本発明は建築物の内外装に用いられる貴金属色の光沢を
持つメタリ・ゾク調ほうろう製品に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a metal-like enamel product with a precious metal-colored luster that is used for the interior and exterior of buildings.

るとおり従来から知られている。(Prior art) Metallic pigments, which are made by coating the surface of mica powder with a thin film of metal such as titanium oxide to give a luster similar to that of precious metals, have been known for a long time, as shown in Japanese Patent Publication No. 3783/1983. There is.

易に得ることはできなかった。However, when this pigment is mixed with frit and used in enamel products, the metallic pigment is eroded during firing at 720 to 860°C, resulting in uneven color tone, making it impossible to obtain uniform and beautiful enamel products. . The inventors of the present invention attempted to solve this problem by suppressing the Rho component in the frit and creating a three-layer structure, but reducing the Rzo component makes it difficult to burn at low temperatures, resulting in poor workability, which does not meet the objective. It has not been possible to easily obtain enamel products with a uniform and beautiful appearance.

。In this way, the present invention uses a mica pigment in which a coating layer of alumina or zirconia is further formed on the surface of a conventional pigment. This coating layer is made by dispersing conventional powdered mica with a coating layer of titanium oxide or iron oxide in water, adding an aqueous solution of aluminum sulfate on the acid side of PI (3 to 4), and keeping it at 60 °C for 1 hour.

) 4 etc., and coating can also be carried out by a sol-gel method which is known per se. The film thickness is several micrometers
- is sufficient, and if it is too thick, it may hinder color development. The reason why alumina or zirconia is used as the material for the coating layer is that these have the function of effectively protecting the mica pigment from the RmO component in the frit.

を生じ易い。The mica pigment forming such an alumina or zirconia coating layer is preferably mixed into a glaze together with a transparent frit at a ratio of 1 to 15% (weight ff1) to form a metallic glaze. If the mica pigment is less than 1%, metallic color development is insufficient, and if it exceeds 15%, baking defects are likely to occur.

Prevented, 720~
Even if fired at 860'C, a metallic enamel product with a uniform and beautiful appearance can be obtained.

A lower glaze layer was formed by spraying glaze on both the front and back sides of a 00a, 6 part m iron plate and firing at 810°C for 4 minutes.Meanwhile, a metallic glaze was created by blending the raw materials as shown in the table on the next page. Pigment A in Table 0 is a mica pigment in which an alumina coating layer with a thickness of 3 μm is further formed on the surface of powdered mica having a titanium oxide coating layer.
In this example, a zirconia coating layer with a thickness of 2 μm was further formed on the surface of powdered mica having a coating layer of titanium oxide and iron oxide. In addition, as a frit, 510g 60%, Ti (h 6%, BxOs 10

In the case of E, the enamel product was extremely uniform and had a beautiful appearance. However, in Comparative Example 1 in which a conventional mica pigment was used as the pigment in the mill compounding tool A, and in Comparative Example 2 in which a conventional mica pigment was used as the pigment in the mill compounding tool, the surface became mottled.

Then, add this mica pigment to 1-15 (
Since the metallic glaze layer containing M)% is formed on the lower glaze layer on the surface of the iron plate, the alumina or zirconia coating layer prevents the mica pigment from erosion even during high temperature firing, resulting in a uniform and beautiful appearance. This is a metallic enamel product. Furthermore, these coating layers do not inhibit the color development of the mica pigment, resulting in an enamel product with a clear precious metal color.
