PURPOSE: An environment-friendly coating agent is provided to be economically used by recycling oyster waste shells, to enhance the stability as drinking water using a ceramic material which is harmless to a human body, and to improve the adhesive force of a coating layer. CONSTITUTION: A method for manufacturing a coating agent using oyster shells comprises the following steps: manufacturing oyster waste shell powder by washing, calcining, and braking the oyster shells; manufacturing an intermediate composition by mixing the oyster shell powder with white cement, metakaoline, Al_2O_3, and silica using a dry method; and mixing the intermediate composition with polyacrylic ester-based emulsion and water. |
