Description

[Detailed Description of the Invention] The present invention relates to a decorative board for building materials whose end surface is electrostatically flocked.

The applicant previously filed an application regarding a decorative board for building materials that was electrostatically flocked. By the way, since this type of decorative board is constructed by butting the wood ends together, the butt joints are exposed, spoiling the appearance, and causing the wood ends to squeak against each other, producing noise.

The present invention aims to solve these problems of the prior art. That is, in the present invention, by planting hair on at least the upper part of the butt end surface 1a of the plate-shaped substrate a near the surface 1b and the part of the surface 1b near the butt end surface 1a, the butt end part is not exposed and the sound is emitted. It was designed to prevent this.

Embodiments of the present invention illustrated in the drawings will be described below.

A is a plate-like substrate, which is an organic or inorganic plate such as plywood, fiberboard, wood chip board, calcium silicate board, or a mixed or composite plate of organic and inorganic materials. The surface of the substrate a is subjected to surface treatment such as sealing treatment, sealer treatment, sanding treatment, undercoating, intermediate coating, etc., or surface treatment such as pasting with paper or cloth, as required.

In addition, surface treatments such as sealing, undercoating, and intermediate coating are applied to the wood end surfaces that have been actually processed, joined, and chamfered.

Furthermore, a pattern may be printed on the surface of the base-treated substrate a, or a pattern-printed decorative paper or cloth may be printed or attached.

b is an adhesive that is applied to the plate-shaped substrate a and the end surface of the wood to flock the pile c, and is an epoxy, phenol, vinyl chloride, vinyl acetate resin adhesive, or a solvent such as natural or synthetic rubber, polyurethane, or acrylic ester. Emulsion type adhesives such as mold adhesives, vinyl acetate, acrylic esters, and synthetic rubbers are used.

The adhesive b is applied to the surface and end surface of the substrate a using a spreader, roll coater, flow coater, spray, gravure printing machine, or the like.

Pile C to be flocked includes short fibers, long fibers, human silk, souff pile, nylon, cashmilon,
Synthetic fiber piles such as vinylon and corderan, hair piles, etc. are used.

The pile c may be transparent, opaque, raw pile, or optionally colored.

The pile c that is flocked on the surface may be a combination of long and short fibers. Further, after flocking, a top coat may be applied without filling the pile c.

As shown in FIGS. 1 to 4, the pile c is electrostatically flocked at least in the upper part of the pile near the end surface 1a and in the portion of the surface 1b near the end surface 1a. However, surface 1
It is desirable that the flocked portion b has a ring shape that matches the surface decorative pattern when the decorative boards are connected. Next, the flocking state of each of the shapes of the butt ends shown in the drawings will be explained.

Regarding Fig. 1: In Fig. 1, the butt end surface 1a is not processed in any way.
This shows the case where adjacent decorative boards are butted against each other. In this case, as shown in FIG. 1a, if the entire butt end surface 1a is flocked, no gap will be created at the joint, and the butt butt part will be stabilized. However, as shown in FIG. 1b, even if the hair is planted only on the upper part of the butt end surface 1a, there is no problem in practice, and there is an advantage that the hair-planting process is easy.

In this way, the end surface 1a of the end surface 1a and the end surface 1a of the surface 1b
By implanting hair in the area close to the area, the exposed joint area will not be exposed and will not produce any squeaks.

Regarding Fig. 2: Fig. 2 shows the case where the butt end surface 2a is actually processed. In actual processing, it is technically difficult to implant hair on the entire butt end surface 2a as shown in FIG. 2a. Therefore, as shown in Fig. 2b, the end surface 2 is close to the surface 2b.
It is advantageous to implant hair only in the vertical plane of a.

Regarding Fig. 3: Fig. 3 shows the case where the butt end surface is joined. In this case as well, it is considered more advantageous to implant the hair only on the vertical surface of the butt end surface 3a near the surface 3b as shown in FIG. 3b, rather than to implant the hair over the entire butt end surface as shown in FIG. 3a.

Regarding FIG. 4: FIG. 4 shows a case where the surface end edge of the end surface 4a is chamfered. In this case, the butt butt part will be more stable if the entire butt surface 4a is flocked as shown in FIG. 4a than in the case shown in FIG. 4b. However, even if the hair is implanted only in the chamfered part as shown in FIG. 4b, the thrust joint part will not be exposed.

Regarding Fig. 5: Fig. 5 shows the state of flocking at the corner of the boundary between the surfaces of the butt ends or the corners within the butt ends. In general, Figure 5b
As shown in FIG. 5A, since the density of flocking becomes smaller at the corners when viewed from the surface side, it is desirable to implant the flocks in a somewhat dense manner as shown in FIG. 5a. (On the contrary, it may be roughened.) Regarding Fig. 6: As shown in Fig. 6, it is desirable that the hoops of the flocked part of the surface near the butt end match the surface decorative pattern.

(Operations and Effects of the Present Invention) Since at least the butt end surface and the portion of the surface near the butt end surface are flocked, the butt butt part is not exposed and there is no squeak between the butt ends.
