Researchers use hydrolysis and condensation to obtain phenyl silicone resin: phenyltrimethoxysilane, diphenyldimethoxysilane, vinyltrimethoxysilane are used as raw materials, and hydrochloric acid aqueous solution is used as the catalyst, and the hydrolysis condensation reaction is performed at elevated temperature for 6 hours Finally, it was distilled under reduced pressure at 120 ° C for 3 hours. After the transparent silicone resin was obtained at room temperature, a certain amount of hydrogen-containing silicone oil and a Pt catalyst were added to perform the hydrosilylation curing reaction.
