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 noncombustible 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 pasting a pattern-printed decorative paper, decorative cloth, synthetic resin sheet, etc. I was wearing it. 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, heat absorbing and heat retaining 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.

Furthermore, when the substrate is a fiberboard, although the fiberboard itself has heat absorbing properties, the surface is covered with a decorative surface, which ultimately reduces the heat absorbing effect.

Furthermore, in order to maintain the heat absorbing effect, a large number of small holes are sometimes 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. do.

Therefore, the following proposals have been made to address these problems.

Nylon with a length of 0.5 to 5 mm on the entire surface of the gypsum board or in the shape of a predetermined pattern,
Flocked gypsum board made of organic or inorganic fibers such as cotton wool and glass fiber
No. 94612) Apply epoxy resin adhesive paint to the surface of a unit frame flat plate made of concrete, especially lightweight cellular concrete, flock various types of single fibers on the top surface, and apply epoxy resin adhesive paint to the top surface of the flocked flat plate. Concrete spray-coated with paint, especially lightweight aerated concrete decorative board (Special Publication No. 48-34930) By the way, the former uses fiber flocking to achieve a finish that cannot be obtained with conventional decorative paper pasting etc. It became possible to obtain unique surface designs.

However, in this type of decorative board, the fixing strength of the flocked fibers to the substrate is weak, and during use, the fibers may fall off, spoiling the appearance of the decorative board itself and its surroundings. Further, the scattering of the fallen fibers into the space is not sanitary for the human body.

Regarding the latter, the abrasion resistance and durability of the flocked organic fibers are increased, and the fibers are also fixed to the flat plate with high strength. However, according to this technique, the fibers to be flocked are arranged in a sandwich pattern between the paint on the surface of the flat plate and the paint coated from the top of the fibers, so the fibers to be flocked are not exposed to the surface of the decorative board. Become. For this reason, the flocked fibers have the problem of completely losing the flocked properties such as heat retention, insulation, and sound absorption that can be obtained by exposing the flocked fibers to the surface.

It is an object of the present invention to solve the problems of conventional decorative boards of this type.

That is, the present invention electrostatically flocks noncombustible piles onto a noncombustible plate-like substrate, and then coats the piles without burying them, thereby achieving noncombustibility, soundproofing, heat retention, heat insulation, and sound absorption properties. The present invention aims to provide a decorative board with a high design quality that does not cause the pile to fall off while bringing out the flocked characteristics.

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. Noncombustible substrates 1 include asbestos cement boards, calcium silicate boards, wood chip cement boards, gypsum boards, calcium carbonate boards, ALC boards, metal boards, and inorganic fibers such as rock wool, asbestos, mineral wool, glass fibers, and carbon fibers. A fiberboard consisting of is 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,
As the adhesive 2, a transparent adhesive, an adhesive that becomes transparent after curing, a translucent adhesive, or an opaque adhesive may be used depending on the purpose.

The adhesive 2 is applied using a spreader roll coater, a screen printer, etc. after gravure printing.

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

In addition, sealing treatment, sealer treatment, undercoating, intermediate coating, etc. are applied as necessary to the end of the board, the end of the actual processing, and the chamfered portion.

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 non-flammable pile P is densely flocked onto the applied adhesive 2 using an ordinary electrostatic flocking device. The hair is transplanted in a pattern over the entire surface or partially.

As the noncombustible pile P, fibers such as glass fiber, carbon fiber, asbestos, rock wool, and mineral wool are used.

Each of these noncombustible piles P has excellent wear resistance and strength, so when they become flocked and are exposed on the surface, they form a single flocked layer on the surface of the decorative board. The surface itself is improved in terms of strength such as abrasion resistance and durability, and at the same time it also provides water repellency.

Furthermore, since the pile is exposed in a flocked state, flocked flocking properties such as heat retention, heat insulation, and sound absorption properties inherent to flocking can be generated.

Further, electrodeposition treatment is performed as necessary. The noncombustible pile P is selected depending on the surface design requiring transparent pile, opaque pile, translucent pile, or opaque pile.

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, piles P ₁ and P ₂ are all opaque piles.
However, it is also possible to partially use transparent piles so that the decorative surface on the substrate 1 can be seen through.

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

(3) Then, apply top coat 3 without filling the pile P.

By applying the top coat 3 in this way, the pile P can be firmly fixed to the substrate without losing the flocked characteristics such as heat retention, heat insulation, and sound absorption of the flocked pile. It is possible to prevent it from falling off.

(Aspects of implementation) The following examples can be considered as aspects of implementation.

Nonflammable substrate 1 → Apply inorganic adhesive 2 to the entire surface →
Electrostatic flocking of non-flammable short fibers or long fibers Non-flammable substrate 1 → ground treatment → applying adhesive 2 in a pattern → electrostatic flocking of non-flammable pile Non-flammable substrate 1 → ground treatment → pattern printing 4 → adhesive 2 Apply in a pattern → Electrostatically flock in a pattern to form flocking pattern 5. (Fig. 3) Nonflammable substrate 1 → Apply adhesive 2 in a pattern → Electrostatically flock short fibers P ₁ to form a low pattern 6 → Apply adhesive 2 in a pattern → Static fibers P ₂ Electro-flocking to form a tall pattern 7 (Figure 4) Non-combustible substrate 1 → Apply adhesive to the entire surface → Mix long and short fibers electrostatic flocking The non-flammable piles flocked in ~ are given a topcoat without being buried. .

(Actions and Effects of the Present Invention) Since the noncombustible pile P is flocked on the surface of the noncombustible substrate 1, a completely noncombustible decorative board can be obtained. In addition, the manufacturing method only requires two steps: applying adhesive and flocking, so productivity is high.

The non-combustible flocked layer is soft, has a heavy feel, has a three-dimensional effect, and has a high design value. Furthermore, if the flocked layer is provided on the entire surface or close to the entire surface, sound absorption and heat retention properties will also be improved.

After the non-combustible pile is flocked, a top coat is applied without filling the pile, so the flocked properties such as heat retention, insulation and sound absorption, and the decorative board surface obtained by the flocked layer of the non-combustible pile. The pile can be firmly fixed to the substrate without losing its various advantages, such as increased strength such as abrasion resistance and durability, water repellency, and the surface design of the pile. It is possible to prevent the sheet from falling off the substrate, and it is possible to obtain a decorative board that is excellent not only in surface strength but also in terms of aesthetics and hygiene.
