Embodiment 1
[0061] (1) Preparation of modified sodium silicate
[0062] Add sodium silicate into the reaction tank with a heating device, raise the temperature to 75°C under the condition of 250r / min, adjust the speed to 450r / min, add ethanolamine and K12 to mix well, and adjust the speed to 1000r / min min, keep the temperature at 75°C, slowly add 10% phosphoric acid solution until the pH value is 10.5, react at 250r / min and 75°C for 180min, then pass cold water into the jacket of the reaction tank to reduce the temperature of the liquid in the tank Cool down to 38°C to obtain modified sodium silicate colloid, which is packaged for future use.
