Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high-strength flame-retardant cable insulation material. Background technique [0002] With the development of the economy, the demand for wire and cable is increasing, especially in the fields of high-rise buildings, electronic products, electrical appliances, automobiles, computers and aerospace industry products, the requirements for cable materials are also getting higher and higher. The cable material is generally made of polyvinyl chloride, which has a series of advantages such as good mechanical properties, excellent electrical properties, chemical resistance, cold resistance, and good oil resistance. It is an ideal industrial wire and cable material. However, PVC materials have poor aging resistance and flame retardancy. Chinese Patent Publication No. CN103351556 discloses a flexible polyvinyl chloride wire and cable material, which is composed of the following...
