Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a tear-resistant flame-retardant cable material and a preparation method thereof. Background technique [0002] With the development of my country's modern industry, cables are used in all aspects of the national economy and people's lives, but when the cable materials are burned, they will release a large amount of toxic smoke and corrosive gases that endanger the environment and the safety of life and property. With the frequent occurrence of electrical fire accidents Combustion cables came into being. At present, most of the production of flame-retardant cable materials is to add a large amount of inorganic materials to the polyolefin base material to achieve the flame-retardant effect. However, the addition of a large amount of inorganic materials affects the mechanical properties of the cable materials, making them tough and impact-resistant. Lower, easy to tear. ...
