Description

The present invention relates to a functional panel provided with a diatomaceous earth-containing layer and a method for producing the functional panel.

Diatomaceous earth is known to have an absorption / discharge effect and a deodorizing / deodorizing effect, and has long been used as a surface layer material on indoor walls. Since diatomaceous earth collapses when it dries, it is used as a plastering wall by kneading lime, cement, clay, synthetic resin, fiber material, etc.

When used as a plastering wall, it is generally applied on a rigid and hydrophilic base such as rough wall or gypsum board. The plastering wall is coated in an uneven shape with a thickness of about 2 mm and 0.5 mm to 1 mm so that moisture in the air is absorbed and discharged to exert a deodorizing and deodorizing effect.

By using diatomaceous earth as a plastering wall, effects such as moisture absorption and discharge, deodorization and deodorization can be obtained, but when diatomaceous earth is used as a plastering wall, there is a drawback that the cost increases.

In order to solve this difficulty, wallpaper coated with diatomaceous earth has been proposed, but since a binder such as synthetic glue is used for this type of wallpaper to prevent the diatomaceous earth from peeling off, the binder uses diatomaceous earth. The holes may be blocked and the suction and discharge may be hindered.

In recent years, in addition to wallpaper, a panel (Patent Document 1) having a diatomaceous earth-containing layer as a base material has been proposed. In such a panel, a base material such as paper is attached to a base material, and a diatomaceous earth-containing material is coated on the base material.

Utility Model Registration No. 3132595

However, the panel manufactured by the conventional manufacturing method has a problem that the base material swells when placed in a high humidity environment, and the diatomaceous earth-containing material on the base material is easily peeled off from the base material.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a functional panel in which diatomaceous earth does not easily peel off and a method for manufacturing the functional panel.

[Functional panel]
The functional panel of the present invention has an adhesive layer on the surface of the base material, a diatomaceous earth-containing layer on the surface of the adhesive layer, and the adhesive layer and the diatomaceous earth-containing layer are bonded by the anchoring effect of both layers. The periphery of the base material may or may not be surrounded by a frame. Here, the adhesive layer may be any one that can be bonded to the diatomaceous earth-containing layer by the anchoring effect when the moisture of the diatomaceous earth-containing layer is removed, and may be an adhesive, or a tape provided with an adhesive or an adhesive. Good (same below).

[Manufacturing method of functional panel]
In the method for producing a functional panel of the present invention, an adhesive layer is provided on the surface of a base material surrounded by a frame, and a diatomaceous earth-containing material in the form of a sol or gel on the surface of the adhesive layer and inside the frame. Is applied to form a diatomaceous earth-containing layer, the water contained in the diatomaceous earth-containing layer is evaporated, and both layers are bonded by the anchoring effect of the adhesive layer and the diatomaceous earth-containing layer. The frame can be removed from the substrate after the diatomaceous earth-containing layer has been applied or dried, or can be attached as it is.

[Functional panel]
The functional panel of the present invention has the following effects.
(1) Since the adhesive layer and the diatomaceous earth-containing layer are bonded by the anchoring effect of both layers, the diatomaceous earth-containing layer is less likely to peel off due to deterioration over time. Even if the base material is non-hydrophilic, the diatomaceous earth-containing layer is difficult to peel off.
(2) By hanging or suspending the functional panel of the present invention on the wall surface or partition of the room, it is possible to purify the indoor air and adjust the indoor humidity, so that the effect of improving the indoor environment can be expected. ..
(3) When there is a frame around the base material, it can be used for interior decoration by hanging or hanging it on a wall partition or the like, as in the case of decorating a framed item in the room.

[Manufacturing method of functional panel]
The method for manufacturing a functional panel of the present invention has the following effects.
(1) Since the adhesive layer and the diatomaceous earth-containing layer are bonded by the anchoring effect of both layers, the diatomaceous earth-containing layer is less likely to peel off.
(2) Since the size and shape of the base material can be selected according to the application of the functional panel and the adhesive layer and the diatomaceous earth-containing layer can be provided in this order, the diatomaceous earth is applied on the wall soil applied to the wall. Unlike this case, a large amount of diatomaceous earth is not required, and the diatomaceous earth-containing layer can be easily applied.
(3) If the adhesive layer and the diatomaceous earth-containing layer are applied to the inside of the frame provided on the outer periphery of the base material, even if the adhesive layer and the diatomaceous earth-containing layer are thickly piled up (even if applied), the adhesive layer also contains diatomaceous earth. The layers are also hard to fall out of the frame.

Explanatory drawing which shows an example of the functional panel of this invention. The perspective view of the partial excision of the functional panel of this invention. (A) and (b) are the functional panels of the present invention, and are partial cross-sectional views when the base materials are different, and (c) is a partial cross-sectional view in a state where the frame material is opened.

(Embodiment of Functional Panel)
An example of the functional panel of the present invention will be described with reference to the drawings. The functional panel 1 shown in FIGS. 1 and 2 has an adhesive layer 3 on the upper surface of a rectangular base material 2, and a diatomaceous earth-containing layer 4 on the adhesive layer 3. There is a frame 5 on the outer circumference of the base material 2.

The base material 2 is the base of the functional panel of the present invention, and is a non-hydrophilic member such as a styrofoam plate, an aluminum plate, or an aluminum composite plate. The illustrated base material 2 is a rectangular flat plate material and has a smooth upper surface, but the base material 2 can have an arbitrary shape such as a triangle or a heart shape, and the size can be designed according to the application. The surface may be uneven or smooth.

The adhesive layer 3 is an adhesive, and is easily adhered to or bonded to the base material 2. The thickness is arbitrary, but a few μm to several mm is suitable. The surface may be smooth or uneven.

The diatomaceous earth-containing layer 4 contains at least diatomaceous earth, and for example, a mixture of diatomaceous earth, clay (including paper clay), a fiber material, an adhesive, a binder, and the like is suitable. As the fiber material, hemp, other natural fibers, chemical fibers and the like are suitable. A general-purpose binder such as starch or chemically synthesized glue can be used as the binder. The thickness of the diatomaceous earth-containing layer 4 is several mm, preferably 2 to 3 mm, which is thicker than that of the adhesive layer 3. The surface of the diatomaceous earth-containing layer 4 may be a rough surface, an uneven surface, or a smooth surface, but it is desirable to make the surface surface rough or uneven to increase the surface area.

The adhesive layer 3 and the diatomaceous earth-containing layer 4 are bonded to each other by an anchoring effect. The anchoring effect is exhibited by pouring a diatomaceous earth-containing material containing water onto the surface of the adhesive layer 3 and then evaporating the water contained in the diatomaceous earth-containing material.

The frame 5 surrounds the outer circumference of the base material 2. The frame 5 has a rectangular frame shape in which the corners of the four frame members 6 are connected by a joint 7. As the frame material 6, a material such as aluminum, aluminum composite material, wood, or resin can be used. An annular hanger 8 through which a string or the like is passed is attached to each joint 7.

Each frame member 6 has a U-shape in cross section, and can be covered only with the base material 2 and the adhesive layer 3 as shown in FIG. 3 (a), or the diatomaceous earth-containing layer 4 as shown in FIG. 3 (b). It can also be placed on top of it. It is more difficult to remove from the base material 2 when the diatomaceous earth-containing layer 4 is covered as shown in FIG. 3 (b).

The frame 5 may have a fixed frame shape, but each frame material 6 can be rotated in the arrow ab direction as shown in FIG. 3C, and when rotated in the b direction, the base material 2 or the diatomaceous earth-containing layer can be rotated. When it is removed from the top of 4 and rotated in the a direction, it can be placed on the base material 2 or the diatomaceous earth-containing layer 4.

(Embodiment of Manufacturing Method of Functional Panel)
In the method for producing a functional panel containing diatomaceous earth of the present invention, a frame 5 is attached around a base material 2, an adhesive layer 3 such as an adhesive or an adhesive is provided inside the frame 5, and a gel-like adhesive layer 3 is provided on the frame 5. The diatomaceous earth-containing material is placed and leveled with a spatula, roller, iron or the like to form the diatomaceous earth-containing layer 4. If possible, a sol-like diatomaceous earth-containing material may be put on the adhesive layer 3 and inside the frame 5 to form the diatomaceous earth-containing layer 4. The water contained in the diatomaceous earth-containing layer 4 is evaporated by natural drying or forced drying, and the adhesive layer 3 and the diatomaceous earth-containing layer 4 are bonded by the anchoring effect of both layers. The diatomaceous earth-containing material may be provided so as to enter the space between the surface of the base material 2 and the frame 5.

The frame 5 can prevent the diatomaceous earth-containing material from spilling out of the base material 2 when the gel-like diatomaceous earth-containing material is placed, and when the sol-like diatomaceous earth-containing material is charged, the diatomaceous earth-containing material is used. It is desirable that the thickness is such that it can be prevented from flowing out of the base material 2.

The diatomaceous earth-containing material may penetrate to the inside of the frame 5 as shown in FIG. 3 (b). In this case, the functional panel is more robust than when it is not inserted.

The material, structure, etc. of the frame can be arbitrary. The frame 5 may be removed after the diatomaceous earth-containing layer 4 is provided, and may be left attached. It can also be used as a decorative forehead by leaving it attached. The frame 5 can be attached after the adhesive layer 3 and the diatomaceous earth-containing layer 4 are provided. The frame 5 in this case is mainly for decoration.

The frame 5 may have a back plate (not shown) on the inner back surface thereof. In this case, the base material 2 may be stacked on the back plate, and the back plate may be used as the base material 2.

[Action]
The diatomaceous earth-containing material on the adhesive layer 3 is in a state of being separated from the adhesive layer 3 by a water film of water contained in the diatomaceous earth-containing material for a while after being placed on the adhesive layer 3, but with the passage of time. When the water contained in the diatomaceous earth-containing material evaporates, an anchoring effect is exhibited, and the anchoring force causes the adhesive layer 3 and the diatomaceous earth-containing material to bond with each other, making it difficult to peel off.

The functional panel 1 of the present invention can be used for various purposes such as being hung on a wall in a room or being installed in a barn or a piggery.
