Introduction of modified polyester enamelled wire paint

A modified polyester enamelled wire paint belongs to the field of insulating coatings.

Enamelled wire is an important electrical insulating material, which is prepared by coating high polymer insulating paint on copper, aluminum, manganin alloy and other metal wires according to a specific production process. This specific insulating paint is enamelled wire paint. Enamelled wire can produce a good insulation layer between wires in the winding, so as to improve and stabilize the performance of enamelled wire.

Polyester enamelled wire paint has good mechanical properties, good storage stability, wide source of raw materials and low production cost. However, its heat resistance is poor, and softening and leakage will occur at high temperature. Therefore, it is mainly used in the production of ordinary heat-resistant enamelled wire. In order to improve the heat resistance of polyester enamelled wire paint, research institutions at home and abroad have carried out a lot of modification research on polyester paint, but it has not been widely popularized and applied due to factors such as production cost and production technology.
