Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a noncombustible flocked decorative board for building materials, in which a noncombustible pile is flocked on the surface of a plate-like substrate.

Conventionally, this type of decorative board is made by applying a base treatment to the surface of a substrate such as plywood or fiberboard, and then printing a pattern, or by printing decorative paper, cloth, synthetic resin sheet, etc. with a pattern printed on it. It was attached. By the way, such a conventional decorative board has a smooth surface, lacks a three-dimensional effect, and is poor in design. Furthermore, the substrate, surface decorative paper, decorative cloth, etc. are flammable.
Poor fire and flame retardant properties. In addition, sound absorption and heat retention properties are also lacking, except when fiberboard is used as a substrate.

Furthermore, if the substrate were to be made nonflammable, the cost would be significantly increased.

Further, when the substrate is a fiberboard, although the fiberboard itself has sound absorbing properties, the surface is covered with a decorative surface, which ultimately reduces the sound absorbing effect. Furthermore, in order to maintain the sound absorption effect, there are cases where a large number of small holes are drilled in the decorative board, but drilling the small holes in this way is not only cumbersome, but also reduces the design of the decorative surface. .

The present invention aims to solve the problems of conventional decorative boards of this type. That is, the present invention provides a decorative board that has flame retardant properties, soundproofing properties, heat retention properties, and has a high design quality by electrostatically flocking piles treated with flame retardant treatment on the surface of a plate-like substrate. That is.

Examples of the present invention will be described below.

(Explanation of Examples) First, the manufacturing method of the decorative board of the present invention will be explained.

(1) First, the adhesive 2 is applied to the entire surface of the noncombustible substrate 1 or partially in a pattern. At the same time, the adhesive 2 is applied over the entire length of two or four sides of the end of the substrate 1. For example, as shown in Figs. 2 and 3, the entire surface or the real part of the butt end surface 3, such as real machining (Fig. 2) or interlocking machining (Fig. 3), on the two or four sides of the butt end of the noncombustible substrate 1. Adhesive 2 is applied over the entire length of only the upper vertical surface portion 3a.

Furthermore, when chamfering 4a is applied to the surface 4 of the wood end 2 or 4 sides,
The adhesive 2 is applied over the entire length of the chamfered portion 4a or over the entire length of each side of the end face 3 surface 4 including the chamfered portion 4a.

Examples of the noncombustible substrate 1 include an asbestos cement board, a calcium silicate board, a wood chip cement board, a gypsum board,
Calcium carbonate plates, ALC plates, metal plates, or fiberboards made of inorganic fibers such as rock wool, asbestos, mineral wool, glass fibers, and carbon fibers are used.

As the adhesive 2, organic adhesives such as epoxy, phenol, vinyl acetate, natural or synthetic rubber, polyurethane, and acrylic ester, and inorganic adhesives such as water glass are used. Also,
The adhesive 2 may be transparent, transparent after curing, translucent, or opaque, depending on the purpose.

The adhesive 2 is applied using a spreader roll coater, a gravure printer, a screen printer, or the like.

If necessary, the noncombustible substrate may be subjected to surface treatment such as sealing treatment, sanding treatment, undercoating, intermediate coating, or pasting with paper, cloth, or synthetic resin sheeting.

In addition, the end part of the board, the end part where actual processing has been performed, and the chamfered part are treated with sealing, sealer, etc.
Apply undercoat, intermediate coat, etc. as necessary.

A pattern may be printed on the surface of the noncombustible substrate that has been subjected to surface treatment, or decorative paper, decorative cloth, synthetic resin sheet, etc. may be attached.

Further, in this case, it is desirable to use inorganic materials as the filler, sealer, paint, and sheet-like material used for base treatment, and the printing ink, paint, and sheet-like material used for surface decoration.

(2) Next, a noncombustible pile is densely flocked onto the applied adhesive 2 using an ordinary electrostatic flocking device. Flocking is done in a pattern on the entire surface 4 or partially, and at the same time, it is also done on the end faces 3, 3' and the chamfered parts 4a, 4a'. Also, Kiguchi side 3,
When 3' is actually processed, there are cases where the hair is planted only on the vertical portions 3a and 3a' of the upper surface thereof, and cases where the hair is planted on the entire surface.

As the noncombustible pile p, fibers such as glass fiber, carbon fiber, asbestos, rock wool, and mineral wool are used. Further, electrodeposition treatment is performed as necessary. Noncombustible pile p is transparent pile, opaque pile,
Alternatively, translucent pile or opaque pile is selected depending on the required surface design.

Further, the pile p may be formed by combining long and short fibers p ₁ and p ₂ in a pattern as shown in FIG. In this case pile
Opaque piles are used for both p ₁ and p ₂ .

However, the decorative surface on the substrate 1 may be seen through by partially using a transparent pile.

After the pile p is flocked, it dries to harden the adhesive.

(3) If necessary, a top coat may be applied without filling the pile p.

(Actions and Effects of the Present Invention) (a) A noncombustible flocked decorative board can be obtained by flocking the noncombustible pile p on the surface of the noncombustible substrate 1.

(b) Productivity is high because a decorative board can be obtained with only two steps: adhesive application and flocking.

(c) Since the noncombustible pile p is flocked over the entire length of the end surface of the noncombustible substrate 1, there is no gap between the decorative boards and the surface decoration is maintained even if the flocking is done over the entire surface. When flocking is done continuously, partially, and in a pattern, the joints appear frame-like, improving the design as well as the fire protection performance. That is, flame is prevented from passing through the joint.

(d) The noncombustible flocked layer is soft, has a heavy feel, and has a high design quality. It also gives a three-dimensional effect. Furthermore, by flocking the entire length of the butt end, it prevents sound and heat from passing through the joint, improving sound absorption and heat retention.
