JPS5913982B2 - Method for manufacturing grooved decorative paper overlay panels - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing fluted decorative paper overlay panels.

Conventional methods of manufacturing grooved overlay panels tend to suffer from the following drawbacks.

In other words, in the method of overlaying the decorative paper 2a on the base plate 1a and cutting the grooves without applying a sanding sealer and drying as shown in Figs. Not only does it protrude to the edges of the grooves, making the grooves unclear (Fig. 10), but the surface of the overlaid decorative paper 2a becomes fluffy (Fig. 2), and the base plate 1
It is difficult to make the surface smooth due to the fiber pattern in a, conduit hole marks, press dust marks, etc. Furthermore, as shown in FIG. 3, delamination may occur within the decorative paper 2a. This was a cause of deterioration of the design of the decorative board. The present invention aims to solve the problems of the prior art in the method of manufacturing such an overlay panel.

That is, the method of the present invention impregnates the decorative paper 2 with the sanding sealer 55 and attaches it to the base plate 1, and then performs groove cutting and sanding to remove the fluff of the conventional decorative paper 2. The present invention aims to provide a grooved decorative paper overlay panel with a high design quality that is free from unevenness, interlayer peeling, and ambiguity due to six grooves. Embodiments of the method of the present invention illustrated in the drawings will be described below.

1. Overlay of decorative paper 2 (Figures 4 and 5) ■ As the base plate 1, a common decorative paper base plate such as plywood, hardboard, asbestos cement board, etc. is used.

15 Any pattern 3 such as wood grain or abstract pattern on the surface of this base plate 1
The decorative paper 2 printed with is adhered using a laminator.

However, since this decorative paper 2 is a general paper, fine irregularities such as fuzz 4 on the surface and fiber patterns on the surface of the base plate 1 are likely to occur. (Figure ■04, Figure 5) 2 Application of sanding sealer (Figure 6) ■Next, apply this decorative paper 2
A permeable sanding sealer 5 such as polyester resin, urethane resin, lacquer resin, etc. is applied to the surface using a flow coater 5-, a roll coater, or the like.

Subsequently, the sanding sealer 5 is dried and hardened. The sealer 5 penetrates into the fiber gaps of the porous decorative paper and strengthens the bond between the layers of the printing base paper. (Figure 6) ■03 Grooving (
(FIG. 1) ■Next, as shown in FIG. 1, a groove 6 having an arbitrary shape such as a V-shaped cross section, a round shape, or a square shape is formed on the surface of the base plate after the sealer 5 has been applied using a groover, a cutter, or the like.

In this case, since the decorative paper on the surface is hardened with Sunday sealer 5, the decorative paper is not torn during groove processing or delamination occurs, and the clear grooves 6 of the ring are formed.
can be formed. 4-groove painting (Fig. 8). Next, as shown in FIG. 8, a groove paint 7 is applied inside the groove 6 using a ring coater.

In this case, in the conventional technology, the amount of paint 7 applied fluctuates and the ring of the groove tends to become unclear, but in the present invention, as described later, excess paint can be removed by sanding, so the amount of paint 7 applied The fluctuation in is not related to the finish of the product. Rather, in the case of the present invention, it is better to apply a slightly larger amount of paint 7 so that there is no uncoated area in the grooves 6. After painting, the groove paint 7 is dried.

5. Surface sanding (FIG. 9): Next, the entire surface of the decorative paper is polished using a belt sander, drum sander, etc. to remove fine irregularities 8 on the entire surface.

The fine irregularities 8 here refer to fuzz on the decorative paper 2, irregularities on the surface of the decorative paper 2 due to fiber patterns, irregularities of paint overflowing from grooves, etc. Since the decorative paper 2 is hardened with the sanding sealer even after sanding in this way, the printed pattern 3 will not disappear or delamination will occur even after sanding, and the surface will be smooth and the grooves will be smoothed. The circle is clearly expressed. Further, if necessary, direct printing may be further performed on the smooth surface of the decorative paper 2 thus formed.

6 Top coat (Figure 10): Finally, a transparent top coat 9 is applied to the entire surface using a flow coater or roller coater to protect the surface.

7 Substitution step. Incidentally, the steps 1 and 2 above, that is, the overlay of the decorative paper 2 and the application of the sanding sealer may be replaced as follows.

That is, the surface of the base plate 1 is impregnated with a sanding sealer such as polyester or urethane in printing base paper in advance,
The dried resin paper may be integrally molded by heat and pressure on the base plate 1 using a laminator or a hot press.

The subsequent steps are the same as described above. Since the present invention has the above-described configuration, its effects can be summarized as follows.

5 The ring of the painted groove can be clearly expressed.

5. The surface of the decorative paper 2 is finished smooth.

6. Peeling between the layers of the decorative paper 2, especially around the periphery of the groove 6, is less likely to occur.

That is, in the present invention, since the decorative paper 2 is impregnated with the sanding sealer 5, the decorative paper 2 becomes colloid and becomes an integral structure. Since this does not occur, the above-mentioned effects can be obtained.
