ことができなかった。For this reason, the use of inorganic additives has been proposed in the past, but they have poor adhesion to the object to be coated, and it is not possible to form a thick coating film.
この発明の目的は、塗膜の不燃化および高耐久化を図り
、かつ厚い塗膜が得られる防食塗装構造を提供すること
である。An object of the present invention is to provide an anticorrosive coating structure that makes the coating film nonflammable, highly durable, and provides a thick coating film.
この発明の防食塗装構造は、被塗物の表面にを機塗１漠

Furthermore, high durability and nonflammability can be achieved by using an inorganic coating film.

脂などがあげられる。Examples of the inorganic coating include alkoxide inorganic coatings, and in particular, so-called silicone-modified varnishes that have an alkoxide group (such as a methoxy group) in the molecule and are modified with a Ja-containing resin to cure at low temperatures. A coating film consisting of the following can be suitably employed, and has excellent adhesion with organic coating films. Examples of the organic resin include alkyd resin, polyester, epoxy resin, acrylic resin, and urethane resin.
また、前記有機塗膜としては、通常のアルキド樹脂塗料

えで好ましい。FIG. 1 is a cross-sectional view showing an example of a heavy-duty anti-corrosion coating, in which an organic coating 2 is formed on the surface of an object to be coated such as metal, and then an inorganic coating 3 is applied thereon and cured to form a laminated layer. Then, by repeating this scraping process, the organic coating film 2 and the inorganic coating film 3 are alternately laminated to increase the thickness of the entire coating film and form a thick layer. Here, the number of laminated layers is not particularly limited, and in addition to the two layers of organic coating film 2 and R-free coating film 3, multiple layers may be alternately laminated, but the outermost layer of the coating film It is preferable to form the R-free coating film 3 in order to improve the durability and nonflammability of the coating film.
また、被塗物ｌ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。Furthermore, the object to be coated is not limited to metal only,
It is also applicable to slate, etc.
このようにして形成される塗膜は厚肉状で形成され、高

。Furthermore, since this coating film contains an inorganic coating film, it is also excellent in nonflammability, making it suitable for use in housing construction materials and the like.
次に実施例をあげてこの発明の防食塗装構造を説明する
。Next, the anticorrosion coating structure of the present invention will be explained with reference to Examples.

Further, the same alkyd resin paint and silicone modified varnish as above were sequentially applied to the upper surface to obtain a coated structure as shown in FIG. This coating has excellent durability and will not peel off easily even after long-term use.
It also had excellent nonflammability. Furthermore, it had far superior anti-corrosion performance compared to conventional organic coatings with a gore layer structure.
