Problems solved by technology

[0004] Solvent impregnated varnish: Solvent impregnated varnish (solid content 40% to 70%) has the advantages of convenient use, good impregnation, less loss during heating and baking, stable storage, and low price; the disadvantage is that the impregnation and baking time is long (paint film The drying time is about 0.5 ~ 3h), the solvent is flammable and unsafe, and causes air and environmental pollution, etc.; less solvent impregnation paint (solid content > 70%) can overcome some of its shortcomings to a certain extent

Abstract

The invention relates to solvent-free nuclear motor coil impregnating varnish. The impregnating varnish is mainly prepared by the following raw materials, by weight, 5-15% of liquid vinyl MQ silicon resin, 10-15% of liquid vinyl silicon rubber, 15-30% of phenyl MQ silicon resin and 20-30% of phenyl silicon rubber. Viscosity of the impregnating varnish which is liquid is 200-5000Pa.S. In addition, the solvent-free nuclear motor coil impregnating varnish has excellent heat resistance, mechanical performance and storage stability.

Description

technical field [0001] The invention relates to a solvent-free nuclear power coil dipping varnish and a preparation method thereof. Background technique [0002] Impregnation varnish is used for impregnation treatment of motors and electrical coils, filling gaps and micropores in the insulation system, forming a continuous paint film on the surface of the impregnated object, and bonding the coils into a solid whole, effectively improving the integrity of the insulation system Properties of resistance, thermal conductivity, moisture resistance, dielectric strength and mechanical strength. [0003] Dip varnishes are divided into two categories: solvent-based and solvent-free varnishes: [0004] Solvent impregnated varnish: Solvent impregnated varnish (solid content 40% to 70%) has the advantages of convenient use, good impregnation, less loss during heating and baking, stable storage, and low price; the disadvantage is that the impregnation and baking time is long (paint film...
