Abstract

The invention relates to an insulation material of an electric wire or an electric cable. A halogen-free, anti-scratch, anti-abrasion and fireproof electric wire insulation material is prepared from the following components in percentage by mass: 15 to 25 percent of hydrogenated SEBS (Styrene-Ethylene-Butadiene-Styrene Block Copolymer), 5 to 15 percent of mineral oil, 5 to 15 percent of polypropylene, 5 to 15 percent of metallocene polyethylene, 5 to 10 percent of EPDM (Ethylene-Propylene-Diene Monomer) rubber, 15 to 25 percent of polyphenyl ether, 5 to 15 percent of diethyl aluminum phosphinate, 5 to 15 percent of melamine cyanurate, 1.5 to 2.0 percent of an anti-scratch agent, 0.1 to 0.3 percent of an anti-aging agent and 0.5 to 1.5 percent of a lubricating agent. According to the halogen-free, anti-scratch, anti-abrasion and fireproof electric wire insulation material disclosed by the invention, ceramic microbeads or grafted maleic anhydride is added as the anti-scratch agent, so that the scratch resistance and the abrasion resistance of the halogen-free, anti-scratch, anti-abrasion and fireproof electric wire insulation material are remarkably increased.

Description

technical field [0001] The present invention relates to insulating materials for wires or cables. Background technique [0002] Wires and cables have been widely used in the transmission of various types of energy and signals. Compared with other materials, polymer has the advantages of light specific gravity, easy molding, good comprehensive mechanical properties and excellent electrical insulation properties, and has become the preferred matrix material for the sheath of various wires and cables. At present, the high-quality wire and cable insulation materials on the market are thermoplastic elastomers (TPE). These insulating materials generally have problems such as poor wear resistance and scratch resistance. Contents of the invention [0003] Based on this, the technical problem to be solved by the present invention is to provide a TPE halogen-free scratch-resistant, wear-resistant and fire-resistant wire insulation material. [0004] The technical scheme that the ...
