Problems solved by technology

[0004] However, this kind of nylon, due to the addition of flame retardants, reduces the surface gloss of the system, that is, increases the diffuse reflection of the system surface and easily absorbs light sources, which accelerates the aging of the system; in addition, the material’s thermal conductivity and heat dissipation performance are not high, and it is easy to accumulate heat. The material is prone to high-temperature aging and lacks oxidation resistance, which affects the service life
