た。"Operation" The present inventors investigated the corrosion resistance of aluminum alloys having various compositions and structures in order to obtain better aluminum alloy powder for paints. As a result, it was found that an amorphous or a mixed phase alloy of amorphous and microcrystalline materials produced by rapidly cooling and solidifying a molten aluminum alloy having the above composition have excellent corrosion resistance. Additionally, since it is made by directly rapidly solidifying molten metal, it was found to have excellent surface gloss. As a result, it was found that by using an aluminum alloy powder having the above composition of amorphous or a mixed phase of amorphous and fine crystalline, a paint with superior corrosion resistance such as water resistance, weather resistance, and moisture resistance can be obtained.

の結果、十分な耐食性が得られなくなる。The composition of the aluminum alloy mentioned above is such that it is easy to form an amorphous phase by rapid solidification, and outside the above composition range, it becomes difficult to form an amorphous phase, and as a result, sufficient Corrosion resistance cannot be obtained.

ク現象が起こりにくくなる。In addition, as a result of various studies regarding the shape of the powder, including its thickness, aspect ratio, minor axis, and major axis, we found that while maintaining a good coating condition, we were able to effectively cause the leafing phenomenon and increase the corrosion resistance effect. It was found that it is necessary to keep it within the above range. That is, the thickness is 0.
If the thickness is less than 1 LLm, there is a problem in maintaining long-term corrosion resistance, and if the thickness exceeds 5 μm, the smoothness of the coating film will deteriorate. Further, if the short axis is 5 μm or less, the powders overlap each other non-uniformly, and if the long axis exceeds 500 μm, the strength of the coating film deteriorates. Furthermore, if the aspect ratio is less than 5, the leaf ink phenomenon is less likely to occur.

候性、耐湿性が得られる。Since the paint of the present invention contains the above-mentioned aluminum alloy powder, when it is applied, the surface to be coated is covered with the aluminum alloy powder due to the leafing phenomenon, and excellent water resistance, weather resistance, and moisture resistance can be obtained.

によれば、前述した形状特性を有するアルミニウム合金
粉末を７０％以上の収率で製造することができる。"Preferred Embodiment of the Invention" A preferred method for producing the aluminum alloy powder of the present invention is to flow out a molten aluminum alloy having the above-mentioned composition from a nozzle, and spray a gas onto the molten metal to generate droplets of the molten metal. Another method is to cause the droplets to collide with the surface of an umbrella-shaped or horn-shaped rotary cooling body disposed in the direction of the droplet flow, and to rapidly solidify the droplets before they solidify. Then, if necessary, a powder having the above-described shape characteristics may be fractionated from the obtained powder. According to this method, aluminum alloy powder having the shape characteristics described above can be produced at a yield of 70% or more.
本発明の塗料において、アルミニウム合金粉末は５〜２
０ ｖｏｌ％含有されていることが好ましい。In the paint of the present invention, the aluminum alloy powder contains 5 to 2
It is preferable that the content is 0 vol%.

工密着性が悪（なるため好ましくない。If the powder content is less than 5 vol%, there will be a large portion of only the base paint in the coating during coating, and the effect of powder mixing will not be achieved. Moreover, if it exceeds 20 vol%, the strength of the coating film becomes weak, cracks and peeling may occur, and processing adhesion becomes poor, which is not preferable.
