Flame-retardant and wear-resistant polypropylene cable material

Abstract

The invention discloses a flame-retardant and wear-resistant polypropylene cable material. The flame-retardant wear-resistant polypropylene cable material comprises the following raw materials in parts by weight: 60 to 80 parts of polypropylene, 30 to 40 parts of modified polyurethane, 20 to 30 parts of carbon black, 15 to 25 parts of lightweight calcium carbonate, 10 to 15 parts of kaolin, 3 to 4 parts of trioctyl acetylcitrate, 1 to 2 parts of epoxidized soybean oil, 20 to 30 parts of microencapsulated red phosphorous, 5 to 10 parts of zinc borate, 1 to 2 parts of 3-aminopropyltriethoxysilane, 1 to 3 parts of dicumyl peroxide, 0.2 to 0.4 part of sulfur, 0.1 to 0.3 part of an accelerator D, 0.3 to 0.5 part of an accelerator CZ, 1 to 2 parts of a Ca / Zn composite stabilizing agent, 1 to 2 parts of a rare-earth stabilizing agent, 1 to 2 parts of dibutyl tin dichloride, 0.2 to 0.3 part of an anti-aging agent MB, 0.1 to 0.3 part of an anti-aging agent RD and 2 to 4 parts of silicone powder. The flame-retardant and wear-resistant polypropylene cable material provided by the invention has good wear resistance and flame retardance and high impact resistance and toughness, and is corrosion-resistant.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a flame-retardant and wear-resistant polypropylene cable material. Background technique [0002] Polypropylene is a thermoplastic resin produced by the polymerization of propylene. Polypropylene has many excellent characteristics, such as: 1. Low relative density, it is one of the lightest varieties in plastics; 2. Good mechanical properties, good molding and processing performance; 3. High heat resistance, continuous use temperature can be Up to 110-120°C; 4. Good chemical properties, almost no water absorption, no reaction with most chemicals; 5. Pure texture, non-toxic; 6. Good electrical insulation; 7. High transparency ratio of polypropylene products Density polyethylene products have good transparency. Therefore, it is widely used in cable materials. However, polypropylene is not wear-resistant, easy to age, easy to burn, and easy to become brittle at low tempera...
