Abstract

The invention discloses a tensile-resistant polycarbonate modified cable material and a preparation method thereof. The material is prepared from the following raw materials in parts by weight: 10 to15 parts of basalt fiber, 0.001 to 0.003 part of graphene, 8 to 12 parts of modifying agents, 10 to 15 parts of polyphenylether, 35 to 45 parts of polycarbonate, 0.3 to 0.8 part of coupling agents and0.1 to 0.3 part of crosslinking agents. The basalt fiber subjected to modification treatment is added into polycarbonate and is subjected to cross linking modification; the tensile-resistant intensity energy of the polycarbonate is obviously improved; good processing performance is remained; when the polycarbonate material is used for cable sheath layers, the tensile-resistant performance of thecable can be obviously enhanced.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a tensile polycarbonate modified cable material and a preparation method thereof. Background technique [0002] The cable is made of one or more wires twisted to form a conductor core, and then a corresponding insulating layer is applied to the conductor, and a sealed sheath is formed on the outside. It is mainly composed of a core, an insulating layer, and a shielding layer. and sheath layer. The cable occupies less ground and space; the power supply is safe and reliable, and the possibility of electric shock is small; it is beneficial to improve the power factor of the power system; the operation and maintenance work is simple and convenient; it is beneficial to beautify the city and has many advantages such as confidentiality. It is widely used in life. and all areas of production. The function of the cable sheath layer is to seal and protect the cable from the intrusion of ex...
