Abstract

PURPOSE:To facilitate a masking work, and to improve the reliability of the adhesive capacity at the time of heating by allowing masking pattern paper to have a pressure sensitive adhesive layer applied to roughly the whole surface of the side on which a parting tape is stuck and separating paper, and providing a cutting line for cutting off its peripheral part on the separating paper. CONSTITUTION:At the time of executing masking by using a masking material, a mark 11 is put on several places in order to display the position of a parting line 12 on the surface 10 to be painted, and the masking material consisting of a parting tape 8 and masking pattern paper 1 having separating paper is stuck to the surface 10 to be painted so as to be aligned with the mark 11 after peeling off the separating paper of the parting tape 8. In this regard, as for the side for which the parting tape 8 of the masking pattern paper 1 is not attached, it is also possible that the separating paper extending from the end of the side to a cutting line 4 is peeled off and stuck to the surface 10. In such a case, since the separating paper of the inside from the cutting line 4 is used in a state that it remains stuck to the masking pattern paper 1, the masking pattern layer always has moderate rigidity, and can be handled easily.

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a masking material for multicolor painting.

[0002]

2. Description of the Related Art Conventionally, a parting tape and a masking paper have been used for painting a two-tone color automobile body, for example. The masking operation using the parting tape and masking paper, the boundary line of the coating color in advance on the surface to be painted (hereinafter, referred to as parting line) at a predetermined position, after sticking the parting tape along the parting line, The masking paper is attached on the parting tapes.

However, when the parting line is curved or when both ends of the coated surface are long, it is difficult to accurately apply the parting tape due to slack or elongation of the tape. Therefore,
For the purpose of solving the above-mentioned drawbacks, there is also used a masking paper in which a parting tape is preliminarily attached to one end by a double-sided adhesive tape (actually, 2-91672).
(See the official gazette).

However, in the conventional integrated masking material, the double-sided adhesive tape is used to attach the parting tape to the masking pattern paper laminated with the resin sheet.
The reliability of sticking is low, and there is a problem that the masking pattern paper falls off from the parting tape, especially when heated in the baking step after painting. In addition, since the integrated product has a large size, the rigidity of the masking material tends to be insufficient, which is disadvantageous in handling.

The present invention has been made in view of the above-mentioned problems in the conventional integrated masking material, and the adhesive strength between the parting tape and the masking material is large and highly reliable, and the rigidity of the masking material is high. It is an object to provide a masking material integrated with a parting tape.

[0006]

The present invention relates to a parting tape having a pressure-sensitive adhesive layer on one surface of a base material and a release paper laminated thereon, and a base material surface of the parting tape opposite to the pressure-sensitive adhesive layer. And a masking pattern paper laminated with a heat-resistant adhesive layer, and the masking pattern paper has a pressure-sensitive adhesive layer applied on almost the entire surface where the parting tape is laminated and a release paper laminated on the adhesive layer. However, the present invention relates to a masking material for multicolor coating in which a release line is provided on the release paper to cut out the peripheral portion thereof.

[0007]

The masking material of the present invention has a high rigidity and is easy to work since a pressure sensitive adhesive is applied on one side and a release paper is provided on the pressure sensitive adhesive, and the parting tape is a heat resistant adhesive. Since they are pasted together, they are highly reliable against heat.

[0008]

The masking material of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of the masking material of the present invention.

In FIG. 1, the pressure-sensitive adhesive layer 6 is formed on one surface of the substrate 5.
The parting tape 8 having the release paper 7 and the release paper 7 attached thereon is attached to the masking paper 1 with the heat-resistant adhesive layer 9 on the side opposite to the adhesive layer 6 of the base material 5. The masking pattern paper 1 has an adhesive layer 3 and a release paper 2 attached on the adhesive layer 3 on almost the entire side where the parting tape 8 is attached. The release paper 2 has a peripheral portion to be cut off. A perforation line 4 is provided.

As the base material of the parting tape, those conventionally used can be used, but it is preferable to use a polyester film such as polyethylene terephthalate.

The parting tape base material and the masking pattern paper are bonded with a heat-resistant adhesive which is generally used.

The masking pattern paper may be a paper laminated with a resin film which has been conventionally used, but when crepe paper is used as the masking pattern paper, the paint on the back surface of the masking pattern paper is removed when the masking material is peeled from the surface to be coated. This is preferable because it does not cause a problem in the process such as flaking, peeling, scattering, and reattaching to the coated surface. The cut line provided on the release paper is usually provided as a cut about 0.5 to 1.5 cm from each side.

In this way, the masking pattern paper which is supported by the release paper and the parting tape over the entire back surface is
Appropriate rigidity is given, and it is possible to hold a predetermined shape in advance.

As the pressure-sensitive adhesive for the pressure-sensitive adhesive layers 3 and 6, those commonly used can be used, and examples thereof include natural rubber-based, synthetic rubber-based, and acrylic rubber-based pressure-sensitive adhesives.

In order to perform masking using the masking material of the present invention, as shown in FIG. 2, marks 11 are added in places on the surface 10 to be coated to indicate the position of the parting line 12. Then, a masking material composed of the parting tape 8 and the masking template 1 having the release paper 2 is applied to the parting tape 8
After the release paper 7 is peeled off, it is attached to the surface 10 to be coated so as to be aligned with the mark 11. For the side of the masking paper 1 on which the parting tape 8 is not attached, the release paper 2 in the part from the edge of the side to the cut line 4 can be peeled off and attached to the surface to be coated. At that time, since the release paper 2 on the inner side of the cut line 4 is used as it is attached to the masking paper 1, the masking paper 1 always has appropriate rigidity and is easy to handle.

[0017]

The masking material of the present invention is provided with the release paper over the entire back surface of the masking template, so that appropriate rigidity is imparted to the entire masking material.
Excellent workability. In addition, since the parting tape and the masking paper are integrated with a heat-resistant adhesive, the masking work is easy and the reliability of the adhesive capacity at the time of heating is higher than that of the conventional product that uses double-sided adhesive tape. Is high.
