Description

The present invention relates to a method for easily forming a joint pattern on an outdoor wall of a house, a fence or the like. More specifically, to provide a method capable of easily forming a colored joint pattern in which a joint portion separating a wall surface or a joint portion between tiles can be easily colored, and as a result, there is no change with time such as peeling. is there.

(Prior art) In order to attach tile pieces while forming joints on the exterior walls of houses or on the surface of outer walls, it is made of a mold material that has a continuous pattern of joints existing between tiles, such as colored paper or colored plastic. Press the mold material with tile joint pattern with openings according to the position and size of the tile against the application surface of cement mortar, plaster, synthetic resin emulsion, etc., and put ready-made tiles of the appropriate size in the openings. A method is known in which a tile is attached with colored joints by inserting and adhering it together with a mold and completing solidification of the coating material.

Further, instead of forming a tile pattern, a wide wall surface is simply divided into a desired size, and a joint pattern is formed to prevent cracking due to shrinkage during wall surface formation. Occasionally, a linear mold made of colored paper or colored plastic was embedded.

Further, the above-mentioned mold material is made into two layers having peeling property, one of the opposite surfaces of the two layers is colored as desired, and press-fitted to a desired depth on the application surface such as cement mortar to open the mold material. A method has also been adopted in which the raised coating material on or around the area is smoothed and solidified, and then the outer layer of the template is peeled off to form a clean joint pattern with or without a tile pattern. .

However, in addition to using ready-made tiles, a major problem with these methods is that the molding material for joints must remain on the surface of a wall or the like. That is, when a method of leaving the mold material on the surface of a wall or the like is adopted, the adhesion between the mold material and the coating material due to wind and rain due to the difference in the coefficient of thermal expansion or contraction between the mold material and the coating material of the wall after a long time has passed. It has been a problem in many cases that the mold material comes off due to a decrease in force.

(Problems to be Solved by the Invention) In view of these problems, the present inventor has identified a material that is easy to work and that does not leave a joint mold material on the surface of a wall or the like, and thus may peel off. The purpose was to find a method capable of forming a colored joint that does not change with time without leaving.

(Means for Solving the Problems) As a result of intensive research to solve the above problems, the present inventor migrates to the coating surface of the coating material and the inside of the coating surface when the coating material is kept in contact with water. The inventors have found that the problem can be solved by using a mold material for joints having a peeling property, to which a coloring material is applied.

That is, the gist of the present invention is a joint pattern forming mold material before solidification on the coating surface of a solidifying water-dispersible coating material, one surface of which is subjected to a water repellent treatment, and further the solidifying water-dispersible coating material before solidification is formed. After contacting the coating surface of the mold material to which the joint colorant having migration property is applied, the mold material is press-fitted into the paint, and if necessary, the paint around the press-fitted mold material is leveled. After that, after leaving at least a part of the joint colorant for a desired time to move the coating surface and the inside of the coating surface,
It is a method for forming a joint pattern by peeling and removing the mold material.

The details of the present invention will be described below.

The solidifying water-dispersed coating material referred to in the present invention is a hardened cement (for example, anhydrous gypsum plaster, dolomite plaster, etc.),
Inorganic paints such as cement mortar using hydraulic cement (normal Portland cement, alumina cement, mixed cement, etc.) as well as synthetic resin emulsion (ethylene vinyl acetate, ethylene acrylic acid, etc.) organic paints A medium that is used as a medium to form a coating film by reacting with mixed water after coating, reacting with carbon dioxide in the air, or drying, and is usually applied to the outside wall of the house or the wall surface. . In addition to being used alone, these paints are often used by mixing an aggregate, a coloring material, a foaming material and the like.

As the coating material used in the present invention, it is difficult to use a material that solidifies in a short time after coating on the objective, and it is preferable that it does not solidify for at least 1 to several hours, but it is the object of the present invention to solidify in about 10 to 20 hours. Stable coloring can be achieved more preferably for a certain coloring. The reason for this cannot be clearly explained, but it is also considered that it may take a considerable time for the coloring material described later to move to the inside of the coating surface.

The shape of the joint pattern forming mold material used in the present invention is not particularly limited, in addition to a linear mold member having a corresponding width for dividing a wide wall surface to form a joint having a desired width,
In general, a mold material for tiles, that is, a mold material that is configured by cutting out only the tile portion in consideration of the tile arrangement and leaving only the remaining portion. In the case of a straight shape material, the desired joint length,
There is the convenience that they can be connected appropriately depending on the shape. The tile mold material is usually discontinuous and arranged in a checkered pattern or a zigzag pattern, but it may be arranged in an irregular shape for the sake of taste. In the case of a tile mold material, mold materials of a predetermined size are repeatedly arranged and used in a form of being connected to each other, and a tile or joint pattern becomes a repeating pattern.

The material of the mold material is not particularly limited, but it is usually used in a long length or a wide area, so that it is necessary to have some rigidity in consideration of workability. For example, paper with a thickness of 2 to 3 mm or more, or plywood with a thickness of 1 mm or more. Is preferred.

On the other hand, since the coating material is water-based, the original purpose cannot be achieved if this mold material absorbs water and its strength is extremely reduced, or if it is severely swollen and deformed. Therefore, those that have been subjected to water resistance treatment are preferable. With respect to this point, there is generally no problem in the case of synthetic resin, but polypropylene resin, polystyrene resin, nylon and the like are preferable in consideration of the rigidity.

A method of making a mold using these materials does not require a special method, and a material having a predetermined thickness and size may be prepared to make a straight mold or a mold having a tile opening.

The joint colorant is applied to one surface of the mold material, but as described below, the mold material must be easily peeled off from the solidified surface of the paint after the colorant is transferred to the paint application surface and the inside of the application surface,
For this purpose, it is necessary that the surface of the mold material has water repellency so as not to have an affinity for the solidifying water-dispersed paint. The above plastic has water repellency, but paper or wood generally requires water repellency treatment. For example, a silicone resin treatment or a method of forming a thin layer of plastic may be used. However, the degree of water repellency is appropriately adjusted according to the type of the coloring material because of the necessity of applying the coloring material described later.

The joint colorant having migration property in the solidifying water-dispersed coating material of the present invention is a coating material on a wall surface etc. when the surface is applied to the water repellent surface and solidified and then the surface is brought into contact with the unsolidified coating material surface. It refers to a coloring material that colors the surface and the interior of the paint, and specifically refers to an aqueous dispersion of a pigment or a dye or an aqueous solution itself, or one to which a dispersant or a spreading agent is added. Here, the water dispersant or spreader means that the pigment or the dye is uniformly present in the water and does not easily cause aggregation or precipitation, and that the pigment or the dye can be attached to the mold material during drying. , Water-soluble or water-dispersible alkyd resin, acrylic acid resin, epoxy acrylate, synthetic drying oil, synthetic latex, water glass, and casein,
Soluble starch, dextrin, methyl cellulose, polyvinyl alcohol resin, water-soluble glue such as glue and the like are used. Ink soup is also suitable. Typical pigments include titanium oxide, carbon black (furnace black, channel black, etc.) and red iron oxide.

The above-mentioned water dispersion or aqueous solution has a high viscosity and is applied to the water-repellent mold material in an appropriate thickness to be dried. However, if this application surface is brought into contact with the application surface of the unsolidified water-dispersion coating material, the above-mentioned drying occurs. The colorant thus obtained gradually wets and elutes, and starts to move to the unsolidified paint. In this case, since the coloring material is once dried and solidified, it does not spread instantaneously and widely on the coating surface and the inside of the coating surface of the unsolidified coating material. Utilization of this phenomenon is the most important point of the present invention and brings remarkable technical effects. It is presumed that the dispersant and the spreading agent are those that appropriately control the migration of the coloring material of the present invention. It seems that all of these do not migrate to the non-solidified paint, but it has been observed that some of them migrate to the aqueous solution or water dispersion state for a long time.
Further, it is considered that such a transition process suppresses the abnormal dispersion of the colorant on the coated surface and the inside of the coated surface.

Since the migration of the colorant is suppressed as the coating material solidifies, the solidification rate is appropriately selected depending on the type of the colorant.

After the transfer of the colorant is completed, confirm that the paint has solidified and gently peel off the joint template. In this case, since the surface of the mold material has water repellency as described above, the solidified coating material does not adhere firmly to the mold material and the peeled surface is not roughened.

The formation of the joint pattern in the present invention is performed by press-fitting the mold material to a desired depth after applying the water-dispersed paint, and if necessary, the paint around the mold material is leveled with a trowel, but in the case of a tile pattern. This flattened portion corresponds to the tile. When coloring the tile pattern surface, a desired coloring material may be added to the coating material, or the coloring material may be sprayed after the coating material is solidified. Next, an embodiment of the present invention will be described with reference to the drawings.
