Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a coating method using a transfer mark combined with masking.

[Conventional technology]

Figures 8 to 11 show a conventional painting method for painting a pipe that has been coated with an intermediate coat by using a combination of transfer marks and painting.First, as shown in Figure 8, pipe A Topcoat 1 is applied to zone B on one end side of the outer circumferential surface of the transfer mark bordering the position where the transfer mark is attached.

At this time, the mist powder of the top coat 1 of zone C on the other end side will adhere.

Next, as shown in Fig. 9, a pressure-sensitive heat-sensitive transfer mark 2 is pasted at a predetermined position on the pipe A, and after peeling off the mount 3, the entire surface is overcoated with clear lacquer, acrylic, melamine, urethane, epoxy, etc. The transfer mark 2 is stabilized by applying, baking, etc.

Next, as shown in FIG. 10, masking 4 is performed on the stabilized transfer mark 2 using tape, paper, or the like.
At this time, the masking 4 must be applied accurately to match the shape of the end facing the zone C on the other end side of the transfer mark 2, which requires skilled technique and time.

Apply a topcoat 5 of another color to the zone C on the other end side where the masking 4 has been applied as described above, and after drying such as baking to stabilize the masking 4.
By peeling it off and applying an overcoat to the entire surface, transfer mark 2 and paint 1, as shown in Figure 11, are created.
A pipe coated with three colors is obtained by step 5.

[Problem to be solved by the invention]

By the way, the conventional painting method described above requires multiple layers of paint and the edges of the masking must be accurately finished to match the shape of the transfer mark, which makes work efficiency extremely low. There are problems in that productivity is poor, the defect rate is high due to repeating the same process, and the finish is heavy and unsightly due to multilayer coating.

This invention was made in order to solve the above-mentioned problems, and is a transfer mark combined with masking that can improve productivity by simplifying the painting process and reduce painting costs. The purpose is to provide a coating method using

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention has been developed by pasting a masking mount with a transfer mark on the surface and an adhesive layer on the transfer mark to the object to be painted with the adhesive layer, and then attaching the adhesive layer to the object to be painted. Masking is applied to a part so as to overlap with the mount, the masking is removed after painting the exposed part of the object to be painted, and then the mount is peeled off from the transfer mark.

[Effect]

A transfer mark mount is pasted on a predetermined position of the object to be painted using an adhesive layer, a part of the object to be painted is masked so that it overlaps with the mount, and when the exposed part of the object is painted, the mount is transferred. By using mark masking in combination, after removing the masking and then peeling off the mount from the transfer mark, multicolor painting can be performed by combining the transfer mark and painting.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 7 of the attached drawings.

Figures 1 and 2 show a mount for use with masking and a transfer mark on one side.
A pretreatment layer 12, a mark layer 13, and an adhesive layer 14 are sequentially laminated on the surface of the mount 11, and an extension 15 protruding from the mark layer 13 is provided at the end of the mount 11. An adhesive layer 16 is provided for temporary fixing to prevent peeling, and a release sheet 17 for protecting the adhesive layers 14 and 16 is overlaid on the surface of the extension 15 from the mount 11.

The mount 11 is formed to have the same shape as the outline of the mark layer 13 except for the extension 15, and has a function as a masking agent during painting.

The mount 11 is made of heat-resistant polyester,
The peel strength of the release-treated layer formed using a synthetic resin film such as polyethylene, acrylic, or paper of appropriate thickness, and applied to the surface is set to, for example, about 60 to 78%.

The pretreatment layer 12 adheres the mark layer 13 on the surface release treatment layer of the mount 11, and since it will remain on the surface of the mark layer 13 after the mount 11 is peeled off, the pretreatment layer 12 will take advantage of changes over time. mark layer 13
In addition, when a coating is applied on the mark layer 13, the crosslinking reaction is used to firmly harden and fix the mark layer 13. For example, it is made of heat-resistant acrylic resin, etc. Using transparent or translucent ink or paint as a main component, it is provided on the entire surface of the mount 11 or in parts in a pattern equal to that of the mark layer 13. In addition,
This pretreatment layer 12 may not be provided.

The mark layer 13 is formed using ink or paint whose main component is an acrylic resin or the like that has heat resistance, weather resistance, and solvent resistance, and can be formed by various printing methods such as planography, screen, convex, intaglio, and gravure, or by spraying. Desired colors and patterns such as patterns, designs, and letters are applied by painting or the like.

The adhesive layer 14 is a heat-resistant, ultra-high viscosity type mainly made of acrylic resin, etc., and can be directly attached to the transferred object without using a solvent. 13
The mark layer 13 is provided thereon by the same means as the mark layer 13.

Release sheet 17 that protects the adhesive layer 14
is made by applying silicone processing to one side of synthetic resin or paper to improve mold release properties, and the peel strength of the mold release treatment layer is set to about 80 to 100%, so that the adhesive layer 14 is not damaged. It is now possible to perform peeling without applying any damage.

In addition, if the mount 11 is made transparent or semi-transparent, and lines for positioning are printed in advance on the margins,
The pasting position of the mark layer becomes accurate.

Next, the multicolor coating process will be explained using FIGS. 3 to 7.

The drawing shows an example of applying multicolor painting to a pipe. First, as shown in Fig. 3, a mount 11 is pasted on a predetermined position of the pipe A with an adhesive layer 14, and then the mount 11 is used as a border. Masking 18 is applied to zone B on one end side of pipe A so as to partially overlap with mount 11, and painting 19 is applied to zone C on the exposed other end side of pipe A, as shown in FIG. Painting 1
9, the mount 11 serves as a mask for the mark layer 13, and when the coating 19 is dried by baking or otherwise stabilized, the mark layer 13 is also stabilized.

Next, the masking 18 is removed, and as shown in FIG. 5, a masking 20 is applied from the dried coating 19 to the mount 11, a coating 21 is applied to the exposed zone B on one end side, and the coating 21 is baked, etc. After the mark layer 13 is stabilized by drying, the mount 11 is attached to the treated layer 12 as shown in FIG.
By peeling it off from the mark layer 13 at the part shown in FIG.
As shown in the figure, three-color coating can be applied using the transferred mark layer 13 and the coatings 19 and 21 on both sides, and if necessary, the entire outer surface can be coated with clear lacquer, acrylic, melamine, urethane, epoxy, etc. An overcoat may be applied and baked.

Adding an overcoat creates a more unified look.

In the case shown in the figure, the mark layer 13 is transferred so as to be wound around the entire length of the outer circumference of the pipe A, but for example, the mark layer is pasted with a mount along the axial direction of the pipe A, and the middle of the mark layer is pasted as a border. Alternatively, the outer peripheral surface of the pipe may be painted in a different color. Also,
The adhesive layer 16 may be used not only for positioning as shown, but also for preventing peeling of the end of the mount 11 wound around the pipe A.

Furthermore, the present invention is not limited to painting pipes as in the illustrated embodiment, but can also be applied to flat surfaces.

[Effect] As described above, according to the present invention, a transfer mark is affixed to an object to be painted together with a mount, masking is applied to the object to be painted so that it overlaps with the mount, and after painting is applied to the exposed portion of the object to be painted. Since the masking is removed and the mount is peeled off from the transfer mark, the mount can be used as is as a mask for the transfer mark in multi-color painting using transfer marks, dramatically increasing productivity by reducing the painting process. This makes it possible to reduce production costs.

In addition, since the mount also serves as masking, advanced techniques are not required for masking work, and the work can be done with low cost and labor.
