The present invention relates to a crack pattern forming ink, a coating agent for forming a crack pattern, a crack pattern forming method using the same, and a panel on which a crack pattern is formed.

In general, when the building material is formed of glass, panels, etc., various patterns, patterns, etc. are formed on the surface of the glass panel in order to increase the aesthetic appearance.

Many techniques are already known for the method of print coating a pattern, pattern or the like on a surface. Korean Patent Publication No. 91-2529 describes a negative pattern on an object surface by applying a paste by screen printing, and then heats it at a temperature of about 400 ° C. or higher and then reacts with the surface of the uncoated object by screen printing. Disclosing a method of coating a glossy pattern on the surface of the object by immersing a heated object having a negative pattern in the oxide solution, forming a glossy pattern on the surface of the uncoated object, and then removing the negative pattern from the object have.

In addition, Japanese Patent Publication Nos. 52-41682 and 57-50547 disclose a method of printing (coating) a transfer film to print a pattern on the surface of various objects.

However, the above printing methods have a problem in that the printing (coating) process is complicated and the selection of materials is limited, and the printed coating is less durable and easily discolored or discolored. The pattern has to be made on the film, and the expensive printing cost is required, so there is a limit to the practical use.

In order to solve the problems of the prior art, it is inevitably required to develop a printing method of a natural pattern, which is simple in the printing process and is not limited by the material, and has a durability capable of highlighting a high quality image.

Example 3 Crack Pattern Formation Method Using Crack Pattern Forming Ink

The crack pattern forming method according to the present invention is coated with a panel using a novel coating liquid (No1, 2, 3) composed of the same composition as that of Example 1, that is, a coagulation solution and a diffusion solution, and then thermally dried. A method of forming a crack pattern by forming a crack pattern, and using a coating agent having the same composition as in Example 2, comprising the steps of: drawing with the ink on a panel; drying the drawn panel; Sputtering the surface of the panel with gold, silver, copper, chromium, aluminum, nickel or titanium, alloys thereof, or oxides thereof to deposit a metal film, and applying a coating agent to the panel on which the metal film is deposited, 1 to 30 Heat treatment at 60 to 150 ° C. for minutes.

Hereinafter, the crack pattern forming method according to the present invention will be described in detail.

First, a crack pattern forming ink composed of a flocculating solution and a diffusion solution as described above is prepared.

The crack pattern forming ink on the panel is drawn or coated with a desired picture or text.

As the panel used in the present invention, paper, glass, ceramics, metals, synthetic resins, and the like may be used, and those having a plate shape or curvature may be used. In particular, a transparent material such as glass or synthetic resin may be used as a material, and in this case, various patterns are designed using color inks or hydrofluoric acid inks to further maximize the beauty and decorative effects of printed printed materials. Can be.

In addition, the drawing or coating method can apply various drawing or coating methods, such as the screen printing method, the spray coating method, the roller coating method, the infiltration coat method, etc. which are used conventionally. Various such methods are applied to apply the appropriate thickness, preferably, the thickness of the coating liquid is 0.1 mm or more. This is because when the thickness of the coating liquid is less than 0.1 mm, the crack pattern pattern due to the difference in reactivity between aggregation and diffusion is not expressed.

 Thereafter, the drawn panel is dried. At the time of drying, it is dried at 10-60 degreeC under 60% of relative humidity. After drying, the solvent and the volatile components are volatilized in the surface layer of the coating liquid (cracks pattern forming ink) coated on the surface of the panel, and as a result, the inner layer of the coating liquid is delayed in comparison with the surface layer, and the aggregation solution is the surface layer. Since the diffusion solution tries to diffuse in the surface layer, shrinkage occurs in the surface layer, whereby a crack pattern pattern is formed on the surface of the material.

At this time, the relative humidity plays an important role in forming the crack pattern pattern. In other words, when the relative humidity exceeds 60%, the relative humidity is too high, the solvent volatility of the coating liquid coated on the surface layer of the panel is reduced, not only to form a crack pattern pattern, but also to moisture condensation on the surface of the panel A phenomenon occurs that causes a problem that prevents formation of a crack pattern pattern. Therefore, in the drying step, the relative humidity is maintained at 60% or less to form a crack pattern pattern.

On the other hand, it is the temperature condition that is important in forming the relative humidity. This is because the size of the crack pattern formed by the temperature conditions can be adjusted. That is, the lower the temperature at the time of drying, the smaller crack pattern is formed, and the higher the temperature at the time of drying, the larger crack pattern is formed. This is because the volatility of the solvent, that is, the chemical reactivity of the flocculation solution and the diffusion solution differs depending on the drying temperature. Due to such chemical reactivity, a crack pattern having a good three-dimensional effect is formed.

In more detail, as the crack pattern is cured, the surface layer of the usual coating solution is cured, and shrinkage occurs due to the difference in curing time with the lower portion of the surface layer, so that the crack pattern is formed, and immediately after the crack pattern occurs, the lower inner layer of the surface layer is again As it hardens, shrinkage occurs due to a difference in hardening time from the lower part of the inner layer, and a crack pattern is generated. This process is repeated to gradually increase the number of occurrences of the crack pattern, thereby decreasing the size of the crack pattern. will be. On the contrary, when the temperature is high, since the crack pattern forming process is performed for a short time, the number of occurrence of the crack pattern becomes small, and the size of the crack becomes large. Therefore, when the temperature is properly adjusted during drying, the size of the crack pattern pattern formed can be adjusted.

Although the temperature at the time of drying is not specifically limited, It is more preferable to dry at 10-60 degreeC. In other words, if the drying temperature is less than 10 ° C., the size of the crack pattern is too small, and the merchandise is less. If the drying temperature is more than 60 ° C., the size of the crack pattern is too large. not. Therefore, it is most preferable to dry in the temperature range of 10-60 degreeC, changing temperature suitably according to the characteristic of a panel, a product, etc.

More preferably, at the time of drying, it is subjected to a process of sufficiently low temperature drying at room temperature, not a heat drying method. When such low temperature drying is carried out, the solvent inside the coating liquid gradually moves to the outside to volatilize to prevent the formation of pinholes, and in particular, complete drying is possible.

Therefore, by adjusting the size of the crack pattern in consideration of the relative humidity and the drying temperature, and sufficient drying time, sufficient complete drying was achieved, and a better crack pattern could be obtained.

Meanwhile, a metal film is deposited by sputtering gold, silver, copper, chromium, aluminum, nickel or titanium, alloys thereof, or oxides thereof on the surface of the dried panel.

To deposit a metal film, and the like conventional vacuum vapor deposition method, but can be formed by applying a variety of ways, the present inventors on the high vacuum state of 10 ^-4 torr to deposit charged into the metal material as described above, while applying a current The vacuum sputtering method was adopted, and the thickness of the deposited metal film was set to 0.01 to 0.5 mu m.

A coating as described in Example 2 was applied to the panel on which the metal film was deposited and heat treated at 60 to 150 ° C. for 1 to 30 minutes.

The panel coated and heat treated is not easily peeled off by the coating effect from the metal film. For example, when the panel is glass and gold is deposited, since gold is a very weak metal, it is easily peeled off and peeled off from the deposited glass. As a result, the coated gold is flawed in the appearance and decorative properties, so in fact, care must be taken in storage and there is a problem that the storage property is poor. However, by adding a diluent to a coating agent, that is, a crack pattern forming ink according to the present invention, by applying a coating on the surface of the panel coated with the metal film, a coating effect of the metal film is generated.

That is, in the present invention, unlike the conventional coating, the coating is not applied to the panel before the deposition of the metal film to improve adhesion of the panel surface, but after the deposition of the metal film, the panel is coated to prevent the metal film from falling off the panel, It is for improving the coating property. The metal film formed as described above can obtain a diffuse reflection effect by the crack pattern generated by the difference in the reactivity between the aggregation solution and the diffusion solution, resulting in a more beautiful and elegant look.

Example 4 Panel with Crack Pattern

It was applied to the glass panel through the crack pattern forming ink prepared in Examples 1 to 3 and the crack pattern forming method using the same.

The following physical properties were examined and compared to the glass panel on which the crack pattern was formed, and are shown in Table 3 below.

Light transmittance (%) Adhesion Test (Residual Water) Peel Strength (kg / cm) Exfoliation NO.1 91 98/100 0.7 x NO.2 89 100/100 0.68 x no.3 90 95/100 0.72 x Comparative example 76 0/100 0.14 0

As described above, it can be seen that NO.1, NO.2 and NO.3 according to the present invention show remarkable peel strength and adhesion test results compared to the comparative examples. Thereby, if the crack pattern forming ink and coating agent according to the present invention is prepared, and a crack pattern is formed on a panel of glass, metal, paper, ceramic, synthetic resin, etc. using the same, even if coating with a weak adhesive metal, Since the coated metal is not easily peeled off or peeled off, crack patterns can be well preserved and a panel in which various crack patterns are formed can be obtained.
