Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing painted artificial decorative materials such as painted artificial decorative veneers.

Recently, the following methods have been considered in an attempt to express three-dimensional concentrated vessels such as those found in the porosphere of natural oak wood. In other words, after toning raw wood veneers to an appropriate color tone, multiple sheets are laminated with adhesive, and then pressed together with a pair of flat molds.
The resulting first frit is then subjected to slicing (straight grain cutting) to produce a first slice veneer. Next, this is made into a veneer for expressing the pore area, and is laminated with a commonly used veneer (veneer for expressing the non-porous area) via adhesive, and then pressed with a pair of uneven molds that have unevenness on the mold surface. A proposed method is to create a secondary flitch, then slice it parallel to the laminated surface to create an artificial decorative veneer, and then apply a wiping paint to the surface of the veneer. However, this method expresses the vessels using the adhesive layer (appearing like wood grain) of the primary sliced veneer, so the vessels appearing on the veneer surface of the decorative veneer are flat. Even if a wiping coating treatment is applied, the wiping paint does not penetrate into the vessel portion, resulting in a problem in that the wiping effect (imparting a three-dimensional effect by raising the vessel tube) is not achieved.

This invention was made in view of the above circumstances, and consists of a veneer for expressing the pore zone and a veneer for expressing the non-pore zone, in which elongated wood layers are alternately distributed with elongated adhesive layers. A method for producing a painted artificial decorative material, in which a fritsch is made by laminating and bonding together, the fritchi is processed to make an artificial decorative material, and the artificial decorative material is coated with a wiping paint to obtain a painted artificial decorative material,
The gist of this is that the adhesive layer of the veneer for expressing the porosphere is composed of an adhesive that dissolves in the solvent used in the wiping paint.

In other words, by doing this, the surface portion of the adhesive layer for expressing the vessel that appears on the surface of the artificial decorative material will be dissolved in the wiping paint solvent, and the wiping paint will enter into the dissolution trace, so that the vessel will not be visible. It becomes more embossed and has a richer three-dimensional feel.

The adhesive constituting the adhesive layer of the veneer for expressing the porosphere may be any adhesive as long as it dissolves in the wiping paint solvent, such as a chloroprene rubber adhesive.

Furthermore, examples of the wiping paint solvent include thinner.

Next, the present invention will be explained in detail based on examples.

EXAMPLE A plurality of raw wood veneers are coated with a chloroprene adhesive and stacked on top of each other, and then pressed together with a pair of flat molds to obtain a primary frit 1 as shown in FIG. In FIG. 1, 2 is a raw wood veneer, and 3 is a chloroprene adhesive layer. Next, this primary fritsch 1 is sliced perpendicular to the laminated surface and parallel to one side thereof (straight-grained).
As shown in Fig. 2, the elongated wood layer 2' (consisting of raw wood veneer 2) and the elongated adhesive layer 3' (consisting of the chloroprene adhesive layer 3) are alternately distributed. Make a veneer 4 for expressing the hole area. Next, this veneer 4 for expressing the pore area and a commonly used veneer (veneer for expressing the non-porous area) are alternately stacked with adhesive, and a concave-convex mold with a curved mold surface is made. It is pressed to create a curved secondary fritch 5 as shown in FIG. In Figure 3, 6 is a single plate for expressing non-porous areas;
Reference numeral 7 denotes an adhesive layer for bonding the veneer 4 for expressing the pore area and the veneer 6 for expressing the non-pore area. Next, this one song 2
Next, the flitch 5 is sliced (grained) into a substantially flat surface on the laminated surface. As a result, an artificial decorative veneer 8 as shown in FIG. 4 is obtained. On the veneer surface of this artificial decorative veneer 8, vessels 7a are expressed by the chloroprene adhesive layer 3' of the veneer for pore space expression (Fig. 3) 4, and these vessels 7a are arranged in rows. They line up to form a pore sphere. Next, a wiping paint (containing a thinner solvent) is applied to the veneer surface of the artificial decorative veneer 8 obtained as described above, and a wiping treatment is performed. Through this treatment, the surface portion of the chloroprene adhesive layer 3' representing the vessel 7a is dissolved in the wiping paint solvent (thinner), and the wiping paint enters into the dissolution trace. As a result, the vessel tube 7a has a protruding shape, giving it a rich three-dimensional effect. In other words, when wiping paint is applied to natural oak wood, etc., the wiping paint gets into the vessels and the vessels appear to stand out. The same effect can be obtained by applying wiping paint to decorative veneer.

In the above embodiment, the curved secondary fritches 5 are sliced to create a painted artificial decorative material, but the processing to be applied to the fritches 5 is not limited to slicing, and may include planing, planing, etc.
It may be sawed, polished, etc., and the artificial decorative material obtained thereby may also be plate-shaped or columnar.

Since the present invention produces an artificial decorative material in the manner described above, it is possible to obtain a painted artificial decorative material in which the vessels appear to be embossed and has a rich three-dimensional effect.
