Embodiment Construction

[0014] A composite cable material with modified quartz powder to improve oil resistance, prepared from the following raw materials in parts by weight (kg): thermoplastic polyurethane elastomer 60, polyvinyl chloride 35, stearic acid 0.1, calcium benzoate 5, mercaptan Methyl tin heat stabilizer 0.8, titanate coupling agent 1310.2, epoxy soybean oil 19, accelerator TMTD0.6, dimethyl vinyl silicone rubber 5, quartz powder 6, polymethyl vinyl siloxane 1.5 , Proper amount of absolute ethanol.

[0015] The composite cable material for improving the oil resistance of the modified quartz powder is made by the following specific steps:

[0016] (1) Put calcium benzoate into a high-speed mixer, heat to 100°C, add stearic acid and titanate coupling agent 131, stir at 1000 rpm for 20 minutes, and discharge for use;

[0017] (2) Add polyvinyl chloride into the high-speed mixer, add mercaptan methyl tin heat stabilizer, epoxy soybean oil and the material obtained in step (1) successively u...

Abstract

The invention discloses a composite cable material having a modified quartz powder for improving oil resistance, wherein the composite 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, 0.6-0.7 part of an accelerator TMTD, 5-6 parts of dimethyl vinyl silicone rubber, 6-7 parts of a quartz powder, 1.5-2 parts of polymethylvinylsiloxane, and a proper amount of absolute ethyl alcohol. The composite cable material not only has good mechanical properties, but also has good oil resistance; the product is soft and resistant to cracking, can keep original physical properties unchanged in various oil fouling environments, is suitable for manufacturing of oil-submerged pump cables, petroleum industry cables and the like, and has excellent comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a composite cable material in which modified quartz powder improves oil resistance. 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 properties. Thermoplastic...
