Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] This invention belongs to the field of painting technology, and more specifically belongs to the field of technology of patterning by water surface transfer method.

[Background technology] In the water surface transfer method, an aquarium is filled with water, and on the water surface,
It is a technique in which the paint is diffused to form a film of paint, and the object to be painted is applied to the surface of this paint film to transfer the paint film to the surface of the object to be painted. It has been practiced since ancient times. Although this method has the disadvantage that the degree of freedom in the pattern obtained is low, it has the advantage that it can coat objects of any shape, whereas general coating methods can only be applied to flat surfaces. was purchased and is still in use today. Therefore, as a method of applying wood grain decoration to the surface of small plastic molded products with many curved surfaces,
The water surface transfer method was applied.

However, as mentioned above, makeup using the water surface transfer method can only be applied to paints with wood grain patterns, and cannot be applied to makeups with other patterns. The reason for this is that the paint used in this case is highly viscous with almost no fluidity, and is pulled out through comb-shaped slits placed on the water surface and diffused onto the water surface. It depends on the situation. The reason why a high viscosity paint is used here is to prevent the paint from spreading more rapidly than through the comb-shaped slits, and there is also the reason that the desired wood grain pattern can be formed by doing so. Ta. However, because of this, it is not possible to control the extent to which the pattern spreads, or the pattern is determined by the shape of the slit, and because the flow only flows in one direction, it is not possible to obtain a woodgrain pattern, and the boundaries of the pattern are too clear. This resulted in disadvantages such as the ability to obtain patterns that lacked a natural feel. Regarding these technical deficiencies, there is no evidence that much effort has been taken to improve them, and there are not many recent documents on direct improvement techniques. However, in order to overcome the drawback that it can only be applied to wood grain patterns, an arbitrary pattern is printed on a polyvinyl alcohol film, the pattern printed on the polyvinyl alcohol film is floated on the surface of water, and the object to be coated is coated. A method of dipping and transferring has been proposed (Japanese Unexamined Patent Publication No. 5
5-61492). This method is a water surface transfer method that can also be called a film transfer method, and the techniques related to this pupil area are, for example, Japanese Patent Application Laid-Open No. 51-21911, Japanese Patent Application Laid-open No. 55
-4] [83] and Japanese Unexamined Patent Publication No. 57-110fl.

However, the above method has one more step than the normal water surface transfer method, making the water surface transfer method complicated and increasing the cost. In the first place, the advantage of the water surface transfer method was its low cost, so there was no point in unnecessarily complicating the painting process.

[Object of the Invention] The present invention has been made in view of the above-mentioned circumstances, and provides a water surface transfer method that can express any pattern with good reproducibility without sacrificing the advantages of the water surface transfer method. It was done with the purpose of

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 is an improved method for patterning using a water surface transfer method, which is characterized in that a paint film is formed on the water surface and then a paint is further applied thereon to form a pattern. The present invention provides a water surface transfer method.

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.

FIG. 1 is a schematic cross-sectional view (A) and a perspective view (B) showing an example of an apparatus used to carry out the present invention. In this diagram 1
is the water tank, 2 is the water surface, 3 is the paint reservoir, 4 is the pattern development part, 5
is a weir, 6 is a base paint supply device, 7 is a handle paint supply device,
8 is a base paint, 9 is a pattern paint, 10 is a substrate, and 11 is a transfer portion.

Here, only the main parts of the water tank 1 are shown. There is no need to prepare anything special for the aquarium 1. The conventional one is sufficient. This water tank 1 is filled with water to form a water surface 2. Then, the water surface 2 is divided into a paint reservoir part 3 and a pattern development part 4 by a weir 5.
Classified into Conventionally, there has been no example of clearly dividing the water surface 2 in this way. The 20 divisions of the water surface by the weir N are realized by submerging the lower end of the weir 5 below the water surface 2 so that the paint to be supplied later does not fall into the pattern development part 4. This weir 5 can be opened and closed freely. The means for this purpose are not limited. However, the weir 5 can be opened and closed freely as a device that makes it possible to pull up the entire weir 5 to open it, and conversely pull down the entire weir 5 to sink the lower end of the weir 5 below the water surface 2. It is most convenient to do so.

A paint supply device (eg, base paint 8) is arranged near the paint reservoir 3. This supplies the paint to the paint reservoir 3. Any number of paint supply devices may be installed.

When setting a pattern δ1 of multiple colors using multiple paints, multiple paints can be used. This is an additional effect of this invention. Conventionally, such a water surface transfer method using a plurality of colors or types of paints has not been proposed.

In the embodiment shown in FIG. 1, the base paint 8 is arranged so as to be able to supply the paint to the paint reservoir 3, and a pattern paint supply device 7 is further arranged above the pattern developing part 4. The base paint 8 serves as a base for multi-colored patterns,
This is diffused into the pattern development section 4 to form a coating film, and a pattern coating material 9 is supplied onto this from the pattern coating supply device 7 to form an arbitrary pattern. The base paint 8 is used with the aim of creating a pattern in which the pattern paint 9 is scattered in various patterns in the coating film of the base paint 8. That is, the base paint has the function of fixing the pattern formed by the pattern paint and clarifying the contrast of the pattern of the pattern paint.

These paint supply devices are provided with appropriate valves so that the supply of paint can be adjusted freely. In addition, base paint 8
A plurality of types of pattern paints 9 may be used, and in this case, care should be taken to use paints that are difficult to mix with each other so that they do not mix uniformly. In other words, there is no point in using multiple paints if they are completely compatible. In addition, the paint used,
In particular, it is desirable that the viscosity of the pattern paint 9 be sufficiently low that it can be spread on the water surface 2 by itself.

In addition, by changing the type of paint vehicle and the type of solvent used, paints with different degrees of diffusion on the water surface were adjusted, and the order of supply, amount of supply, and position of supply (in the paint reservoir) were adjusted. ), various patterns can be designed by adjusting. In particular, by adjusting the diffusion speed at the water surface, active movements such as spreading and repulsion of paint occur, so different paints form a pattern with an approximately even distribution, and patterns made of two or more types of paint are designed. can. Note that this also applies to the relationship between the base paint 8 and the pattern paint 9.

After completing the preparation as described above, the weir 5 is opened and the paint is spread on the water surface 2. When the weir 5 is opened and the water is chirped, the spreading force causes the paint to spread to the pattern development area 4 on the water surface 2, forming a coating film of the base paint 8. In this case, if two or more types of paint are used as the base paint 8, the pattern coating film can be formed even with the base paint 8 itself.

When the paint is spread over a sufficient area and the pattern 12 is formed,
If pattern paint 9 is added on top of this, the patterns will become even more diverse. Note that the pattern paint 9 may be applied to the area where the base paint 8 is spreading. The means for supplying the pattern paint 9 used here is not particularly limited. A method of simply dripping may be used, or a spray may be used. Further, these may be made into movable devices as appropriate. Although the patterns formed in this way have different external shapes, they have similar tastes and are diverse.

The pattern arranged as described above is transferred to an arbitrary object to be coated, here the substrate 10. To transfer, the substrate 10 is inserted diagonally into the tank while being pressed down with the substrate 10 so that the surface of the pattern on the water surface adheres to the surface of the substrate 10, which is the object to be coated, for example. Enough pattern on the board 10
Once it is familiar with the surface and has been transferred, remove it from the tank.

This transfer method is the same as the conventional method. However, this does not mean to limit the transfer method to the conventional method. As a result of the transfer, the pattern 12 is attached to the surface of the substrate 10 and a transfer portion 11 is formed. When the transfer is completed, the pattern 12 is removed from the tank. The finished product is then subjected to post-processing such as drying and final painting in accordance with the trial decision. There is no limit to the number of ships that can perform such auxiliary work.

FIG. 2 is a process diagram for explaining the contents of this invention in more detail. Diagrams A to E show the progress of the process.

First, Figure A shows a state in which the weir 5 is lowered into the water tank 1 to separate the paint reservoir section 3 and the pattern developing section 4. Then, the base paint supply device 6 and the base paint are prepared.

Next, the base paint is supplied, and the supplied paint 13 is stored in the paint reservoir 3. Diagram B shows this state.

Here, two or more kinds of base paints 8 may be used. These &J use paints that do not mix completely or are sometimes incompatible with each other. This is where the pattern is designed. Therefore, this is also a pattern design department. Here, multiple incompatible paints are pooled and then easily stirred (although this is not essential), creating a non-uniform mixing state. In this case, the pattern can be designed by adjusting the mixing state or selecting the compatibility, color, specific gravity, amount of paint used, type of solvent, amount used, etc.

Patterns can also be designed by adjusting the timing of supplying a plurality of base paints 8 and the time (setting time) from supplying the base paints 8 to opening @5. Patterns can also be designed by selecting the arrangement of a plurality of supply devices for roughly supplying a plurality of paints. In other words, in the paint reservoir 3, the dropping positions of two or more types of paint to be supplied are changed appropriately. For example, the distribution of two or more types of paints to be used is adjusted by randomly arranging the plurality of base paint supply devices 6, and in this state, the weir 5 is opened. In this way, it is possible to diffuse the particles while maintaining their distribution to a certain extent, and to design a desired flow pattern.

The figure shows a state in which the weir 5 is pulled up and the paint reservoir 3 is opened. When the weir 5 is opened, the pooled paint 13 is relatively rapidly diffused into the pattern development section 4 to form the planned pattern 12.

Next, the pattern paint is dripped onto this developed pattern by the pattern paint supply device 7. And the desired pattern is obtained. In this case, various patterns can be designed depending on the selection of the pattern paint supply means, the arrangement and number of pattern paint supply devices 7, whether the device is movable, and the type of pattern paint used.

In the end, what kind of pattern will be obtained by what kind of treatment will be determined empirically through trials. However, the result is sufficiently reproducible insofar as it is a uniformly random pattern.

Next, the pattern obtained as described above is transferred to the object to be painted. The pattern is attached to the object to be painted with the paint film tank turned upside down. However, such reverse transfer is not the only transfer state of the present invention. Figure E is a diagram showing the state in which a pattern is transferred to the substrate 10. Although this invention has been explained based on a special method of forming a diffusion coating film, this invention is a diagram showing a state in which a pattern is transferred to the substrate 10. The gist is to form a pattern by further supplying paint on top of the water surface, and therefore, applying paint on top of the paint film formed by the conventional method on the water surface also belongs to the pupil part of this invention. It is something.

In addition, regarding the technical matters necessary for water surface transfer other than those explained above, it is sufficient to follow known means, equipment, and methods.

Next, this will be explained in more detail with reference to Examples.

Example 1 FIG. 3 is a schematic diagram showing an example. (A) is a schematic plan view of the device, and (B) is a perspective view of the substrate 10 provided with a pattern. In this device, as shown in the figure, a base paint supply device 6 is disposed above a paint reservoir 3, and a plurality of pattern paint supply devices 7 are disposed randomly above a pattern development section 4. The base paint used in this example was UV paint (off-white) manufactured by Nippon Paint Jun, and Kijirol was used as the solvent. The former was used with an IQ wt% of 90 wt% and the latter was 90 wt%.

In addition, as the pattern paint, we used UV paint (sand beige) manufactured by Nippon Paint Jun, and as the solvent, we used a mixed solvent of ethyl acetate and Kijirol (the former 80 wt%, the latter IQ w).
t%) was used. The paint was formulated to use 10wL%.

When the pattern was designed in the above manner, a pattern was obtained in which the patterned paint pattern 15 was developed in streaks on the base paint film which was distributed approximately evenly as shown in the figure. When this was transferred onto the substrate 10, a substrate 10 with a water surface transfer pattern was obtained.

In this case, even if the process is repeated, a pattern that is roughly similar and has the same taste will be obtained, and will not be uniform or artificial.
The pattern has been changed to give it a more natural feel.

Example 2 Using the apparatus shown in FIG. 4(a), a pattern different from that in Example 1 could be designed by simply changing the solvent used.

Here, as a base paint, UV paint made by Nippon Paint Jun is used.
1Qwt% of paint (off-white) was used, and 9Qwt% of Kijirole was used as a solvent.

As the pattern paint, 1 wt% of UV paint (sand beige) manufactured by Nippon Paint Jun was used, and the solvent was 90 wt% of ethyl acetate. A relatively circular, cloud-like pattern 16 as shown above was obtained. When this was transferred, a substrate 10 having a similar transferred pattern 16 was obtained.

This water surface transfer pattern could also be obtained with good reproducibility. Moreover, it was not uniform and had a rich natural feel.

[Effects of the Invention] This invention is characterized in that a pattern is formed by further applying paint on top of the paint film that is diffused and formed on the water surface, so any pattern can be made into a diverse pattern with high reproducibility. It has the advantage of being able to express itself well.
