[0003] However, in the above-mentioned finishing method, if the color tone difference between the color of the surface of the object to be painted and the color of the spray-coated paint is relatively large, the boundary between the surface of the object to be painted and the paint of spray-coated paint will be remarkably shown, and it is difficult to use a paint finish. A pattern that forms slowly changing hues, such as that of a yohen style monier

Embodiment

[0031] Hereinafter, the present invention will be specifically described based on examples.

[0032] Finished panels were manufactured using the finishing apparatus shown in FIG. 1 . A long steel plate having a width of 914 mm and a thickness of 0.35 mm was used as the metal substrate 2 .

[0033] As the base paint 1, a polyester-based resin paint ([S03-G4651] manufactured by NOF BASF Co-Tingsu Co., Ltd.) was blended with a pigment and colored light orange was used. In addition, the viscosity (20° C.) of the base paint 1 was 60 seconds as measured by a Ford cup No. 4.

[0034] As the finishing paint 3 a having the same color as the base paint 1 , what was obtained by diluting the base paint 1 with a solvent containing cyclohexanone and solvent naphtha as main components was used. The viscosity (20° C.) of this finishing paint 3a was 30 seconds as measured with a Ford Cup No. 4.

[0035] As the finishing paint 3b having a color different from that of the base paint 1, a pain...

Abstract

A manufacturing method of painting plates is provided to easily form so that a color tone is changed slowly. The manufacturing method of painting plates comprises the steps of: applying a base paint(1) on a surface of a metal substrate(2); and spray-applying a multi-colored finish paint(3) to an applying side of the base paint on the metal substrate so that the finish paint(3a) having the same color as the base paint and the finish paint(3b,3c) having a different color from the base paint overlap partially. The finish paint having the same color as the base paint is prepared by diluting the base paint. The boundary line between the finish paint (3b, 3c) having a different color from the base (1) and the base paint is indistinctive by mixing the finish paint (3a), (3b), (3c).

Description

technical field [0001] The present invention relates to a method for producing a painted board used as a building material such as a roofing material or a wall material, and more particularly to a manufacturing method used for producing a multi-colored painted board with high designability. Background technique [0002] Conventionally, a multi-color pattern coating film has been formed by spraying two or more colors of paint on a strip-shaped object moving at a speed of 10 m / min or more (for example, refer to Patent Document 1). In the finishing method described in Patent Document 1, at least two or more than two paint spray nozzles are used to spray different color paints of at least two or more colors, thereby spraying from each paint The paint ejected from the nozzle forms a mixed multi-color spray pattern. [0003] However, in the above-mentioned finishing method, if the color tone difference between the color of the surface of the object to be painted and the color of ...
