Moreover, the base material which laminated | stacked glass mesh, glass cross, etc. on a woven fabric or a nonwoven fabric can be used. When the base material of the said range is used, since the contact interface with a plate-shaped hardening body becomes large, it is excellent in adhesiveness. Moreover, when it is applied to a wall surface etc., since a base material contains inorganic fiber, a plate-shaped hardened body can be supported stably. For this reason, the plate-shaped hardened | cured body at the time of a fire, the bending prevention property, and the fall prevention property are improved, and it is excellent in fire resistance and flameproof property. Moreover, since the said base material and the specific plate-shaped hardened | cured material are laminated | stacked, it can cut easily to arbitrary shapes at the time of construction, and small amount processing of a cut surface, etc. can also be performed suitably.

As the formwork to be used in the above (2), for example, formwork made of silicone resin, urethane resin, metal or the like or formwork having a release paper can be used. Moreover, as a method of laminating | stacking a base material, for example,

(I) a method of pouring a composition for a cured product into a die, drying and demolding to shape a plate-shaped cured product, and then laminating a substrate with an adhesive or the like,

(II) The composition for hardening bodies is poured into a die, and the method of laminating | stacking a base material, drying, and demolding, etc. before the composition for said plate-shaped hardening bodies is dried is mentioned.

Moreover, when pouring the composition for hardening bodies in said (I) and (II), the method similar to the lamination method in said (1) can be employ | adopted.

In said (1) and (2), the thickness of a plate-shaped hardened | cured material is 1.0 mm or more and 5.0 mm or less. In this case, since the uneven | corrugated pattern with a clear outline and a clear outline can be formed, the outstanding designability with a shading and a solid feeling can be obtained. In addition, the thickness of a plate-shaped hardening body removes a base material part.

In addition, as long as the effect of the present invention is not impaired, for example, a reinforcing material (ceramic paper, synthetic paper, glass cross, mesh, etc.) may be laminated, or an uneven shape may be formed or the decorative material may be sprayed for the purpose of enhancing decorative properties. . Examples of the decorative material include colored aggregates, mica, shellfish, plants, alumina pieces, glass pieces, metals, rubbers, plastics, and the like.

For example, in the case of manufacturing by the method (1), the formation of the uneven shape or the spraying of the decorative material can be carried out before the cured composition is cured, and the uneven shape is formed using a iron, relief, roller or the like. The method may be employed, and spraying of the decorative material may use known or commercially available sprayers. In the case of manufacturing by the method (2), the uneven shape can be given by adjusting the shape of the form inside because the form side becomes the surface of the plate-shaped hardened body, and when spraying the decorative material, it is well known or commercially available. After disperse | distributing a decorative material to the bottom surface in a form | work using the spreading | spreading machine etc. which are used, the composition for plate-shaped hardening bodies can be poured.

Moreover, as long as it is in the range which does not significantly inhibit the effect of this invention, you may laminate | stack a top coat layer for the purpose of improving the surface protection property etc. of a plate-shaped hardened | cured material. The top coat layer may be one having moisture permeability and transparency (clear layer). In this case, the designability (color) of the plate-shaped cured body can be used as it is, and the effects such as breathability and fire resistance can be further exhibited. Moreover, the top coat layer may be a color clear layer to which various pigments were added in the range which has transparency. Such a top coat layer can be formed by coating with a known aqueous or solvent paint. In this invention, the emulsion paint containing colloidal silica is preferable. In this case, surface strength, pollution resistance, etc. can be improved. In addition, by including colloidal silica, it is also effective in improving the fire resistance compared to the known top coat paint.

Examples of the emulsion containing colloidal silica include a mixture of a synthetic resin emulsion and colloidal silica, a colloidal silica composite emulsion in which the synthetic resin emulsion and colloidal silica are chemically bonded, and the like. It is preferable to use. It does not specifically limit as said synthetic resin emulsion, If it does not impair the effect of this invention, it can use suitably. In addition, the synthetic resin component and the colloidal silica in the emulsion including colloidal silica is preferably 95: 5 to 40:60 by weight ratio of solids. It is preferable that the particle diameter of colloidal silica is 10 nm-100 nm. In such a range, the surface protection property and fire resistance of a plate-shaped hardened body can be improved, without impairing the effect of this invention.

These coatings can use well-known coating methods, and coating mechanisms, such as a spray, a coater, a roller, and a brush, can be used.

The plate-shaped hardening body of this invention can be mainly used as a built-in building material of a building. That is, it can adhere to each part of the building interior surface, and can complete interior decoration. Specifically, it can be used for walls, partitions, doors, ceilings, etc. in houses, mansions, schools, hospitals, stores, offices, factories, warehouses, and restaurants. As a base material which comprises such a site | part, a gypsum board, a plywood, concrete, mortar, a tile, a fiber mixing cement board, a cement calcium silicate board, a slug cement pearlite board, etc. are mentioned, for example. These base materials may be those having an existing coating film on the surface thereof, or having wallpaper already adhered thereto. The plate-shaped hardening body of this invention is constructed so that a plate-shaped hardening body may face an indoor side with respect to such a base material.

Moreover, when constructing the plate-shaped hardening body of this invention, it can stick to a base | substrate using an adhesive agent, an adhesive, an adhesive tape, a nail, a tack. In addition, it can also be immobilized using a pin, a fastener, a rail or the like. Especially, it is preferable that the plate-shaped hardening body of this invention adheres to a base material using an adhesive agent.

It does not specifically limit as an adhesive agent, A well-known thing can be used. For example, the synthetic resin used for the adhesive material is not particularly limited, but may be an ethylene resin, a vinyl acetate resin, a polyester resin, an alkyd resin, a vinyl chloride resin, an epoxy resin, an acrylic resin, a urethane resin, a phenol resin, a melamine resin or an amino resin. , Polycarbonate resins, acrylic silicone resins, acrylic vinyl acetate resins, acrylic styrene resins, acrylic urethane resins, water-soluble types such as silicone resins, fluorine resins, and water-dispersion types, and the like, and one or two or more thereof can be used. have.

In addition, in order to impart various performances such as workability, finish, adhesive strength, and fire resistance, a powder component, hollow particles, porous particles, fibers, etc. may be added, or a coloring material, a sieving pigment, a dispersant, a viscosity modifier, an antifoaming agent, or a flavoring agent, as necessary. Additives normally used, such as a preservative and a preservative, can be added suitably.

When sticking a plate-shaped hardened | cured material with an adhesive agent, you may adhere | attach adjacent plate-shaped hardened bodies abutting, or may provide a joint between plate-shaped hardened bodies. When affixing so that it may contact, it is preferable to prevent an adhesive from protruding. In addition, in the case of providing a seam, the spacing at the time of sticking the plate-shaped cured body is not particularly limited, but may be about 1 mm to 30 mm. If it is this range, the interior finish utilizing the seam shape can be implemented. An adhesive can be exposed between plate-shaped hardening bodies, and a seam can be formed easily. Moreover, the adhesive of a seam part can also be smoothed with a spatula etc. as needed. Although the ambient temperature at the time of hardening an adhesive agent can be set suitably, it can carry out normally at normal temperature.
