Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a decorative plate-shaped body and a method for producing the same, in detail, it is a method of molding a mottled pattern on a transparent plate-shaped body such as glass or plastic used for partitions, wall materials, etc. 9. IIS describes a decorative plate-like body and a method for manufacturing the same.

Conventionally, the method of decorating the surface of a transparent plate is screen printing or transfer printing4! There are other methods of forming the desired pattern, and in the example proposed by Okibe, colored opaque #41k paint is applied in spots on the glass surface, and the surface is coated with hammertone finisher or rough yarn paint. There is a method of coating the paint, curing it, and then applying an opaque paint called 1!1g (D J!) uniformly over the paint. In many cases, the decorative effect is damaged due to bleeding of different colors in the tomb boundary area, etc., and in the method of Hakukan, when applying the first coat on top of the base coat, the base coat and top coat are mixed. This poses a problem because it tends to react with the paint 0@ agent and cause so-called paint 7 creases, floating, and pinhole formations.

The present invention has been made as a result of intensive research aimed at solving the above-mentioned problems and obtaining a decorative plate-like body that can be manufactured easily.

That is, the first transparent resin m1 is placed on one surface of the transparent plate-like body.
A coating film of #4 (hereinafter referred to as the first solution) is formed, and then immediately on the # coating film, a coating film containing a resin different from the first solution, a compatible solvent, and an inorganic pigment, and a surfactant 11III.
A few droplets of the second resin paint (hereinafter referred to as the second liquid) are added, and the first liquid and the second liquid are not mixed, but the two liquids are adjacent to each other. A decorative plate-like body in which droplets form a mottled pattern without interconnecting, and a method for producing the same, further comprising: coating the first liquid and the second liquid on one surface of the transparent plate-like body. After that, a protective film of a third resin paint (hereinafter referred to as "third liquid") K is formed on these to form a decorative plate-like body.

According to the structure of the present invention, it can be manufactured easily and in a short time, and m
A decorative board with no defects such as bleeds, pinholes, or scratches was obtained, and by applying a lot of coloring, a unique pattern was created by the mottling as detailed below, and on the other hand. It is extremely visible outside the glass surface.

A specific manufacturing method will be described in detail below.

1 to 5 show cross-sectional views of mottled pattern formation.

The surface of a clean glass plate was sprayed with a transparent polyester polyurethane resin and a solvent consisting of ethyl acetate and rosol upatate so that the film thickness was uniform by a known method such as the spray method or the feather method. -liquid*
*For forming 2, immediately after coating 2, in a state where the coating film 2 maintains fluidity, a 2am colored acrylic polyurethane resin and a solvent consisting of toluene and xylene are applied thereon), a surfactant modifier. as silicone resin 0.5
% droplets of the second liquid) are scattered using four drops of dripping odor to form the colored portion 31. # Fi where the droplets of the second liquid spread on the first liquid m layer and the droplets of the second liquid do not connect with each other;
It is necessary that the second liquid is immiscible with the first liquid and the interfacial tension of the second Wi is higher than that of the second liquid.0 The two liquids are immiscible.
Different types of resin coatings must be used, such as alkyd resin for the first liquid, polyester polyurethane resin for the second liquid, or melamine resin for the second liquid.

It may also be a combination of the second l[K epoxy resins.

In addition, the K that makes the solvents of the first and second liquids compatible can be, for example, one liquid in ethyl acetate, cellosolve 7-, tate group, and the other in toluene, xylene, benylene group, or hexane, heptane, octane, etc. shall be.

(Continued on next page) Bottle 9, K with different transparency and color tone between the first and second liquids
In case 9, no organic dye is added to the second liquid, and in case of case 9, no organic dye is added to the second liquid, and a translucent and/or opaque inorganic pigment is added to the second liquid.

A surfactant modifier is usually added to reduce the internal tension between the second liquid and the second liquid. Examples of surfactant 5m11 agents include polyolefin wax, silicone resin, liquid paraffin, and 7-11*#6. For example, silicone resin exhibits its effect when O, OS- is added to the second liquid,
Although the interfacial tension decreases as the amount added increases, addition of 516 or more impairs the adhesion between transparent @*lI2 and the colored portion 5''.

The viscosities of the first and second liquids are similar.The spreadability of the second liquid is better. IA is good, however, if the viscosity is less than 10 seconds using a viscosity needle (Iwata type Zankappu), the fluidity is high and an IIO level am is required.

The thickness of the coating film depends on the relationship with the viscosity, but the dry thickness is around 30#, so it is not necessary to make it thick.
Sui needs a low viscosity liquid for the same reason!
J! unconventional.

The amount of the second liquid dropped depends on the size of the liquid viscosity unevenness and the amount of surfactant added, but usually the viscosity of the liquid is 15 seconds, the diameter of the unevenness is 3cm, the surfactant (silicon*yit>o, s*
It becomes 3000/m'' m antinodes at s addition.

The time for dropping the second liquid on the cloth is preferably within 10 minutes at room temperature, while the liquid remains sufficiently fluid, and the spreading process is completed after dropping the second liquid. , the time for the pattern to stabilize is within 5 minutes.

The second liquid may be sprayed or flowed down by a direct sprayer, flow coater, curtain coater, etc., but the second liquid may cover the entire surface of the coating film of the first liquid to obtain a desired mottled pattern. However, the above-mentioned dropping method is essential for pattern formation.
However, it is difficult to obtain a large number of colored patterns by using a second alt with a plurality of different color tones.

If you drop the liquid III from Part 2 at the same time at evenly spaced positions on the ridge, the pattern will be the same size, but if you drop it at different times, the spots that were dropped first will be larger even if the amount of drops is the same. , after the droplets are formed small. The great heat of the Dan-ku spot can also be adjusted by adjusting the amount of liquid dropped and the viscosity 19 at the interval between the irises and the lower part of the iris, and the shape of the p pattern can also be adjusted by a combination of these.

As shown in Fig. 4, the first trace appears as a grid pattern 2, and the second liquid forms a pattern as a mottled pattern 3I.
After the exposed pattern is formed, it is heated in a drying oven at 100-150°C.
The decorative board desired by the present invention can be obtained by passing #& for 10 to 15 minutes.

In addition, the substrate is applicable not only to glass plates but also to transparent plates made of acrylic and polyester plastics.

In addition, in order to prevent the occurrence of scratches etc. due to external factors on the colored part 2 of the coating film 2 and further improve weather resistance, a third liquid such as epoxy 11M resin, urethane resin, melamine 11& etc. - It may be formed in the genus 51, and by coloring the genus 1Ii, a variety of mottled patterns can be obtained by superimposing the colored pattern of the liquid on the genus G and II, creating an extremely *cowardly decorative effect. It is something that appears.

It was a platform. The first liquid is colorless transparent resin paint, the second liquid is talc, etc.
A colorless and semi-transparent resin paint is formed from these K, and the nine coatings are plated with silver and backed to give a glossy finish.
A decorative board is obtained which exhibits a K-silver surface and a pattern overflowing with a three-dimensional effect.

(Continued on next page) Next, let's talk about some examples. Examples! The main ingredient is a polyester polyol tree layer as the first liquid.
Solvents such as ethyl acetate and cerol tate 47.
A polyester polyurethane resin prepared by thoroughly stirring a 5% mulch liquid and a B liquid containing incyanate resin as a main ingredient and 25.0% of the same solvent as the mulch liquid, was washed and dried in advance to form a 9-size piece. S (10 m x 50 () w 6 cm thick) was coated onto the surface of a plate glass using a spray method so that the coating film thickness (dry film thickness) was 50 μm, and then immediately as the second liquid, acrylic polyol resin was used as the main ingredient. One color pigment 1.9X
i) A liquid containing 549% of agent 611, which is made of toluene and xylene, and a solvent SaZ similar to the liquid liquid containing isocyanate 11 as the main ingredient, and containing silicone,
Add 5X and stir well 9B11I [9 acrylic polyurethane*tr and 2nd liquid] Same as 2nd @ 0-, use for 2nd liquid - yellow instead of red pigment Using a pigment, 9 acrylic polycrethane resin was applied through a dropper, and each drop was dropped onto the coating film of the first liquid so that each drop had a volume of 0.06 mm.When this was dispersed using a dispensing device, each of the two liquids -, The two droplets of the broom are spread over the coating film of the first liquid, and form a pattern in the form of a pattern without intermixing and connecting with each other.9. Thereafter, this was dried in a drying oven at 100°C for 10 minutes to obtain a decorative glass plate with a mottled colored pattern.9.

In addition, in order to prevent the occurrence of scratches on the coating and to further improve the coloring effect, a white epoxy resin paint was applied, and the resulting decorative glass plate was dried for 1 second at 100°C.The resulting decorative glass plate had a red color. The border between the yellow and yellow mottled patterns was white, giving it a unique appearance.

Example 2 On a clean glass plate, the Kutoji Hoki-Shuku used in Example 1 was applied by spraying to form a coating film. Molten steel containing 69% xylene, 1.9% talc mold powder, 511.0% of a solvent similar to the liquid, 0.5% silicone resin added, and 9 B liquid mixed with stirring to create a mostly transparent acrylic. Boliureta/I1M fat liquid is sprinkled on the surface under the sun, left to stand for a few minutes, and then dried.The dried coating exhibits a mottled pattern with uneven transparent areas and translucent S. This was heated to 100℃ for 10
After drying *JG treatment, this film was then coated with a regular method, and after drying, it was painted with urethane resin for inking. As a result, a round decorative glass with a three-dimensional pattern with a glossy silver surface was obtained.
