Problems solved by technology

[0003] At present, there are more and more special requirements for insulating varnishes, such as fast curing, dielectric properties and thermal conductivity, etc. Therefore, ordinary insulating impregnating varnishes need to be slow in curing speed and unable to conduct heat, which limits its further application range.

Abstract

The invention discloses quick-drying heat-conduction insulating impregnating varnish. The insulating impregnating varnish is prepared from a component A, a component B and a component C, wherein the mass ratio of the component A to the component B to the component C is 1:(1.1-1.4):(0.5-0.65). The quick-drying heat-conduction insulating impregnating varnish disclosed by the invention not only has good heat conduction performance and insulation performance, but also has a high curing speed, has little volatile matter, and is friendly to the environment. According to the invention, the self-madeunsaturated resin is matched with other raw materials, the process is simple, the process is suitable for continuous paint impregnation, and the working benefit is high.

Description

technical field [0001] The invention relates to the field of insulating varnish, in particular to a quick-drying heat-conducting insulating impregnating varnish and a preparation method thereof. Background technique [0002] Insulating varnish, also known as insulating coatings, is a coating with excellent electrical insulation. It has good electrochemical properties, thermal properties, mechanical properties and chemical properties. It is mostly varnish and colored paint. Insulating varnish is a kind of special varnish in varnish. Insulating varnish is an important insulating material based on high molecular polymer, which can be cured into an insulating film or an insulating whole under certain conditions. [0003] At present, there are more and more special requirements for insulating varnishes, such as fast curing, dielectric properties and thermal conductivity, etc. Therefore, ordinary insulating impregnating varnishes need to be slow in curing speed and unable to con...
