Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative finish of walls and floors of houses and other buildings and structures.

[0002]

2. Description of the Related Art Conventionally, for the finishing of interior and exterior materials of buildings, spraying of color cement mortar, resin mortar, etc., or a decorative material that forms a pattern on the finished surface using pattern paper, masking tape etc. at the time of ironing Many finishing methods are used, and specifically, tile-like spraying using a resin such as cement mortar or MMA is performed. This finishing method has the advantage that a uniform pattern can be reproduced without limit.

[0003]

However, the finished surface obtained by the above-mentioned technique can only make a certain pattern because the pattern paper and the masking tape are used. Further, since the adhesive tape adheres to the substrate, problems such as floating and peeling occur.

Further, in the case of a beautifully finished finish that gives unevenness, since a method by spraying is generally used, it needs to be cured. In that case, the pattern paper and masking tape cannot be used. Further, even when the color tone of the finishing material is changed to form a colorful pattern, there is a problem that the use of a paper pattern or the like requires curing other than the coated surface, and the more color tones, the more troublesome.

An object of the present invention is to solve the above-mentioned problems and to provide a method capable of easily applying a complicated pattern or painting requiring curing.

[0006]

In order to solve the above-mentioned problems, a peelable plastic layer is formed by spraying or brush-coating a peelable plastic on the wall of an arbitrary building or structure or the surface of a floor substrate 1. 2 is formed, and after drying, the peelable plastic layer 2 is cut out into an arbitrary pattern, and a finishing material is sprayed on the surface, or brushed and ironed to form a finishing material layer 3, and in this state, the finishing material layer 3 After curing, the remaining peelable plastic layer 2 is peeled off to form a predetermined pattern of the finishing material layer 3.

A vinyl chloride-vinyl acetate copolymer resin is used as the peelable plastic.

[0008]

As described above, since the liquid peelable plastic is applied to the surface of the substrate 1 to form the peelable plastic layer 2, the peelable plastic layer 2 conforming to the unevenness of the surface of the substrate 1 is formed. To be done. Since the peelable plastic layer 2 is peeled off according to the pattern to form a mask, even a mask having a complicated pattern can be formed in close contact with the base material 1 and a complete pattern can be reproduced without the finishing material wrapping around the back side of the mask. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an explanatory view of a construction process of the present invention, which is a sectional view of a base material and a coated portion. As this construction process, (a)
The peelable plastic layer 2 is formed by spraying or brushing the peelable plastic layer 2 on the substrate 1 as shown, and the peelable plastic layer 2 is cut along a desired pattern as shown in (b). Expose the surface to be painted. Next, as shown in (C), spray a finishing material over the entire surface, or brush,
Alternatively, it is applied with a trowel to form the finishing material layer 3. After the finishing material layer 3 is dried, the peelable plastic layer 2 left in the step (b) is peeled off together with the finishing material layer 3 applied thereon, and cut off in (b). The finishing material layer 3 is formed only in the pattern portion.

The material used for the base material 1 may be any one as long as it has strength according to its purpose, such as concrete,
What is generally used as a surface finishing material for building materials such as cement mortar, wood and brick can be used, but it can also be used when the finishing material is applied again to the surface on which the finishing material layer 3 is formed.

The peelable plastic is a quick-drying liquid material, and 245 parts of an organic solvent in which 100 parts of vinyl chloride-vinyl acetate copolymer resin is used alone or as a diluent MEK, toluene, xylene or the like is used. A mixture was used. In consideration of cold resistance, ultraviolet deterioration, etc., a drug that suppresses them may be added within 10 parts.

The method of application is spray coating or brush coating. In the case of spraying, 0.2 mm is standard for one spray, so spraying 3 to 4 times gives a thickness of 0.6 to 0.8 mm. To get.

In the case of brush coating, it is diluted with the above-mentioned organic solvent between 250 and 280 parts per 100 parts of the copolymer before use. A single application should give a thickness of 0.5 to 1 mm. If the thickness is 0.4 mm or less, the peelable plastic layer 2 may be broken, and at least 0.
A thickness of 5 mm is required.

It is effective to use a tip of a cutter knife or the like to cut off the peelable plastic layer 2, and a blade is vertically pierced on the peelable plastic layer 2 until it reaches the substrate 1, and cut along the line of the pattern. To do. When you're done cutting, use the cutting edge to lift it off.

As the material used for the finishing material layer 3, cement mortar, sick and other materials generally used as a surface finishing material for buildings can be used, but the coating surface has a viscosity at the time of spraying and a concavo-convex pattern thereafter. As a material satisfying the moldability and the protective ability of the structure and the structure when it is cured, a liquid curable resin, a synthetic resin emulsion, an inorganic filler, a pigment or the like is preferably added.

As the liquid curable resin, epoxy resin,
Unsaturated polyester, urethane resin, MMA and the like are used, and as the synthetic resin emulsion, acrylic acid-based emulsion, vinyl acetate emulsion, ethylene-vinyl acetate emulsion, epoxy resin emulsion and the like are used.

Inorganic fillers and pigments added to this are calcium carbonate, silicic acid anhydride, talc, cement,
A filler such as white cement or porcelain powder with little deterioration, iron oxide, chromium oxide, titanium oxide, carbon black, an aqueous pigment, or the like is used. Also, as its extender, alkylphenol, phthalate ester, asphalt,
Tar or the like can also be added.

The finishing material layer 3 is applied to the surface of the substrate 1 by a known method such as spraying, brush coating or iron coating, and the thickness is empirically determined depending on the properties of the finishing material.

Experimental Example 1 M based on 100 parts of vinyl chloride-vinyl acetate copolymer resin
A mixture of 100 parts of EK, 100 parts of toluene and 45 parts of xylene was sprayed as a peelable plastic on the concrete surface with a pressure sprayer. Liquid surface pressure at this time is 1.5k
The one having a gf / cm ² and a nozzle diameter of 2 mm was used.

Spraying was carried out four times to obtain a film thickness of 0.8 mm. After spraying four times, one hour later, circles, triangles, and squares were drawn on the surface in arbitrary sizes and cut with a cutter knife.

As a finishing material, 3 parts of an aqueous pigment and 20 parts of an acrylic acid emulsion were mixed and stirred with 100 parts of white cement, and the cut portion was applied to a cut portion with a thickness of 1 mm. After leaving for about 1 hour, all the peelable plastics were removed. As a result, circles, triangles, and squares of arbitrary size remained sharp, and there was no bleeding or corner loss.

Experimental Example 2 MEK100 was added to 100 parts of the copolymer resin of Experimental Example 1.
Part, toluene 100 parts, and xylene 65 parts were mixed and applied once as a peelable plastic to the concrete surface with a brush. The film thickness was 0.5 mm, and after 1 hour from application, the same pattern as in Experimental Example 1 was drawn by the same method, cut out, and the same finishing material was applied with a iron thickness of 0.6 mm. After leaving for about 1 hour and removing all the peelable plastic, the same pattern as in Experimental Example 1 was obtained.

[0023]

EFFECTS OF THE INVENTION By applying a liquid peelable plastic to a base material, the adhesion to the base material is so strong that it cannot be compared with the pattern paper and masking tape.

Further, since the pattern is formed by cutting out, when changing the color tone, it is sufficient to cut out only the portion of the same color and not the other color tone portions, so that extra labor for curing can be omitted.

It can be applied not only to the inner and outer walls of houses and buildings, but also to structures such as retaining walls, fences and flower beds, and is also used as a base material constructed on site and a base material to be assembled from now. it can.
