Abstract

The invention relates to a wire insulation layer composition with scraping resistance, and a preparation method and a wire thereof. The wire insulation layer composition with the scraping resistance comprises the following components in parts by weight: 70-90 parts of polypropylene, 60-80 parts of styrenic thermoplastic elastomers, 50-65 parts of inorganic fillers, 1-5 parts of compatibilizers, 30-35 parts of a halogen fire retardant, 1-3 parts of an internal lubricant, and 1-3 parts of an external lubricant. The wire or the cable, which is prepared from the composition disclosed by the invention, has excellent scraping resistant property, and has tensile property at the same time.

Description

technical field [0001] The invention relates to the technical field of insulating layer materials for wires or cables, in particular to a scratch-resistant wire insulating layer composition, a preparation method thereof, and an electric wire. Background technique [0002] At present, wires and cables have been widely used in the transmission of various 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 base material for various wire and cable coverings. Over the years, soft PVC materials (including various additives such as stabilizers, plasticizers, and fillers) have been used for wires due to their necessary mechanical strength, excellent flexibility, relatively low price, and mature processing technology. The most typical and commonly used resin system for cable covering materials. [00...
