Abstract

The invention discloses a high-elasticity high-toughness polypropylene cable material for communication and a preparation method thereof. The high-elasticity high-toughness polypropylene cable material for communication is prepared from the following raw materials in parts by weight: 70-90 parts of atactic polypropylene, 25-35 parts of thermoplastic elastomer SEEPS, 14-26 parts of butanediol cycloterephthalate, 15-25 parts of nano cellulose whisker, 12-20 parts of coumarone indene resin, 6-12 parts of hydroxyl aluminum distearate, 20-30 parts of siliceous shale, 16-24 parts of diisodecyl phthalate, 18-32 parts of asbestos tailing, 2-4 parts of cadmium stearate, 10-15 parts of flocking powder, 9-16 parts of basic magnesium sulfate whisker and 15-25 parts of volcanic ash. The toughness and elasticity of the material are improved; by adding the nano cellulose whisker, flocking powder, basic magnesium sulfate whisker and other raw materials into the system, the tensile strength and elongation at break of the material are enhanced; and the heat resistance, wear resistance and corrosion resistance of the material can also be improved.

Description

technical field [0001] The invention relates to a high-elasticity and high-toughness communication polypropylene 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 elasticity and toughness of polypropylene cable materials for communication are getting higher and higher, and the elasticity and tough...
