Abstract

A halogen-free flame-retardant cable material is disclosed. The cable material comprises following raw materials by weight: 60-80 parts of LDPE resin, 15-25 parts of EPDM resin, 5-15 parts of EVA resin, 70-90 parts of aluminium hydroxide, and 6-8 parts of red phosphorus. The cable material is excellent in extrusion process property, high in LOI value and good in flame retardant property.

Description

technical field [0001] The invention relates to a cable material, in particular to a halogen-free flame-retardant cable material. 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. Therefore, from a period of time, cable materials have a wide market in m...
