(57) [Summary] [Purpose] Strong on the surface of metal, concrete, etc. It forms a low-temperature curable ceramic / organic polymer composite coating film with excellent water resistance, weather resistance, and chemical resistance. [Structure] Al (O H) 3 , Na 2 Al 2 O 4 and ZnO are added with water and hot water and stirred, and a solution obtained by adding an aqueous solution of boric acid to the solution and mixing is added and mixed, and then CaSiO 3 and Al 2 ( SiO 3 ) Into the mixed solution obtained in the first step of adding 3 and performing wet pulverization, one or more kinds of fine powder such as ZrO 2 , petalite, and a calcined product of pearlite, and Ca (OH) 2 · CaCO 3 In addition, after adding and mixing the inorganic pigment, the second step of performing wet pulverization to obtain a solution-type coating agent, and applying the coating agent obtained in the second step to the surface of the base material at room temperature to 400 ° C. The third step of forming a decorative ceramic coating film by curing with, and the surface of the coating film obtained in the third step is coated with a copolymer resin prepolymer having a carboxyl group-water emulsion, polymerized and cured, and applied. Fourth step of forming a film. |
