Abstract

The invention provides a flame-retardant cable sheath and a preparation method thereof and relates to the technical field of cable production. The flame-retardant sheath is prepared from the followingraw materials in parts by weight: 65-75 parts of polyethylene, 35-45 parts of phenolic resin, 15-25 parts of ethylene propylene diene monomer, 16-20 parts of chlordane anhydride, 16-20 parts of citrate, 10-14 parts of magnesium hydrate, 4-8 parts of aluminum hydroxide, 10-14 parts of graphite powder, 4-8 parts of red phosphorus, 2-4 parts of an anti-ageing agent, 2-4 parts of a plasticizer, 2-4 parts of a lubricant, 1-2 parts of a dispersant and 1-2 parts of a defoamer. The flame-retardant cable sheath provided by the invention overcomes the defects in the prior art, improves the flame retardance of the cable sheath effectively, prevents accidents of combustion, even fires, caused by electricity leakage of a worn cable, and is high in safety. The components are matched one another to inhibit combustion of the cable sheath effectively, so that the flame-retardant cable sheath is superior in performance and suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of cable sheath production, in particular to a flame-retardant cable sheath and a preparation method thereof. Background technique [0002] The cable jacket is the outermost layer of the cable. The cable is usually composed of three parts, the cable core material, the insulating sheath and the cable sheath, the outer covering of the cable core material is the insulating sheath, and the outer covering of one or more strands of the insulating sheath is covered with the cable sheath. The mutual cooperation between the insulating sheath and the cable sheath plays an important role in protecting the cable core material. [0003] At present, the formula composition and production process of the cable sheath are unreasonable, which leads to poor flame retardancy of the cable sheath, especially for damaged cables, which are prone to leakage and other accidents, so that it is very easy to burn and cause a fire, and ...
