Abstract

PURPOSE:To produce a low-cost decorative body functioning as a decorative sheet with a rich sense of beauty, preventing a peeling accident, and having a rust proof effect and a waterproof effect by a method wherein a polymer cement mortar mixed with natural stone is applied to a base body, and a surface layer is removed after the mortar is half or completely cured so that the natural stone is exposed. CONSTITUTION:Granular natural stone 10 is kneaded with a polymer cement mortar in the amount of approximately 0.3 pts.wt. per 1 pts.wt. of the polymer cement mortar. A black pigment is further added in the amount of approximately 0.0002 pts.wt. and kneaded. The obtained material is a coating material 12. The coating material 12 is applied to a steel material 11 by a trowel, dried, and cured. After the coating material 12 is sufficiently dried and cured, the surface is smoothed by using a disk grinder, a belt sander, or the like. Furthermore, the surface is made glossy using sandpaper, a grinding wheel, or the like while being wet by water. Thus, a decorative sheet A is obtained. In addition, since the surface has a semigloss in this state, a coating material, such as a clear lacquer, is applied if a higher glossiness is required.

【Example】

(Example 1) This example shows a case where the base body is applied to the outer wall, the inner wall, the decorative plate, the frame material such as the lintel cubic, the eaves, the parapet, etc., by applying the method for manufacturing a decorative body according to the present invention.

Hereinafter, the method for producing a cosmetic body according to the present invention will be specifically described with reference to the embodiments shown in the accompanying drawings, FIG. 1 (a) to FIG. 1 (e). In this example, a decorative plate is used as the decorative body.

First, as shown in FIG. 1 (a), the particle size is 3 to
Prepare natural stone 10 consisting of 10 mm granular granite.
Note that the granular natural stone 10 can be used by collecting granular natural stone as a scrap material generated in a quarry of marble or granite.

The granular natural stone 10 can also be obtained by crushing small massive natural stones using a ball mill or the like.

On the other hand, as shown in FIG. 1 (b), a steel plate 11 as a base is prepared.

Next, 0.3 parts by weight of the above-mentioned natural granule 10 was kneaded with 1 part by weight of the polymer cement mortar having the following composition and blending ratio, and a black pigment was further added.
0.0002 parts by weight was added and kneaded to obtain a coating material 12.

This coating material 12 is, as shown in FIG. 1 (c),
The steel plate 11 was painted with a trowel and dried and cured.

After the coating material 12 is sufficiently dried and cured, FIG.
As shown in (d), the surface was smoothed using a disc grinder, a belt sander or the like, and further, while being wet with water, gloss was imparted using paper or a grindstone to obtain a decorative sheet A. In this situation, since it is in a semi-glossy state, it is preferable to apply a paint such as clear lacquer when further gloss is required.

The appearance of the decorative board A thus obtained is the same as that of granite as an integrated piece cut out from the quarry, and it is rich in aesthetics. Since the cement mortar has a sufficient adhesive force, the granular natural stone 10 is strongly integrated with the steel plate 11, and the peeling accident can be reliably prevented.

Furthermore, since natural granular stones can be used as end material generated as a by-product in the quarry, the decorative board A can be manufactured at an extremely low cost.

Then, for example, the above-mentioned decorative board A is coated with a desired adhesive 13 (polymer cement or the like) as shown in FIG.
As shown in (e), by sticking to the outer wall 14 of the building, the aesthetics of the building can be improved.

Although black pigments are used as pigments in the above-mentioned examples, other pigments of arbitrary colors can be mixed, and the type of pigment is not limited to one. It is also possible to use pigments of different colors. In addition, there is no pigment at all
Can also be manufactured.

As the polymer cement mortar used in the above-mentioned method for manufacturing a decorative board, for example, a main material containing silicon oxide, calcium oxide and iron oxide as a main component and at least an acrylic ester copolymer as a main component are used. What was produced by mixing the following composite polymer emulsion can be used, and the specific components and blending ratios are shown below.

In this embodiment, as the polymer cement,
It is prepared by mixing the composite polymer emulsion P having the following composition and the main agent M.

(Composite Polymer Emulsion P) (Example 1) (Example 2) The component weight ratio of the white cement was as follows.

[0028] Further, instead of the above-mentioned main agent M, mortar in which sand and cement are mixed can be used.

Then, the composite polymer emulsion P was placed in a stirring container and stirred with a hand mixer while gradually adding the main agent M to produce polymer cement.

The compounding ratio of the polymer cement is preferably 3 to 6 parts by weight of the main agent M with respect to 1 part by weight of the composite polymer emulsion P. In this example,
It was 1: 4.

(Embodiment 2) In this embodiment, the base body is a bridge girder, a main pillar, a balustrade, a pillar, a chord member, a diagonal member, a guardrail and its pillar, a floor lower surface, a soundproof wall, a tunnel, a dam levee, and This is a case where the manufacturing method of the decorative body according to the present invention is applied to the accessory, road surface, steel pipe pile, pipe bridge, pipe line, retaining wall, and the like.

In this embodiment, the main pillar B of the bridge
The case where the manufacturing method of the cosmetic body according to the present invention is applied to the column C and the column C.

That is, also in the case of this embodiment, as in the above-mentioned embodiment, as shown in FIG. 2 (a), the natural stone 10 in the form of granules is kneaded in the mortar by using the mortar gun 30. The applied coating material 12 was sprayed on the surfaces of the main pillar B and the balustrade C, and dried and cured.

After the coating material 12 is sufficiently dried and cured, FIG.
As shown in (b), a part of the mortar was removed using a disc grinder 31 to obtain a main pillar B and a balustrade C from which the granular natural stone 10 was projected. The appearance of the main pillar B and the balustrade C thus obtained is the same as that of granite as an integrated body cut out from the quarry, and it is rich in aesthetics. Cement mortar has sufficient adhesive strength, so granular natural stone 10 is a steel plate.
It is strongly integrated with 11 and can reliably prevent peeling accidents.

In the above-mentioned Examples 1 and 2, the coating method was spraying. However, by changing the compounding ratio of the polymer emulsion P and the main agent M, a method such as iron coating, brush coating, dipping, etc. You can also do

[0036]

As described above, in the method for producing a cosmetic body according to the present invention, a polymer cement mortar mixed with granular natural stone is applied to a substrate, and after the mortar is semi-cured or completely cured, at least the same. The surface layer of the mortar is removed to expose the natural stone to the outside, and the natural stone is adhered to the substrate to manufacture.

The appearance of the decorative body obtained by the above-mentioned manufacturing method is the same as natural stone as an integrated body cut out from a quarry, and it has a beautiful aesthetic effect, and it sufficiently fulfills the function as a decorative board and is made of a polymer. Cement mortar has sufficient adhesive strength, so the granular natural stone is strongly integrated with the substrate, and it is possible to reliably prevent peeling accidents.
It also has a rustproof effect and a waterproof effect. Furthermore, since natural granular stones can be used as the end material generated as a by-product in the quarry, the cosmetic body can be manufactured at an extremely low cost.

That is, granular natural stones such as granite and cold water stone are used without using expensive natural stones as one body,
It is mixed with polymer cement mortar, which has excellent adhesive strength, waterproof performance, and water resistance, and it is applied, so it can be applied freely even to curved substrates and washed out.
Finishing with a method such as sharpening, tapping, blasting, high pressure water washing, etc. is cheaper than using a unitary piece of natural stone, but can give a finish that is comparable in appearance.
