| titleOfInvention | Method for synthesis of pre-hydrolyzed alkyl polysilicate |
| abstract | The present invention relates to a two-step synthesis method of a pre-hydrolyzed alkyl polysilicate. In the method, a silica precursor hydrated to 90 to 100% is added to maximize a condensation reaction rate, and a silica precursor hydrated to 25 to 70% is additionally added to terminate a condensation reaction, so that a condensation reaction time may be remarkably shortened relative to a conventional one-step synthesis method and may be shortened even without the use of a condensation catalyst, so that the catalyst purchase cost and the catalyst separation step in the process may not be required, thus having a simple process and reducing the production cost. Also, the amount and time point of the silica precursor additionally added may be controlled, thereby easily controlling the gelation reaction time and the weight average molecular weight, and synthesizing the pre-hydrolyzed alkyl polysilicate excellent in storage stability and processabilty. |
