Description
Patented Oct. 17, 1933 1 UNITED STA raocsss FOR MAKING JAPANNED,
METALLIC TILES Sotojiro Asobc, Kanazawa-Shi, Japan No Drawing. Application June 18, 1931, Serial No. 545,377, and in Japan March 19, 1931 j 1 Claim.
The present invention'relates to a process for making japanned metallic tiles characterized in that .the epidermis or shell is made with metals 10 whereupon medium and/or final coating of japan may be applied and its object is to obtain elegant japanned metallic tiles especially fitted for dressing of concrete walls, the coated layer of which is stuck so firmly to the shell that even severe changes of temperature and moisture will never cause it to come off. v r
If, according to the present invention, shells of tiles made with metals or alloys, especially with aluminium, aluminium alloys, magnesium alloys or the like, by casting, pressing or, the like method are coated with the prepared mixture of red ochre, tonoko and kiurushi and then heated at 180-220 C. and finally finishing operation such as medium and/or upper coating is applied, are obtained japanned metallic tiles which are extremely durable, good for severe changes of temperature or moisture and the like, rustless, and most fit for dressing walls of concrete buildings. The fact thatsuch durable ground coating as mentioned above is obtainable is probably due to the congelatlng and adhering property of the sub-' stances formed from klurushi-by heating the latter at the comparatively. high temperature such as 180-220 Cain the presence of red ochre and the property of red ochre itself which promotes the adhering action ofthe above-said substances to the metallic surface of the tile-shell as well as the property of tonoko which facilitates the adhering action of the upper coating material. The baking operation must be operated at temperature between 180-220 C. If the tempera-' ture be lower than 180 C., the japan layer is liable to come off, while the temperature higher than 220 C. leads to failure. Upper layers to be coated successively thereon may be preferably baked. It is to be understood that the term raw japan or kiurushi, used herein applies to unpurified Japanese lacquer, which is secreted from the J apanese lacquer-tree (Rhus vernicifera) the principal constituent of which is japannic acid. A practical example of the process according to the present invention is given as follows: 5
A tray-shaped shell is casted with an aluminium alloy. On the outer surface the prepared mixture of 50% kiurushi, 25% red'ochre and 25% tonoko is coated and heated electrically at 200 C. for 18 minutes. The prepared mixture of 38% 7o tonoko, 24% kiurushi. and 38% water is then coated on the obtained ground and baked, the coating and baking operations being repeated twice. After polishing the surface, it is coated with japan and it is upon a finishing coating of japan is applied and it is polished in order to obtain the elegant lustre proper to japan. If the japanned aluminium alloy tile thus obtained is inlaid in the surface of concrete wall before complete setting of the latter, so for example, and then the concrete of the wall is caused to set completely, there is to be finished an elegantly dressed wall. In the recess or concavity of the back of the tile may be provided a frame or cross-piece which ensures insertion tion of the tile in concrete wall.
Iclaim:' The process for the production of japanned metallic tile, which consists in coating the'surface of the tile with a moist mixture of red ochre (oxide of iron), tonoko (levigatedfine powder of clay slate or fine powder of Japanese grinding stone) and kiurushi (raw japan) heating the coated tile to a temperature of 180-220 C. and then polishing the surface and applying thereto a coating of japan and polishing the same.
