その製造法に関するものである。Detailed Description of the Invention (Field of Industrial Application) The aluminum enamel product of the present invention and its manufacturing method are characterized in that potassium titanate is added to the surface of metal aluminum, which has a melting point of 660°C, which is relatively low among metal materials. This invention relates to an enamel product made by melting and baking an enamel glaze containing fibers at a relatively low temperature, and a method for producing the same.
（従来の技術）
金属アルミニウムは錆難い材料として家庭用品
建築材料などに多用されている。しかし模様を彩

せいぜいであるので、近年、これにほうろう焼付
を行うことが盛んとなつた。(Prior Art) Aluminum metal is widely used as a rust-resistant material for household goods and construction materials. However, there are difficulties in coloring the patterns, and the best option is to anodize them, so in recent years, enameling has become popular.
ところが、純金属アルミニウムは融点が約660
℃であるのに対し、一般用ほうろう釉薬は融点が
650℃〜800℃位であるため、アルミニウム製品は

る。 However, pure metal aluminum has a melting point of approximately 660.
℃, whereas general-use enamel glaze has a melting point of
Unlike iron products, it is difficult to enamel aluminum products because the temperature is around 650℃ to 800℃.
In particular, various studies have been conducted on enamel glazes for metal aluminum. In order to lower the melting point of these enamel glazes, ingredients that lower the melting point of the enamel glaze are added, but these ingredients affect the corrosion resistance and wear resistance of the enamel after baking. It is normal for it to become damaged.
そこで耐蝕性、耐摩耗性などに優れた添加物、
例えば珪石粉、アルミナ粉などを加えて対処する
が、その場合、所定の表面を得るには焼成温度を
高くしなければならなかつた。 Therefore, additives with excellent corrosion resistance and wear resistance,
For example, silica powder, alumina powder, etc. are added to solve this problem, but in that case, the firing temperature must be increased to obtain the desired surface.
耐熱性のある鉄系金属表面においても、焼付の
際高温で加熱すると加熱変態による歪を鉄系金属
に生ずるので、鉄系金属に対してもより低温の焼
付ができれば望ましいことである。 Even on the surface of a heat-resistant iron-based metal, if it is heated at high temperatures during baking, distortion will occur in the iron-based metal due to thermal transformation, so it would be desirable to be able to bake the iron-based metal at a lower temperature.

るには特別なほうろう釉薬と特定な無機繊維との
組合せが必要なのである。 Here, inorganic fibers are used in the heating process of general enamel glaze at temperatures of 700℃ to 930℃ to reduce air bubbles, prevent giant bubbles, and improve color stain resistance, scratch resistance, and mechanical impact resistance. Some of them are mixed in (Japanese Patent Application Laid-Open No. 57-88041). However, all of these products are for use in carbon steel plates, and their baking temperatures are all 700°C or higher, which does not solve the problem that the present invention aims to solve. Enameling on metal surfaces with low melting points, such as metallic aluminum, requires a combination of special enamel glazes and specific inorganic fibers.

The purpose is to bake the frit alone at an appropriate temperature and to obtain a product with good corrosion resistance.

寄与するところ大なものがある。(Effects of the Invention) The aluminum enamel product of the first aspect of the present invention is obtained by applying a phosphoric acid-based enamel glaze containing potassium titanate fibers and a phosphoric acid-based enamel frit to the surface of metal aluminum, and at a temperature of 600°C or less. Among them, P 2 O 5 ,
40-75% by weight; Al2O3 , 3-26% by weight; Na2O +
K 2 O + Li 2 O, 6-26% by weight; MgO + ZnO +
A metal aluminum surface is glazed with an enamel glaze containing an enamel frit containing TiO 2 , 7.5 to 26% by weight as a main component, and potassium titanate fibers,
The method for manufacturing aluminum enamel products according to the second invention of the present invention is to apply a phosphoric acid-based enamel glaze slip on the surface of metal aluminum,
The essential structure is to spray fine potassium titanate fibers onto the surface while it is still wet, allow it to adhere, dry it, and bake it.
In addition to metal aluminum surfaces, which have a melting point of approximately 660℃, enameling can also be applied to heat-resistant ferrous metal surfaces, and even though they are baked at low temperatures, they are corrosion resistant, wear resistant, and easy to clean. With the advent of such enamel glazes, it has become possible to obtain enamel surfaces on aluminum metal surfaces that have the same corrosion resistance and wear resistance as ferrous metal surfaces. The present invention greatly contributes to the development of industry.
