Abstract

The invention discloses a polypropylene / liquid crystal elastomer / fullerene composite cable material and a preparation method thereof. The cable material is prepared from the following raw materials in parts by weight: 36 to 47 parts of polypropylene, 22 to 34 parts of liquid crystal elastomer, 18 to 31 parts of fullerene, 6 to 12 parts of white oil, 10 to 15 parts of diisononyl phthalate, 15 to 20 parts of silica fume, 5 to 10 parts of pyrolusite powder, 10 to 15 parts of power plant slag, 2 to 3 parts of calcium stearate, 1 to 2 parts of zinc stearate, 8 to 10 parts of polytetrafluoroethylene micropowder wax, 5 to 7 parts of dichloroethyl aluminum, 10 to 15 parts of triisooctyl borate, 10 to 15 parts of heavy calcium carbonate powder, and 17 to 23 parts of andalusite. The prepared cable material has an excellent comprehensive property, the mechanical properties are excellent, the heat stability is high, the light aging resistant performance is strong, and the weatherability is good.

Description

technical field [0001] The invention relates to a polypropylene / liquid crystal elastomer / fullerene composite cable material and a preparation method thereof, belonging to the technical field of cable material manufacturing. Background technique [0002] In addition to polyvinyl chloride, polyolefins are used in the largest amount of polymer materials for cables, among which polyethylene and polypropylene are the most commonly used. Polypropylene is a thermoplastic resin obtained by polymerization of propylene as a monomer. It has high melting point, heat resistance, corrosion resistance, higher heat distortion temperature and greater hardness than polyethylene. Therefore, polypropylene can be widely used Used to make cable products. In recent years, with the rapid development of the cable manufacturing industry, the requirements for the performance of polypropylene cable materials are getting higher and higher, and the comprehensive performance of traditional polypropylene ...
