[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The coating repair film of the present invention has a repair coating formed on a releasable substrate, and the repair coating contains a high boiling solvent.

[0007] The substrate is releasable. Releasable means that when a coating film is formed on a substrate, the coating film can be peeled from the substrate. Also,
It is possible to use a commercially available release agent to enable release.

[0008] Materials used for the substrate include:
For example, an acrylic resin plate, a polypropylene resin plate, or the like can be given. From the viewpoint of releasability, it is preferable to use a polypropylene resin plate.

The size and thickness of the substrate can be set arbitrarily. Considering the workability of handling, for example, as a size 30 × 30 ~ 100 × 100 cm,
Those having a thickness of 2 to 50 mm can be used.

The substrate preferably has substantially the same shape as the surface of the substrate of the coating film to be repaired, in order to reduce discomfort after repairing the cut surface of the coating film repair film. Substantially the same surface shape can be achieved by molding the substrate by molding the base material of the coating film to be repaired.

[0011] A repair coating film is formed on the coating film repair film of the present invention.

The repair coating is not particularly limited, and various types of coatings may be formed. The repair coating film may be a single layer, but when the repair target coating film has a multi-layer structure, it is preferably a coating film having a laminated structure adapted to this. In addition, the repair coating film may not have a design property, but a building material suitable for use of the paint film repair film of the present invention is often provided with a pattern. Preferably, there is. As such a pattern coating film, those applied to building materials can be used. Furthermore, it is preferable that the outermost layer of the repair coating film is a clear coating film layer. Here, when the repair coating is a single layer, the repair coating itself is a clear coating, but since the clear coating is rarely used alone, the outermost layer of the repair coating is a clear coating. In the case of a coating layer, the repair coating has a substantially multilayer structure. Here, the clear coating film includes a matting material, a material containing an aggregate, and a material colored to such an extent that the transparency is not hindered.

Specific examples of the repair coating film having a laminated structure, a patterned coating film, and a clear coating layer as the outermost layer thereof include, for example, a base coating film layer and a contrast with the base coating film layer. And a pattern coating layer, a clear coating layer or an aggregate-containing clear coating layer that can be recognized as a pattern.
When an aggregate-containing clear coating layer is formed as the clear coating layer, a pattern is formed using a colored aggregate or the like as the aggregate, and thus the pattern-forming coating layer may be omitted.

Particularly preferably, a base coat layer of a base coat paint is used, and then (1) a sponge transfer roll for transferring a pattern of a predetermined design is used, the residual viscosity at the time of coating is 0.1 to 5 Pas (25 ° C.), and the yield value is Is 5 to 30 Pa
(25 ° C.), the surface tension of the coating liquid is 25 to 45 dyn
/ Cm, or (2) a pattern coating layer formed of a coating containing a colored or non-colored aggregate having an average particle diameter of 0.1 to 1 mm and a resin, Then, the surface tension of the coating liquid is not larger than the surface tension of the dried coating film of the base coat paint and the pattern forming paint, and the clear film has a dry film thickness of 10 μm and an ultraviolet transmittance of 0 to 50% at a wavelength of 300 to 320 nm. This is a laminated coating film composed of a clear coating film layer made of a paint. Of course, the clear paint may contain an aggregate or a colored aggregate to improve the design.

The resin used for forming the repair coating film includes, for example, acrylic resin, polyester resin, silicone resin, acrylic silicone resin, acrylic urethane resin, fluorine resin, vinyl acetate resin, epoxy resin, etc. And water-based paints such as solvent-based paints and emulsion-type paints. Acrylic resin,
Those formed from paints using polyester resin, silicone resin, acrylic silicone resin, acrylic urethane resin and fluorine resin are preferable, and those formed from aqueous paints such as emulsion type are preferable from the viewpoint of environmental protection.

The repair coating contains a high-boiling solvent. For this reason, the flexibility of the repair coating film is developed, and the repair film can be applied even if the repair portion has irregularities or curved portions. In the present invention, a plasticizer that is not recognized as a solvent is also included in the high boiling point solvent.

The high boiling point solvent is preferably an organic solvent having a boiling point of 150 to 300 ° C. When the boiling point is lower than 150 ° C., the solvent volatilizes quickly, causing a problem in the workability of the application.
When the boiling point exceeds 300 ° C., the solvent does not evaporate even after a lapse of time, and the hardness of the repaired portion does not increase. A more preferred boiling point is 170 to 270 ° C. Boiling point 150-300 ° C
Specific examples of the organic solvent having a boiling point of benzyl alcohol (boiling point: 205 ° C), n-hexyl alcohol (boiling point: 157 ° C), 2-ethylhexyl alcohol (boiling point: 185 ° C), isophorone (boiling point: 215 ° C) ),
Furfuryl alcohol (boiling point: 168 ° C), dichloroethyl ether (boiling point: 179 ° C), diacetone alcohol (boiling point: 169 ° C), cyclohexanol (boiling point: 1
61 ° C), cyclohexyl acetate (boiling point: 177 ° C), 2-ethylbutyl acetate (boiling point: 162 ° C), ethyl lactate (boiling point: 154 ° C), butyl lactate (boiling point: 188 ° C), butyl butyrate (boiling point: 166
° C), oxalic acid ethyl ester (boiling point: 185 ° C), benzoic acid ethyl ester (boiling point: 199 ° C), ethylene glycol monobutyl ether (boiling point: 171 ° C), ethylene glycol monobenzyl ether (boiling point: 256 ° C),
Diethylene glycol monobutyl ether acetate (boiling point: 247 ° C), diethylene glycol monoethyl ether (boiling point: 203 ° C), diethylene glycol monomethyl ether (boiling point: 194 ° C), diethylene glycol diethyl ether (boiling point: 188 ° C), diethylene glycol dibutyl ether (boiling point: 231 ° C) ), Diethylene glycol monomethyl ether (boiling point: 194
° C), diethylene glycol monoethyl ether acetate (boiling point: 217 ° C), decalin (boiling point: 199
° C), turpentine (boiling point: 155 ° C), 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate (boiling point: 258 ° C) and the like. These can be selected according to the resin component constituting the repair coating film. However, from the viewpoint of imparting flexibility, ethylene glycol monobutyl ether, 2,2,4-trimethyl-1,3-pentanediol monoamine is used. Preferably, it is isobutyrate.

The high-boiling solvent may be contained in the paint in advance. In this case, the content of the high-boiling solvent is preferably 1 to 20 parts by weight based on 100 parts by weight of the paint. preferable. If the amount is less than 1 part by weight, the flexibility of the repair coating film becomes insufficient, and it becomes difficult to apply the film to irregularities and curved portions. On the other hand, when the amount exceeds 20 parts by weight, the repair coating film may swell excessively and deviate from the hardness suitable for repair.

The coating repair film of the present invention can be produced by forming a repair coating on a mold-releasable substrate and allowing the high-boiling solvent to penetrate the repair coating.
The releasable substrate is the same as that described in the description of the coating film repair film.

The repair coating film formed on the releasable substrate is not particularly limited, and the same applies to those described in the description of the coating film repair film. Further, the repair coating film preferably has the same structure as the repair target coating film. In other words, the coating is preferably the same as the coating to be repaired. This not only eliminates the discomfort between the repaired part and the non-repaired part,
This is because the production of the coating film repair film of the present invention is facilitated. That is, when applying the coating film repair film of the present invention to a building material having a laminated coating film provided with a pattern by line painting in a factory or the like, a substrate that can be released from the building material in a vacant space during line painting. By arranging and performing line coating, the desired coating film repair film can be easily obtained.

The penetration of the high-boiling solvent into the thus-obtained repair-coated film formed on the releasable substrate can be achieved by applying the high-boiling solvent to the surface of the repair coating film. It can be carried out. The high boiling solvent used here is the same as that described in the description of the coating film repair film.

When the above-mentioned high boiling solvent is applied to the surface of the repair coating film, spray application, roller application, brush application, etc. are possible, but spray application is preferred from the viewpoint of workability. The coating amount is preferably from 20 to 200 g / m ^2, is less than 20 g / m ^2, there is a risk of insufficient flexibility of the coating film repair film, repair coatings and exceeding 200 g / m ² is excessively swell , It may deviate from the hardness suitable for repair. More preferably, it is 50 to 100 g / m ² . Since the high boiling point solvent gradually penetrates into the repair coating film, after application, for example, it is allowed to stand at room temperature for 1 to 24 hours, and after sufficient penetration, it can be used for repair. preferable.

According to the method for repairing a coating film of the present invention, a coating film repair film having a repair coating film containing a high-boiling solvent is formed on a releaseable substrate, and the repair coating film is repaired. What cut | disconnected to the size according to the repair part of a coating film is stuck on the said repair part where the patch was applied, and is characterized by the above-mentioned.

The coating film to be subjected to the coating film repair method of the present invention is not particularly limited, but is preferably a laminated coating film on which a building material or the like is line-painted at a factory or the like and a pattern is provided. As the above-mentioned building material, various materials can be mentioned, and a ceramic building material which has been subjected to uneven processing may be used. As the ceramic building material subjected to the unevenness processing, for example, a ceramic building material used for the inner and outer walls of a house, asbestos slate board, wood chip cement board, calcium silicate board, magnesium carbonate board, slag gypsum board, lightweight foam concrete board and Panels using them can be given. The unevenness processing is performed by embossing, groove processing, or the like.

As the coating repair film prepared above, those already described above can be used. However, in order to eliminate a sense of discomfort between the repaired portion and the non-repaired portion, the repaired film has a design similar to the repair target coating film. The coating film repair film obtained by the same coating process as the coating film to be repaired is particularly preferable.

In the coating film repair method of the present invention,
The repair coating film is cut into a size corresponding to the repair location of the repair target coating film. The cutting is preferably performed so as to have an arbitrary irregular shape with few straight lines. If there are many straight lines in the cut portion, the boundary line of the repaired portion may be apparent, and the repairability may be reduced. Since the coating film repair film has flexibility, it can be easily cut into any arbitrary shape having few straight lines. In addition, this cutting work is usually performed after the repair coating is peeled off from the substrate. However, the material of the substrate is soft, and the repair coating and the substrate are cut off at the same time. May be peeled off from the substrate.

Next, the repaired coating film cut in this manner is attached to a repaired portion. If necessary, the repaired portion is subjected to a ground treatment such as roughening with sandpaper or the like, and a patch is applied somewhat widely. The patch is not particularly limited as long as it has adhesiveness, but it is preferable to use the paint or resin used for forming the outermost layer of the repair coating film. The application of the patch can be performed by an application method suitable for the repair area, for example, spray application, roller application, or brush.

Attachment of the repair coating film to the repaired portion is performed by pressing the cut repair coating film over the patch in a state where the patch has fluidity. Because the repair coating used in the coating repair method of the present invention has flexibility, even if there is unevenness or a curved portion in the repaired portion,
It can be easily attached.

At this time, when the pores are opened in the repair coating film, the patch spreads to the surface or the boundary through the pores. Thereby, the repaired portion and the non-repaired portion are easily integrated, and the repairability is improved. The pores may be of a size that allows the patch to diffuse, but the diameter is preferably 3 mm or less so as not to impair the appearance of the coating film. Further, it is preferable that a plurality of the pores are provided for the repair coating film. The arrangement is arbitrary, but from the viewpoint of improvement in repairability, substantially the same interval is preferable.

The above-mentioned pores can be opened from the front surface or the back surface so as to penetrate the repair coating using, for example, a pointed tool such as a needle or a pin. The work of opening the pores can be performed at any stage before and after the application. As a method of opening the above-mentioned pores at a stage before sticking, by opening a hole large enough to not be coated with the repair coating on the releasable substrate, and also to apply the repair coating on the releasable substrate By forming the releasable needle-like projections longer than the film thickness, pores can be opened in the repair coating film when the repair coating film is released.

After the application, the device is left at room temperature for 1 to 7 days to complete the repair. At the beginning of application, the hardness of the repair coating is different from the hardness of the non-repaired portion, but the high boiling point solvent in the coating repair film volatilizes over time, and is substantially the same as the coating hardness of the non-repaired portion. And there is no difference in appearance.
