Description

Painting mask and method of painting using the same}

The present invention relates to a mask for painting and a coating method using the same, to prevent color mixing in the area of the boundary between different colors when painting the surface having a predetermined step and multi-color coating, the interface of different colors protrude The present invention relates to a mask for painting and a coating method capable of removing a rough feeling appearing to give a visually comfortable feeling.

In general, the coating is applied to the surface of the object in a predetermined way to block the surface and the outside of the object to prevent corrosion, decay, aging, etc. of the surface of the object, and water resistance, moisture resistance, heat resistance, chemical resistance, etc. It not only protects the object by giving it, but also has the purpose to make the surface of the object beautiful by giving color, gloss, and appearance to the surface of the object.

Such coatings are used in a wide range of fields, and in particular, to protect the surface of a device having a metallic appearance and provide a beautiful appearance, such as in the fields of automobiles, ships, motorcycles, and the like.

In recent years, the use of the multi-colored coating which forms the upper coating film which has various shapes, such as a decorative body line or a stripe, on the lower coating film is increasing.

In the multi-color coating for coating two or more colors, it is a very important problem to prevent color mixing in areas that are borders of different colors and to create sharp and smooth boundaries.

1A and 1B are conceptual views illustrating a conventional multicolor painting apparatus and a painting method using the same, and FIG. 2 is a cross-sectional view taken along the line II-II ′ of FIG. 1B.

Referring to FIGS. 1A and 2, a conventional multicolor coating coats a first paint on the surface 10 of a predetermined object and then dries to form a first paint film 20. Subsequently, a masking member 25 having a penetrating portion in the shape of the target second coating film 30 is formed on the first coating film to form the second coating film 30 of a different color from the first coating film 20.

Next, referring to FIGS. 1B and 2, after coating and drying using the second coating material, the masking member 25 is removed to form the second coating film 30 on the first coating film 20.

Looking at the conventional multi-color coating formed as described above, the second coating film 30 is produced in the form of protruding on the first coating film (20). That is, as in area A of FIG. 2, a vertical step nearly 90 degrees is formed in the first coating film 20 and the second coating film 30. There is a problem in that the surface painted by the vertical step of the interface region between the first coating film 20 and the second coating film 30 is not visually or sensationally smooth and has a feeling of being excited. In addition, the vertical stepped surface is easily broken off by an external impact (rain or wind). This results in a problem that the step becomes larger when a separate step is generated on the surface on which the coating film is to be formed, which causes more problems that the coating film easily falls off.

Therefore, in order to solve the above problems, the present invention eliminates the feeling that the painted surface is fluttering by eliminating the vertical step generated in the boundary region of the coating film, thereby providing a visually and sensory smooth feeling, and by external impact. An object of the present invention is to provide a coating mask and a coating method that can solve the problem of the upper coating film falling off.

Provided is a mask for painting comprising a barrier plate according to the present invention and a stepped member formed on the side or bottom of the boundary region of the barrier plate.

Here, the stepped member may be a plate, a line or a point having a predetermined thickness and width, and the stepped member may be formed by cutting or grinding the boundary region of the barrier plate. In addition, the boundary region of the barrier plate is preferably a through region formed through the predetermined region of the barrier plate. The upper end of the barrier plate and the lower end of the blocking member of the barrier plate of the present invention may be spaced apart by a predetermined interval or the upper end of the blocking member and the lower end of the blocking member may be spaced by a predetermined interval.

The side wall of the stepped member in the region adjacent to the boundary region may be formed in a stepped shape or an oblique shape.

In this case, acrylic, paper, plastic, metal, or magnet may be used as the stepped member, and the stepped member may be spaced apart from a side of the boundary area by a predetermined interval and surround the boundary area.

The space between the stepped member and the side surface of the boundary region is preferably about 5 mm apart.

In addition, the present invention comprises the steps of forming a first coating film using a first paint on a predetermined surface, mounting the coating mask of any one of claims 1 to 8 on the upper or boundary surface of the first coating film and It provides a coating method comprising the step of applying a second coating to form a second coating.

The forming of the first coating film may include preparing an object to be worked on, applying a primer to the surface of the object, and painting the first paint on the surface on which the primer is applied. It includes.

The coating of the second coating to form the second coating may include coating the second coating on an opening region of the painting mask, removing the painting mask, and performing a clear coating. It includes a step.

In addition, between the step of painting the second paint and the step of removing the coating mask, it may further comprise the step of applying the pearl coating.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention in more detail. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various forms, and only the embodiments are intended to complete the disclosure of the present invention, and to those skilled in the art to fully understand the scope of the invention. It is provided to inform you. Like numbers refer to like elements in the figures.

3A to 3C are cross-sectional views of a painting mask according to an embodiment of the present invention, and FIG. 4 is a bottom plan view of the painting mask of FIG. 3A.

3A to 3C, the coating mask of the present invention includes a stepped member 120 formed at a boundary between the barrier plate 100 and the barrier plate 100.

In this case, the boundary portion may be a through region 110 formed in a predetermined region of the barrier plate 100. That is, the barrier plate 100 may include a barrier plate 100 having a predetermined through region 110 and a stepped member 120 formed under the through region 110 of the barrier plate 100.

As the barrier plate 100, paper, rubber, magnetic plate plastic, acrylic, vinyl plate and thin metal plate may be used. The barrier plate 100 is preferably a plate that ensures flexibility, so that the barrier plate 100 is not affected by the bending of the surface of the material to be coated. That is, when painting the surface of the vehicle, it should be possible to expose only the area to be painted without being affected by the curvature of the vehicle body. For this purpose, it is preferable to use a plate of several mm thickness. The through region 110 formed in the barrier plate 100 is manufactured in a shape to be painted on the central region of the barrier plate 100. This first sketches the shape to be painted, and then cuts the barrier plate 100 of the sketch area using a sharp object such as a knife, a cut or a laser, to form a through area. Of course, the through region 110 can be formed using a myriad of other methods. The shape of the through area 110 may be a wide variety of shapes, including lines, figures, letters.

The area to be painted is opened on the surface of the object to be coated through the barrier plate 100, and the remaining area is shielded.

The stepped member 120 is formed of a material having a predetermined thickness, and formed to surround the through region 110 under the through region 110. This prevents the phenomenon in which the paint spreads to an area other than the area to be painted. In addition, a predetermined height difference may occur between the barrier plate 100 and the lower coating layer (the surface of the material to be coated), thereby eliminating the roughness of the interface and the vertical step. In addition, the upper end of the barrier plate 100 and the lower end of the stepped member 120 are spaced apart by a predetermined interval.

Step member 120 for obtaining the above effects can be manufactured in a wide variety of shapes and methods. That is, as shown in FIGS. 3A and 4, the stepped member 120 may be formed to be spaced apart from the through region 110 by a predetermined distance in the same shape as the through region 110. At this time, the step member 120 is formed in a square pillar shape. As a result, a predetermined stepped step is formed by the barrier plate 100 and the step member 120. A small amount of coating material flows into the stepped area to smooth the boundary region of the coating film. Of course, in addition to the square pillar, various shapes such as trapezoidal shape, rhombus shape, cylindrical shape, etc. are possible. At this time, the step member 120 may further include a separate support portion 121 in the lower edge region of the barrier plate 100 to support the barrier plate 100.

In addition, as shown in FIG. 3B, the stepped member 120 may be formed in the entire area under the barrier plate 100 so as to be spaced apart from the through region 110 by the same shape as the through region 110. In this case, a predetermined stepped portion is formed at the end of the stepped member 120 in the region adjacent to the through region 110.

In addition, as shown in FIG. 3C, the step member 120 may be formed to have a predetermined slope in the through region 110 in the through region 110 under the barrier plate 100. This slope may be in the form of an oblique line, or may be in the form of a line having a predetermined bend. In this case, the step member 120 may be formed to be spaced apart from the through region 110 by a predetermined interval. The step member 120 of the present invention is not limited to the above-described structure is possible in a variety of structures and aspects. The stepped member 120 sketches a predetermined plate in the same shape or larger than the shape of the through area 110 on a predetermined plate, cuts the plate into a sketch shape, and then cuts the cut plate into a barrier plate ( It may be formed by adhering to the bottom of 100). In addition, a line-shaped plate (string) having a predetermined thickness and width may be formed by adhering to the periphery of the through region 110 under the barrier plate in the same shape as the through region 110. In addition, in the case of a coating mask for painting a line, the stepped member 120 may be provided in the edge region of the barrier plate 100 without forming a separate through area inside the barrier plate.

The stepped member 120 may be formed in a single layer or a multilayer using various material films capable of preventing the spread of paint. That is, acrylic, paper, plastic, metal and magnet can be used. In particular, when the material to be painted is a metal, it is possible to attach the mask for painting to the surface of the lower or upper material without using a separate adhesive using a magnet as the step member 120.

The step member 120 may be attached to the object to be coated using a double-sided tape. The thickness T1 of the stepped member 120 is about 0.1 to 100 mm, and the distance T2 between the stepped member 120 and the barrier plate 100 is preferably about 5 mm. If it is out of the above range the paint may be spread in the boundary region of different colors. Most preferably, the distance between the stepped member 120 and the barrier plate 100 is about 0.2 to 1.2 mm. By the above-described spacing, the shape of the coating film to be colored can be larger than the target. Therefore, it is preferable to form the size of the through area 110 formed in the barrier plate 100 as small as the above interval.

The coating mask of the present invention can be produced without using a separate step member. This will be described with reference to the drawings.

5A and 5B are cross-sectional views of a mask for painting according to another embodiment of the present invention.

5A and 5B, a predetermined barrier mask plate 200, a penetrating portion 210 formed in a predetermined region of the barrier mask plate 200, and a predetermined blocking formed on sidewalls of the penetrating portion 210. The unit 220 is included. Since the barrier mask plate 200 and the through part 210 are the same as the barrier plate 100 and the through area 110 described above with reference to FIGS. 3A and 3C, description thereof will be omitted.

The blocking part 220 may be formed on the sidewall of the through part 210, and may be formed in a stepped step shape as shown in FIG. 5A, and may be formed in a triangular shape as shown in FIG. 5B. In the drawing, a part of the barrier mask plate 200 is cut out and formed. That is, the barrier mask in the center region of the barrier mask plate 200 is cut into a predetermined shape to form the through portion 210, and the side wall of the through portion 210 is cut or polished as shown in FIGS. 5A and 5B. To form a blocking unit 220. Of course, the present invention is not limited thereto, and a separate blocking part 220 having a predetermined step or having an oblique shape as described above may be manufactured and then attached or inserted into the side wall of the through part 220. In addition, after the through part 220 is manufactured in the shape of the target coating film, a separate barrier plate / film for shielding may be formed on the sidewall. Here, the upper end of the blocking unit 220 and the lower end of the blocking unit 220 are spaced apart by a predetermined interval.

Hereinafter, the coating method using the coating mask of this invention mentioned above is demonstrated.

6A to 6C are cross-sectional conceptual views for explaining a coating method according to the present invention.

Referring to FIG. 6A, the first coating layer 310 is formed by applying the entire coating using the first coating on the surface 300 of the object for multicolor painting.

At this time, the surface treatment is performed in a pretreatment step before the entire coating. This is to improve the protection and aesthetics of the body surface is a process to remove the contaminants such as oil, moisture, rust, dust, or the like covered with a deteriorated layer or oxide layer. If the drawings are carried out without removing these contaminants, the coating film may be peeled off due to undrying, cratering, swelling and cracking.

Thereafter, at least one of a predetermined pigment, a resin, and a solvent is mixed with the first paint, and then the mixture is coated on the surface of the pretreated object using a coating device such as an injector.

Enamel paint, urethane paint, baking paint, lacquer paint, etc. can be used as said 1st coating material. Color pigments, extender pigments and rust preventive pigments may be used. A solvent, a coarse solvent, a diluent, etc. can be used as a solvent. As the resin, all resins, synthetic resins, thermosetting resins, thermoplastic resins and the like can be used.

Thereafter, a predetermined curing is performed to dry the paint to form the first coating film 310.

6B and 6C, the coating mask 1000 is mounted on a surface of the first coating layer 310 on which the first coating layer 310 is formed, and then the second coating layer 320 is formed by painting using the second coating layer.

The openings (regions in which the second coating film is to be formed) and the lower first coating film 310 of the coating mask 1000 are spaced apart by a predetermined interval, and regions recessed to both sides of the openings (see region K in FIG. 6B) are formed. The coating mask 1000 to be used is used. The coating mask 1000 is mounted in a target area, and then, a coating masking tape (not shown) is used to shield an area not to be painted. The coating masking tape may have an adhesive region and a vinyl region for shielding to be adhered to the painting mask 1000 through the adhesive region, and may shield the entire region that the coating mask did not shield through the vinyl region. .

Thereafter, at least one of a predetermined pigment, a resin, and a solvent is mixed with the second paint, and the mixture is then coated using a coating device such as an injector. At this time, the second paint is applied to the opening area of the mask 1000 for painting, and a part of the mixture flows into the recessed areas on both sides of the opening to form a predetermined smooth curved surface or inclined surface (L in FIG. 6C). Area). By forming such a smooth interface, the step of the boundary area can be eliminated, and the surface of the multicolored paint can be manufactured with a visually comfortable feeling.

At this time, the degree to which the mixture flows depends on the amount of the solvent added to the second paint. In this embodiment, the mixture containing the second paint is used by mixing 1 to 80% of the solvent with the second paint. Through the above range, it is possible to prevent the phenomenon of spreading the mixture due to excessive flow of the mixture, and to prevent the phenomenon of curing at the same time as the viscosity is strong.

Subsequently, after removing the coating mask, the surface is polished using an abrasive and a polishing agent, and then the surface is wiped off with a clean towel, and the periphery of the fine fleece second coating layer 320 is wiped using Lakawa thinner. And transparent coating is given in order to give coating performance and gloss.

Next, the method of coating the surface of a predetermined object using the coating mask of this invention is demonstrated more concretely.

The coating method of the present invention can form a predetermined curved surface on the surface of the material having a step through a coating mask, and can eliminate the step between each layer or color when multi-layer or multi-color coating is performed. In other words, this coating method is applicable to any place where a predetermined coating film is formed on the surface, such as automobiles, furniture, home appliances, ships, airplanes, buildings, roads, and the like.

Moreover, in such a coating method, solid coating which forms a single film | membrane, two-tone coating which performs a base and clear coating, or three-tone coating which performs pearl coating can be performed.

First, the solid painting will be described. Solid painting refers to painting the mixture of the color of the base and the shine of the gloss paint at once by using a painting device. Since the painting is to be done on the material to be coated at once, it may be applied to the primer and the coating is not applied to the primer. You can paint two or more colors on the material. That is, although the foregoing description has been made of forming the second coating film on the first coating film, in the following embodiment, one area of one surface is painted with a solid paint, and the other area is coated with a solid paint. In the description, the boundary line will be described.

For example, suppose you want to paint red on one side and black on the other.

First, the area to be painted is shielded by using the coating mask of the present invention. The red is then painted with a solid paint and dried. Next, after installing the coating mask of the present invention along the red paint side boundary line, after removing the coating mask installed in the black coating area, black solid coating is applied to black and dried. Finally, if the mask for the paint installed in the red paint area is removed, the two colors are painted horizontally without a step.

In the case of using such a solid coating and a mask for painting, it is possible to paint horizontally without a boundary step, which is various multicolor coatings.

Next, the two cord base coating and the three coat pearl coating will be described.

7A and 7B are flowcharts for explaining a painting method according to the present invention.

Looking at the two-coat base coating with reference to Figure 7a as follows.

First, a predetermined object such as a panel, plastic, wood, etc. to be prepared is prepared (S10). Then, to prevent bending or gas, oxidation, corrosion and the like, and to apply the primer to facilitate the adhesion of the base coating to be carried out through the subsequent process (S20). After polishing and drying the primer, the base coating (color coating) is carried out (S30).

After the base coating is dried, the coating mask of the present invention is installed on the desired surface of the upper part of the base coating (S40), and monochromatic coating is performed using the coating apparatus (S50). After monochromatic coating, the mask for painting is removed (S60), and the coating is dried. After drying, predetermined polishing is carried out using a varnish compound, followed by wiping with a degreaser, a lacquer or a thinner. Finally, clear clear is applied (S70) to complete the two coat base coating.

Looking at the three-coat pearl coating with reference to Figure 7b as follows.

First, prepare an object such as a panel, plastic, wood to work (painting) (S110). The primer is applied (S120), and the base color is coated (S130). The coating mask is installed in a predetermined area on the base-coated upper surface (S140), the monochromatic coating is performed (S150), and then pearl coating is continuously performed (S160). After the pearl coating, the coating mask is removed (S170), a predetermined portion is polished with a compound, wiped with a degreaser or laca thinner, and then transparent clear is coated (S180) to complete the three coat pearl coating.

As described above, in the present invention, a vertical space generated in the boundary region of the coating film is provided by placing a stepped member spaced a predetermined distance below the opening area of the coating film shape in the mask to be coated to leave a predetermined space between the mask and the surface of the lower surface. By eliminating the mold step, the impression that the painted surface is flung can be eliminated, which can give a visually and sensually smooth feeling.

In addition, it is possible to eliminate the problems caused by the stepped surface (painting or lifting).
