Embodiment 1
[0029] First, add ceramic powder into the reaction vat, then add 93% ethanol aqueous solution, add a pH regulator to adjust the pH value at 5-6, then add tetraethoxysilane and vinylmagnesium bromide, and add 100 ℃ water bath heating and magnetic stirring for 3 hours, after the reaction, the product was washed, dried and filtered to obtain the first product, and then the first product was stirred in the stirring tank for more than 2.5 hours, and then it was ground by rubber mill and entered into the cross-linking tank 7~ After 8 hours, modified ceramic powder was obtained; then, polyimide and chlorosilane were mixed in a ratio of 3:1, heated and stirred until the temperature reached 120°C, and an emulsifier was added to form the first component, and then added to Add sodium bicarbonate to the first component and mix evenly, and finally introduce the mixed solution into the silica sol, mix and cool to obtain a modified polyimide; then, take raw materials by weight, raw materials ...
