Abstract

The object of the invention is to provide a flame-retardant fatigue-resistant cable material and belongs to the technical field of cable manufacture. The flame-retardant fatigue-resistant cable material is prepared from the following raw materials in parts by weight: 50-75 parts of low-density polyethylene (LDPE) resin, 10-20 parts of ethylene propylene diene monomer (EPDM) resin, 5-10 parts of ethylene-vinylacetate copolymer (EVA) resin, 90-110 parts of polyvinyl chloride (PVC) resin, 70-80 parts of aluminum hydroxide, 8-10 parts of red phosphorus, 60-80 parts of dioctyl phthalate, 0.5-1.0 part of erucyl amide, 3-5 parts of zinc stearate and 50-60 parts of heavy calcium carbonate. The flame-retardant fatigue-resistant cable material is excellent in extrusion property, has good flame retardance and good fatigue resistance and is long in service life and easy to produce and manufacture.

Description

technical field [0001] The invention relates to a cable material, in particular to a flame-retardant and fatigue-resistant cable material, which belongs to the technical field of cable manufacturing. Background technique [0002] Plastics for wire and cable insulation and sheathing are commonly known as cable materials, including rubber, plastic, nylon and other varieties. Cable material production enterprises take cable production enterprises as users, as long as there is a demand for wire and cable, there will be a market for cable materials. Except for bare wire products such as steel-cored aluminum stranded wire and electromagnetic wire, almost all wire and cable products require an insulation layer. At present, there are nearly 5,000 wire and cable production enterprises in my country, and there is also a huge demand for wire and cable products for urban and rural power grid transformation, western development, and large-scale upgrading of communication facilities.
