Abstract

The invention provides a halogen-free flame-retardant polyolefin cable material for an automobile and a preparation method thereof. The halogen-free flame-retardant polyolefin cable material for the automobile comprises the following preparation raw materials in parts by weight: 15-50 parts of an ethylene-vinyl acetate copolymer, 5-15 parts of an ethylene-octylene copolymer, 18-22 parts of a linear low density polyethylene resin, 10-15 parts of a silane grafted ethylene-octylene copolymer, 5-15 parts of a compatilizer, 60-160 parts of a halogen-free flame retardant, 1-10 parts of a flame retardant synergist, 1-3 parts of an assistant cross-linking agent, 0.5-2 parts of a composite antioxidant, 0.5-2 parts of a metal deactivator, 0.5-1 part of a stabilizer, 1-3 parts of a special filler, and 1.5-6 parts of a lubricant. The halogen-free flame-retardant polyolefin cable material for the automobile is excellent in mechanical property and electrical property, can resist high temperature of 150 DEG C, can resist thermal aging for 3000 hours, and is halogen-free, flame-retardant, green and environment-friendly.

Description

technical field [0001] The invention belongs to the field of material chemistry, and relates to a halogen-free flame-retardant polyolefin cable material for automobiles and a preparation method thereof, in particular to a cross-linked halogen-free flame-retardant polyolefin cable material for automobiles with a heat aging resistance of 150 ° C and 3000 hours of radiation and its preparation method. Background technique [0002] As cars become more automated, the number and length of wires running inside them continues to grow. Due to the limitation of narrow space and harsh conditions of use, automobile wires are required to be insulated with thin walls, resistant to fuel oil and lubricating oil, with high wear resistance, high temperature resistance, non-melting when welding wires, flame retardant, etc., radiation crosslinking Polyolefin insulated automotive wires can meet these requirements, especially thin-walled halogen-free flame-retardant cables with small cross-secti...
