Description

  The present invention relates to a method for forming a design coating film on a tension tile used for repairing a tile outer wall of a building such as an office building or an apartment, and a method for producing the tension tile. In particular, in order to repair the outer tile wall of a building that needs to be replaced due to missing tiles due to deterioration over time, even if the existing tile remaining on the outer wall of the tile is replaced, The present invention relates to a method of forming a coating film that most closely resembles an existing tile on a base material that becomes a tension tile so that the external appearance of the tile outer wall does not feel strange.

  Conventionally, tiles made of porcelain have been widely used as exterior materials on the outer walls of buildings such as office buildings and condominiums from the viewpoint of weather resistance, maintenance, design, cost, and the like. However, porcelain tiles are baked, so in order to make tiles with the same appearance and pattern, they need to be manufactured in large quantities at one time. Tiles are often manufactured in units. In addition to porcelain, rarely, ceramic tiles are used on the exterior walls of buildings.

  Tiles used as exterior materials after building office buildings and condominiums are subject to deterioration due to aging, discoloration, cracking, chipping, and peeling, requiring repairs each time. In this case, there is a method of manufacturing a large amount during construction and not using it as an exterior material, but using the original spare tile that was stored as a spare as a replacement tile, but it is used as an exterior material. Since existing tiles have deteriorated due to aging, etc., their colors and textures are different. When repairing a spare tile at the beginning of construction as a replacement tile, it looks very bad like a mottled pattern. Further, even if a new tile having the same color as an existing tile that needs repair is to be manufactured, a tile that is a porcelain ceramic product cannot always be manufactured in a manner that approximates an intended fixed color. In addition, as described above, tiles are usually manufactured in large quantities, and it is difficult to manufacture replacement tiles in a small lot for repair.

As a prior art, as described in Patent Document 1, in order to maintain the design, appearance and luxury as it is, and to make the tile wall surface excellent in weather resistance, waterproofness and durability, A tile wall refurbishment method has already been published, in which a plurality of clear coating materials are painted.
JP-A-6-33565

  As described above, ceramic-based exterior materials such as tiles require a firing process at a high temperature during production, and thus produce a tension tile with an intended color similar to an existing tile that requires tension repair. There is a problem that it is difficult. Therefore, when repairing the tiles used as the outer wall of a building such as an office building or an apartment, it will naturally harmonize with other existing tiles that are not subject to the replacement used on the outer wall of the building. It is difficult to secure a color-changeable tile, and it is very difficult to repair the tile to make it look natural after operation.

  In view of the above problems, an object of the present invention is to manufacture a replacement tile that is close to an existing tile of a building that needs replacement repair and that is in harmony with the pattern and color of other existing tiles. It is.

  Therefore, in order to solve the above-described problems, a method for forming a coating film on a design tile according to the present invention uses an air spray gun or a low-pressure hot air spray gun and applies the spray gun with an acrylic silicon resin paint or a fluororesin paint. In this method, the coating amount that is most similar to an existing tile used in an existing building is formed on a base material that becomes a tension tile by adjusting the amount applied and the dilution rate.

  Then, a roughening operation is performed on the surface of the base material on which the coating film is formed by a polishing machine as a pre-process. Next, (1) as a first step, after the roughening of the previous step, a primer which is an adhesive coating for fixing the resin coating to the substrate is applied. Further, (2) as the second step, the spray gun nozzle diameter is 1.0 to 1.3 mm on the coating film of the first step, and the dilution ratio of the resin paint containing the base color is 10 to 20%. Then, the base color is sprayed and painted with the spray gun. And (3) As the third step, on the coating film of the second step, the nozzle diameter of the spray gun is 1.3 to 1.8 mm, the dilution rate of the resin paint including color is 5 to 40%, By spraying with the spray gun, a pattern color and pattern of the existing tile are formed on the color of the base. (4) As the fourth step, on the coating film of the third step, the nozzle diameter of the spray gun is 1.0 to 1.8 mm, and the dilution rate of the resin paint containing color is 5 to 40%, By spraying and spraying with the spray gun, the fine grain pattern existing on the surface of the existing tile is reproduced, and the toner is adjusted in an appropriate amount with respect to the toner adjustment resin, and the finish close to the existing tile is obtained. Make adjustments. (5) As the fifth step, on the coating film of the fourth step, the nozzle diameter of the spray gun is 1.0 to 1.8 mm, and the dilution rate of the resin paint not containing color is 5 to 40%. Spray coating with the spray gun to form a top coat film that does not contain color, protect the color tone and adjust the gloss, and apply a paint film that most closely resembles the existing tile to the surface of the substrate. It is the coating-film formation method of the design tile to form.

  Various sanders are suitable for the polishing machine when performing the roughing operation on the surface of the base material by a polishing machine as a pre-process. For example, a disk sander can be used. Then, it is considered that the disc sander is equipped with a grindstone such as an offset grindstone or a diamond cutter for roughening. As the primer in the first step, a primer for tile is particularly suitable. For example, it is conceivable to use a strong adhesion primer such as an epoxy resin primer for tile. In addition, it is also conceivable that the tile primer contains a silane cup agent. Further, as the resin paint, an acrylic silicon resin paint or a fluororesin paint is conceivable. From the viewpoint of painting of tiles used for exteriors of buildings, a fluororesin that is excellent in terms of weather performance such as gloss retention Use of paint is conceivable. In addition, as the base material to be replaced tiles, there is a method of utilizing porcelain tiles and earthenware tiles, and the porcelain tiles and earthenware tiles may be colored or not. . Generally, porcelain tiles are widely used on the outer wall of a building. Therefore, if the existing tile to be replaced is a porcelain tile, the substrate may be a porcelain tile. . The surface of the base material is a surface that becomes the surface of the outer wall of the building and the appearance of the building.

  When the present invention is used, the primer is coated on the surface of the base material after the roughening work performed in the previous process, and then the second process, the third process, and the fourth process using the resin paint including color. Since the fifth step is performed as a top coat with a resin paint that does not contain colors, and the coating is well fixed, it is excellent in terms of weather resistance such as gloss retention, etc. A coating film forming method can be realized.

  Specifically, the coating in the second step, the third step, and the fourth step with the resin paint including color is performed from a relatively rough coating in which the nozzle diameter of the spray gun is in the range of 1.0 to 1.3 mm. Step by step to paint with a fine color in the range of 1.8mm, and the dilution rate of the resin paint is also a fine color in the range of 5-40% from the basic color in the range of 10-20% Since it is performed step by step, it is possible to realize painting of a tile that is closer to the existing tile. In addition, since the coating in the second, third, and fourth steps is performed on the primer coated in the first step, the fixing of the coating is improved and the coating is not easily peeled off. Furthermore, as a fifth step, a coating film of the top coat of the resin paint not containing color is formed on the coating of the second step, the third step, and the fourth step. A tile that is superior in terms of performance can be manufactured. In addition, since the primer coating in the first step is performed after performing the roughening operation on the base material surface in the previous process, the primer fixing is significantly improved compared to the primer coating without roughening the surface, As a result, the fixing of the coating after the second step is also improved, and it is possible to produce a tension tile having excellent weather resistance as a whole.

  In the second, third, and fourth coating steps, the base color is fixed to the base material in the second step, and the pattern color of the existing tile is added to the base color in the third step. Then, a pattern is formed, and a small grain pattern on the tile surface is reproduced in the fourth step. By this continuous process, it is possible to realize painting having an appearance similar to a tile used for the exterior of a building. Note that the toner adjustment resin is obtained by appropriately blending toner into the resin paint. Moreover, a 4th process can also be abbreviate | omitted among the coating of a 2nd process, a 3rd process, and a 4th process depending on the said existing tile. Furthermore, in the third step, depending on the type of the existing tile pattern, it is also effective to fix the resin paint including color on the base material using a brush or a sponge instead of the spray gun. .

  Therefore, unlike general tiles that are fired and manufactured in large quantities, tiles that remain as building exteriors and that have the same color as existing aged tiles can be manufactured individually in small lots. Has a remarkable effect.

  Further, for the purpose of forming a tile pattern, in the second and fourth steps, the nozzle diameter of the spray gun is 1.3 to 1.8 mm, and the dilution ratio of the resin paint including color is 5 to 40%. It is also conceivable that the toner is further finely adjusted to further approximate the existing tile including the texture.

  In this case, the colors used as the base of the second process and the tile exterior pattern, for example, tile spray pattern such as tile spray, lysine, lysine scraping, stucco, etc., in the fourth process finishing adjustment stage Form. Thereby, it is possible to approximate the existing tile more.

  Further, in the above-described design tile coating method, if the base material is a polyvinyl chloride sheet or an aluminum sheet, a sheet to be attached to the tile is manufactured with improved weather resistance while harmonizing the appearance with the surroundings. Can do.
