Embodiment 1
[0026]Step 1: Preparation of materials: (1) Preparation of silica sol: 12 parts of tetraethyl silicate, 8 parts of N-(2-aminoethyl)-3-aminopropyltriethoxysilane are added to Dissolve in a reaction kettle containing 35 parts of ethanol; add 1mol / L hydrochloric acid solution to adjust the pH of the reaction solution to 2; set the stirring speed at 150rmp, and the reaction temperature at 80°C for 10 hours, cool to obtain silica sol. (2) Preparation of mixed curing agent: A. under inert gas, diphenylazaborane is added in the reactor containing methylene chloride solution, stirred and dissolved; concentrated sulfuric acid and concentrated nitric acid are added dropwise, and reacted for 4 hours at room temperature; After the reaction, put it into an ice-water bath, extract it with ether, adjust the pH=7 with a saturated aqueous solution of sodium bicarbonate, wash, and dry to obtain dinitrophenazaborane; put it in a reaction kettle, and add Isopropanol, iron powder, concentrated sul...
