る。Detailed Description of the Invention (Industrial Applications) The present invention is applicable to building materials, kitchen appliances, bathtubs, chemical factory supplies,
This invention relates to enameled stainless steel products such as r'I, and relates to a method for producing an enameled glaze that does not require special pretreatment and has excellent adhesion to the surface of stainless steel.
（従来技術とその問題点）
ステンレス鋼は錆難く耐食性に富み、永くその輝きを失
わないので、建築用内外壁、台所製品。(Prior art and its problems) Stainless steel is rust resistant, highly corrosion resistant, and retains its shine for a long time, so it is used for architectural interior and exterior walls and kitchen products.

ス鋼のほうろうがけが種々検討されてきたが、未だ充分
満足すべきものが得られていないのが現状である。It is used in many areas such as bathtubs, washbasin poles, and vehicles. However, along with its advantages, stainless steel also has the disadvantages of being very susceptible to rust, crevice corrosion, and stains caused by contact between dissimilar metals, and C! It has drawbacks such as being easily attacked by l- ions and not being able to be colored freely. Therefore, various methods of enameling stainless steel have been studied in the past as a way to further enhance the properties of stainless steel and at the same time eliminate these drawbacks, but the current situation is that nothing that is fully satisfactory has yet been achieved. .

要であるが、ステンレス鋼は通常の鉄ほうろう用釉薬の
焼成温度では、かなり安定で、釉薬が素地と反応し得る

と考えられていた。In other words, in order for the enamel glaze to have sufficient adhesion to the base metal, the base metal must be sufficiently oxidized at the firing temperature of the glaze, but stainless steel is considerably oxidized at the firing temperature of normal iron enamel glazes. It was thought that good adhesion could not be achieved because the glaze was stable and did not oxidize sufficiently for the glaze to react with the base material.

題がある。For example, the depth of the four parts is 80 to 400 pm on the stainless steel surface, and the concave roughness is 2 to 30 g.
It has been disclosed that the adhesion between stainless steel and glaze can be made more reliable by providing a concavo-convex pattern of z mechanically or chemically in one step (Japanese Patent Publication No. 52-1729). It is extremely difficult to form and confirm a concave roughness of ~30 μm. In addition, stainless steel is heated in advance in an oxidizing atmosphere to form an oxide film on its surface, and then immersed in an aqueous solution containing divalent nickel ions to uniformly adhere nickel ions to the oxide film. A method of strengthening the adhesion of the stainless steel and the glaze has been disclosed (Japanese Patent Publication No. 55-30588), but this method has a problem in that it requires about 21 hours of pre-treatment of the stainless steel.

There is a method of introducing 1 to 3 wt% of MOO into a frit component that can be fired at a relatively low temperature (Japanese Patent Publication No. 14819/1983), but this method involves directly baking a transparent glaze onto stainless steel. , a craft-like enamel product with a metallic luster pattern unique to stainless steel can be obtained, and its frit composition is also very specific.

一層の改良が望まれる技術分野である。Furthermore, 5 to 30 wt % of Fe2O was introduced into the glass mainly composed of borosilicate containing no fluorine component. An enamel frit with good adhesion to stainless steel has been disclosed (Japanese Patent Laid-Open No. 52-810), but this method introduces a large amount of Fe20 during the manufacture of the frit, which may cause contamination of the glass melting furnace or kiln. This is extremely uneconomical in frit production, and because of the large amount of Fe201 contained in the frit, Fe20ff can be reduced by repeated firing two to three times.
As mentioned above, stainless steel enamel cannot be said to be a perfected technology yet.
This is a technical field in which further improvement is desired.

い。The glaze obtained by milling is applied to a degreased stainless steel surface, and when fired at 700 to 900°C after drying, it forms an enamel layer with excellent adhesion to stainless steel. Because it has very good adhesion, it is sufficient to simply degrease the stainless steel surface as a pretreatment for glazing, and there is no need to roughen the surface by mechanical or chemical means as in the past. Not at all.

ｐ ） Ｎ ｏ １ （表３）を用意し、た。The reason why an enamel glaze with good adhesion to the steel surface is obtained by adding iron oxide as a mill additive is not due to the fact that the adhesion does not deteriorate even after repeated firing. I couldn't see it. The glaze of the present invention is Fe, 03
Because it contains a large amount of , it takes on a brownish color after firing. Therefore,
The final product consists of 71 pieces, with an upper layer of glaze applied on top to create a two-layer structure. The reason for limiting the addition h1 of iron oxide to 5 to 50 parts by weight in the present invention is that if it is less than 5 parts by weight, the adhesion between the stainless steel and the glaze is insufficient, and if it exceeds 50 parts by weight, the fire resistance of the glaze will decrease. It becomes impossible to fire under normal firing conditions, and stainless steel and yuzu,
This is because the adhesion of the medicine to the chopsticks decreases. Next, the present invention will be explained in more detail with reference to Examples (Examples).
