In order to make up the interior and exterior of concrete walls of buildings, spray coating with an emulsion paint is often performed.
Spray coating has drawbacks in that mist is generated, the working environment is poor, coating unevenness is likely to occur near the scaffold, and it takes a long time to cure the coating film. Also, spray painting cannot easily provide a picture, and it is difficult to decorate the interior or exterior with a beautiful design. Therefore, instead of spraying, a painted concrete plate having a decorative sheet, particularly a decorative sheet with a pattern, stuck on its surface has been used in many cases. Generally, a concrete board having a picture is manufactured by attaching a decorative sheet to the surface of a preformed concrete board using an adhesive. However, such a manufacturing method is not efficient, and the surface smoothness of the decorative concrete plate, the adhesion between the decorative sheet and the concrete, and the durability thereof are not sufficiently satisfactory.

As shown in FIG. 3, in the method for manufacturing a decorative concrete plate of the present invention, a plastic layer (32), a pattern printing layer (33), and a protective layer (34) are formed in this order on the surface of a fibrous sheet (31). Then, a decorative sheet (3) coated with an adhesive (2) having an adhesive force to concrete on the back surface is prepared.
As shown in the figure, this decorative sheet is laid on a flat base (not shown) with the adhesive side up, and a formwork (4) defining the periphery of the decorative concrete plate is placed on the decorative sheet. Then, the mortar (1) is poured into the mold and hardened, and then the mold is removed to obtain a decorative concrete plate as shown in FIG. The mortar used in the present invention is the same as the conventional one, that is, kneaded with water after adding various admixtures or additives to portland cement and river sand as required. The adhesive may be appropriately selected from known adhesives in consideration of the adhesive strength to concrete and the material of the decorative sheet. For example, if the back of the decorative sheet is a fibrous sheet, chloroprene solvent-based, vinyl acetate solvent-based, organic solvent-based adhesives such as vinyl chloride copolymer solvent-based, vinyl acetate emulsion-based,
An emulsion adhesive such as a synthetic rubber emulsion or a polyurethane adhesive can be used. In particular,
Those which are non-adhesive when applied and dried, such as emulsion-based adhesives, and which are activated by the moisture in the mortar, are easy to use and have a strong adhesive force and are useful. As the decorative sheet, a layer obtained by laminating a plastic layer, a pattern printing layer, and a protective layer on a fibrous sheet, if desired, and then embossing as desired can be used.

According to the production method of the present invention, since the mortar is formed on the decorative sheet to which the adhesive is applied, the decorative sheet can be attached to the concrete plate simultaneously with the molding.

A decorative sheet for an exterior material having the structure shown in FIG. 3 was prepared.
This decorative sheet uses, as a fibrous sheet (31), a vinylon nonwoven fabric (manufactured by Kojin Sylbo) weighing 50 g / m 2 containing glass fibers, and an acrylic emulsion “solid” as a plastic layer (32) on one surface. Apply "Wall 3200" (Sunstar Giken), print the pattern (33) with the weather-resistant ink "VMC" (Moroboshi Ink), and protect it with a fluororesin paint "Lumiflon 302C" (Asahi Glass) to a thickness of 10μ. A layer (34) is formed. Apply the adhesive “Penguin Cement 1000” (manufactured by Sunstar Chemicals) to the other surface of the nonwoven fabric of the above decorative sheet, lay it on the floor with its surface facing up, and place a wooden formwork (with an inner glue length of 33 cm) on it , Width 33 cm, depth 5 cm). Then,
Portland cement 35% (weight), river sand 54% and water
Mortar consisting of 11% was poured into a mold and allowed to stand. After the mortar was hardened, the mold was removed to obtain a decorative concrete plate shown in FIG. In the figure, (1A) shows a concrete plate.
