Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an inorganic decorative board that is additionally installed on a wall surface or floor surface of a building and its additional structure.

(Prior Art) The inventors of the present invention have proposed Japanese Patent Publication No. 54-3704 (filed in August 1974).
(March 14th), we proposed a non-combustible inorganic decorative board which was made non-combustible by simultaneously applying a layer of surface decorative layer and embossing on the inorganic substrate layer. This inorganic decorative board comprises a surface decorative layer (specifically, a resin shielding layer and a surface resin layer thereabove, on an inorganic substrate layer composed mainly of aluminum hydroxide and containing a thermosetting resin). Non-flammable, which is obtained by laminating the surface resin layer itself or consisting of the pattern surface provided on the above-mentioned shielding layer), heat and pressure integrally at the same time when molding the embossed groove, and molding and curing. , Its excellent moldability and excellent appearance due to deep embossing have been well received, and it has come to be widely used as a decorative sheet for interior and exterior construction.

(Problems to be Solved by the Invention) Here, a procedure for additionally installing the above-mentioned nonflammable inorganic decorative board on a wall surface, a floor surface or the like will be outlined with reference to FIG. In the figure,
The inorganic decorative board P is attached to the surface W to be finished in an interconnected state through a suitable joint material (caulking agent, extruded aluminum material, etc .... shows caulking agent) S. This time,
Careful attention is paid so that the joint material S does not protrude to the surface of the inorganic decorative board P. As described above, the inorganic decorative board P has the inorganic substrate layer P ₁ and the surface decorative layer P ₂ integrated with each other by heat and pressure. Therefore, the side end face of the inorganic decorative board P ₁ has a layer structure of both layers P ₁ and P ₂ . Is exposed as it is, and the surface decorative layer P _{2 has} a layer thickness of 0.1 to 0.2 mm.
Therefore, depending on how the joint material S is filled,
As shown in the figure, a part of the end face of the substrate layer P ₁ may be exposed between the joint material S and the surface decorative layer P ₂ . Such joint material S
The filling state of # 1 significantly deteriorates the appearance of the construction surface, and since the jointing material S must be constructed so as not to protrude onto the surface of the decorative plate P as described above, the filling work of the jointing material S is It requires advanced skill and skill.

In the case where no joint material is used, even if there is a slight gap between the decorative plates P, P, the end face of the substrate layer P ₁ is exposed from this gap, and further, the decorative plate P due to small irregularities on the surface to be finished, Even if there is a slight step between P, the surface decorative layer P ₂
The end face of the base layer P ₁ was sometimes exposed due to the small thickness.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a novel inorganic decorative board and an attached structure thereof, which are free from the fear of causing the deterioration of the appearance as described above and can be installed extremely easily. Is.

(Means for Solving the Problems) The inorganic decorative board of the present invention and its accompanying structure for achieving the above object will be described with reference to the accompanying drawings. First
FIG. 1 is a vertical sectional view showing an example of an attachment structure using an inorganic decorative board of the present invention, FIGS. 2 to 6 are similar drawings of other embodiments, and FIG. 7 is a molding of a decorative board used in the present invention. It is explanatory drawing which shows the point.

That is, the inorganic decorative board of the present invention is formed by laminating the inorganic base layer 11 and the surface decorative layer 12 covering the surface of the base layer 11, and the back surface of the base layer 11 faces the surface to be finished. An inorganic decorative board 1 additionally provided, wherein the surface decorative layer 12 of the inorganic decorative board 1 wraps the side end surface of the inorganic base layer 11 but does not wrap the back surface and is integrally laminated. Characterize.

The first aspect of the attachment structure using the above-mentioned inorganic decorative board 1 is that the inorganic decorative board 1 is attached to the surface W to be finished, and the joint material 2 is provided between the adjacent inorganic decorative boards 1 and 1. It is characterized in that it is fitted so as to be in close contact with the surface decorative layers 12, 12 that enclose the side end faces.

Furthermore, in the second aspect of the attached structure, the inorganic decorative board 1 ...
Surface decorative layers 12, 12 that wrap the side edges of the adjacent decorative plates 1, 1.
It is characterized in that it is attached to the surface W to be finished so that they are in close contact with each other.

The non-combustible inorganic decorative plate according to the prior application is preferably adopted as the above-mentioned inorganic decorative plate 1, but other decorative plates are also excluded as long as the inorganic base layer 11 and the surface decorative layer 12 are laminated and integrated. Instead of this, for example, a paper or synthetic resin film in which a synthetic resin separately prepared in an inorganic material is impregnated may be laminated and integrated with an adhesive or the like to form an inorganic base layer and a surface decorative layer, respectively. The surface decorative layer 12 is an inorganic base layer.
In the case of stacking and integration with 11, the rear surface is covered with a dedicated mold K, K having a curved side peripheral portion as shown in FIG. 7, so that the side end portion wraps the side end surface 111 of the inorganic base layer 11. The curved portion is formed so as to face the portion. The side curve forming portion 121 of this surface decorative layer 12
Is preferably at least 1/3 or more of the total thickness of the decorative plate 1. If it is less than 1/3, the intended effect of the present invention is difficult to obtain. As described above, the surface decorative layer 12 is formed on the surface portion and the side end surface of the inorganic base layer 11, but is not formed on the back surface portion of the base layer 11. Since the back surface of the base layer 11 faces the surface to be finished, not only the surface decorative layer is not required, but also the backing layer is used for reinforcement.

The joint material 2 is a caulking agent that is filled between the decorative plates 1 and 1 after the decorative plate 1 is attached, and an E-shaped mold member formed of a light metal such as aluminum or a synthetic resin. In the process of attaching the decorative plate 1, the one that is held and fixed to the surface W to be finished in sequence while holding the end of the decorative plate 1 is adopted.

(Operation) The construction procedure of the attached structure using the inorganic decorative board 1 having the above-mentioned configuration will be described. The above-mentioned inorganic decorative plate 1 on the surface W to be finished
Is attached with an appropriate adhesive or fastener. When a caulking agent or the like is used as the joint material 2, the inorganic decorative plates 1 are all provided with a small gap, and then the joint material 2 is filled in each gap. Further, when the joint material 2 is the above-mentioned mold material, the joint material 2 is fixedly attached to the surface W to be finished while the inorganic decorative plates 1 are attached to the joint material 2 so that the end of the joint material 2 is held by the joint material 2. Done by Since the surface decorative layer 12 of the inorganic decorative board 1 is laminated and integrated so as to wrap the side end surface of the inorganic base layer 11, the caulking agent may have a small filling amount even if the filling amount is large or small. Even if there is a dimensional error, these joint materials 2 have a surface decorative layer 12 on the side end surface,
12, that is, the side end curve forming parts 121, 121 are closely packed, and therefore the side end faces 111, 111 of the inorganic base layers 11, 11 are not exposed.

In addition, in the attached structure of the second aspect, the inorganic decorative board 1
... is attached without a joint material, but the adjacent decorative plate 1,
The decorative layers 12, 12 on the side end surface of the first base layer 11 are closely contacted with each other, and the side end curved forming portions 121, 121 of the surface decorative layers 12, 12 on the side end surface are the side end surfaces 111, 111 of the inorganic base layer 11, 11. Since it is formed so as to wrap over 1/3 or more of the entire thickness, even if there is a slight step between the decorative plates 1 and 1 due to the unevenness of the surface W to be finished, the side end faces 111, 111 are visible. There is no.

(Example) Next, an example will be described.

(Example-1) FIG. 1 shows an example in which a silicone caulking agent as a joint material 2 is filled between the inorganic decorative plates 1 and 1 provided on the surface W to be finished with a vinyl acetate adhesive. The inorganic decorative board 1 of the illustrated example is mainly composed of an inorganic base layer 11 made of aluminum hydroxide as a main aggregate and containing a thermosetting resin such as a phenol resin or a melamine resin, and on the upper surface side of the base layer 11, A resin shielding layer 12a obtained by impregnating a paper or cloth with a thermosetting resin,
A pattern layer 12b in which a thermosetting resin such as a melamine resin is impregnated in a paper provided with a colored pattern is arranged in this order, and a shielding layer similar to the shielding layer 12a is provided on the back surface side of the base layer 11. 13
And the backing layer 14 in which paper is impregnated with a thermosetting resin such as melamine resin are arranged in this order, and the whole is arranged between the dies K of the pressing device shown in FIG. It is what Here, the resin shielding layer 12a and the pattern layer 12b constitute the surface decorative layer 12, and the thickness thereof is a thin layer of 0.1 to 0.2 mm.

The side edge curve forming portion 121 of the surface decorative layer 12 reaches about 1/2 of the thickness of the inorganic decorative plate 1 in the illustrated example, and the side end surface of the inorganic base layer 11 is exposed in the lower half thereof. It is not excluded that the side edge curved formation portions 121 are formed on both side end surfaces of the inorganic decorative board 1 and also formed on four sides. The caulking agent as the joint material 2 is formed in the side end curve forming portion 12 in the gap between the inorganic decorative boards 1 and 1 additionally provided.
It is filled closely with 1,121. Therefore, the side end faces 111, 111 of the inorganic base layers 11, 11 exposed in the lower half are hidden by this. Since the end face of the inorganic decorative board 1 is occupied by the side end curve forming portion 121 with a width of about 1/2 of the surface, the side end face 111 of the inorganic base layer 11 is exposed even if the filling amount of the caulking agent is small. Without the need for skillful finishing, the joint finish is beautiful and simple.

Here, constituent materials of the inorganic base layer 11 and the like will be described.

[1] Material of the inorganic base layer 11 Main aggregate: Aluminum hydroxide Al ₂ O ₃ · 3H ₂ O solid powder is used.

Auxiliary aggregates: calcium carbonate, silica sand, calcite powder, calcium silicate, zeolite, kaolin, bentonite, acid clay, etc. are used.

Reinforcement materials: mineral fibers (asbestos, etc.), inorganic fibers (glass fibers, ceramics wires), metal fibers (iron fibers, aluminum fibers, whiskers, etc.), natural fibers (cotton, linen, etc.), synthetic fibers (vinylon, Nylon, Tetron, etc.) fiber chops are used.

Binder: Phenol / formalin condensate and its derivative, urea, melamine / formalin condensate and its derivative, resin such as polydiphenyl oxide resin and its derivative are used.

The aluminum hydroxide powder serves as a mechanical strength material for the base layer, and is compounded at 40 to 97% (weight ratio, preferably 50 to 85% by weight) with respect to the total amount, and the molding temperature is 200 ° C.
Although the heat does not change below, when the ambient temperature reaches 300 to 500 ° C, the water of crystallization is released and the combustion is suppressed, and at the same time it becomes Al ₂ O ₃ as a heat-resistant material. give. If the blending amount is less than 40%, it becomes insufficient to obtain quasi-incombustibility, and conversely, if it exceeds 97%, the binding force decreases, and the above range of 50 to 85% is a desirable range.

Auxiliary aggregates are used to improve the mechanical strength of the molded product, reduce the cost by increasing the amount, or as an auxiliary binder and to add and increase the fluidity at the time of molding. On the other hand, it is 77% or less, and if it exceeds 77%, the incombustibility is impaired, and 15 to 45% is a desirable range.

Reinforcing agents are used to further improve the mechanical strength of the moldings and are added up to 15%, preferably 2-10%.

The binder is a flame-retardant thermosetting resin that imparts molding fluidity to each other and can be cured by heat and pressure, and the amount used is 3 to 12%. If the amount is less than 3%, the binding strength will be insufficient, and conversely, if it exceeds 12%, even if the amount of aluminum hydroxide is increased, it cannot become a noncombustible material. It is preferably 6 to 10%.

[2] Material for Resin Shielding Layers 12a, 13 Ordinary pulp paper or cloth impregnated with the same thermosetting resin as described above or a thermoplastic resin solution such as vinyl acetate-vinyl chloride or acrylic acid emulsion is used.
The resin shielding layers 12a and 13 are for preventing exudation of the thermosetting resin in the base layer 11 during the thermocompression molding, and particularly the shielding layers.
This is effective in preventing unevenness of exudation on the pattern layer 12b arranged on the 12a.

[3] Material of Pattern Layer 12b The pattern layer 12b is a paper base material on which a desired coloring or picture pattern is printed impregnated with a thermosetting resin, or is colored during impregnation papermaking.

Paper base material: Various composite papers and cloths are used. The composite paper / cloth includes paper / cloth (including non-woven fabric) obtained by mixing cellulose pulp fibers and synthetic fibers, paper / cloth obtained by mixing cellulose pulp fibers with synthetic fibers and inorganic fibers, and further cellulose pulp paper. Synthetic fiber paper / cloth or inorganic fiber paper / cloth, which is laminated and integrated with an adhesive or an impregnating resin described later, is used.

Impregnating resin: A transparent or translucent thermosetting resin liquid such as urea, melamine, diallyl phthalate, acrylic acid or methacrylic acid ester and its derivative resin is impregnated and dried in the composite paper.

[4] Material of the backing layer 14 The backing layer 14 is for preventing warpage and bending of the panel, and is made integral with the thermosetting resin by impregnating kraft paper with thermosetting resin.

[5] Others It is also possible to provide an overlay layer (not shown) on this surface in order to protect the pattern layer 12b. The overlay layer is formed by integrally fixing a transparent resin film such as urea or melamine or a fluororesin film on the upper surface of the pattern layer 12b during the thermocompression bonding. In particular, the fluororesin film is
Since it has excellent stain resistance, it is suitable for use in the walls of bathrooms and kitchens, and a film in which a polyvinylidene fluoride film and a methyl methacrylate film are combined into a composite (for example, KFC film manufactured by Kureha Chemical Industry Co., Ltd.) Market available and preferably adopted. A pattern can be printed on such an overlay layer, and in this case, the pattern layer 12b can be omitted.

(Example-2) The example shown in FIG. 2 shows an example in which an extruded aluminum material is used as the joint material 2. The joint material 2 includes a mounting substrate 21 and a joint plate 22, and the mounting substrate is attached to the surface W to be finished.
Then, the inorganic decorative plate 1 is attached so that its side end is received between the mounting substrate 21 and the joint plate 22. At this time, the edge portion of the joint plate 22 is in close contact with the side edge curve forming portions 121, 121 of the surface decorative layers 12, 12 which are opposed to each other, and therefore, even if the joint material 2 has a size or a molding error, the inorganic material The side edges of the decorative base plate 1 are hidden and the side edges of the inorganic base layers 11 and 11 are hidden.
111 and 111 are never exposed.

(Example-3) FIGS. 3 (a), (b) and (c) show the back surface of the inorganic decorative plate 1 having a concave curved surface 15 such as a corrugated shape. Such a concave curved surface 15
It is possible to increase the attachment strength with an adhesive or the like, and at the same time, it is possible to reduce the cost and weight by reducing the materials used without lowering the strength of the decorative board itself. Combined with the simplification of the additional construction by material 2, efficient finishing construction is promised.

(Embodiment 4) In the embodiment shown in FIG. 4, a plate material 3 of wood or synthetic resin is attached to the back surface of the inorganic decorative board 1, and one end portion of the plate material is extended to form a gap forming portion 31.

In this case, by attaching the gap forming portion 31 by nailing together with the ease of filling the joint material 2, the decorative plate 1
It becomes extremely easy to install it.

(Example-5) The example shown in FIG. 5 shows an example in which the inorganic decorative boards 1 are closely attached to each other without a joint material. In the illustrated example, vinyl acetate or a rubber adhesive 4 is applied to a surface W to be finished such as concrete in a thickness of 3 to 5 mm, and the same inorganic decorative board 1 as in FIG. The layers 12 are fixed and integrated on the adhesive 4 so that they are in close contact with each other. In this case, since the side edge curve forming portions 121, 121 of the surface decorative layers 12, 12 of the adjacent decorative plates 1, 1 are in close contact with each other,
The side end faces 111, 111 of the base layers 11, 11 are not visible. In this case, even if a slight gap is generated between the adjacent decorative plates 1 or 1, or even if a slight step is generated between the adjacent decorative plates 1 or 1 due to the small unevenness of the surface W to be finished, the side edge curve is generated. Since the forming portions 121, 121 are formed so as to surround the end faces of the base layers 11, 11, the side end faces 111, 111 are not visible. Further, by applying the adhesive 4 thickly, the surface of the inorganic decorative board 1 can be made flush even if the concrete surface W to be finished has small irregularities.
Also waterproof. When more complete waterproofness is required, it is desirable to lay a waterproof sheet (not shown) or the like on the surface W to be finished and then perform the above attachment.
