Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] In a broad sense, the present invention belongs to the field of manufacturing technology for architectural boards. Specifically, it belongs to the technical field of patterning and surface decoration of architectural boards. More specifically, among the patterning methods, it particularly belongs to the field of technology called water surface transfer method.

[Background technology] The water surface transfer method involves filling an aquarium with water and spreading paint on the water surface to form a paint film.
This is a technique that transfers this onto the surface of the object to be painted, and it has been practiced as a handicraft for a long time.

However, there are various problems with the patterning method using the water surface transfer method, and several techniques have been published as solutions to these problems. For example, patent no. 92949
No., JP-A-56-144281, JP-A-53-142448,
Various publications such as Japanese Patent Application Laid-open No. 100131/1984 disclose improved techniques for water surface transfer.

By the way, one of the important technical issues in the conventional water transfer method is to ensure the reproducibility of the pattern and make it suitable as a patterning method for mass-produced products, and the other is to improve the pattern color. The aim was to diversify the industry.

In the above literature, some attempts have been made to achieve mass production, but the reproducibility of patterns is still insufficient, and no proposals have been made regarding diversification of colors. Originally, the water surface transfer method, also known as the sumi-ryu method, was a method that could only express patterns using shading patterns of a single color.

[Purpose of the Invention] This invention was made in view of the above-mentioned circumstances, and aims to provide a water surface transfer method that is capable of achieving pattern reproducibility and expressing a plurality of color patterns. It was done as.

It should be noted that, of course, the reproducibility of the pattern referred to here does not refer to the reproduction of the same pattern in a strict sense, but refers to the degree to which the overall feel is similar.

[Disclosure of the Invention] This invention provides a patterning method using a water surface transfer method, in which, in addition to a so-called pattern design section, a compartment for storing a solvent and a compartment for storing a paint are provided, and a water-insoluble solvent is used as a carrier for the paint. It is characterized by the use of

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings shown as an example of an apparatus used in carrying out the invention.

The figure is a schematic diagram showing an example of an apparatus used in carrying out the present invention. In this diagram, 1 is the aquarium, 2
3 and 4 are paint supply means; 5 is a diffusion pattern developed on the water surface; 5a is a pattern design section; 6
7 is a construction board which is the object to be painted, 7 is a solvent supply section, 8 is
is the paint supply section, 9 is the first weir, 10 is the second weir, 11
is the third weir.

In the above apparatus, first, the water tank 1 is filled with water to an appropriate depth. Next, the solvent supply means 2 supplies the solvent to the solvent supply section 7 . The solvent used is one that is insoluble in water and floats on the water surface. This solvent serves as a carrier, so to speak, and is not intended to be used to dilute the paint to be used later. Here, the conditions required for this solvent are summarized as follows.

Must be insoluble in water.

The specific gravity should be 1.0 or less, and preferably 0.8 or more.

The surface tension should preferably be lower than that of the paint used.

The rate of volatilization is slower than that of the paint solvent used,
The boiling point is preferably about 150 to 200°C (at 760 mm or less).

The compatibility with the paint and paint solvent used should be as low as possible.

After the above solvent has been supplied, the second weir is opened to send a predetermined amount of solvent into the paint supply section 8, and then the paint is supplied by the paint supply means 3 and 4. By using a plurality of types of paint to be supplied here, for example, a plurality of types of paint with different colors, it is possible to diversify the pattern colors. Alternatively, so-called base paint and pattern paint may be used. The base paint is used to make the pattern formed by the pattern paint fixed and to make the contrast of the pattern paint clear.

In the above manner, the water-insoluble solvent, base paint, pattern paint, etc. coexist temporarily in the paint supply section 8. However, there is no restriction that two or more types of paints must be used.

Next, open the third weir and apply paint to the pattern design section 5a.
A flow pattern is formed by diffusing the solvent. At this time, a water-insoluble solvent serving as a carrier diffuses on the water surface according to its surface tension, and the paint is conveyed while being placed on this, forming a flow pattern. In this case, a stirring device may be used as an auxiliary means to help form the flow pattern, but essentially the pattern is formed by leaving the solvent as a carrier or the paint itself to diffuse. . By doing this, a reproducible flow pattern can be obtained.

Once the pattern has been developed to a sufficient size, it is transferred to a construction board. To transfer, the architectural board is inserted diagonally into the tank by holding down the architectural board so that the surface of the pattern on the water surface adheres to the surface of the board. Once the pattern is sufficiently familiar to the surface of the architectural board and has been transferred, it is removed from the tank. Next, the transfer is completed by drying this. For subsequent treatment, it is sufficient to follow conventional methods.

In addition, regarding technical matters necessary for water surface transfer other than those explained above, publicly known means, equipment, and methods shall be followed. In the above-mentioned apparatus, the transfer of water-insoluble solvents, paints, etc. is carried out by lifting the weir upward to connect the water surfaces, and then leaving it to their own diffusion. Note that the first weir 9 is not essential.

Examples will be described below.

Example 1 Acrylic resin paint (Dainippon Paint Co., Ltd.) was used as the paint.
Co., Ltd., red), and water transfer coating was applied to the slate board using equipment with the structure shown in the diagram. Note that toluene was used as the paint solvent. Ethyl benzyl ether was also used as a water-insoluble solvent.

Through the above implementation, a relatively wide striped pattern could be formed, and similar patterns could be obtained with good reproducibility. This could be transferred well onto the slate board.

Example 2 Red and yellow acrylic resin paints (same brands as in Example 1) were used as paints, and propyl alcohol was used as the solvent. Furthermore, silicone oil (manufactured by Shin-Etsu Chemical Co., Ltd.) was used as a water-insoluble solvent.

When the procedure described above was carried out using the apparatus shown in the figure, a narrow two-color stripe pattern was obtained with good reproducibility. Additionally, this pattern could be successfully transferred to a slate board.

[Effect of the invention] This invention divides the water surface into a solvent supply section and a pattern design section via a paint supply section by a weir, supplies a water-insoluble solvent to the water surface of the solvent supply section, and then The method included a step of transferring a fixed amount of paint to the paint supply section, then supplying the paint to the paint supply section, and then diffusing it to the pattern design section, so that the following effects could be obtained.

Since the water-insoluble solvent acts as a carrier, a reproducible flow pattern is formed.

Furthermore, for the reason described above, even if two or more colors of paint are used, a multicolored pattern is formed without being completely mixed during diffusion.
