| titleOfInvention | Preparation method of phenyl silicon resin |
| abstract | The invention discloses a preparation method of phenyl silicon resin, and the preparation method comprises the following steps of: dropping acetone and water mixed hydrolysate to a dimethylbenzene and acetone mixed solvent under an ice-water mixed bath by taking phenyl trichlorosilane and diphenyl dichlorosilane as monomers and adopting an inverse hydrolysis method; after the acetone and water mixed hydrolysate is completely dropped, continuing to react under the ice-water mixed bath till hydrolysis is finished; standing, layering to obtain lower acid water, washing the upper hydrolysate to be neutral by using hot distilled water to obtain a phenyl silicon resin prepolymer; then adding a certain amount of condensation catalysts for condensation reaction; after the reaction is finished, washing the condensation catalysts to be neutral by using the hot distilled water; and then distilling solvent dimethylbenzene under the condition of decompression till no dimethylbenzene is positioned in a system to obtain a phenyl silicon resin product. The phenyl silicon resin prepared through the method disclosed by the invention is a rigid and transparent massive solid, has the advantages of better product uniformity, good high temperature resistance and solubility, and the like; and the method disclosed by the invention has the advantages of simple processing condition, solvent recycling and easiness for industrialized production. |
