JPH07185490A - Removal of oil contaminant - Google Patents

Abstract

PURPOSE:To provide an oil contaminant removing method capable of simply and certainly peel a protective film from an object to be protected after the adhesion of an oil contaminant by convering the object to be protected with the protective film excellent in releasability. CONSTITUTION:Paint 3a having releasability is applied to the surface of an object to be protected to which an oil contaminant is easily bonded and the formed paint layer is covered with a fiber sheet 4 before the paint is dried and paint 3b is again further applied to the sheet 4 to form a protective film 2 composed of the paint reinforced by the fiber sheet. After the adhesion of an oil contaminant, the protective film 2 is peeled from the object 1 to be protected.

Description

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 stains are likely to adhere to a ventilation fan and a hood covering an exhaust port of a kitchen, and the oil stains once solidified are hard to be removed, so that the removing work is very difficult. Therefore, conventionally, an antifouling sheet formed 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 target such as a ventilation fan or a hood, and the surface thereof is used. When a certain amount of oil stain is attached to the antifouling sheet, the antifouling sheet is peeled off from the antifouling object to remove the attached oil stain together with the antifouling sheet from the antifouling object.

However, the above conventional antifouling sheet is
Since the adhesive is applied to a synthetic resin film having a smooth surface, the adhesive is easily peeled off from the film, and when the antifouling sheet is peeled 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 coating having excellent releasability on an antifouling object so that the protective coating can be applied to the antifouling object after oil stains are attached. 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, the removal method of the present invention applies a peelable paint to the surface of an antifouling object to which oil stains easily adhere, and the paint does not dry. Forming a protective coating made of paint reinforced by the fiber sheet by covering the fiber sheet inside and applying the coating again from above, and peeling the protective coating from the antifouling target object after oil stains are attached. It is characterized by. Further, another method of the present invention is to protect the surface of an antifouling object to which oil stains are easily attached, by applying a paint having releasability in which reinforcing fibers are mixed to protect the surface with 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, since the paint and the fiber sheet or the fibers are integrated with each other, the strength is high, and the paint and the fiber sheet or the fibers are difficult to separate, and easily peeled from the antifouling object. A possible protective coating is formed. Therefore, when the protective coating with oil stains is peeled from the antifouling target, the coating remains or remains attached to the antifouling target,
There is no inconvenience that the paint separates from the fiber sheet or the fibers and falls around, and the protective coating can be peeled easily and surely.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The removal method of the present invention will be described in detail below with reference to the drawings. 1 and 2 show a first method of the present invention. In this method, an antifouling object 1 such as a ventilation fan of a kitchen or a hood that covers an exhaust port is liable to be adhered with oil stains.
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 of all, a paint 3 that has appropriate adhesiveness, heat resistance, and safety.
a is applied to the surface of the antifouling object 1 to a required thickness, and then
The fiber sheet 4 is coated on the coating material 3a before the coating material 3a dries, and the same coating material 3b is applied again on the coating material 3a to a required thickness, so that the coating material 3a, 3b is coated with the fiber sheet 4. . Thereby, on the surface of the antifouling target 1,
The protective coating 2 made of the paint reinforced by the fiber sheet 4 is formed.

As the above-mentioned paint, one having a larger adhesion to the fiber sheet 4 than 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 fibrous sheet 4 into the coating material having the adhesive force as described above, the coating material sufficiently penetrates into the fibrous sheet 4 to be integrated, and the strength is high, and the coating material and the fibrous sheet are large. 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
The fiber sheet 4 does not necessarily have to be applied thick enough to completely cover the fiber sheet 4, and may be applied to a thickness such that the fiber sheet 4 can sufficiently penetrate and form the desired protective coating 2.

Thus, when the antifouling object 1 on which the protective film 2 is formed is used for an appropriate 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 high strength, and the coating material is easily adhered to and integrated with the fiber sheet 4 and is not separated to be easily separated from the antifouling target 1. 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 coating material 13 in which a reinforcing short fiber 14 having an appropriate length is mixed is used, and the coating material 13 is applied to the surface of the antifouling object 1 to a required thickness to reinforce the fiber 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, a protective film having excellent releasability can be provided on an antifouling object and the protective film can be formed after oil stains are attached. It can be easily and surely peeled from the stainproof object.
