Abstract

The invention discloses a high-strength polyethylene cable jacket material and a preparation method thereof. The high-strength polyethylene cable jacket material is prepared from the following raw materials in parts by weight: 34-52 parts of linear low-density polyethylene, 22-36 parts of polytrimethylene terephthalate, 16-28 parts of polytrifluorochloroethylene, 2-3 parts of 2-cadmium ethylhexoate, 5-10 parts of dipropylene glycol dibenzoate, 15-20 parts of hydrated magnesium silicate superfine powder, 1-2 parts of 3, 5-tert-butyl-4-hydroxy benzoic acid hexadecyl ester, 10-15 parts of pentaerythritol tetra benzoate, 2-3 parts of barium laurate, 4-8 parts of tributyrin, 10-15 parts of potassium titanate whisker, 2-3 parts of 1, 4-dithiothreitol, 1.5-2.5 parts of vitamin C palmitate, 3-5 parts of butyl methoxy dibenzoyl methane, 13-19 parts of fire retardant, 10-15 parts of zirconium dioxide and 1-2 parts of 1,1'sulfo-dis(2-naphthol). The jacket material disclosed by the invention is good in mechanical properties, high in tensile strength, large in elongation at break, tear resistant, abrasion resistant and good in fatigue resistance, temperature tolerance, aging resistance and corrosion resistance, and the jacket material can be used for greatly prolonging the service life of the cable.

Description

technical field [0001] The invention relates to a high-strength polyethylene cable sheath material and a preparation method thereof, belonging to the field of cable materials. Background technique [0002] Polyethylene cable material has the incomparable advantages of PVC cable material, its light weight, good heat resistance, strong load capacity, no melting, chemical corrosion resistance, high mechanical strength, widely used in distribution network, industrial equipment or other large capacity electricity field. However, with the expansion of wire and cable applications, the performance requirements for polyethylene cable sheathing materials continue to increase, and the mechanical strength of general polyethylene cable sheathing materials currently on the market can no longer meet market demand. Contents of the invention [0003] The object of the present invention is to provide a high-strength polyethylene cable sheathing material and a preparation method thereof ...
