Abstract

The invention discloses a pure epoxy powder coating for electromagnetic wire coating, which comprises the following components in proportion by weight: 200 parts of epoxy resin, 3-6 parts of curing agent, 1-5 parts of auxiliary agent, 0-0 parts of filler 20 parts, 0‑10 parts of pigment. The invention also discloses a preparation method of the powder coating. The cured coating of the powder coating has good flexibility and electrical properties, and also has good insulation properties.

Description

technical field [0001] The invention relates to a pure epoxy powder coating for electromagnetic wire coating, and at the same time, the invention also relates to a preparation method of the powder coating. Background technique [0002] Powder coating is a kind of environment-friendly industrial coating, which has many advantages such as energy saving, resource saving, high efficiency and high performance. It has developed rapidly since entering the 21st century and has been widely used in various fields. [0003] In the field of electromechanical products, the quality of insulating materials is a key factor in determining the quality of motor products. Therefore, in order to ensure the normal operation of the equipment, it is necessary to have high-performance insulating materials to improve the adaptability and service life of the equipment to the working environment. In a motor component, the main parts that need insulation coating are the rotor, stator and the magnet wir...
