Abstract

PURPOSE:To emphasise a formed embossed pattern, by forming the embossed pattern to the surface of a building panel before successively coating said building panel with two kinds of paints having mutually different color tones. CONSTITUTION:Two kinds of paints 4 having mutually different color tones are successively applied to the surface 3 of a building panel 2 to which an embossed pattern 1 is formed. By this method, because flowing difference is generated between recessed and protruded parts of the pattern while the coating amount becomes little in inclined parts and color tone is also different, large difference is developed and the depth of recessed parts increases still further.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a decorative method for architectural boards that emphasizes the uneven pattern formed on the surface.

[Background technology]

Conventionally, architectural boards with an uneven pattern are simply coated with one type of paint, but it is not possible to emphasize the uneven pattern by adding depth to the recesses, resulting in a monotonous makeup. there were.

[Purpose of the invention]

An object of the present invention is to emphasize the uneven pattern formed on a construction board.

[Disclosure of the invention]

The decorative method for architectural boards of the present invention is characterized by sequentially applying two types of paints (4) having different tones to the surface (3) of the architectural board (2) on which the uneven pattern fi+ has been formed.

The present invention will now be described in detail with reference to the accompanying drawings. (
2) is a construction board such as a flat roofing material, and the planar surface (3) K forms an uneven pattern (1).

The concave portion (5) of this uneven pattern fil has a depth of 0.3 to I,
Oam, width 0.3-1.0 fins, hitch P0.5-5.0 pharynx between the four parts (5). This architectural board (2) is
・As shown in the figure, belt conveyor 1 = (61) is conveyed toward the sifting flow rotor (7).Flow coater (7)
Two of them are arranged along the direction of movement of the construction board (2). The flow coater (7) is supplied with a circulation bomb from the paint tank (8).
[91, the paint (4) is sent to the head (Iri) via the circulation pipe (10), is discharged from the discharge nozzle (not shown) at the lower end of the head (river) so as to form a flow curtain θ, and is discharged from the saucer (13). ) and is circulated to the paint tank (8).The paint tank (8) located on the front side with respect to the direction of movement of the architectural board (2) contains paint containing light-colored pigments. (4), and paint (4) containing dark pigment is poured into the rear paint tank (8).However,
You can also do it the other way around. This paint (4) is a transparent water-based emulsion =! Bamboo solvent type paint with viscosity of 500-20
00 cps. Therefore, the construction board (2) is conveyed by the belt conveyor (6) across the front and rear flow curtains, and two types of paint (4) of different colors are applied to the surface (3) of the construction board (2). Apply. Note that the surface (3) of the building board (2) is preheated to 40 to 60°C. In this case, the fourth part (6) of the uneven pattern +11 and the convex part Q4)
This causes a difference in the flow of the paint at the inclined part (
+5), the amount of coating is small and a difference in color tone occurs between the concave portion (5) where the two types of paint (4) accumulate and mix. Furthermore, since the amount of coating is greater in the recessed portion (5) than in the convex portion θ4), the depth of the fourth portion (5) is further increased.

After applying the two types of paints (4) with different tones in this way, the construction board (21) is conveyed to a dryer (not shown) by a belt conveyor (6) to dry and bake the paint (4). Finish the decoration of the architectural board (2).

〔Effect of the invention〕

In the present invention, since the paint is applied to the surface of the architectural board on which the uneven pattern is formed, there is a difference in the flow of the paint between the concave and convex parts of the uneven pattern, and the amount of paint applied is reduced on the sloped parts. Moreover, since two types of paint with different tones are applied sequentially, there is a large difference in color tone between the sloped part where the amount of paint is small and the concave part where the paint accumulates, further increasing the depth of the four parts and emphasizing the uneven pattern. It is something that can be done.
