Abstract

The invention discloses a cable material good in weathering resistance and further retardant in flame. The cable material is prepared from the following raw materials: high density polyethylene, an ethylene-octane copolymer, polyimide, carboxy nitrile rubber, epoxy butyl oleate, ethylene bistearamide, dicumyl peroxide, an accelerant TMTD (Tetramethyl Thiuram Disulfide), an antioxidant, an anti-aging agent, tripropylene glycol diacrylate, di-n-butyl sebacate, triallyl cyanurate, ammonium molybdate, gallium oxide, magnesium hydroxide and bentonite. The invention also discloses a preparation method of the cable material good in weathering resistance and further retardant in flame. The cable material prepared by the preparation method has favorable flame-retardant performance, also has excellent weathering resistance, is long in service life and has a wide market prospect.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a cable material with good weather resistance and flame retardancy and a preparation method thereof. Background technique [0002] Power supply has become an indispensable part of the rapid development of the world economy, and wires and cables, as the carrier of power supply, pervade all walks of life. Although the wire and cable industry is only a supporting industry, it accounts for 1 / 4 of the output value of China's electrical industry. It has a wide range of products and a wide range of applications, and is closely related to all sectors of the national economy. The wire and cable industry is the second largest industry in China after the automobile industry, and the product variety satisfaction rate and domestic market share both exceed 90%. Worldwide, China's wire and cable output has surpassed that of the United States, becoming the world's largest producer of w...
