It is sectional drawing which shows the state which is implementing the formation method of the metallic tone coating layer in embodiment of this invention (Example 4). It is a perspective view which shows the implementation state of the formation method of the metallic tone coating layer in other embodiment of this invention (Example 5).

In the figure, the metallic coating layer 1 comprises 40 to 55% by weight of varnish resin, 30 to 45% by weight of butyl acetate, 1 to 10% by weight of propylene glycol monomethyl ether acetate and xylene with respect to 100 parts by weight of the metal fine powder 2. 23 ± 5 parts by weight of binder 3 based on 1 to 5% by weight, and 2.4 ± 0.4 parts by weight of activator 4 (described in detail later) for activating this binder 3 The surface treatment agent 5 containing parts is applied to the surface of the substrate 6 and dried, and the content of the metal component in the coated surface treatment agent 5A after drying is at least 90% by weight or more. . Then, as shown in FIG. 1, the surface treatment agent 5 is charged with a binder 3 and an activator 4 in a mixing container 7, and after mixing both agents for at least 3 minutes, the metal fine powder 2 is added to the mixture. Slowly add and mix to avoid “dama”.

  The metal fine powder 2 can be made into a fine powder of at least 0.1 to 50 μm, for example, and does not settle early in the mixed solution of the binder 3 and the active agent 4, and is in a floating state for at least about 2 minutes. If it is a metal which can continue, there will be no limitation in particular. However, the metal fine powder 2 is preferably a metal selected from at least one of iron, stainless steel, copper, bronze, brass, zinc, and aluminum. The reason is that it is a commonly used metal, is distributed in large quantities, can be easily obtained, and is advantageous in terms of cost. There are two types of brass, silver type and gold type, both of which are used.

  Since the specific gravity of the metal fine powder 2 varies depending on the selected metal species, the fineness of the metal powder 2 also varies. For example, among the metal species of the metal fine powder 2 described above, those with higher specific gravity are related to copper, bronze, and brass with about 8.6, and those with lower specific gravity are about 2.7 aluminum. Related. Therefore, copper, bronze, and brass-related metal species having a high specific gravity have a fineness approaching 0.1 μm, and aluminum-related metal species having a low specific gravity have a fineness approaching 50 μm. The fineness of the metal fine powder 2 varies depending on the thickness of the metallic coating layer 1 to be formed. For example, although the thickness of the metallic tone coating layer 1 is 5 μm, the fineness of the metal fine powder 2 is never 5 μm or more.

  As described above, the binder 3 is mainly composed of 40 to 55% by weight of varnish resin, 30 to 45% by weight of butyl acetate, 1 to 10% by weight of propylene glycol monomethyl ether acetate and 1 to 5% by weight of xylene. Ingredients. Therefore, the binder 3 determines any weight percent of the varnish resin from the range of 40 to 55 weight percent. Similarly, butyl acetate, propylene glycol monomethyl ether acetate, and xylene are determined to have a weight percentage of 100% by weight as a whole by determining any weight% from the respective weight% ranges. It should be noted that each substance in the binder 3 should not deviate from the range of these weight percentages. If it deviates from the range of these weight percentages, the function as the binder 3 cannot be performed. For example, even if the surface treatment agent 5 is applied to the surface of the substrate 6 and dried, the content of the metal component in the content of the metal component in the coated surface treatment agent 5A after drying may not be 90% by weight or more. Conceivable.

  As described above, the activator 4 is for activating the binder 3, and butyl acetate is 40 to 55% by weight, 1,6-hexamethylene diisocyanate homopolymer is 40 to 55% by weight, bis [3- (Trimethoxysilyl) propyl] amine is mainly composed of 1 to 5% by weight. Accordingly, activator 4 determines any weight percent of butyl acetate from the range of 40 to 55 weight percent. Similarly, 1,6-hexamethylene diisocyanate homopolymer and bis [3- (trimethoxysilyl) propyl] amine are approximately 100% by weight as a whole, with any weight% determined from the respective weight% range. To be. It should be noted that each substance in the activator 4 should not deviate from these weight percent ranges. If it deviates from the range of these weight percentages, the function as the active agent 4 cannot be performed. For example, even if the surface treatment agent 5 is applied to the surface of the substrate 6 and dried, the binder 3 cannot be activated, and the applied surface treatment agent 5A after the drying becomes brittle and easily peels off. It is conceivable that the content of the metal component in the coated surface treating agent 5A does not exceed 90% by weight.

  As described above, the surface treatment agent 5 is 23 ± 5 parts by weight of the binder 3 with respect to 100 parts by weight of the metal fine powder 2 and the activator 4 for activating the binder 3. Of 2.4 ± 0.4 parts by weight. Therefore, the surface treatment agent 5 is at least 18 parts by weight of the binder 3 and 2.0 parts by weight of the activator 4 with respect to 100 parts by weight of the metal fine powder 2. For this reason, the surface treating agent 5 is 100 + 18 + 2.0 = 120.0 parts by weight in the minimum total amount. On the contrary, the surface treatment agent 5 has a maximum of 28 parts by weight of the binder 3 and 2.8 parts by weight of the activator 4 with respect to 100 parts by weight of the metal fine powder 2. For this reason, the surface treating agent 5 is 100 + 28 + 2.8 = 130.8 parts by weight in the maximum total amount.

  Moreover, as described above, the surface treatment agent 5 is applied to the surface of the substrate 6 and dried, and then the coating surface treatment agent 5A after the drying, that is, the content of the metal component of the metallic tone coating layer 1 is at least. It is 90% by weight or more. Therefore. The surface treatment agent 5 corresponding to at least 100% by weight-90% by weight = 10% by weight is volatilized in the soot that is formed by forming the metallic coating layer 1. From the component which comprises the surface treating agent 5, since the metal fine powder 2 does not volatilize, a part of binder 3 and the activator 4 will volatilize. For example, when the total amount of the surface treatment agent 5 is 100 + 18 + 2.0 = 120.0 parts by weight, 120.0 parts by weight—100 parts by weight of the metal fine powder 2 = 20.0 parts by weight of the binder 3 and the activator 4 A part of is volatilized. That is, when the content of the metal component in the metallic tone coating layer 1 is 90% by weight, 100 parts by weight of the metal fine powder 2 / 0.9 = 111 parts by weight, and 120.0 parts by weight-111 parts by weight = 9. The binder 3 and the activator 4 corresponding to 0 part by weight will volatilize.

  When the surface treatment agent 5 is the maximum total amount of 100 + 28 + 2.8 = 130.8 parts by weight, 130.8 parts by weight—100 parts by weight of the metal fine powder 2 = 30.8 parts by weight of the binder 3 and the activator 4 A part of is volatilized. That is, when the metal component content of the metallic tone coating layer 1 is 90% by weight, 100 parts by weight of the metal fine powder 2 / 0.9 = 111 parts by weight, and 130.8 parts by weight−111 parts by weight = 19.8. The binder 3 and the activator 4 corresponding to parts by weight will volatilize. Therefore, even if the surface treatment agent 5 is the maximum total amount, the binder 3 and the activator 4 corresponding to 19.8 parts by weight are volatilized, and the volatilization of the binder 3 and the activator 4 is compared with that of the prior art. The amount to be done is drastically reduced and the safety is correspondingly high.

  The base material 6 is not particularly limited as long as the above-described surface treatment agent 5 can be applied. For example, plastic materials, wood, concrete, glass, various boards, metal materials, and the like can be used. .

Next, a procedure for forming the metallic tone coating layer 1 on the surface of the substrate 6 using the surface treatment agent 5 having the above-described configuration will be described.
First, the ratio of 23 ± 5 parts by weight of the binder 3 and 2.4 ± 0.4 parts by weight of the activator 4 for activating the binder 3 with respect to 100 parts by weight of the metal fine powder 2. A binder 3 and an activator 4 are prepared. The prepared binder 3 and activator 4 are put into a mixing container 7, and after mixing both agents for at least 3 minutes with a stirrer, the metal fine powder 2 is gradually added to the mixture so that it does not become "dama". The surface treating agent 5 is prepared by adding and mixing. Next, the foundation | substrate confirmation of the base material 6 surface of arbitrary shapes is performed. For example, if the surface of the base material 6 is smooth and dry, or if there is no wiping residue such as a solvent, etc., and if it is desired to finish the metallic coating layer 1 completely and vividly, a known metal It is better to apply a primer with a primer.

  After finishing the base preparation such as confirmation of the surface of the base material 6 and applying the ground treatment, the surface treatment agent 5 prepared above is applied to the surface of the base material 6 using an applicator such as a brush, a roller or a palette knife. Apply. After the application, the binder 3 and the activator 4 in the coating surface treatment agent 5A are 9.0 parts by weight / 20.0 parts by weight = 0.450 to 19.8 parts by weight after naturally drying for 12 to 24 hours. Parts / 30.8 parts by weight = 0.643 is volatilized, and after drying, the metallic coating layer 1 having a metal component content of at least 90% by weight or more is obtained. Thereafter, the metallic tone coating layer 1 is polished and polished as necessary to complete the forming operation of the metallic tone coating layer 1.

  In addition to application tools such as brushes, rollers and pallet knives, application by a spray gun is also possible. In this case, particularly in the summer, the binder 3 and the activator 4 are combined with a coagulation retarding agent 8, for example, Then, after adding diacetone alcohol, etc., and mixing them carefully, care should be taken so that the fine metal powder 2 does not become “dama” in the same way as above, and mixed gradually. The surface treatment agent 5B containing the coagulation retarder 8 is prepared. Thereafter, the surface treatment agent 5B produced as described above is applied to the surface of the base material 6 for which the base adjustment has been completed with a spray gun. The application of the surface treatment agent 5B by the spray gun is particularly useful when the surface of the substrate 6 has many irregularities.

  Further, as described above, the completed metallic-tone coating layer 1 has a metal component content of at least 90% by weight or more, so that the characteristics are unique to the characteristics of the contained metal species, that is, each metal itself. The texture will appear as it is. Therefore, the contained metal species that are likely to rust naturally rust, and conversely, if the contained metal species is iron or copper, especially copper, it is possible to express a change in texture over time.

  The finished metallic tone coating layer 1 is preferably polished and further polished. That is, the surface of the coated surface treatment agent 5A after drying is polished, at least a part of the binder 3 remaining on the surface is removed, and the metal component in the coated surface treatment agent 5A is bare and necessary. The coated surface treatment agent 5A is polished according to the above. The above polishing is performed manually if the surface area is less than 1 m2, for example, and if it exceeds 1 m2, a polishing machine may be used. The polishing method is performed using a known means such as sandpaper, fine steel wool, or sanding fleece. Also, polish the surface with a known polishing pad using a known polishing paste or nano wax, and then polish the remaining polishing paste or nano wax on the surface with a soft cloth. Do this by wiping.

  Also, if there is a specific part to be particularly emphasized on the surface of the metallic tone coating layer 1, the specific part to be emphasized is particularly carefully polished, and other parts are polished with little or no polishing and specified with emphasis. Alternatively, the emphasized specific portion may be conspicuous, and conversely, the emphasized specific portion may be polished moderately or not polished at all, and other portions may be carefully polished to make the emphasized specific portion conspicuous. Even in this case, the above-described polishing is performed.

Since it verified whether the content of the component contained in the metallic tone coating layer 1 was at least 90% by weight, the situation is shown.
<Test Example 1>
Add 23 g binder, 2.4 g activator to the mixing vessel, stir and mix for 3 minutes, gradually mix 100 g stainless steel fine powder into this mixture, and add stainless steel surface treatment agent. Make it. The surface treatment agent of stainless steel produced on the base material of the wood plate is applied with a brush, the applied surface treatment agent is dried at a room temperature of about 20 ° C. for 20 hours, and the dried applied surface treatment agent is applied. Scrape off with about 1g. The weight of the dry-coated surface treatment agent thus scraped off is accurately weighed, put in a high-temperature chamber of about 400 ° C., taken out 30 minutes later, left for 30 minutes, and then weighed accurately. Then, it is determined whether the content of the stainless steel component contained in the metallic tone coating layer is at least 90% by weight or not from the difference between before entering the high temperature chamber and after taking out from the high temperature chamber.
<Test Example 2>
Except for replacing 100 g of the stainless steel fine powder of Test Example 1 with 100 g of gold-type brass, the test was conducted in the same manner as in Test Example 1, and the content of the gold-type brass component contained in the metallic coating layer was at least It is determined whether it is 90% by weight or more.
<Test Example 3>
Except that 100 g of the stainless steel fine powder of Test Example 1 is replaced with 100 g of zinc, the test is performed in the same manner as in Test Example 1, and the content of the zinc component contained in the metallic coating layer is at least 90% by weight or more. Judge whether or not.
The results are shown in Table 1.

表１によれば、乾燥後の塗布表面処理剤における金属成分の含有量はいずれも、９０重量％以上であり、本発明の有利性が検証された。

According to Table 1, the content of the metal component in the coated surface treatment agent after drying was 90% by weight or more, and the advantages of the present invention were verified.

  Further, as shown in FIG. 3, the metallic tone coating layer 1 described above is formed in advance on a sheet 9 that can be bonded to the base material 6 to produce a metallic tone sheet 10. If this metallic tone sheet 10 is bonded to the base material 6, the surface of the base material 6 can be easily made metallic, and it is very convenient. That is, the surface of the base 6 can be made metallic by simply bonding the metallic tone sheet 10 to the surface of the base 6, and most of the steps for forming the metallic tone coating layer 1 on the surface of the base 6 are omitted. Because it will be possible.

  Also, as shown in FIG. 4, the metallic tone sheet 10 described above is prepared by pasting the metallic tone sheet 10 on the base material 6 in advance. If this metallic decorative panel 11 is used for an interior material, an exterior material, or a ceiling material, it is convenient that those used places can be easily made metallic. That is, it is possible to make them metallic by simply using the metallic decorative panel 11 as an interior material, exterior material, or ceiling material, eliminating the need to attach the metallic sheet 10 to the surface of the substrate 6 described above. Because it will be possible.

  Further, as shown in FIG. 5, an object 12 designed in an arbitrary shape may be bonded to the surface of the base material 6 and the metallic coating layer 1 described above may be formed thereon. The object 12 in the method of forming the metallic tone coating layer 1 is not particularly limited, and for example, a previously created pattern or a commercially available pattern sticker may be pasted on the flat substrate 6 surface, You may affix the modeling thing by a three-dimensional copy on the base material 6 surface. Furthermore, based on the graphic arts and modeling object data stored in the computer, the computer art creates the graphic arts and modeling object using a conventionally known creation device, and affixes them to the surface of the substrate 6. It may be something like this. Therefore, even if the surface of the base material 6 is designed in an arbitrary shape, it can be easily made metallic.

  And since the object 12 of arbitrary shapes is bonded together on the surface of the base material 6 as shown in FIG. 6, and the metallic tone coating layer 1 is formed on them, the metallic tone coating layer 1 located on the object 12 is formed. The part is raised more than other parts. Since the raised portion 12A is also a portion to be emphasized in design, for example, when the polishing of the metallic tone coating layer 1 of the raised portion 12A is made stronger than the other metallic tone coating layer 1 portion, the metallic portion located on the raised portion 12A is used. A boundary is formed between the tone coating layer 1 and another metallic tone coating layer 1 portion, the rising portion 12A becomes a positive portion, the other portion becomes a shadow portion, and the metallic tone coating layer 1 portion on the rising portion 12A Will appear and emphasize. Therefore, the metallic-tone coating layer 1 portion on the raised portion 12A can give a strong impression to the viewer. Even in this case, needless to say, the above-described polishing is performed on the rising portion 12A.

  And as shown in FIG. 7, the said base-material 6 surface itself may be formed in the state designed in arbitrary shapes, and the above-mentioned metallic tone coating layer 1 may be formed on them. This method of forming the metallic tone coating layer 1 is particularly useful when the designed base material 6A itself is close to a dish-like art work. Even if it is a dish-like art work, it is based on the data of a dish-like art work stored in the above-mentioned computer, and the above-mentioned one-piece dish-like work is performed by a conventionally known creation device according to the command of this computer. An art work may be embodied on the base material 6A itself. After that, by forming the metallic-tone coating layer 1 on the base material 6A that embodies a dish-like art work, the dish-like art work can be easily made metallic. In this case, it goes without saying that the above polishing and polishing are performed.

  While the first to fifth embodiments of the present invention have been described above, it should be understood that the specific configuration is not limited to this, and that modifications within the scope of the present invention can be made as appropriate. .

  The metallic-tone coating layer of the present invention, the metallic-tone sheet and decorative plate thereof, and the method for forming the metallic-tone coating layer are not influenced by the shape of the base material desired to be metallic, and have a unique texture created by various metals themselves. When it is possible to express a change in texture over time and to reduce harmful solvents as much as possible, the applicability becomes extremely high.
