| titleOfInvention | Method for preparing phenyl silicone resin with high-refractive index |
| abstract | The invention discloses a method for preparing phenyl silicone resin with high-refractive index. The method orderly comprises the following steps of (1) by taking silicone-alcohol and alkoxy silane as monomers, carrying out polycondensation under effect of a solid catalyst; (2) filtering out the solid catalyst in obtained reaction liquid after polycondensation is finished, and removing low-boiling-point substance to the reaction liquid to obtain the phenyl silicone resin with high refractive index. Compared with the prior art, the method has the advantages that 1, the method is simple in reaction process condition, easy to control and convenient to industrialize; 2, no solvent is added in the preparation process; and the method is environment-friendly and free of pollution; 3, the reaction process does not need hydrolysis reaction; and the reaction time is short; 4, the catalyst can be directly filtered after the reaction is finished; neutralization is not needed; the catalyst is removed by washing; the process is simplified; and wastewater discharge is also reduced; and 5, the refractive index of the prepared phenyl silicone resin is between 1.56 and 1.60; and the phenyl silicone resin has excellent performances such as high refractive index, high light transmittance, radiation resistance and high and low temperature resistance. |
