マイト建材に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alumite building material, and more particularly to an alumite building material having excellent corrosion resistance and cosmetic properties such as gloss, color tone and design, and particularly having a beautiful lacquer appearance.

Description of the Related Art Conventionally, in this type of anodized building material excellent in corrosion resistance and aesthetics, buffing of the anodized film (alumite) layer is performed by buffing, and clear coating or electrodeposition coating is used for polishing. A method is known, in which buffing, chemical polishing or electrolytic polishing of an aluminum base metal is performed, and then an anodized film layer is formed to impart gloss.

た部分をも削り取ってしまう結果となり、耐食性を著し
く低下させるという問題がある。また、バフ目が粗いた
め、研磨跡が残り美観においても自ら限界がある。However, in the above method, when the anodic oxide film is buffed at a high speed, the anodic oxide film layer is largely dropped off due to the rough buffing, and the portion subjected to the angle-sealing treatment is also scraped off. Therefore, there is a problem that the corrosion resistance is significantly reduced. In addition, since the buffing is coarse, polishing marks remain and there is a limit in terms of aesthetics.
【０００４】次に、の方法においては、耐久性が不充
分で、従って、美観を保つには頻繁に塗装をし直す必要
があり、メンテナンスが厄介であるという問題がある。In the next method, there is a problem that the durability is insufficient and therefore it is necessary to repaint frequently to maintain the aesthetic appearance, and maintenance is troublesome.

る程、光沢が減失するという問題を孕んでいる。According to a further method, since the anodized film itself is semi-transparent, the gloss of the bare metal ground by polishing is reduced by the film, and the thicker the film in order to improve the durability, the more gloss is obtained. There is a problem of loss.

い憾みがある。On the other hand, lacquer has a deep artistry that cannot be obtained by coating films of other paints, but it is expensive, has a high level of skill in coating technology, and its supply amount is decreasing year by year. However, there is a problem that it is difficult to use in the construction material field, which consumes a large amount.

マイト建材を提供するものである。SUMMARY OF THE INVENTION In view of the above situation, the present invention provides an alumite building material having a high corrosion resistance, excellent gloss, color tone, design and other aesthetic properties, and in particular, a deeply lacquered and highly artistically colored tone. Is provided.

内容とするものである。That is, the present invention is characterized in that a colored anodic oxide film layer, a pore-sealing layer and a polishing layer are sequentially formed on the surface of aluminum or an aluminum alloy, and the corrosion resistance and the beauty are improved. It is made of anodized building material with excellent properties.

An example of the colored anodic oxide film layer is bronze, stainless steel color or the like.

では、深みのある漆調の色彩効果が発現され難い。The sealing layer in the present invention is not particularly limited, and can be formed by an ordinary sealing treatment method. Since both the anodized film layer and the sealing treatment layer are opaque and have poor gloss and color tone, the surface of the sealing treatment layer is polished to form a transparent polishing layer. The polishing in the present invention is not particularly limited as long as the colored anodic oxide film layer and the sealing treatment layer are not removed or damaged. For example, buffing can be used if it takes sufficient time and is carefully polished, but it is unavoidable that the buffs have streaks. Therefore, lapping polishing is suitable for obtaining a perfect mirror-like gloss without such lines. For example, a water break polishing method in which a mixed liquid of water and a polishing material such as ferrite or alumina is applied to and impregnated in a fibrous material such as felt, and planar lapping is performed is preferable. Abrasive grain size 2
Those having a small size of not more than μm are preferable, and those having no corner are preferable. In addition, it is preferable that 250 to 300 g of the abrasive is mixed with 10 liters of water. The degree of polishing is preferably about 3 μm or less, and usually about 1 μm. The finished thickness of the anodized film layer, the pore-sealing layer and the polishing layer is preferably about 15 to 20 μm for the interior material and 20 μm or more for the exterior material. If it is less than 15 μm, it is difficult to develop a deep lacquer-like color effect.

て耐食性に優れている。In the alumite building material having the above-mentioned structure, the coloring layer is raised through the transparent polishing layer, so-called "color retention" occurs, and a deep lacquer-like color is exhibited. In addition, the anodized building material of the present invention does not have the anodic oxide film layer falling off and, of course, does not scrape off the sealing treatment layer, and therefore has excellent corrosion resistance.

る。As described above, the anodized building material of the present invention has many advantages and has excellent characteristics as a building material. To further improve durability, pinholes of aluminum or aluminum alloy ingots are required. In order to close the pinholes in the anodized film or the pinholes caused by excessive polishing, it is desirable to further subject the alumite building material to chromate treatment to form a chemical conversion film layer. An example of the composition of the chromate treatment bath and the treatment conditions is shown below. Chromate treatment bath composition: Dichromic acid 15 g / l Phosphoric acid 0.15 g / l (PH: Neutralize with caustic soda to about 6.8) Chromate treatment condition: Bath temperature approx. 40 ° C Dipping (non-electrolytic) approx. 1 min. The anodized building material with a chemical conversion film formed as shown in the figure has a further improved corrosion resistance and can retain its cosmetic properties for a longer period of time, so it can be placed in harsh environments such as wind and rain, dust, exhaust gas, and acid rain. It is particularly suitable as an exterior material to be peeled off.

を有し、その有用性は極めて大である。As described above, the alumite building material of the present invention has the following features: (1) The coloring layer in the pores floats up through the transparent polishing layer to become a so-called “accumulation color”, which is deep and deep in lacquer; Bring out interesting color effects. That is, it is possible to provide a stable and large amount of lacquer, which is a color tone unique to organic substances, with an inorganic substance such as aluminum (or an alloy thereof), and without requiring high technology and skill like lacquer. .. (2) The sealing treatment layer as well as the anodic oxide film layer does not fall off, so it has excellent corrosion resistance and light resistance. (3) When a lapping polishing layer is provided, no polishing marks remain and it is mirror-like and glossy. The gloss is much better. In addition, the surface is in the form of a glaze of ceramics and is in a state of being positively ceramicized and is extremely robust. (4) Since the anodized film layer itself is polished, even if the film layer itself is translucent, Only the surface layer can give gloss. (5) Since only the surface layer of the anodic oxide film layer needs to be polished, it can be easily re-polished at the construction site, which allows a semi-permanently beautiful appearance to be reproduced. Can be maintained. Therefore, it is very easy to maintain. (6) Corrosion resistance is further improved by closing the pinhole of aluminum ingot, the pinhole of anodic oxide film, or the pinhole by polishing with the chemical conversion film layer by chromate treatment. It has many advantages such as being suitable as an exterior material, and its usefulness is extremely large.
