JPS6182869A - Masking method during painting work - Google Patents

Abstract

PURPOSE:To execute masking with easy procedure by applying a duplicated adhesive tape to an unpainted area of an object to be painted wherein a pressure-sensitive adhesive layer is formed to a half area of one side of the tape with another half area of the same side of the tape being left uncoated with the adhesive, and the rear side of the coated area of the tape being uncoated but the rear side of the uncoated area being coated with the pressure- sensitive adhesive. CONSTITUTION:A duplicated adhesive tape 6 is prepd. by forming a pressure- sensitive adhesive layer 5 on one half area of a base 2 of the tape leaving another half area 8 uncoated with the adhesive, and the rear side of the pressure-sensitive adhesive layer being left uncoated and the other half of the rear side being coated with the adhesive layer. The tape is adhered to a boundary line between the area to be painted and unpainted so as to coincide a side edge of the tape to the boundary line, and a side edge of a film is adhered to the adhesive layer on another side of the tape. By this method, an efficient painting work is executed.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a curing method for covering non-painted areas with a film-like curing material during painting work to prevent paint from adhering to the non-painted areas. It is something.

(Prior art and its problems) The conventional curing method during painting work is to use a sheet of paper such that the side edge is located slightly on the side of the non-painted 6I area from the boundary line between the painted area and the non-painted area of the painting work surface. With a film-like curing material made of plastic film or other suitable material applied to the non-painted area, apply a single-sided adhesive tape to the border line and the curing material side so that one side of the tape matches the border line. The method was to paste it over the edges. In this conventional method, the curing material must be held at a predetermined position and the adhesive tape must be applied to the predetermined position at the same time, making the work extremely difficult and inefficient.

In order to solve the above-mentioned problems, a curing material with an adhesive tape has been considered, in which an adhesive tape is pasted on the side of the curing material in advance so that the adhesive layer partially protrudes from the side of the curing material. However, there are many problems, such as not being able to use existing paper and polyethylene film, and high curing costs. The curing method according to the present invention is characterized by forming an adhesive layer on one side of the tape along at least one side, and forming an adhesive layer on the other side of the tape. Prepare a double-sided adhesive tape on which an adhesive layer is formed leaving an exposed part of the tape base material along one side, and apply the tape to the boundary line between the painting area and the painting area of the painting work surface. A film-like curing material that aligns one side and attaches the tape to the non-painted area using the adhesive layer on one side, and then places the tape on the adhesive layer on the other side of the tape to shield the non-painted area from the paint. It is at the point where the sides of the are pasted.

(Example) First, the double-sided adhesive tape used in the method of the present invention will be explained.

The double-sided adhesive tape 1 shown in FIG. 1 and FIG. It is configured. The adhesives N5.6 each have a width that covers approximately half an area in the tape width direction, and are located at opposite positions to each other in the tape width direction. In addition, each adhesive layer 5.6
The exposed base surface portion 7.8 adjacent to the base material surface is subjected to a treatment similar to the back surface treatment of conventional single-sided adhesive tape, and when this tape 1 is wound into a roll, the exposed base surface portion 7. .8
and adhesive 1'iJ5. 6 from adhering to each other. Further, adhesive J is applied on the base material 2.
! is, 6 or when the exposed portion 7.8 of the base material surface is subjected to the back surface treatment as described above, depending on the material of the base material 2, an undercoating treatment is applied to the base material surface in a conventionally known manner.

To explain the curing method of the present invention using the double-sided adhesive tape 1 configured as described above, first, as shown in FIG. Among both sides +a and Ib of the tape 1, one side 1a (or the adhesive N6) coincides with the edge of the adhesive layer 5.
The tape 1 is pasted onto the non-painted area 11 using the adhesive layer 5 (or the adhesive layer 6) so that the other side +b) coincides with the edge of the tape 1. When applying this tape 1, the exposed base surface portion 8 (or exposed base surface portion 7) of the tape 1 can be pressed with a fingertip, so that the work can be done in almost the same way as with conventional single-sided adhesive tape.

Once the tape 1 has been applied to the painting work surface 9 as described above, a film-like curing material 13 made of a suitable material such as paper or plastic film is then applied as shown in FIG.
The adhesive layer 6 of the tape 1 is made such that one side 13a does not protrude beyond the boundary +1t9t12 toward the painting area 10.
(or the adhesive/material layer 5), and the non-painted area 11 is appropriately covered with the curing material 13.

Note that the double-sided adhesive tape used in the method of the present invention is not limited to those of the above embodiments6 For example, as shown in FIG.
It is also possible to use a double-sided adhesive tape 18 that is integrally adhesively bonded to each other using one side of 6 and 17. Further, for example, the adhesive layers 5 and 16 are adhered to the painting work surface 9, and the adhesive layer 6
．． 17 is attached to the curing material 13, when the adhesive layer is used with a specific adhesive partner, the adhesive layers on both sides of the tape should not be made of the same adhesive, and should be made depending on the material or surface condition of the adhesive layer. It can be constructed using different adhesives that are compatible with each other. Furthermore, the adhesive strength of the adhesive layer adhered to the painting work surface 9 and the adhesive strength of the adhesive layer adhered to the curing material 13 can be adjusted by changing the type of adhesive used and the width of the adhesive layer. For example, when the curing material 13 is peeled off after the painting work is completed, the tape is always attached to the curing material 1.
It is also possible to peel it off from the painting work surface 9 while remaining on the 3 side.

(Operations and Effects of the Invention) The curing method for painting work according to the present invention can be implemented as described above, and according to the curing method of the present invention, only adhesive tape is applied to the painting work surface. When applying the tape, you can use the exposed part of the base material directly behind the adhesive layer to take pictures of the tape and adjust the tape position in the same way as with general single-sided adhesive tape.
You can also press and slide your fingertips on the tape to obtain a strong adhesive effect, so apply one example of the adhesive tape exactly on the boundary line between the painted area and the non-painted area. This is extremely simple and easy to do. In addition, when pasting the curing material after pasting this tape, the position of one side of the curing material does not require much precision, so conventional curing is performed by preparing the adhesive tape and the curing material separately. Compared to other methods, the entire work is extremely simple and easy to perform, and it also helps improve work efficiency.

Moreover, compared to the case of using conventional curing material with adhesive tape, the desired purpose can be achieved at low cost by utilizing existing curing material. Of course, compared to the case of using a general double-sided adhesive tape in which an adhesive layer is formed on the entire front and back surfaces of the tape, it has the advantage of being easier to work with and can be carried out at a lower cost.
