Abstract

PROBLEM TO BE SOLVED: To improve durability against conditions such as weather, ultraviolet ray or the like by disposing an epoxy resin layer on the surface of a slate, and disposing a fluororesin layer on the surface of the epoxy resin layer to protect the surface of the slate. SOLUTION: Epoxy coating material is undercoated on the surface of a colored bestos 20 obtained by applying colored cement to the surface of a moisture absorbing slate to ensure water-proof to dispose an epoxy resin layer 31. Subsequently, fluorine-contained painting material is applied as final coating to the surface of the epoxy resin layer 31 to dispose a fluororesin layer 41. Subsequently as an intermediate coating, acrylic coating is applied between the epoxy resin layer 31 and the fluororesin layer 41 to heighten the adhesiveness of the fluororesin layer 41 to the colored bestos 20. Thus, the epoxy resin layer 31 is disposed on the surface of the roof slate 20, and further the fluororesin layer 41 is disposed to protect the surface of the colored bestos 20 so that the durability can be improved.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coating structure for a roof slate and a method for coating the same, and is used for a color vest or the like laid on a roof.

[0002]

2. Description of the Related Art A color vest (roof slate) laid on a roof is made by coating the surface of a hygroscopic slate with color cement to ensure waterproofness.

[0003] By the way, this color cement is used for
Since it is easily eroded by natural conditions such as ultraviolet rays, the erosion of these materials has conventionally been usually prevented by applying a urethane resin, an acrylic resin or a silicone resin.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to further improve the durability of a color vest against natural conditions such as wind, rain and ultraviolet rays.

[0005]

In order to achieve the above object, in the coating structure of a roof slate according to the present invention, an epoxy resin layer is provided on the surface of the roof slate and the epoxy resin layer is provided on the surface of the epoxy resin layer. Since the fluorine resin layer is provided, the surface of the roof slate is protected by the fluorine resin layer.

If an acrylic resin layer is interposed between the epoxy resin layer and the fluorine resin layer, the adhesion between the epoxy resin layer and the fluorine resin layer is improved.

In order to achieve the above object, in the coating structure of a roof slate according to the present invention, an epoxy resin layer is formed by applying an epoxy paint on the surface of the roof slate, and then the epoxy resin layer is provided. The surface of the roof slate is protected by a fluorine resin layer by applying a fluorine coating on the surface of the slate. In addition, after applying an epoxy paint to the surface of the roof slate and providing an epoxy resin layer, an allyl paint is applied to the surface of the epoxy resin tank to provide an allyl resin layer, and a fluorine paint is applied to the surface of the acrylic resin tank. Is applied to provide a fluorine resin layer, thereby improving the adhesion between the epoxy resin layer and the fluorine resin layer.

The above-mentioned overcoating, intermediate coating and undercoating can be performed by any conventional coating method.

FIG. 1 is a sectional view of a building, and FIG.
FIG. 3 is an enlarged view of part II, and FIG. 3 is a view of another embodiment corresponding to FIG.

In FIG. 1, 10 is a building and 11 is its roof. The roof portion 11 has a required number of color vests (roof slate) 20, 20,... Here, the color vest 20 is obtained by coating the surface of the hygroscopic slate with color cement to ensure waterproofness.

Referring to FIG. 2, the method of coating the color vest 20 and the structure of the coating film will be described.

First, an epoxy paint is applied as an undercoat on the surface of the color vest 20 to provide an epoxy resin layer 31.
In this case, the epoxy paint may be any commonly used one. It is preferable to use a two-pack reaction type epoxy paint to improve the adhesion to the color vest 20.

Next, a fluorine coating is applied as a top coat on the surface of the epoxy resin layer 31 to provide a fluororesin layer 41. In this case, the fluorine coating may be any commonly used one. Fluoro paints are better if they are one-part paints, and will not easily attack the coating on the color vest 20.

[0015] As the intermediate coating, the epoxy resin layer
If an acrylic paint is applied between 31 and the fluorine resin layer 41 and an acrylic resin layer 51 is interposed therebetween, the adhesion of the fluorine resin layer 41 to the color vest 20 is further improved.
In this case, the acrylic paint may be any commonly used one.

[0016]

According to the coating structure of the roof slate according to the present invention, the epoxy resin layer is provided on the surface of the roof slate and the fluorine resin layer is provided on the surface of the epoxy resin layer. As a result, the durability of the slate is improved.

If an acrylic resin layer is interposed between the epoxy resin layer and the fluorine resin layer, the adhesion between the epoxy resin layer and the fluorine resin layer is improved. The durability of the slate is improved.

Further, the coating structure of the roof slate according to the present invention is obtained by applying an epoxy resin to the surface of the roof slate to provide an epoxy resin layer, and then applying a fluorine coating to the surface of the epoxy resin. Since the fluorine resin layer is provided, the surface of the roof slate is protected by the fluorine resin layer, so that its durability is improved.

The surface of the roof slate is coated with an epoxy resin to provide an epoxy resin layer, and then the surface of the epoxy resin tank is coated with an allyl resin to provide an allyl resin layer. If a fluorine resin layer is provided by applying a fluorine coating to the epoxy resin layer, the adhesion between the epoxy resin layer and the fluorine resin layer is improved, and the durability of the roof slate is further improved.
