METHOD OF LIQUID TYPED INORGANIC WATERPROOF AGENT

PURPOSE: A producing method of a liquid typed inorganic waterproof agent is provided to improve the intensity and the corrosion resistance of a concrete structure by being penetrated into the surface of the structure. CONSTITUTION: A producing method of a liquid typed inorganic waterproof agent comprises the following steps: forming a first solution by mixing oleic acid and purified water inside a reaction bath(S10); mixing sodium m-silicate with the purified water and dissolving the mixture to make a second solution(S20); forming an ivory white syrup by inserting the second solution to the first solution(S30); and mixing silica sol with the ivory white syrup(S40). The ivory white syrup is produced by maintaining the temperature of the reaction bath at 40 deg C, and inserting the second solution slowly over 1 hour while stirring the mixture in an 80 rpm speed.
