Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for applying a coating composition onto a target workpiece in a predetermined shape and at a predetermined thickness. The present invention relates to a masking tape and a method of using the tape.

[Conventional technology]

Signboards, building walls, etc.When forming swimming pools, industrial water storage tanks, or simple skating rinks, the walls and bottom of the tank made of concrete, wood, metal, etc. are generally lined with a straight or predetermined shape. In order to apply an axe to the shape and to add waterproofness, corrosion resistance, stain resistance, etc.
Various types of tapes, such as fluororesin films, are used to provide surface material sheets.

In particular, when a facing material sheet is installed on the inner surface of a pool or water tank, the facing material sheet is, for example, as shown in Figure 1O.
Colored resin N4 such as polyethylene, face material resin 3 made of fluororesin or silicone resin is sequentially laminated on the surface of film base material 1 of polyethylene or polyvinyl chloride corner through aluminum foil 2, and adhesive 5 is applied to the back side. A structure in which the surface is coated with a release paper 6 is not used. In addition,
In the figure, 7 indicates an adhesive layer.

[Problem that the invention seeks to solve]

By pasting such a surface material sheet on the surface,
It is used in a variety of fields because it can strengthen the weather resistance and chemical resistance of the surface of the workpiece, and it can also be easily made into a water tank even if the workpiece itself is not waterproof. ,ing.

However, there is a limit to the size of the facing sheet, so for small aquariums, swimming pools, etc., several facing sheets must be strung together lengthwise.
However, in this case, for aquariums, etc., the navy blue surface material sheet:
A problem arises in that water enters between the spliced sheet and the workpiece due to capillary action or the like from the joint, causing the facing sheet to peel off. In order to solve this problem, a sealing agent called caulking agent or edge guard liquid is applied to the joints of the facing sheets and the edges of the separated facing sheets. The sealing agent d] is made of silicone resin, silicone rubber, etc., and the coating liquid often has a relatively low viscosity so that it can enter gaps and seal completely.

When applying this sealant, you want to apply it as thickly as possible to completely seal the seams, but if you apply the sealant thickly, it will run down before it hardens, making it impossible to apply it to the desired thickness. However, there is a problem that a sufficient sealing effect cannot be obtained.

Furthermore, there was also the problem that the sealant spread randomly and adhered to other parts, making it impossible to apply it in a neat line. Also, when applying sealant in a straight line, two sheets of general tape are sometimes used as masking tape with a certain distance between the coatings, but it is extremely difficult and difficult to apply it neatly and accurately. It was inefficient.

[Failure to solve the problem]

The present invention aims to provide a masking tape and a method for using the same to solve the above problems.

That is, the masking tape of the present invention is paper.

A base tape made of a plastic sheet, aluminum foil, or a laminate thereof is provided with a plurality of cutting lines such as perforations at appropriate intervals, and an adhesive is applied to the back side of the tape base. .

The present invention relates to a method for applying paint, a cooling agent, etc. onto a workpiece using the above-mentioned masking tape. Remove part of the tape according to (cutting pattern).

The method is characterized in that a coating composition is applied to the removed portion.

[Effect]

In the masking tape of the present invention, any material can be used as the tape base material, regardless of whether the coating composition is permeable to the tape base material when the coating composition is applied thereto, or which is not easily attacked by the solvent of the composition. Usually polyethylene, polypropylene.

rζ) A plastic film such as polyvinyl chloride is used, but in addition to this, ordinary paper with one surface treated with resin, nonwoven fabric, etc. can also be used. For ¥, aluminum can also be used. Furthermore, a laminated material made of an appropriate combination of paper, aluminum foil, and plastic film can also be used.

Using a transparent plastic film as the base material has the advantage of making work easier because the workpiece underneath can be seen through.

An adhesive is applied to one side of the masking tape so that it can be easily attached to the workpiece, but this adhesive does not stick to the workpiece when the tape is removed from the workpiece. It is best to use one that leaves no residue and can be easily peeled off. If necessary, it is best to attach release paper to the adhesive-coated surface and peel it off before use. However, if the tape is not very wide, it is possible to omit the release paper by using it in a roll form like duct tape or cellophane tape.

The cutting line (cut line) provided on the tape may be a perforation or a cut such as a dashed line. For example, two cutting lines extending in the length direction of the tape may be provided in the width direction of the tape so that the central portion of the tape can be removed.

The tape may be supplied in the form of Mezitape attached to the bottom surface, as will be explained in the later examples.

[Implementation fi/! l] The present invention will be explained below using examples.

FIG. 1 is a perspective view showing an example of the masking tape 11 of the present invention, showing 12 perforations.

F: This is an example in which a paper pattern 15 is attached to the lower VC chest. Figure 3 is an example in which an aluminum foil 16 and a synthetic resin 17 such as silicone resin are laminated on a plastic film 13. This is an example in which paper 18 whose surface is treated with resin 17 is used. FIG. 5 shows an example in which an adhesive 14 is applied to the back surface of a sheet of paper 8, and a release paper 15 is pasted underneath.

To use the tape of the present invention, as shown in FIG.
Face material sheet 19. Face material sheet 1 of overlapping part of 19
To protect the ends of 9.

When applying Edge Guard liquid or sealant to the edge, first apply the masking tape 11 on the facing sheet 19 as shown in FIG.
As shown in FIG.
2, apply a sealant 20 to the removed part, and remove the remaining tape llb after the sealant 20 has hardened (Fig. 6 (O to 0 diagnosis) 1° Fig. 7 (4) ) ~ 0 is an example in which the tape of the present invention] 1 was used to apply sealant 20 to fill the gap between the butting parts of surface material seam) 19.19, and the usage method is the same as the example in Figure 6. Do the same.

Figures 8 (4) to (C) are examples in which Mejitape 21 is applied to the joining portions of face material sheet 19.19, and sealant 20 is applied to both ends of this Mejitape 21.

Four perforations are made in the masking tape 1■, and the operation is carried out in the same manner as in the example shown in FIG.

FIG. 9 shows a modification of the masking tape used in the example of FIG.
A combination of tape 11 and mezitape 21 is pasted onto 9, and the sealing agent 20 is applied in the same manner as in FIG. 8 (4) to (O).

In the case of the example shown in FIG. 9, it is preferable to apply a release paper 15 covering both the tape 11 and the mejichi 1210.

In the above example, the masking tape is thin and the perforations are also provided in a straight line, but the masking tape is not limited to these examples. The perforations may also be provided in a curved or patterned manner.

〔Effect of the invention〕

As described above, in the present invention, a tape is applied to the area where a paint or a sealant is to be applied, and then a part of the tape is removed and a coating composition such as a paint or a sealant is applied to the removed area. Mejitape can be applied extremely accurately and easily, and even low-viscosity coating agents can be applied in a sharp line or desired shape without running. It has the effect of being able to apply the sealant to the desired thickness at once by applying the appropriate amount. Furthermore, as shown in FIGS. 8 and 9, by supplying the tape integrally with megitape, there is an advantage that the work can be further simplified.
