Problems solved by technology

The above insulating materials generally have certain insulating properties, but the mechanical properties, thermal stability and flame retardancy often fail to meet the expected requirements
In order to overcome the above defects, many types and compositions of electrical insulating materials have been prepared in the prior art; for example, Chinese invention patent CN201210277279 discloses a high-strength and high-thermal-conductivity insulating material, which has good thermal conductivity and insulation. However, the mechanical strength of the material is not enough, and the cost is high, so it is not widely used
