Description

  The present invention relates to a drawing tile on which an image is printed and a manufacturing method thereof, and more particularly to a drawing tile on which an image is printed using an inkjet printer and a manufacturing method thereof.

In this specification, “tile” includes pottery, porcelain, plastic, and metal.

  In Patent Document 1, the upper surface portion of the tile material is subjected to a ground treatment, and the surface portion of the ground treatment is directly drawn with an ink jet drawing machine, and the pattern processing is performed. A method of manufacturing a tile that forms a coating layer with excellent properties is disclosed.

  According to this tile manufacturing method, when, for example, a vinyl acetate solution is applied to the surface of the tile material as a base treatment, the vinyl acetate is firmly attached to the surface of the tile material, and the surface portion has a hydrophilic state. Become. It is said that when a desired pattern is made on the hydrophilic surface portion by an ink jet drawing machine, the ejected ink penetrates into vinyl acetate.

JP-A-5-317803

  However, the tile disclosed in Patent Document 1 has a problem that a drawn image is blurred by moisture such as rain because the surface portion has hydrophilicity.

  In addition, since the tile is porous in the first place, if moisture such as rain enters from the bottom of the tile, the moisture adheres to the vinyl acetate. After that, when the moisture is vaporized by irradiation with sunlight, the volume increases, so there is a problem that the drawing surface swells and the drawing surface is cracked or cracked. Arise.

  Therefore, an object of the present invention is to provide a drawing tile that can withstand moisture such as rain and a drawing method on the tile.

  In order to solve the above problems, the tile of the present invention is coated with ink sandwiched between first and second layers having water repellency.

  Either of the first and second layers may include a material contained in the ink. The first layer under the ink may have a rough contact surface with the ink. This is because the fixing force between the first layer or the second layer and the ink is improved.

  In addition, it is preferable that the second layer on the ink is provided with an anti-slip aggregate because the drawing tile can be used as a flooring.

Furthermore, the method for producing a drawing tile of the present invention includes:
Forming a first layer having water repellency on the tile;
Discharging ink onto the first layer;
A second layer having water repellency is formed on the ink.

It is a figure which shows the typical manufacturing process figure of a drawing tile.

100 Tile 102 Dust 104 Underlayer 106 Ink 108 Coating Layer 110 Aggregate 112 Protective Layer

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram showing a schematic manufacturing process diagram of a drawing tile.

(Step S1)
First, a drawing target tile 100 is prepared. The tile 100 is preferably plain and has a flat surface. In addition, the tile 100 here may be a thing which has already been constructed as a wall material etc., or may be a thing before construction.

(Step S2)
Since dust 102 or the like may be attached to the surface of the tile 100, the surface of the tile 100 is diluted with hydrochloric acid diluted with alcohol, thinner or benzene about 50 to 100 times or about 50 to 100 times. Wash using a solvent such as diluted diluted sulfuric acid. The cleaning may be performed to such an extent that it can be determined that the dust 102 is not attached visually.

(Step S3)
Subsequently, a water-repellent base layer 104 made of a resin such as acrylic silicon, epoxy, or urethane is applied to the surface of the tile 100. The thickness of the foundation layer 104 may be about several μm to several tens of μm. Note that the material of the underlayer 104 is preferably contained in the ink jet ink so that the fixing power with the ink is strong. In this embodiment, acrylic silicon is used.

(Step S4)
Next, the surface of the underlayer 104 is roughened by sandpaper having a roughness of about 80 to 400. Specifically, for example, when No. 120 sandpaper is used, the surface of the tile 100 may be rubbed several times with a pressure of about 2 kg. When the size of the tile 100 is about 30 cm × 40 cm, the entire surface is rubbed in about 30 seconds to 40 seconds.

(Step S5)
Thereafter, a personal computer, a digital camera, or the like in which an image to be drawn on the tile 100 is captured is connected to the inkjet printer, and the tile 100 is set in the printer, and image data is output from the digital camera or the like to the inkjet printer. . As a result, drawing is performed on the base layer 104 of the tile 100 by the ink 106 ejected from the ink jet printer.

(Step S6)
Then, a coating layer 108 such as a thermosetting type, an ultraviolet curable type, or a photocurable type is selectively applied to the surface of the ink 106. As long as the coating layer 108 has excellent transparency so that the ink 106 can be visually observed, the material and the like are not particularly limited. Here, a coating layer 108 containing tilbin is used. In addition, for the coating layer 108, for example, urethane acrylate resin, epoxy acrylate resin, epoxy compound, oligoester acrylate resin, photosensitive polyimide, aminoalkyloxide, phenol resin, urea resin, melamine resin, etc. Can be used.

  In this embodiment, 30% to 35% of a modified polyurethane acrylate resin sold by Aika Industries, 30% to 35% of butyl acetate, 35% to 40% of methyl ethyl ketone (MEK), and 1% of other additives What was mixed at a ratio of about ˜5% was used as the coating layer 108.

  Here, when the tile 100 is used as a floor tile, the aggregate 110 or the like may be dispersed on the coating layer 108 so as not to slip even when rain or the like is attached. In this case, the aggregate 110 may have a particle size of about 150 μm to 250 μm and a ratio of about 65% to 85%, and a particle size of about 75 μm to 150 μm about 15% to 25%. In this embodiment, ceramic or resin beads having excellent transparency are used as the aggregate 110.

(Step S7)
Next, when the coating layer 108 is applied, the coating layer 108 is irradiated with heat, ultraviolet rays, or light under the required conditions.

(Step S8)
Finally, the protective layer 112 is formed on the coating layer 108. For example, the protective layer 112 is a mixture of a modified polyurethane acrylate resin in a proportion of 45% to 55%, an acrylic monomer in a proportion of 40% to 45%, and other additives in a proportion of about 1% to 5%. The material of the protective layer 112 is cured by ultraviolet irradiation or the like, whereby the protective layer 112 is formed. The protective layer 112 is not particularly limited as long as it has excellent wear resistance and durability, that is, strength, and transparency.

As an example, in order to further improve impact resistance and wear resistance, the protective layer 112 is made of fiber reinforced plastic (FRP) fiber or glass fiber (Nittobo Glass Fiber: Filament Mat MF30W). Etc.) can be mixed. Specifically, first, for example when used in tile 100 in the size of 300 mm ² is FRP fibers and the like, such as by cutting it to 270mm ² ~295mm ^2, keep the required size.

  Then, a material for the protective layer 112 made of a modified polyurethane acrylate resin or the like is applied on the coating layer 108, and then FRP fibers or the like are aligned and disposed on the material for the protective layer 112. At this time, air is vented so that no air bubbles remain between the material of the protective layer 112 and the FRP fibers, and then the material of the protective layer 112 is applied again on the FRP fibers and the like, and bones as necessary. After the material 110 is spread out, the material of the protective layer 112 is cured by ultraviolet irradiation or the like to form the protective layer 112.

  In addition, the durability of the drawing tile was simulated. In the case of conventional tiles, ink dropped in about 3 years, making it difficult to confirm the drawing. On the other hand, in the case of the drawing tile of the present embodiment, no ink drop was observed until about 10 years.
