| titleOfInvention | Process for the synthesis of prehydrolyzed alkyl polysilicates |
| abstract | The invention relates to a two-step synthesis method of prehydrolyzed alkyl polysilicate. In the synthesis method, silica precursor hydrated to 90 to 100% is added to maximize the condensation reaction rate, and silica precursor hydrated to 25 to 70% is additionally added to terminate the condensation reaction, so that the condensation reaction time can be significantly shortened relative to the conventional one-step synthesis method and can be even shortened without using a condensation catalyst, so that catalyst procurement cost and a catalyst separation step may not be required in the process, thereby having a simple process and reducing production cost. In addition, the amount and time point of the additional addition of the silica precursor can be controlled, so that the gelling reaction time and weight average molecular weight are easily controlled, and the pre-hydrolyzed alkyl polysilicate excellent in storage stability and processability is synthesized. |
