Cold-resistant halogen-free cable material for electric automobile

Abstract

The invention relates to a cold-resistant halogen-free cable material for an electric automobile. The cold-resistant halogen-free cable material is prepared from the following raw materials in percentage by weight: 40 to 50 percent of linear low density polyethylene, 0.1 to 1 percent of molybdenum sesquioxide, 0.1 to 3 percent of sodium methyl silicate, 0.1 to 3 percent of aluminium dihydrogen phosphate, 0.1 to 3 percent of isocyanate and 40 to 60 percent of tributyl citrate. The cold-resistant halogen-free cable material for the electric automobile has the characteristics that the extrusion performance is excellent; the halogen-free and environmental-friendly effects are achieved; the cold-resistant performance and the anti-fatigue performance are good.

Description

technical field [0001] The invention belongs to the technical field of material science, and in particular relates to a cold-resistant halogen-free cable material for electric vehicles. 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...
