Motor anti-corrosion coating and motor anti-corrosion method

Abstract

The invention discloses a motor anti-corrosion coating, the anti-corrosion coating is applied on a motor stator and end caps mounted at both sides of the motor stator. The anti-corrosion coating comprises a basic layer and a surface layer from the inside to outside, the basic layer is directly sprayed on the motor stator and the end caps, and the surface layer is sprayed on the basic layer; the basic layer is prepared from the following components (in parts by weight): 40 to 50 parts of acrylic acid / epoxy resin primer; 5 to 8 parts of nano-sized TiO2 particles, 5 to 8 parts of zinc oxide nano particles, 5 to 15 parts of aluminosilicate-based glass beads; 1 to 5 parts of xylene; the surface layer is prepared from the following components (in parts by weight): 90 to 95 parts of silicone polyurethane resin paint / vinyl perchloride anticorrosion varnish; 5 to 10 parts of acrylic acid / epoxy resin primer; 1 to 6 parts of silica sol; 1 to 3 parts of cobalt nitrate; 1 to 3 parts of cerous nitrate.

Description

Technical field [0001] The invention involves a motor anti -corrosion coating and the method of electrical corrosion, which is the field of motor technology. Background technique [0002] The motor is widely used, but the working environment of the motor is generally bad. The main manifestations are: 1. The temperature difference between the working environment is large. For example, in the northern part of China, the minimum outdoor temperature can reach -40 ° C.When it reaches 50 ° C ~ 60 ° C, the temperature is too high, resulting in the motor that is easy to burn, and the temperature difference is large, resulting in a decline in insulation performance due to large environmental changes at the end of the motor coil.The operation of the beach is limited by the working environment. The surrounding is in a corrosive atmosphere. It has a greater impact on all components of the motor and directly affects its service life.It is easy to change sharply and inferior to contact resista...

AI Technical Summary

Problems solved by technology

The existing motor stator is made of insulating varnish and epoxy resin. Due to the unsatisfactory effect of dipping and drying the motor stator winding, the insulation and anti-corrosion performance of the motor and its service life are greatly affected.
