Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an insulating sheath material for connecting cables inside electrical equipment and a preparation method thereof. Background technique [0002] The internal connecting wires of electrical equipment are also called electronic wires. Electronic wires are indispensable connecting wires in electronic and electrical equipment. The characteristics of the internal connecting wires of electrical equipment generally have the following points: 1. Halogen-free flame retardant performance. The internal connecting wires of electrical equipment not only inhibit the spread and spread of flames, but also do not contain halogens, do not produce harmful and corrosive Inert gas (such as HCl), etc. 2. Mechanical properties. In order to solve the shortcomings of narrow and insufficient installation track space, the insulation layer of the internal connecting wire of the electrical equipment...
