COATING MATERIAL OF ALUMINUM BUILDING MATERIAL FOR SURFACE ABRASION AND DURABILITY IMPROVEMENT AND METHOD FOR PRODUCING THE SAME

摘要

PURPOSE: Provided are a coating material which can conveniently remove contaminant on surface of aluminum building material and form a uniform coating layer capable of improving durability of surface layer, and which consists of environmentally friendly raw materials, and a method for producing the same. CONSTITUTION: The coating material consists of 1-20 wt% of abrasive, 0.1-10 wt% of surfactant, 1-10 wt% of crosslinking silicon-based resin, and the rest of water. The abrasive is at least one selected from the group consisting of active carbon, diatomaceous earth, acid clay predominantly consisting of silicon oxide or aluminum oxide, activated clay obtained by chemically treating the acid clay, silica gel of hydrous, amorphous silicon dioxide(SiO2·nH2O), or bentonite. The surface area of the abrasive is 1000-2500 m2/g.
