High-temperature-resistant polyphenylene sulfide modified cable material and preparation method thereof

Abstract

The invention discloses a high-temperature-resistant polyphenylene sulfide modified cable material and a preparation method thereof. The material is prepared from the following raw materials in parts by weight: 8-12 parts of filler, 0.3-0.8 parts of composite heat stabilizer, 10 parts by weight ‑15 parts of polyvinyl fluoride, 45‑55 parts of polyphenylene sulfide, 0.3‑0.8 parts of coupling agent, 0.1‑0.3 parts of crosslinking agent; the composite thermal stabilizer is added to polyphenylene sulfide and Cross-linking modification under the condition of controlling the degree of polymerization of polyphenylene sulfide significantly improves the high temperature resistance of polyphenylene sulfide, and retains good processability. The polyphenylene sulfide material used in cables can be used Significantly increase the high temperature performance of the cable.

Description

technical field

[0001] The invention relates to the field of cable materials, in particular to a high-temperature-resistant polyphenylene sulfide 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 cab...
