TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a decorative method for a building board in which cosmetic particles are sprayed on a surface of the building board.
[0002]
[Prior art]
Conventionally, when sand is sprayed as decorative granules on the surface of a building board, the surface of the building board flowing through the manufacturing process is subjected to undercoating or intermediate coating, and then sand is applied to the surface of the building board while the paint does not dry. Sand was being sown by a sprinkler. However, this method can uniformly scatter sand on the surface of the building board, but cannot scatter sand partially or partially except for sand.
[0003]
In addition, as a method of partially spraying the sand, after partially coating the surface of the building board by flexographic printing (topographic printing), gravure printing (intaglio printing), ink jet coating, etc., the sand is sprayed while the paint is not dried. There is a method of bonding sand only to paint. However, because the sand is scattered after painting, the sand only penetrates into the paint by its own weight, so the amount of penetration is small, the adhesion between the sand and the paint is weak, and even if the surface is rubbed after the paint has dried, There is a problem of peeling. In this case, a top coat is required after spraying the sand in order to retain the sand. (For example, see Patent Document 1)
