of epoxy soybean oil, 0.4-0.5 part of barium stearate, 6-7 parts of graphene oxide, 6-7 parts of N,N-dimethylacetamide, 2-3 parts of cyclohexyl isocyanate, 3-4 parts of a polyimide powder, and a proper amount of absolute ethyl alcohol. The composite cable material not only has good toughness and rigidity, but also has good thermal stability and excellent aging resistance; and the service life of the cable material is improved.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a cable material with functionalized graphene oxide compounded with polyimide to enhance thermal stability. 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 resistance and antibacterial pr...
