Description

  The present invention relates to a coating transfer film used for partial coating of a surface of, for example, a vehicle body and a coating method using the coating transfer film.

  For example, when a body of an automobile or the like is repaired or simply repaired, partial coating is performed on the surface of the sheet metal or the repaired body. Conventionally, this partial coating has been performed by spraying a paint from a spray gun or an aerosol spray on a necessary part and its periphery.

  However, in order to finish the painted surface beautifully by spraying like this, considerable training and some experience are required, and painting should be performed so that those who are inexperienced and those who are not painting experience a beautiful appearance Was very difficult.

  A transfer film for transferring a three-dimensional pattern portion to the back side of a resin part such as an emblem of a vehicle is known, although it is not for coating after sheet metal repair or simple repair (Patent Document 1). In the transfer film described in Patent Document 1, a flat metal vapor deposition surface portion and a vertical wall coating surface portion are provided on a base film, and after this is provided inside a mold, a resin is injected into the mold. It is to be molded.

  Moreover, although it is not a transfer film, the dry paint film for coating on the vehicle body components comprised from a polymer material is proposed (patent document 2). In the dry paint film described in Patent Document 2, a first colored paint layer is applied on a support material (base film) by knife coating, rolling, pouring or printing, and then a second colored paint layer is sprayed thereon. Is formed, and a transparent top layer is applied thereon. This dry paint film does not transfer the paint layer, but completes the coating as it is by adhering the base film together with the parts to be painted.

  As mentioned above, painting after sheet metal repair and simple repair requires considerable skill, and it is very difficult for inexperienced people and general users to finish the painted surface cleanly, and the partially painted part It was also very difficult to finish so that the boundary between it and its surroundings was unknown.

  Moreover, since the transfer film described in Patent Document 1 does not transfer the paint layer on the base film, it cannot be used for partial coating after sheet metal repair or simple repair.

  Furthermore, the dry paint film described in Patent Document 2 is difficult to use for partial coating after sheet metal repair or simple repair because of its configuration in which the base film adheres together, and the partial coating portion and its surroundings Since it is almost impossible to finish without knowing the boundary, it cannot be used.

  Accordingly, it is an object of the present invention to provide a transfer film for coating and a coating which can be easily applied to a certain level or more even when a person who has no painting experience or a person with little painting experience performs sheet metal repair or simple repair. Another object of the present invention is to provide a coating method using a transfer film.

  Another object of the present invention is to make sure that the boundary between the part-painted part and the surrounding area is not understood even when a person who has no painting experience or a person with little painting experience performs partial metallurgy repair or simple repair. An object of the present invention is to provide a coating transfer film that can be finished and a coating method using the coating transfer film.

  According to the present invention, a base film, a first clear paint layer laminated on the base film and soluble in a predetermined solvent, a multi-layer structure laminated on the first clear paint layer, and And a second clear paint layer laminated on the color paint layer and soluble in a predetermined solvent, the color paint layer having a center corresponding to the required paint area A coating transfer film is provided in which the portion is composed of the largest number of layers, and the peripheral portion of the central portion constitutes a color blurring portion having a smaller number of layers.

  Since the first clear paint layer, the color paint layer and the second clear paint layer on the base film are dissolved with a solvent and can be transferred to the surface of the object to be coated, there is no experience in painting. Even if a person performs painting after sheet metal repair or simple repair, painting at a certain level or more can be easily performed. In addition, the color paint layer is composed of the largest number of layers in the center corresponding to the required area, and the peripheral part of the center constitutes a color blurring part with a smaller number of layers. Thus, it is possible to finish so that the boundary between the partially painted portion and the periphery thereof is not known.

  It is preferable that the color blur portion is configured so that the number of layers gradually decreases in the outward direction.

  It is also preferable that the second clear coating layer has a maximum film thickness at the center and a clear blur part having a thinner film thickness at the periphery of the center.

  The first clear paint layer has a maximum film thickness at the central portion, and the peripheral portion of the central portion constitutes a clear blurring portion having a thinner film thickness, or the central portion and its peripheral portion. Preferably have the same thin film thickness.

  It is preferable that the first clear paint layer and the second clear paint layer are formed of a one-component paint material and / or the color paint layer is formed of a two-component paint material.

  According to the present invention, a predetermined solvent is further applied to the surface of the object to be coated, and the above-mentioned coating transfer film is deposited on the applied solvent from the second clear paint layer side, A coating method using a transfer film for coating that peels off the base film after being rolled on a film and dried is provided.

  A part of the second clear paint layer is dissolved by the solvent applied to the surface of the object to be painted, and the second clear paint layer, the color paint layer and the first clear paint layer are transferred, and then applied to a roller. After expelling some of the mixed solvent and air bubbles and drying, the base film is peeled off. Since there is no painting process, even if a person who has no painting experience performs painting after sheet metal repair or simple repair, painting at a certain level or more can be easily performed only by performing a simple transfer operation. In addition, the color paint layer is composed of the largest number of layers in the center corresponding to the required area, and the peripheral part of the center constitutes a color blurring part with a smaller number of layers. Thus, it is possible to finish so that the boundary between the partially painted portion and the periphery thereof is not known.

  After applying the surface of the object to be painted, it is preferable to apply a predetermined solvent to the surface.

  It is also preferable to use a mixed solvent of a solvent and a degreasing agent as the predetermined solvent.

  After the base film is peeled off, it is also preferable to perform polishing using a compound on the first clear paint layer.

  It is also preferable to apply an additional clear coating layer on the first clear coating layer after the base film is peeled off.

  According to the present invention, even if a person who has no painting experience performs painting after sheet metal repair or simple repair, it is possible to easily perform painting at a certain level or more, and the partial painting portion and its surroundings. You can finish so that you don't know the boundaries.

  FIG. 1 is a cross-sectional view schematically showing a configuration of a coating transfer film as one embodiment of the present invention. However, in the figure, the thickness and size of each layer are exaggerated for easy understanding.

The coating transfer film of the present embodiment is a transfer film for applying a partial coating to the repaired portion after performing sheet metal repair or simple repair to flatten the surface of the dent of an automobile body and performing surface treatment. For example, a large number of transfer films having different paint colors and sizes are prepared in advance, and an appropriate one is selected and used according to the color and size of the required paint portion of the vehicle body. In the case of a car body, a color corresponding to the car body color and a size cut into, for example, A3 size, A4 size, B2 size, etc. are prepared. The maximum size that can be partially painted is about 3 dm ² (300 cm ² ).

  As shown in FIG. 1, a coating transfer film (first type transfer film) 10 of this embodiment is a thinner (a general lacquer thinner such as Kansai Paint Co., Ltd.) that is a solvent such as a polyethylene film. A base film 11 that is a flexible resin film that does not dissolve in Selva 51), and an automotive clear (for example, manufactured by Kansai Paint Co., Ltd.) that is one-component and dissolves with thinner after curing on the base film 11. The first clear paint layer 12 laminated by applying a transparent paint which is Aclick 1000), and has a desired color on the first clear paint layer 12 and is two-component and cured. After that, a coating that does not dissolve (for example, PG2K from Kansai Paint Co., Ltd.) is applied multiple times (in this example, 4 times) to apply multiple layers. A transparent color coating layer 13 and a clear for automobiles (for example, Click 1000 from Kansai Paint Co., Ltd.) that is one-component on the color coating layer 13 and dissolves with thinner after curing. And a second clear paint layer 14 laminated by applying a paint. The paint of the color paint layer 13 is preferably two-part paint, but one-part paint (for example, PG Hybrid Eco manufactured by Kansai Paint Co., Ltd.) can also be used.

  The color paint layer 13 has a four-layer structure in which a first layer 13a, a second layer 13b, a third layer 13c, and a fourth layer 13d are laminated in this order from the base film side. The first layer 13a is formed only at the center corresponding to the region requiring coating, the second layer 13b is formed wider than the first layer 13a, and the third layer 13c is formed around the second layer 13b. The fourth layer 13d is formed more widely around the periphery than the third layer 13c. Accordingly, the central portion corresponding to the region requiring coating is configured with the maximum number of layers, and the peripheral portion of the central portion forms a color blurring portion where the number of layers gradually decreases in the outward direction.

  In the present embodiment, the first clear paint layer 12 has a single-layer structure, the central part thereof has the maximum film thickness, and the peripheral part of the central part has a film thickness outward. It forms a clear blur that gradually decreases. The clear blur portion is formed by applying a thinned clear paint with a thinner.

  The second clear paint layer 14 also has a single-layer structure in this embodiment, the central portion thereof has the maximum film thickness, and the peripheral portion of the central portion has a film thickness outward. It forms a clear blur that gradually decreases. The clear blur portion is formed by applying a thinned clear paint with a thinner.

  The film thicknesses of the base film and each paint layer are merely examples in the present embodiment, but the base film 11 is about 20 to 60 μm, preferably about 30 μm, and the first clear paint layer 12 is about 20 to 20 μm. 25 μm, the color paint layer 13 is about 50-60 μm, and the second clear paint layer 14 is about 20-25 μm.

  In the present embodiment, the first clear coating layer 12 and the second clear coating layer 14 have a single layer structure, but these may have a multilayer structure. In this case, the clear blur part is configured to gradually reduce the film thickness by gradually decreasing the number of layers toward the outer side in the peripheral part of the central part.

  In the present embodiment, the first layer 13a, the second layer 13b, the third layer 13c, and the fourth layer 13d of the color coating layer 13 are arranged in this order, that is, from the side closer to the base film 11 toward the far side. The color blurring portion is formed so that the area gradually increases, but in this order, that is, the color blurring portion is formed so that the area gradually decreases from the side closer to the base film 11 toward the far side. It is clear that it is also good.

  FIG. 2 is a flowchart for explaining a processing procedure in the case of performing partial coating of a vehicle body repaired by sheet metal using the coating transfer film of the present embodiment, and FIG. 3 is a cross-sectional view showing a state of a coating portion in the processing procedure. FIG. 4 is a sectional view showing the state of FIG. 3 (F) in more detail.

  First, sheet metal processing using a putty or the like is performed on the recessed portion of the vehicle body to finish the surface flat (step S1). Next, this surface is subjected to a primer coating with Plasaf (primer surfacer) (step S2). FIG. 3A shows this state. In this figure, 30 is a steel plate of a vehicle body, 31 is an old coating film, 32 is a recessed portion, 33 is a putty filled in the recessed portion 32, and 34 is undercoated. Each shows Prasaf.

  Next, a footing process is performed on the transfer film sticking surface (step S3). In this footing process, the surface is polished with a footing compound or sandpaper of No. 2000, so that fine scratches are put on the surface of the plastic plate 34 and the surface of the old paint film 31 to improve the adhesion of the paint film. It is a process to make. FIG. 3 (B) shows the state after this footing process is performed, and it can be seen that fine scratches 35 are present on the surface of the plastic plate 34 and the old coating film 31.

  Next, degreasing treatment of the pasting surface is performed using a degreasing agent such as silicon off (step S4).

  Then, the process which apply | coats a mixed solvent to a sticking surface is performed (step S5). This mixed solvent was prepared by mixing thinner, which is a solvent capable of dissolving the paint layer on the transfer film, and silicon-off, which is a solvent used for adjusting the solvent evaporation rate, at a ratio suitable for dissolving the paint. It is a solvent. This mixed solvent is put into a spray gun or a sprayer, and sprayed over a wider range than the attachment surface of the vehicle body. In this case, the spray coating amount is until the mixed solvent is dripped. FIG. 3C shows a state where the mixed solvent layer 36 is applied in this manner.

  Next, the transfer film (first type transfer film) 10 of this embodiment is placed on the mixed solvent layer 36 so that the second clear paint layer 14 is in close contact with the mixed solvent layer 36, and thus the base film. 11 is attached so as to be on the top (step S6). At that time, pasting is performed so that the center of the undercoat (prasaf) coincides with the central portion of the color paint layer of the transfer film 10 that can be transferred. FIG. 3D shows a state where the transfer film 10 is attached.

  As can be seen from the figure, bubbles 37 inevitably enter between the mixed solvent layer 36 and the transfer film 10. Therefore, as the next step, a sponge roller is pressed from above the base film 11 of the transfer film 10, and an air bleeding process is performed by roller application (step S7). By this roller application, the bubbles 37 are pushed out and unnecessary mixed solvent is also pushed out. Further, the remaining small amount of the mixed solvent dissolves the surface of the second clear paint layer 14 of the transfer film 10, so that the portion expands and enters the scratch 35 due to the addition of the prassuff 34 and the old coating film 31. . For this reason, the adhesion between the transfer film 10 and the plastic film 34 and the old coating film 31 is greatly increased. FIG. 3E shows a state after the roller is applied.

  Next, the transfer film 10 is left to dry for an appropriate time (for example, 15 minutes) in a state where a part of the periphery of the transfer film 10 is taped with a masking tape or the like (step S8).

  Subsequently, the process which peels the base film 11 from the transfer film 10 is performed (step S9). This peeling process is performed by grasping and peeling off the edge of the base film 11, thereby completing the transfer process. FIGS. 3 (F) and 4 show this state after the transfer process is completed. The second clear paint layer 14 and the color paint layer remaining after the base film 11 is peeled off on the area of the vehicle body to be partially painted. 13 and the first clear paint layer 12 are laminated in this order from the vehicle body side (lower side).

  Thereafter, a polishing process using a polisher and a compound is performed (step S10). By this polishing process, as shown in FIG. 4, the scratches 35 caused by the foot remaining on the old coating film 31 are smoothed, and the rough portion of the edge 12a of the first clear paint layer 12 is also removed. Smooth.

  As described above, according to the present embodiment, the transfer film 10 is affixed on the mixed solvent layer 36 applied to the surface of the vehicle body to be coated, so that the mixed clear solvent 14 After the second clear paint layer 14, the color paint layer 13 and the first clear paint layer 12 are transferred to the surface of the object, the part is mixed with a roller to drive out part of the mixed solvent and bubbles, and then dried. After having been made, the base film is peeled off. Since there is no painting process, even a person who has no painting experience can easily perform a certain level of painting by simply performing a simple transfer operation. Even in a repair shop that does not perform sheet metal painting, repair painting can be performed simply by performing light repair and transfer work. In addition, the color coating layer 13 is configured with the maximum number of layers in the central portion corresponding to the required area, and the peripheral portion of the central portion forms a color blurring portion in which the number of layers gradually decreases outward. In addition, the first clear coating layer 12 and the second clear coating layer 14 also have the maximum film thickness at the center, and the film thickness at the periphery of the center is directed outward. Since the clear blurring portion that gradually decreases is formed, it is possible to simply finish the transfer so that the boundary between the partially painted portion and its periphery is not known. Furthermore, since only the transfer operation is performed without applying a paint, the generation of volatile organic substances is reduced, which is significant for environmental problems.

  FIG. 5 is a cross-sectional view schematically showing a configuration of a coating transfer film as another embodiment of the present invention. However, in the same figure, the thickness and size of each layer are exaggerated for easy understanding.

  The configuration and operational effects of this embodiment are that the first clear coating layer uses a second type transfer film in which the first clear coating layer is thin and has a uniform film thickness. Therefore, an additional clear coating layer is added after transfer. It is the same as that of the embodiment of FIGS. 1-4 except the point which needs to apply | coat.

The coating transfer film of the present embodiment is a transfer film for applying a partial coating to the repaired portion after performing sheet metal repair or simple repair to flatten the surface of the dent of an automobile body and performing surface treatment. For example, a large number of transfer films having different paint colors and sizes are prepared in advance, and an appropriate one is selected and used according to the color and size of the required paint portion of the vehicle body. In the case of a car body, a color corresponding to the car body color and a size cut into, for example, A3 size, A4 size, B2 size, etc. are prepared. The maximum size that can be partially painted is about 3 dm ² (300 cm ² ).

  As shown in FIG. 5, the coating transfer film (second type transfer film) 50 of this embodiment is a thinner (a general lacquer thinner such as Kansai Paint Co., Ltd.) that is a solvent such as a polyethylene film. A base film 51 that is a flexible resin film that does not dissolve in Selva 51), and an automotive clear (for example, manufactured by Kansai Paint Co., Ltd.) that is one-component and dissolves with thinner after curing on the base film 51. The first clear paint layer 52 laminated by applying a transparent paint which is Aclick 1000), and has a desired color on the first clear paint layer 52 and is two-component and cured. After that, a coating that does not dissolve (for example, PG2K from Kansai Paint Co., Ltd.) is applied multiple times (in this example, 4 times) to apply multiple layers. A transparent color coating layer 53 and a clear for automobiles (for example, Click 1000 from Kansai Paint Co., Ltd.) that is one-component on the color coating layer 53 and dissolves with thinner after curing. And a second clear paint layer 54 laminated by applying a paint. The paint of the color paint layer 13 is preferably two-part paint, but one-part paint (for example, PG Hybrid Eco manufactured by Kansai Paint Co., Ltd.) can also be used.

  The color paint layer 53 has a four-layer structure in which a first layer 53a, a second layer 53b, a third layer 53c, and a fourth layer 53d are laminated in this order from the base film side. The first layer 53a is formed only at the center corresponding to the region requiring coating, the second layer 53b is formed wider than the first layer 53a, and the third layer 53c is formed around the second layer 53b. The fourth layer 53d is formed more widely around the periphery than the third layer 53c. Accordingly, the central portion corresponding to the region requiring coating is configured with the maximum number of layers, and the peripheral portion of the central portion forms a color blurring portion where the number of layers gradually decreases in the outward direction.

  In the present embodiment, the first clear paint layer 52 has a single-layer structure with a thin and uniform film thickness.

  In the present embodiment, the second clear paint layer 54 has a single-layer structure, the central part thereof has the maximum film thickness, and the peripheral part of the central part has a film thickness outward. It forms a clear blur that gradually decreases. The clear blur portion is formed by applying a thinned clear paint with a thinner.

  The film thickness of the base film and each paint layer is merely an example in this embodiment, but the base film 51 is about 20 to 60 μm, preferably about 30 μm, and the first clear paint layer 52 is about 10 to 10 μm. 20 μm, the color paint layer 53 is about 50-60 μm, and the second clear paint layer 54 is about 20-25 μm.

  In the present embodiment, the second clear paint layer 54 has a single layer structure, but it may have a multilayer structure. In this case, the clear blur part is configured to gradually reduce the film thickness by gradually decreasing the number of layers toward the outer side in the peripheral part of the central part.

  Further, in the present embodiment, the first layer 53a, the second layer 53b, the third layer 53c, and the fourth layer 53d of the color coating layer 53 are sequentially increased in area in this order from the side close to the base film 51. Although the color blurring portion is formed, it is obvious that the color blurring portion may be formed so that the area gradually decreases in this order from the side closer to the base film 51.

  FIG. 6 is a flowchart for explaining a processing procedure in the case of performing partial coating of a vehicle body repaired by sheet metal using the coating transfer film of this embodiment. However, the following description will be made with reference to FIG. 3 used in the previous embodiment.

  First, sheet metal processing using a putty or the like is performed on the recessed portion of the vehicle body to finish the surface flat (step S11). Next, the surface is primed with a plasaf (primer surfacer) (step S12). FIG. 3A shows this state. In this figure, 30 is a steel plate of a vehicle body, 31 is an old coating film, 32 is a recessed portion, 33 is a putty filled in the recessed portion 32, and 34 is undercoated. Each shows Prasaf.

  Next, a footing process is performed on the transfer film sticking surface (step S13). In this footing process, the surface is polished with a footing compound or sandpaper of about 2000, so that fine scratches are put on the surface of the plastic plate 34 and the surface of the old paint film 31 to improve the adhesion of the paint film. It is a process to make. FIG. 3 (B) shows the state after this footing process is performed, and it can be seen that fine scratches 35 are present on the surface of the plastic plate 34 and the old coating film 31.

  Next, a degreasing process is performed on the affixed surface using a degreasing agent such as silicon off (step S14).

  Then, the process which apply | coats a mixed solvent to a sticking surface is performed (step S15). This mixed solvent is a solvent in which thinner, which is a solvent capable of dissolving the paint layer on the transfer film, and silicon-off, which is a degreasing agent for adjusting the solvent evaporation rate, are mixed at a ratio suitable for dissolving the paint. It is. This mixed solvent is put into a spray gun or a sprayer, and sprayed over a wider range than the attachment surface of the vehicle body. In this case, the spray coating amount is until the mixed solvent is dripped. FIG. 3C shows a state where the mixed solvent layer 36 is applied in this manner.

  Next, the transfer film (second type transfer film) 50 of this embodiment is placed on the mixed solvent layer 36 so that the second clear paint layer 54 is in close contact with the mixed solvent layer 36, and thus the base film. Affix 51 so as to be on (step S16). At that time, the pasting is performed so that the center of the coating portion coincides with the central portion of the transfer film 50. FIG. 3D shows a state where the transfer film 50 is attached.

  As can be seen from the figure, bubbles 37 inevitably enter between the mixed solvent layer 36 and the transfer film 50. Therefore, as the next step, a sponge roller is pressed from above the base film 51 of the transfer film 50, and an air bleeding process is performed by roller application (step S17). By this roller application, the bubbles 37 are pushed out and unnecessary mixed solvent is also pushed out. Furthermore, the remaining small amount of the mixed solvent dissolves the surface of the second clear paint layer 54 of the transfer film 50, so that the portion expands and enters the scratch 35 due to the addition of the prassuff 34 and the old paint film 31. . For this reason, the adhesion between the transfer film 50, the plastic plate 34, and the old coating film 31 is significantly increased. FIG. 3E shows a state after the roller is applied.

  Next, in order to prevent the transfer film 50 from being rounded, it is left to dry for a suitable time (for example, 15 minutes) with a part of its periphery taped with a masking tape or the like (step S18).

  Subsequently, the process which peels the base film 51 from the transfer film 50 is performed (step S19). This peeling process is performed by grasping and peeling off the edge of the base film 51, thereby completing the transfer process. FIG. 3 (F) shows this state after the transfer process is completed. The second clear paint layer 54, the color paint layer 53, and the second paint layer 54 remaining after the base film 51 is peeled off on the region to be partially painted on the vehicle body. One clear paint layer 52 is laminated in this order from the vehicle body side (lower side).

  Thereafter, a process of applying an additional clear paint layer is performed (step S20). This treatment is performed by spraying a transparent paint, which is a clear for automobiles (for example, Retan PG Multi-HX (Q) manufactured by Kansai Paint Co., Ltd.) onto the partial coating region and its periphery with a spray gun or the like. Note that lettan PG multi-HX (Q) is a two-component urethane paint, and by using this, weather resistance is improved and glossiness hardly occurs, so a state close to full-scale coating can be obtained.

  As described above, according to the present embodiment, the transfer film 50 is stuck on the mixed solvent layer 36 applied to the surface of the vehicle body to be painted, so that the mixed clear solvent layer 54 After the second clear paint layer 54, the color paint layer 53 and the first clear paint layer 52 are transferred to the surface of the object, the parts are mixed with a roller to drive out part of the mixed solvent and air bubbles, and are dried. After having been made, the base film is peeled off. Since it is only simple clear painting, even a person with little painting experience can easily perform painting at a certain level by performing simple transfer work. Even in a repair shop that does not perform sheet metal painting, repair painting can be performed simply by performing light sheet metal (repair) and simple clear painting and transfer operations. In addition, the color coating layer 53 is configured with the maximum number of layers in the central portion corresponding to the required area, and the peripheral portion of the central portion forms a color blurring portion in which the number of layers gradually decreases outward. In addition, the second clear paint layer 54 has the maximum film thickness at the center, and the peripheral part of the center has a clear blur part where the film thickness gradually decreases in the outward direction. Because it is configured, it can be finished so that the blurring will not be noticed even if additional clear coating is applied. Furthermore, the transfer method reduces the amount of paint applied, reduces the generation of volatile organic substances, and is significant for environmental problems.

  All the embodiments described above are illustrative of the present invention and are not intended to be limiting, and the present invention can be implemented in other various modifications and changes. Therefore, the scope of the present invention is defined only by the claims and their equivalents.
