Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a decorative board for building materials whose surface is electrostatically flocked.

Conventional decorative boards of this type have either had a pattern printed directly on the surface of a wood-based plate-like substrate such as plywood, or have decorative paper or fabric printed with a pattern attached to the plate-like substrate.

However, such a decorative board has a flat surface and the pattern itself does not have a three-dimensional effect, so it lacks the so-called high-class feel. It also has poor sound absorption and heat insulation properties.

On the other hand, in order to obtain heat retention and sound absorption properties, insulation boards, glass fiberboards, mineral fiberboards,
Many decorative boards using low specific gravity plate-like substrates such as lightweight foam boards are also commercially available.

However, when these plate-like substrates with low specific gravity are used, printing of the surface pattern is limited, and a high design quality cannot be obtained. Furthermore, since this low specific gravity plate-like substrate has low strength and surface hardness, it is only used as a sound-absorbing and heat-insulating base material for ceilings, walls, floors, etc.

Furthermore, as a means of improving sound absorption and heat retention,
Attempts have also been made to make a large number of small holes in a plate-like substrate (the former), or to make a plate-like substrate by combining a low-density plate and a wood-based plate (the latter). but,
In the former case, the design of the surface deteriorates as a result of making a large number of small holes. In the latter case, the manufacturing process is complicated and workability is low.

For this reason, attempts have been made to electrostatically flock fibers onto the surface of a plate-like substrate, and to use this flocked layer to simultaneously provide the decorative board with design properties, heat retention properties, sound absorption properties, strength, etc.

However, in this type of decorative board, for example, as seen in Utility Model Application No. 48-94612, the surface of the gypsum board is covered entirely or in a predetermined pattern.
In the case of flocked fibers with a length of 0.5 to 5 mm,
Flocked fibers can only express a surface design with extremely poor three-dimensionality, in which long fibers and short fibers are simply flocked in a monotonous, flat or patterned manner, making it difficult to use as a building material. The decorative quality and commercial value of the product have been reduced.

In addition, as a technique to eliminate this monotonous three-dimensional effect, there is a technique as shown in Utility Model Application Publication No. 54-13224, in which fibers of different lengths are differentiated in a pattern and flocked.

However, even with this prior art, the expression could not go beyond the three-dimensional design expression such as the unevenness caused by the flocked layer.

For this reason, until now, no technology has been proposed that can realize the novel design expression required for flocked boards.

The present invention aims to solve the problems of conventional cosmetics of this type.

That is, as described below, in the present invention, piles of different lengths are implanted on the surface of a plate-like substrate, and the long piles and short piles are selectively used to form a pattern and unevenness. .

Embodiments of the present invention will be described below based on the drawings.

(1) FIG. 1 shows an embodiment of the present invention.

1 is a plate-like substrate, such as plywood, fiberboard, wood chip board,
It is an organic or inorganic plate such as a calcium silicate plate, or a mixed or composite plate of organic and inorganic substances.

2 is an adhesive to be applied on the plate-like substrate 1, which may be epoxy, phenol, vinyl chloride, vinyl acetate resin adhesive, or solvent-based adhesive such as natural or synthetic rubber, polyurethane, or acrylic ester, vinyl acetate, or acrylic. Emulsion type adhesives such as acid esters and plywood rubber are used.

The adhesive 2 is preferably transparent or translucent, or becomes transparent or translucent after curing.

3a and 3b are piles to be flocked.

Next, a method for manufacturing the decorative board will be explained.

As shown in FIG.
It is applied partially and in a pattern on the surface. As a coating device, a spreader, a roll coater, a gravure printer, a screen printer, etc. (indicated by r in the drawings) are used.

If necessary, the surface of the plate-shaped substrate 1 may be subjected to a base treatment such as sealing treatment, sealer treatment, sanding treatment, intermediate coating, or base treatment such as papering or cloth pasting.

A decorative pattern is formed on the surface of the plate-like substrate thus obtained. The decorative pattern may be formed by directly printing the decorative pattern on the surface of the base-treated plate-like substrate 1, or by pasting decorative paper or cloth on which the decorative pattern is printed.

Next, piles 3a and 3b are electrostatically flocked to the areas where the adhesive has been sprayed. This electrostatic flocking method is not particularly different from general methods.

As the piles 3a and 3b, short fibers, long fibers, etc., synthetic resin piles such as human silk, duplex pile, nylon, cashmilon, vinylon, and corderan, wool piles, etc. are used.

The piles 3a and 3b may be transparent, opaque, raw pile, or may be colored arbitrarily.

However, at this time, the pile must be flocked in such a way that the decorative pattern formed on the plate-like substrate can be seen from the outside.

For example, when using opaque pile,
The pile must not be so densely flocked that it completely conceals the decorative pattern.

In addition, if the pile is transparent, regardless of whether it is colored or colorless, dense flocking is possible to the point where the decorative pattern can be seen through.

Next, the adhesive 2 is dried and hardened using a drying device 4.

If necessary, a top coat may be applied without filling the piles 3a and 3b.

In this case, a paint or a coating method must be used for the top coat that allows the decorative pattern on the plate-like substrate to be seen through.

In this way, the desired decorative board can be obtained.

In the obtained decorative board, the two-dimensional expression of the decorative pattern formed on the surface of the plate-like substrate can be seen through the uneven pattern formed by the long and short piles flocked on the surface, so it can be expressed two-dimensionally. The decorative pattern is projected in a three-dimensional manner into the shape of long and short piles, so the viewer can arbitrarily select the viewing position, angle, and incident light situation. The decorative pattern formed there can now be seen as a three-dimensional object that stands out, allowing for a new, complex and excellent design expression as a decorative board that has never existed before. It is something that will be realized.

(2) As shown in FIG. 3, piles 3a and 3b are implanted on the surface of the decorative paper or decorative cloth 5 in advance and the piles 3a and 3b are wound onto the winding roll 6, and then the plate-shaped substrate 1 is It may be adhered to the top with adhesive 2.

(3) As shown in FIG. 1, the decorative board of the present invention has piles 3a and 3b of different lengths planted on a plate-like substrate 1,
Although the long pile 3b is patterned to form an uneven pattern, in this case, the long pile 3b and the short pile 3a may be flocked at the same time, or may be flocked separately over time.

(Effects of the present invention) The two-dimensional expression of the decorative pattern formed on the surface of the plate-like substrate can be seen through the uneven pattern formed by the long and short piles that are flocked on the surface. The decorative pattern is projected in a three-dimensional manner into the shape of long and short piles, so the viewer can arbitrarily select the viewing position, angle, and incident light situation. The decorative pattern formed there can now be seen as something that stands out with a three-dimensional effect, realizing a new complex and excellent design expression as a decorative board that has never existed before. I came to the conclusion.

The long and short piles that are flocked not only work together with the decorative pattern formed on the surface of the plate-like substrate to create an excellent surface design, but also improve its mechanical cushioning effect and reduce the frequency of contact with the outside air. Therefore, the decorative pattern on the surface of the plate-like substrate is protected from external impact and pollution, and damage and fading caused to the decorative pattern over time are extremely effectively prevented.

Therefore, the decorative pattern formed on the plate-like substrate can maintain its original beautiful design over a long period of time, contributing to improved durability as a decorative board for building materials.

The structure of the present invention has the above-mentioned functions and effects, and overcomes the common sense of the conventional flocked board, which simply used piles of different lengths for flocking, which could only produce a monotonous uneven expression. overturn,
While realizing a completely new design expression that combines two-dimensional and three-dimensional elements, it also improves the durability of this decorative board at the same time.
