Abstract

The invention relates to a heat-conducting halogen-free flame-retardant polyolefin cable material for an automobile wire and a preparation method thereof. The heat-conducting halogen-free flame-retardant polyolefin cable material is prepared from the following raw materials: 30-50 parts of ethylene-vinyl acetate copolymer; 10 to 25 parts of polysiloxane grafted high density polyethylene; 10 to 15 parts of a fluorine-containing macromolecule grafted linear low density polyethylene copolymer; 5-10 parts of a compatilizer; 60 to 160 parts of a halogen-free flame retardant; 1-10 parts of a flame retardant synergist; 1-3 parts of an assistant cross-linking agent; 0.5 to 2 parts of a composite antioxidant; 0.5 to 2 parts of a metal deactivator; 0.5-1 part of a stabilizer; 5-10 parts of a heat-conducting filler; and 1.5-6 parts of a lubricant. The heat-resistant stability, the chemical stability and the oil resistance of the material are improved; the long-term thermal aging resistance and the illumination resistance of the material are improved; the heat conduction coefficient of the material is improved; the extrusion fluidity of the material and the surface smoothness of an extrudate are improved; the preparation method enables various properties of the material to be more excellent, the process is short, and the efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of wire and cable materials for vehicles and its preparation, in particular to a heat-conducting halogen-free flame-retardant polyolefin cable material for automobile wires, and a preparation method thereof. Background technique [0002] Due to multiple factors such as narrow space and severe use conditions, automotive wires are required to be thin-walled insulation, and they are also required to be resistant to corrosion by fuel oil and lubricating oil, with ideal wear resistance and high temperature resistance. performance, non-melting during wire welding, flame retardant and other technical indicators. Irradiation cross-linked polyolefin insulated wire has good corrosion resistance, good insulation and strong adaptability to the environment with relatively high working temperature, so it is often used as automobile wire, that is, the aforementioned vehicle circuit, especially for automobiles with small cr...
