AI Technical Summary

Problems solved by technology

[0002] The traditional manufacturing technology of insulating varnish is mainly made by synthesizing various organic resins through copolymerization or blending and adding curing agent, catalyst diluent, etc., while the silicone resin used in traditional silicone resin insulating varnishes Most of them are solvent-based, so it is inevitable to pollute the environment due to volatile gases during the use of the product, and it needs high temperature curing, which consumes a lot of energy.
However, the few solvent-free silicone resins have the disadvantages of high viscosity, low activity, and high temperature curing.
In general, the organosilicon-based insulating varnishes in the prior art do not meet the requirements of low energy consumption and low pollution
