Abstract

The invention discloses an anti-creeping cable material for an automobile wire and a preparation method of the cable material. The cable material is prepared from raw materials in parts by weight as follows: 60-80 parts of polyethylene, 10-20 parts of neopentyl glycol dibenzoate, 15-25 parts of superfine silica whiskers, 4-9 parts of aluminum distearate, 11-22 parts of copper milltailings, 5-10 parts of boric sludge, 10-15 parts of diisodecyl adipate, 8-14 parts of magnesium reducing slag and 7-12 parts of tetrapod-like zinc oxide whiskers. With polyethylene, a metallocene cycloolefin polymer and polyetherimide as base materials, the cable material has high mechanical strength and good high-temperature resistance and fatigue resistance, and the superfine silicon whiskers, atomized magnesium alloy powder and the tetrapod-like zinc oxide whiskers are also added, so that the mechanical performance of the cable material can be improved, and the anti-creeping performance of the cable material is improved. The prepared cable material has the advantages of high mechanical strength, good toughness, good high-temperature resistance and excellent anti-creeping performance.

Description

technical field [0001] The invention relates to a cable material and a preparation method thereof, in particular to a creep-resistant automobile wire and cable material and a preparation method thereof. Background technique [0002] Polyethylene, referred to as PE, is a thermoplastic resin obtained by polymerization of ethylene. It is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the lowest operating temperature can reach -100 ~ -70 ° C), good chemical stability, and can resist most acid and alkali erosion (not resistant to oxidizing properties. acid). It is insoluble in common solvents at room temperature, has low water absorption and excellent electrical insulation, and can be widely used in the production of cable products. With the rapid development of the cable industry, there are increasingly higher requirements for the performance of polyethylene cables. However, the existing polyethylene cable materials for automotive wires still h...
