Problems solved by technology

The polyvinyl chloride cable material of the prior art will release a large amount of toxic gas and smog when burned, which is easy to pollute the environment
Polyolefin materials meet the requirements of energy saving and environmental protection, but are still insufficient in flame retardancy and durability. Therefore, in the prior art, inorganic flame retardants are generally added to improve their performance. Due to the problem of capacity, it is easy to cause the decline of the mechanical properties of the material, so it is difficult to obtain products with good comprehensive properties.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a flame-retardant and environment-friendly insulating material used for preparing cables for distribution cabinets. Background technique [0002] In recent years, with the rapid development of electricity, the demand for power distribution cabinets is increasing. The demand for cables as the core components of power distribution cabinets is also increasing day by day, so there is a special need for cable materials with excellent comprehensive performance, energy saving and environmental protection. The polyvinyl chloride cable material in the prior art will release a large amount of toxic gas and smog when burned, which is easy to pollute the environment. Polyolefin materials meet the requirements of energy saving and environmental protection, but they are still insufficient in flame retardancy and durability. Therefore, in the prior art, inorganic flame retardants are generally ...
