Hydrophobic and oleophobic liquid hardening agent and preparation method thereof
The invention belongs to the technical field of building construction materials, and discloses a hydrophobic and oleophobic liquid hardening agent and a preparation method thereof. The preparation method comprises the following steps: at 40-70 DEG C, adding an active silicon powder aqueous solution into an organic-inorganic composite alkali aqueous solution, and stirring for reaction; filtering to obtain colorless transparent liquid A; adding an alcohol substance into the fluoroalkyl acrylate copolymer in a first stirring state, and controlling the pH value to be 7-9; adding a silane coupling agent into the obtained solution while stirring to obtain a mixed solution B; adding potassium methyl silicate into the colorless transparent liquid A at room temperature in a second stirring state, and stirring for reaction; then, adding a lithium silicate solution, and stirring for reaction; and finally, adding the mixed solution B, stirring and reacting until the solution is in a transparent state, thereby obtaining the hydrophobic and oleophobic liquid hardener. The product prepared by the preparation method disclosed by the invention has a relatively good anti-permeability effect.
