Abstract

The invention relates to a high-temperature-resisting thin-wall cable material as well as a preparation method and application thereof. The cable material is prepared from the following components inparts by weight: 15 to 25 parts of an ethylene-butyl acrylate copolymer A, 5 to 15 parts of an ethylene-butyl acrylate copolymer B, 10 to 15 parts of an ethylene-octene copolymer, 5 to 10 parts of polyethylene, 0.1 to 0.5 part of a lubricant, 0.5 to 2 percent of an antioxidant and 45 to 65 parts of a flame retardant, wherein the melt index of the ethylene-butyl acrylate copolymer A under the conditions of 190 DEG C and 21.6 Kg is 5 to 15 g / 10 min; the melt index of the ethylene-butyl acrylate copolymer B under the conditions of 190 DEG C and 21.6 Kg is 0.1 to 3 g / 10 min. According to the cablematerial provided by the invention, two types of the ethylene-butyl acrylate copolymers with different melt indexes, the ethylene-octene copolymer, the polyethylene, the lubricant, the antioxidant and the flame retardant are reasonably matched and specific weight parts are selected, so that the cable material has good high-temperature-resisting performance; the added flame retardant does not influence the extruding performance of the cable material; after the cable material is rapidly extruded, a rear surface is flat and smooth and the thickness is very 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...
