[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for making a building board in which cosmetic particles are distributed on the surface of the building board.
[0002]
[Prior art]
Conventionally, when sand is distributed as a decorative granule on the surface of a building board, after applying the undercoating or intermediate coating on the surface of the building board flowing through the manufacturing process, the sand is applied to the surface of the building board without drying. I was scrubbing the sand with a whisper. However, with this method, sand can be uniformly spread on the surface of the building board, but it was not possible to spread sand partially or to remove sand except for a part.
[0003]
In addition, as a method of partially spreading sand, after partially painting the surface of the building board by flexographic printing (letter printing), gravure printing (intaglio printing), ink jet painting, etc., sand is applied while the paint does not dry. There is a method of adhering sand only to the paint part. However, since sand is spread after painting, the sand only enters its own weight, so the amount of intrusion is small, the adhesive strength between the sand and the paint is weak, and even if the surface of the paint is dried, There is a problem of peeling off. In this case, in order to hold the sand, a top coat is required after the sand is spread. (For example, see Patent Document 1)

A cylindrical transfer roll 4 is similarly provided below the left side of the roll 1, and the transfer roll 4 is provided so that the shaft 14 of the transfer roll 4 is in contact with the roll 1 and is horizontal.
[0015]
Two paint supply rolls 5 are provided above the right side of the roll 1, both of which are provided so that the shaft 15 of the paint supply roll 5 is horizontal, and one paint supply roll 5 a is in contact with the roll 1. The other paint supply roll 5b is provided in contact with the one paint supply roll 5a, and the heights of the two paint supply rolls 5 are substantially the same.
[0016]
The roll 1 rotates counterclockwise, and the transfer roll 4 rotates clockwise. One paint supply roll 5a in contact with the roll 1 rotates clockwise, and the other paint supply roll 5b rotates counterclockwise.
[0017]
A sanding machine 7 is provided above the roll 1, and the cosmetic particles 3 are placed in the sanding machine 7, and the cosmetic particles 3 are spread on the surface of the roll 1 positioned below the sanding machine 7. It can be done. The cosmetic particles 3 include sand, beads, aggregates, and the like.
[0018]
The building board 6 is a flat plate and flows leftward in contact with the lower end of the transfer roll 4.
[0019]
Next, the makeup | decoration method of the building board 6 is demonstrated.
[0020]
First, the paint 2 is injected from above between the two paint supply rolls 5 in contact with each other,
The paint 2 is injected between the two paint supply rolls 5 one after another while adjusting the accumulated amount of the paint 2.
[0021]
Next, the paint 2 supplied to the paint supply roll 5 adheres to the surface of the roll 1 after adhering to one paint supply roll 5 a in contact with the roll 1. After the paint 2 is attached to the surface of the roll 1, the cosmetic particles 3 squeezed downward from the sanding machine 7 located above the roll 1 are attached on the paint 2.
[0022]
In addition, since the roll 1 has irregularities and the paint is applied only to the convex portions 9, the cosmetic particles 3 remain only on the convex portions 9 when the cosmetic particles 3 are distributed. On the other hand, since the paint 2 does not adhere to the recess 10 of the roll 1, the cosmetic particles 3 do not adhere to the recess 10, and the cosmetic particles 3 that have fallen into the recess 10 are positioned above the transfer roll 4. It is collected by the sand receiver 8 and returned to the sanding machine 7 again for use.
[0023]

Therefore, the cosmetic particles 3 can be firmly held on the surface of the building board 6 by being pushed into the paint 2 by the roll 1 and the transfer roll 4.
[0025]
Further, since the roll 1 is provided with irregularities and the paint is attached only to the convex portions 9, even if the cosmetic granules 3 are distributed, the cosmetic granules 3 remain only on the convex portions 9, and the building board 6 is a flat plate. The cosmetic granules 3 can be partially attached to the surface of the building board 6 via the transfer roll 4.
[0026]
Furthermore, the supply amount of the paint 2 can be kept constant by injecting the paint 2 between the two paint supply rolls 5 in contact with each other while adjusting the accumulation amount of the paint 2. In addition, by changing the distance between the two paint supply rolls 5 and at the same time, changing the supply amount of the paint 2, the thickness of the coating film can be adjusted and the adhesion amount of the cosmetic granules 3 can be adjusted. Can also be changed.
[0027]
Next, an example when the surface of the roll 1 has no irregularities will be described.
[0028]
As shown in FIG. 3 or 4, when the surface of the roll 1 is smooth and smooth, the coating 2 can be applied to the entire surface of the roll 1, so that the cosmetic particles 3 are also applied to the entire surface of the roll 1. Therefore, it is not necessary to provide the sand receiver 8. Moreover, in this case, since the transfer roll 4 comes into contact with only the convex portions 21 of the building board 6 when the unevenness is provided on the building board 6, the cosmetic granules 3 are partially attached to the building board 6. It can also be made.
[0029]
