High-thermal-conductivity insulation winding belts and preparation method thereof

The invention relates to high-thermal-conductivity insulation winding belts. The high-thermal-conductivity insulation winding belts include single-surface type, double-surface type and three-in-one type high-thermal-conductivity insulation winding belts and are formed by high-thermal-conductivity mica powder paper layers, reinforced material layers and high-thermal-conductivity composite insulation glue layers through composite pressing, wherein a reinforced material adopts alkali-free glass fibers, alkali-free glass cloth and a film; high-thermal-conductivity mica powder paper is prepared from materials in parts by weight as follows: 70-75 parts of mica flakes and 20-30 parts of aluminum nitride. The high-thermal-conductivity insulation winding belts prepared with the method are insulated, have good thermal conducting and heat transferring performance and the characteristics of avoidance of layering and inverted sticking, high flexibility at the room temperature and the like, are easy to wind, eliminate flyi
