Summary: | The invention relates to the field of silicon resin preparation, in particular to a preparation method of high-refractive index phenyl silicon resin. The method is characterized by comprising the following steps of: adding water, lithium hydroxide, reactants and cyclohexane into a reaction kettle for hydrolysis reaction; after the reaction, standing and discharging alkaline water; then adding tetramethylammonium hydroxide for polymerization reaction; and after the reaction, washing and desolventizing in vacuum to obtain the product. In the invention, a vinyl reaction group is introduced to the phenyl silicon resin so that the phenyl silicon resin can participate in the solidification addition reaction, and the toughness and strength of the product can be effectively improved. |
