Normal-temperature wall coating based on ceramic underglaze painting and coating process of wall coating

The invention relates to the technical field of wall paint preparation, and discloses a normal-temperature wall coating based on ceramic underglaze painting and a coating process of the wall coating,the normal-temperature wall coating comprises a water-based coating A painted on the bottom layer of a wall, a water-based coating B painted on the middle layer of the wall, a ceramic underglaze painting coating painted on a wall pigment layer, and a glaze surface coating painted on the surface layer of the wall; and after the normal-temperature wall coating is constructed and smeared on a wall, the wall coating is divided into four layers, namely a water-based coating layer located on the bottom layer of the wall, a water-based coating layer located on the middle layer of the wall, a ceramicunderglaze painting coating layer located on the pigment layer of the wall and a glaze coating layer located on the surface layer of the wall in sequence. The coating obtained after construction has the advantages of corrosion
