Abstract

(57) [Summary] [Purpose] A masking sheet that can be used even if the masking surface is curved. [Structure] A masking sheet 1 is obtained by forming tin into a foil shape and providing an adhesive layer 2 on the back surface thereof. Since tin is very soft in nature and rich in elasticity, it realizes a plasticizing action according to the shape of the masking surface and adapts to the masking surface without the end face jumping up and distortion.

[0001]

[Industrial applications]

 The present invention relates to an improved creation of a masking sheet used in painting work, and more particularly to creation of a masking sheet that can be used even when the masking surface is a curved surface.

[0002]

[Prior Art]

 It is widely practiced to mask the non-painted surface with a sheet when applying a brush or spraying. A masking sheet has heretofore been known in which an adhesive layer is provided on the back surface of paper or a synthetic resin sheet for this type of application, and the adhesive layer is temporarily attached to a desired masking surface.

[0003]

[Problems to be solved by the device]

 However, although there is no problem when the masking surface is a flat surface, when it is a curved surface, even if an attempt is made to attach a masking sheet to the curved surface, the masking sheet does not fit well to the curved surface. That is, due to the resilience of the material of the masking sheet itself, the end surface of the masking sheet bounces up, and distortion causes wrinkles on the surface, resulting in poor masking effect. In addition, this resilience also has an adverse effect when cutting unnecessary parts from the attached masking sheet with a cutter, etc., resulting in the phenomenon that the cutting end face is blunted or rises in a wavy shape when passing through the cutter. Even if the surface is a flat surface, there is a problem that the paint enters from here.

[0004]

[Means for Solving the Problems]

 The purpose of this invention is to solve the above-mentioned problems of the masking sheet of the prior art. The tin is used as the material of the masking sheet, and it is formed into a foil, and an adhesive layer is provided on the back surface of the tin. It is characterized by

[0005]

[Action]

 In other words, tin is extremely soft in nature and rich in elasticity, so when it is formed into a foil shape and pressed against the masking surface, a plasticizing action is realized according to the shape of the masking surface, and the end face bounces up or is distorted. It produces the effect of adapting to the masking surface without occurring.

【Example】

 Specific embodiments of the masking sheet of the present invention will be described below with reference to the accompanying drawings. 1 and 2 show an example in which the masking sheet 1 of the present invention is used for a coating object M having a curved shape (here, a sphere is assumed). The masking sheet of this invention is a foil-shaped sheet made of tin by spreading and the like. Therefore, in this embodiment, the thickness is 10 μm. Reference numeral 2 in the figure is an adhesive layer provided on the back surface of the sheet, and is set to an adhesive force such that it can be easily peeled off. The above masking sheet 1 is adhered to the masking surface of the object M to be coated to form the masking layer 1a. In this case, the surface of the masking sheet is sufficiently pressed to plasticize the masking sheet so as to follow the shape of the masking surface. At the same time, it is necessary to work to discharge the air that has accumulated between the masking surface and the masking surface. After the above work, the masking layer 1a is applied to the object M to be coated by cutting off the unnecessary portion 1b from the attached masking sheet 1 with a cutter or the like. Incidentally, reference numeral 1c in the drawing denotes a cut end surface of the masking sheet 1.

[0007]

[Effect of the device]

 The present invention having the above configuration has the following unique effects. Since the masking sheet itself plasticizes according to the shape of the masking surface, it is possible to mask any curved surface. In the case described above, even if wrinkles are generated, if the pressure is applied more strongly than the plasticity of the masking sheet, the wrinkles are crushed and eliminated. The masking sheet has no elastic restoring force, and because the material is soft, the cut end face does not rise in a wavy shape even when cut with a cutter, and it is smooth, so there is no risk of ingress of coating material. Due to the above effects, the applicable range of the masking sheet is expanded and contributes to the improvement of the efficiency of painting work.
