THE METHOD OF MANUFACTURING PAINTING COMPOSITE USED IN CONCRETE FLOOR TYPE

摘要

PURPOSE: A method for manufacturing a paint composition for concrete floor is provided to maintain properties of paint such as hardness or tensile strength in an environment where long-term storage is difficult by various harmful factors such as acid rain, toxic gas, and dust. CONSTITUTION: A method for manufacturing a paint composition for concrete floor comprises the steps of: preparing a first mixed solution by heating polypropylene glycol and amide; preparing a base material part by successively adding pigment, polypropylene glycol, dispersing agent, polyethylene, calcium bicarbonate and xylene to the first mixed solution and then adding an antifoaming agent; preparing a hardener part by adding polypropylene glycol, sulfuric acid and plasticizer and heating them, and adding isocyanate and a promoter to the mixture; and mixing the base material part and the hardener part in a weight ratio of 2.5:1-3.5:1.
