Abstract

The invention relates to a high-temperature-resistant thin-walled cable material and its preparation method and application. The cable material includes the following components in parts by weight: 15-25 parts of ethylene-butyl acrylate copolymer A, ethylene-butyl acrylate copolymer A 5-15 parts of substance B, 10-15 parts of ethylene-octene copolymer, 5-10 parts of polyethylene, 0.1-0.5 parts of lubricant, 0.5-2 parts of antioxidant, 45-65 parts of flame retardant; among them, The melt index of ethylene-butyl acrylate copolymer A at 190°C and 21.6Kg is 5-15g / 10min; the melt index of ethylene-butyl acrylate copolymer B at 190°C and 21.6Kg is 0.1-3g / 10min. The cable material involved in the present invention is reasonably compatible and specific to two kinds of ethylene-butyl acrylate copolymers, ethylene-octene copolymers, polyethylene, lubricants, antioxidants and flame retardants with different melt indices. The selection of parts by weight makes the cable material have good high temperature resistance, and the added flame retardant does not affect the extrusion performance of the cable material, so that the surface of the cable material is smooth and smooth after being extruded quickly, and the thickness is small.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a cable material and its preparation method and application, in particular to a high-temperature-resistant thin-walled cable material and its preparation method and application. Background technique [0002] Low-smoke halogen-free cable materials have received more and more attention in the wire and cable industry because of their environmental protection. In order to achieve better flame retardancy, traditional low-smoke halogen-free cable materials often need to add a large amount of flame retardants, but the improvement of flame retardancy often makes the extrusion performance of cable materials worse, and the extrusion speed is faster or When the cable jacket is thin, the surface tends to be rough and the cable path unstable. At the same time, traditional low-smoke halogen-free cable materials are not resistant to high temperatures, so the processing temperature of t...
