SILVER COATING CERAMIC AND SILVER COATING COMPOSITION AS WELL AS SILVER COATING METHOD

摘要

The present invention is for coating porcelain and it relates to a coating composition and the coating method, to solve The technical challenge is no stain, and a crack for improved wetting and drying rate of the sol is used to form a coating film. ; aspect of the solution according to the invention for this purpose is a solution-based sol, is added to improve the wettability increases the viscosity of the sol dispersing agent, is added comprises acetone and methanol to increase the drying rate of the sol coating composition is disclosed. ; In addition, the present invention A method for forming a coating film is immersed in a ceramic coating composition described above is another aspect of the method according to the resolution, is at least one time in the dipping and drying process of the ceramic coating composition to increase the thickness of the coating film repeating the steps of immersing and drying, temperature 300-600 , time 50 to 70 minutes in a reducing atmosphere of N2 gas, CO gas, this is a coating method comprising the step of heat treatment while flowing a mixed gas of CO2 gas for the heat treatment is started .
