In order to increase the height, a plurality of grooves are provided linearly.

  Thus, in order to give wear resistance and scratch resistance to the surface decorative material provided with the groove part, further prevent the transmission of socks and stockings, prevent the fibers of the cloth for wiping cleaning from remaining in the groove part, etc. Usually, finish painting is performed. As the above-mentioned finish paint, when coloring is applied, if the depth of the groove is within the thickness of the surface decorative material, the penetration of the finish paint will be substantially the same on the surface and the groove, and it can be finished with the same color tone. .

  However, since the surface decorative material is often used in the form of a sheet and is thin, the groove portion often reaches the base material. For example, MDF (density density) obtained by mixing wood fiber with an adhesive as a base material and hot pressing it. When 0.4 to 0.8 kg / cm 3) is used, this MDF layer is cut and grooved. If finish coating is performed in this state, the finish paint is absorbed on the exposed wood fiber surface of the MDF by capillary action, resulting in a wet color (black) and a different color tone from the surface, which impairs the design. Arise.

On the other hand, in the following Patent Document 1, a cosmetic material comprising a base material and a decorative sheet, and forming a groove portion by cutting from the decorative sheet side, the depth of the groove portion reaches a part of the base material, A cosmetic material is disclosed which is coated with a groove coloring paint having the same color as that of the base paper of the surface decorative sheet after the grooves are formed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a partial cross-sectional perspective view showing a grooved flooring A according to the present invention. FIG. 2 is an enlarged view showing a main part of FIG. As shown in FIG. 1 and FIG. 2, the grooved flooring A is a V-shaped groove having a substantially V-shaped cross section obtained by cutting the surface of a wooden flooring material obtained by attaching a surface decorative material 2 to a base material 1. 5 is provided, and the entire surface including the V-shaped groove 5 is finish-coated with a colored paint 4 for finish coating.

  As the base material 1, a composite material in which MDF 11 is bonded to a plywood 12 and combined is used, and a veneer is used as the surface decorative material 2. Usually, the colored paint 4 is transparent, translucent, or light-colored in order to make use of the grain of the veneer such as oak, birch, cherry, maple, etc., used as the surface decorative material 2, and coloring properties. The paint with is used. Under the colored paint 41 applied to the inner surface of the V-shaped groove 5, a coating film of the ground treatment agent 3 described later is formed.

  Below, the processing method of the grooved flooring A concerning this invention is demonstrated. FIG. 3 is an explanatory view schematically showing a state in which the V-shaped groove 5 is recessed on the surface of the wooden floor material in which the surface decorative material 2 is adhered and laminated on the base material 1 and cut to a predetermined size. . The V-shaped groove 5 is formed, for example, by grooving until reaching the MDF 11 layer of the substrate 1 with a V-shaped groove processing machine. At this time, since the wood fiber constituting the MDF 11 is exposed on the cutting surface 51 of the V-shaped groove 5, when the colored paint 4 is directly applied, it is absorbed by the capillary phenomenon, and the color is more than the portion other than the V-shaped groove 5. It becomes darker and shades appear in the color of the entire surface.

  Therefore, in the method of the present invention, the inner surface of the V-shaped groove 5 is pretreated. That is, the base treatment agent 3 containing scaly pigment in the range of 5 to 30% is applied to the entire surface including the V-shaped groove 5 and the surface decorative material 2 using a sponge-type roll coater. At this time, the content of the scaly pigment of the ground treatment agent 3 was adjusted in the range of 5 to 30% in accordance with the absorbance of the colored paint 4 in the V-shaped groove 5, and adhered to other than the V-shaped groove 5 after application. Excess surface treatment agent 3 is scraped off. Usually, the scraping step of the surface treatment agent 3 is performed by a so-called wiping method in which the surface of the roll coater is scraped using a plating roller in which metal plating is performed.

  As the scaly pigment, powdery or scaly colored mica or aluminum having a larger particle diameter than the roughness of the wood fibers constituting the MDF 11 is used. Thus, by covering the cutting surface 51, excessive absorption of the paint can be suppressed. FIG. 4 is an explanatory view schematically showing a state in which the surface treatment agent 3 is applied to the inner surface of the V-shaped groove 5 and the cutting surface 51 is coated with the surface treatment agent 3 as described above.

  As shown in FIG. 4, the wood fibers constituting the MDF 11 are coated with the base treatment agent 3, and the absorption between the V-shaped groove 5 and the surface decorative material 2 is substantially the same. It can be painted in harmony without color irregularities. At this time, as the colored paint 4, a transparent, translucent or light-colored colored paint 4 is used so as to make use of the grain of the veneer used as the surface decorative material 2. Usually, a rubber roll coater is used. Applied.

  The V-shaped groove 5 is ground-treated with the ground-treating agent 3 and its affinity with the colored paint 4 is slightly reduced. Therefore, a highly-bonded aqueous isocyanate is added to the colored paint 4 as a coating film adhesion improver. It is preferable to add. By doing in this way, the adhesiveness of the colored coating material 4 in the V-shaped groove | channel 5 improves, and can apply | coat with a roll coater with sufficient workability | operativity. Thus, the grooved flooring A shown in FIGS. 1 and 2 can be obtained by carrying out the grooved flooring processing method of the present invention.

  Although the said embodiment demonstrated the groove part of a cross-sectional V shape, any form, such as concave shape and U shape, may be sufficient besides that. The method for forming a coating film in the method of the present invention has been described with respect to the case of using a roll coater, but is not limited to the roll coater method, and can be performed by a known method such as brushing or spray coating. As described above, the method of the present invention can be modified in various ways, and each case belongs to the technical scope of the present invention without departing from the scope of the claims.
