Abstract

PURPOSE:To obtain a non-standardized and natural-looking striped pattern which is visualized not by printing. CONSTITUTION:A patterning agent 3 of dye or pigment is applied over almost the entire surface of a background coat 2 after forming the background coat 2 on the surface of a base 1. Next, a liquid 4 such as a solvent with a low surface tension is applied in lines by allowing the liquid 4 to run meanderingly on the patterning agent 3. After that, a shaded pattern is formed in a stripe by moving the patterning agent 3 using the liquid 4. The liquid 4 moves the patterning agent 3 as a carrier to visualize a striped pattern and the striped pattern becomes curved due to the meandering of the liquid.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a patterning method for expressing the appearance of natural stone, artificial stone, etc.

0002

[Prior Art] Natural stones such as marble have traditionally been used as building materials, but natural stones are heavy, break easily, have poor workability, are susceptible to chemicals such as acids, and are susceptible to frost damage due to water absorption. Due to these drawbacks, recently, artificial stones such as artificial marble formed by patterning a stone pattern such as a marble pattern on the surface of a base material have been used as a substitute for natural stone.

[0003]The most widely used method for forming stone patterns such as marble patterns is to print the pattern on the surface of the base material.

0004

[Problem to be solved by the invention] However, when patterning is done using the printing method as described above, a printing plate is made and the printing is performed using this plate. ■The patterns can only be printed using a uniform plate, and it is not possible to express a variety of different patterns like natural marble, so if you want to express a variety of patterns, you will need many plates. ■You can only print on a base material that is compatible with the size of the plate, so you cannot use a large base material.■You cannot print if the base material has irregularities such as embossing, so it cannot be used. There are problems such as not being possible.

The present invention has been made in view of the above points, and provides a patterning method that can express a non-uniform pattern without using a printing method, and can also form a natural pattern. The purpose is to provide the following.

[0006]

[Means for Solving the Problems] The patterning method according to the present invention involves forming a base coating film 2 on the surface of a base material 1, and then applying a patterning agent 3 of dye or pigment almost entirely on the base coating film 2. A liquid 4 such as a solvent with low surface tension is applied onto the patterning agent 3 in a meandering manner in a plurality of lines, and the patterning agent 3 is moved by the liquid 4. This is characterized by forming a striped pattern of shading, and further forming a clear top coat film 5 on top of this.

[0007]

[Operation] By applying a patterning agent 3 of dye or pigment on the base coating film 2 and applying a plurality of liquids 4 such as a solvent with low surface tension on this patterning agent 3 in a plurality of lines, The liquid 4 acts as a carrier to move the patterning agent 3 and partially collect the patterning agent 3 in a linear manner to form areas with more and less amount of the patterning agent 3, thereby changing the shading of the color pattern etc. It is possible to express a linear pattern. Moreover, this liquid 4
Since the liquid 4 is applied in a meandering line, the linear pattern formed by the liquid 4 acting as a carrier has a meandering curved shape, making it possible to express a pattern that is not uniform.

EXAMPLES The present invention will be explained in detail by way of examples. The base material 1 includes metal plates such as aluminum plates, stainless steel plates, and iron plates; inorganic plates such as asbestos cement plates, calcium silicate plates, and gypsum slag plates; wood plates such as plywood and wood plates;
A resin board such as an FRP board can be used. There is no problem even if the surface of this base material 1 is uneven (embossed), but since marble is usually used with a smooth finish, when used as artificial marble, the surface should be formed smooth. It is common to use a base material 1 that has undergone a process. First, in a base coloring step, a base coat is applied to the surface of the base material 1, and a base coating film 2 is applied thereto. The purpose of the base coating film 2 is to hide or color the base color of the base material 1, and it is preferable to use an enamel-based paint that has concealing properties and coloring effects. Coating can be carried out by any method using a roll coater, flow coater, spray, etc. alone or in combination.

In this way, the base coating film 2 is formed on the surface of the base material 1.
After forming the base coat 2, a patterning agent 3, that is, a dye or a pigment, is applied to form a coating film of the patterning agent 3. The patterned coating film 3 is created by dissolving the patterning agent in a solvent and applying it on the base coating film 2, thereby creating a uniform film thickness as shown in Fig. 2.
It can be formed as shown in (a). As the solvent at this time, organic solvents such as ester-based and ketone-based solvents can be used, and the patterning agent 3 is dissolved at a ratio of, for example, about 3 parts by weight to 100 parts by weight of the solvent.
By applying this using a roll coater, spray, etc., a coating film of the patterning agent 3 can be formed with a dry film thickness of about 1 μm.

After applying and drying the coating film of the patterning agent 3 as described above, the base material 1 is arranged so that the coating film of the patterning agent 3 is on the upper surface, and a liquid with extremely low surface tension is formed. 4 on top of patterning agent 3. As the liquid 4 having extremely low surface tension, ester-based, ketone-based, or alcohol-based organic solvents with low boiling points can be used singly or in combination. Here, the liquid 4 is as shown in FIG. 1(a).
The liquid 4 is continuously applied in a plurality of lines at predetermined intervals as shown in FIG. The liquid 4 is applied in a plurality of parallel lines by moving the material 1 in the direction of the arrow A or by moving the head 8 relative to the base material 1 in the direction of the arrow B. At this time, the liquid 4 can be applied in a meandering curve by moving the head 8 back and forth in directions C and D perpendicular to the directions of travel A and B. be. Then, when the liquid 4 is applied in a plurality of meandering lines onto the patterning agent 3 in this way, when the liquid 4 applied in the lines spreads, the liquid 4 becomes a carrier as shown in FIG. 2(b). As a result, the patterning agent 3 is moved, and the patterning agent 3 is carried between adjacent liquids 4 and collected in a line, especially in the area where the adjacent solvents 4 intersect. In this case, the thickness of the patterning agent 3 becomes thicker and darker, and the thicker and thinner portions of the patterning agent 3 are formed alternately in a linear manner, forming stripes of light and shade of color. . Since the liquid 4 evaporates in a short time after being applied, the patterning agent 3 is carried along with the liquid 4 without being dissolved in the liquid 4. Therefore, as the liquid 4 having extremely low surface tension, it is preferable that the dissolving power of the patterning agent is not very high. In addition, when applying the liquid 4 in a linear manner, the adjacent liquid 4
, 4 is larger than the width that allows the liquid 4 to spread and merge, the patterning agent 3 cannot be collected linearly using the liquid 4 as a carrier. It is preferable to set the application position of the liquid 4 so that the width is equal to or smaller than the width that allows the liquid to join.

When the liquid 4 applied as described above is evaporated (volatilized), the patterning agent 3 remains in a linearly unevenly distributed state, and the patterning agent 3 remains in a linearly unevenly distributed state. In areas where there is less adhesive 3, the color of the base coating film 2 mainly appears, and in areas where there is more patterning agent 3, the color of patterning agent 3 mainly appears.By contrasting the colors, subtleties that cannot be obtained with printing methods can be obtained. It is possible to express stone-like striped patterns such as deep marble patterns. Moreover, since the liquid 4 is applied in a meandering curved shape as described above, the patterning agent 3 is also unevenly distributed in a meandering curved shape, resulting in a continuous curved striped pattern with a marble-like variation. can be expressed. Furthermore, the shape of this curve can be arbitrarily and randomly formed by changing the left and right feed speed and feed width in the C and D directions of the head 8 in FIG. 1(a). It is possible to express a non-uniform striped pattern.

As described above, the liquid 4 is applied in a linear manner to form a pattern using the patterning agent 3, and after this solvent 4 is blown off, a top coat is applied thereon as shown in FIG. 2(c). A film 5 is formed. The top coat film 5 is formed to impart surface hardness, light resistance, chemical resistance, moisture resistance, etc., and to obtain depth of the pattern, surface gloss, surface smoothness, etc. It is preferable to use a two-component type such as a polyester type, acrylic type, or urethane type or an ultraviolet curing type clear paint. Further, it is preferable to use a color clear paint as the clear paint to form the color clear top coat film 5. Color clear paint is made by adding coloring pigments to regular clear paint, and it has both a coloring effect and transparency, and can emphasize the depth of the pattern.
Therefore, by using color clear as the top coat film 5, it is possible to express the depth of the pattern and the change in color even more than with transparent clear. In order to effectively create more depth, it is preferable to increase the thickness of the top coat film 5 by applying multiple coats. The coating for forming the top coat film 5 can be carried out by any method using a roll coater, a flow coater, a spray, etc. alone or in combination. Furthermore, the sense of depth can be further increased by polishing the surface of the top coat film 5 in order to eliminate foreign matter, air bubbles, and minute irregularities on the surface.

Effects of the Invention As described above, the present invention involves forming a base coat on the surface of a base material, and then applying a dye or pigment patterning agent over almost the entire surface of the base coat to create a pattern. A liquid such as a solvent with low surface tension is applied in multiple lines onto the paint film, and the liquid moves the patterning agent to form a striped pattern of shading. The liquid applied in a linear manner acts as a carrier and moves the patterning agent, forming areas with more and less patterning agent in alternating lines. , it is possible to express a striped pattern such as a stone tone by contrasting the shading of linear color patterns, and it is possible to form a natural-looking pattern without using a printing method. Moreover, since the liquid is applied in a linear pattern while meandering, the linear pattern formed by the liquid acting as a carrier has a meandering curved pattern, creating a natural striped pattern that is not uniform. It is something that can be done.
