DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for removing oil stains adhering to a ventilation fan in a kitchen or a hood covering an exhaust port.

[0002]

2. Description of the Related Art Oil dirt easily adheres to a ventilation fan or a hood covering an exhaust port of a kitchen, and the oil dirt once adhered hardens and hardly falls off. For this reason, conventionally, an antifouling sheet obtained by applying an adhesive to the surface of a synthetic resin film is used, and the antifouling sheet is attached to the surface of an antifouling object such as a ventilation fan or a hood, and the surface thereof is When a certain amount of oil stain adheres to the antifouling sheet, the stainproof sheet is peeled off from the antifouling object to remove the adhered oil stain together with the antifouling sheet from the antifouling object.

However, the above conventional antifouling sheet is
Since the adhesive is applied to the synthetic resin film having a smooth surface, the adhesive is easily peeled off from the film, and when the antifouling sheet is peeled off from the antifouling target, the adhesive peeled off from the film. Since the agent remains attached to the surface of the antifouling target, it takes a lot of time to remove the remaining adhesive.

[0004]

The technical problem of the present invention is to provide a protective film having excellent releasability on an antifouling object, so that after the oil stain adheres, the protective film is applied to the antifouling object. Another object of the present invention is to provide a method for removing oil stains, which can be easily and surely peeled off.

[0005]

In order to solve the above-mentioned problems, a method of the present invention is to apply a releasable paint to the surface of an antifouling object to which oil stains easily adhere, and the paint does not dry. By coating the fiber sheet in the meantime and applying the paint again from above, forming a protective film of the paint reinforced with the fiber sheet, and peeling off the protective film from the antifouling object after the oil stain adheres. It is characterized by the following. Further, another method of the present invention is to apply a releasable paint mixed with reinforcing fibers to the surface of an antifouling object to which oil stains are liable to adhere, thereby providing protection by a fiber-reinforced paint. The invention is characterized in that a coating film is formed, and after the oil stain is attached, the protective coating is peeled off from the stainproof object.

[0006]

According to the above method, the paint is integrated with the fiber sheet or fiber, so that the strength is large, the paint and the fiber sheet or fiber are hardly separated, and easily peeled off from the antifouling object. A possible protective coating is formed. Therefore, when peeling off the protective coating to which the oil stain adheres from the antifouling object, the paint remains attached to the antifouling object,
There is no inconvenience that the paint separates from the fiber sheet or the fiber and falls to the surroundings, and the protective coating can be easily and reliably peeled off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The removal method of the present invention will be described in detail below with reference to the drawings. FIGS. 1 and 2 show a first method of the present invention. In this method, an antifouling object 1 to which oily dirt easily adheres, such as a kitchen ventilation fan or a hood covering an exhaust port.
Prior to its use or after cleaning, a protective coating 2 having a peeling property is formed on the surface of No. 1 by the following procedure. That is,
First, a paint 3 having moderate adhesiveness, heat resistance and safety
a is applied to the surface of the antifouling object 1 to a required thickness, and then
Before the paint 3a is not dried, the fiber sheet 4 is coated thereon, and the same paint 3b is applied again to a required thickness from above, whereby the fiber sheet 4 is applied to the paints 3a and 3b. . Thereby, on the surface of the antifouling target 1,
The protective coating 2 made of the paint reinforced with the fiber sheet 4 is formed.

As the paint, a paint having an adhesive force to the fiber sheet 4 larger than an adhesive force to the antifouling object 1 is used, and the fiber sheet 4 is made of a heat-resistant fiber material. Either a woven cloth or a non-woven cloth can be used, but when a woven cloth is used, a slightly coarse weave is preferable.

Thus, by coating the fiber sheet 4 into the paint having the above-mentioned adhesive force, the paint sufficiently penetrates and integrates into the fiber sheet 4 to have high strength, and the paint and the fiber sheet It is possible to form the protective coating 2 which is difficult to separate from the antifouling target 1 and which can be easily peeled off from the antifouling target 1. In this case, the paint is
It is not always necessary to apply the coating so thickly that the fiber sheet 4 is completely covered and hidden, but it is sufficient to apply the coating so as to sufficiently penetrate the fiber sheet 4 to form the desired protective coating 2.

When the antifouling object 1 on which the protective film 2 is formed is used for a suitable period of time and oil stains adhere to the surface of the protective film 2, as shown in FIG. The oil stain is removed together with the protective coating 2 by peeling from the protective film 2. At this time, the protective coating 2 is reinforced by the fiber sheet 4 and has a large strength. Further, the coating material is easily separated from the antifouling target object 1 without being firmly integrated with and separated from the fiber sheet 4. Therefore, the peeling work can be easily performed.

On the antifouling object 1 from which the oil stain has been removed by peeling off the protective film 2, the protective film 2 is formed again by the method described above.

FIG. 3 shows the second method of the present invention.
In this method, a paint 13 mixed with an appropriate length of reinforcing short fibers 14 is used, and the paint 13 is applied to the surface of the antifouling object 1 to a required thickness to thereby be reinforced with the fibers 14. The protective coating 12 is formed by the coating material 13 and the protective coating 12 is peeled off after the oil stain is attached. In this case as well, it goes without saying that the coating material 13 showing the required peeling property with respect to the antifouling object 1 is used.

[0013]

As described above in detail, according to the present invention, it is possible to provide a protective film excellent in releasability on an antifouling object, and to apply the protective film after adhesion of oil stains. It can be easily and surely peeled from the stainproof object.
