ことができる。As described above, according to the present invention, the organic coating film and the alkoxide inorganic coating film having excellent adhesion to each other are alternately laminated over a plurality of layers, so that both are firmly fixed and the entire coating film is formed in a thick-walled form. can do. Moreover, by using the alkoxide inorganic coating film, the coating film can be made incombustible.

タン樹脂などがあげられる。The alkoxide inorganic coating film has a alkoxide group (such as a methoxy group) in the molecule, and a coating film composed of a so-called silicone-modified varnish modified with an organic resin for curing at low temperature can be preferably adopted. Excellent adhesion to organic coatings. Examples of the organic resin include alkyd resin, polyester, epoxy resin, acrylic resin, urethane resin and the like.
また、前記有機塗膜としては、通常のアルキド樹脂塗
料、エポキシ樹脂塗料等から形成される有機防食塗膜が
あげられる。Examples of the organic coating film include organic anticorrosion coating films formed from ordinary alkyd resin paints, epoxy resin paints and the like.

えで好ましい。FIG. 1 is a cross-sectional view showing an example of a heavy anticorrosion coating film, in which an organic coating film 2 is formed on the surface of an article to be coated 1 such as a metal, and then an inorganic coating film 3 is coated and cured to form a laminate. Then, by repeating this operation, the organic coating film 2 and the inorganic coating film 3 are alternately laminated to increase the thickness of the entire coating film to form a thick wall. Here, the number of laminated layers is not particularly limited, and may be two layers of the organic coating film 2 and the inorganic coating film 3 or alternately laminated over a plurality of layers. The coating film 3 is preferable in order to enhance the durability and nonflammability of the coating film.
また、被塗物１は金属のみに限定されるものではなく、
スレートなどにも適用可能である。Further, the article to be coated 1 is not limited to only metal,
It is also applicable to slate and the like.
このようにして形成される塗膜は厚肉状で形成され、高

どに好適に使用しうるものである。The coating film formed in this manner is formed in a thick-walled form, has high anticorrosion performance, has excellent durability, and can be used for a long period of time. Furthermore, since this coating film contains an inorganic coating film, it is also excellent in non-combustibility and can be suitably used as a building material for houses.
次に実施例をあげてこの発明の防食塗装構造を説明す

していた。Example: An alkyd resin coating was applied on an iron plate and cured, and then a silicone-modified varnish was applied on the upper surface and cured. Further, the same alkyd resin paint and silicone-modified varnish as described above were sequentially applied to this upper surface to obtain a paint structure as shown in FIG. This coating film had excellent durability, did not easily peel off even after long-term use, and had excellent nonflammability. Further, it had a far superior anticorrosion performance as compared with the conventional organic coating having a multi-layer structure.
