    摘要: A method for preparing an insulating varnish. The method includes: providing equivalence of an epoxy resin solution having a concentration exceeding 99 wt. % and acetone solution having a concentration of 40 wt. %, adding silane coupling agent-modified hexagonal boron nitride (BN) having a particle size of between 200 and 250 nm to the acetone solution and stirring; mixing the epoxy resin solution and the acetone solution and stirring, and dispersing the resulting mixture; adding to the mixture, low molecular weight polyamide resins as a curing agent, and stirring to uniformly disperse the curing agent; adding n-butane as a lubricant to the mixture and stirring, cooling the mixture to room temperature, adding di-n-butyl phthalate as a diluent to the mixture and stirring; and allowing the mixture to stand in a vacuum drier to remove bubbles to yield the insulating varnish, which is free of bubbles.
