Abstract

The present invention discloses a flame-resistant stretching-resistant polyethylene-based electric cable material and a preparation method thereof, wherein the flame-resistant stretching-resistant polyethylene-based electric cable material comprises 14-24 parts of polyethylene, 15-28 parts of a styrene-acrylonitrile copolymer, 3-7 parts of polyphthalamide, 4-10 parts of polyamideimide, 3-9 parts of T151A polyisobutenyl succimide, 6-13 parts of a cis-polybutadiene rubber, 4-8 parts of a KH-792 silane coupling agent, 3-7 parts of tetrabromobisphenol A, 2-6 parts of barium borate, 3-5 parts of molybdenum trioxide, 4-10 parts of barium chloride, and 2-7 parts of magnesium sulfate. The preparation method comprises: stirring in a high speed stirring machine, carrying out extrusion granulation through a twin-screw extruder, plasticizing on an open mill, discharging the sheet, and cooling to obtain the electric cable material. The prepared electric cable material of the present invention has characteristics of high flame resistant strength and high tensile strength.

Description

technical field [0001] The invention belongs to the field of cable materials, and relates to a cable material and a preparation method thereof, in particular to a flame-retardant and stretch-resistant polyethylene-based cable material and a preparation method thereof. Background technique [0002] The structure of wire and cable can be generally divided into four structural components, namely conductors, insulating layers, shielding, and sheaths, or structural elements and components. Commonly used plastics for wires and cables include polyethylene, cross-linked polyethylene, polyvinyl chloride, polypropylene, polyolefin, fluoroplastics, nylon, etc. [0003] Polyethylene is currently the most widely used plastic with the largest amount of consumption. Polyethylene has high resistivity, high breakdown field strength, good weather resistance and manufacturability, and is currently the best electrical insulation material. However, due to its low operating temperature, it is ma...
