[Prior art] Conventionally, as shown in FIGS. 9 to 11, as a masking material (lp) using a foam of a thermoplastic resin such as polystyrene as a material, — > f ± L _ ^ H. It is a masking material that has holes (3P), recesses, or grooves that cover the part to be masked (2P). (Refer to patent literature 丨). [Patent Document 1]: Japanese Patent Application Laid-Open No. 62-156376 (Figures 3 and 4). Patent Documents 1 to 5 and [Summary of the Invention] [Technical Problems to be Solved by the Invention] However, among the above-mentioned conventional masking materials (1P), the thermoplastic resin is a material of a masking material (ιρ). The foam has low heat resistance. Due to the heating of the masking material (1P) during use, the masking material (lp) is greatly deformed and shrunk, so it is difficult to use the masking material. For this reason, it is not uncommon to use the masking material (1 P) once, which can no longer be used and can only be disposed of. And 'when disposing of the masking material (1P), it is carried out by incineration because of the large sigma and / or sigma sub-systems. Therefore, the gases emitted during the incineration cause atmospheric pollution or global warming. One question. [Technical solution to the problem] 315347 5 1228435 The solution to the problem is to provide a mask. The present invention is to solve the above-mentioned conventional material (1). η =. 1, dagger sheep 1 () to 80 times the thermoplastic resin foam is made of material 'and is a hole, recess (1 3) or groove (2 3) with a convex-shaped broken cover at λ Mask material (1 \ Zao Heke (1), from the outer periphery of the mask material (丨) to the hole portion (3), the recessed portion (1 3) or the sowing blood ^ Μ V trough (23) The thickness τ is set to 5 to 30 mm. A plurality is provided on the inner periphery of the hole portion (3), the concave groove (1), ~ v, ^ / concave 4 (13), or the groove portion (23). The ribs (4) of the strips are better. [Action] In the mask material ⑴ of this month, the outer circumference of the mask material 至 and the hole (3), the recess (13) or the groove (23) A thickness of ^ τ in the range of ^ to 30 mm 'can ensure that the masking material has sufficient mechanical strength, and can also reduce unnecessary thermoplastic resin materials, thereby reducing the number of masking materials. (1) The amount of waste to be treated. [Embodiment] [First example] The present invention will be described with reference to the examples shown in Fig. 1 and Fig. 3. A masking material using a thermoplastic resin foam as a material ( 1), the system is formed to have a fitting circle The cylindrical shape of the hole portion ⑺ of the masked portion ⑺ is formed on the inner periphery of the hole portion (3) with a plurality of columnar ribs (4 as shown in FIG. 丨). From this mask material (1) The thickness τ from the outer periphery to the hole portion (3) is set to 5 to 30 mm, and the diameter D of the hole portion (3) is set to be slightly equal to or slightly larger than the diameter d 'of the masked portion (2). The width w between the ribs (4) and ribs is set to be smaller than the diameter d of the masked part (2). As described above, the position D of the 315 347 6 1228435 (3) is set to be slightly equal to or It is slightly larger than the direct control d 'of the masked part (2) and the width w between the rib (4) and the rib (4) is set smaller than the diameter d of the masked part (2), thereby making the masking material ( 1) When inserted into the masked part (2), 'without hindering and easily inserting the masking material (1) into the masked part (2),' the elastic deformation of the rib (4) can be firmly fixed Fixed masking material (丨). As the material of the masking material (1), polypropylene (pp), polyethylene (PE), polystyrene (PS), and polyvinyl chloride (pvc, chlonde) are used. , Acrylonitrile_ butadiene- A thermoplastic resin foam such as ABS (butadiene-styrene), but polystyrene is the best material in terms of cost. Further, the expansion ratio of the thermoplastic resin is 10 to times, preferably 20 to 70 times, and most preferably 30 to 65 times. When using this masking material (1) for surface treatment such as painting, fit the masked part 于 before the hole (3) of the masking material (1), and then install the masked part (2) After the masking material is removed, surface treatment such as painting is performed. Then, after the surface treatment such as coating is completed, the material (1) is removed from the masked part ⑺ ...., soap ... / 一 ～ υ coat I can prevent the cover from being covered. The cover portion (2) is surface-treated. As described above, 'from the outer periphery of the masking material to the hole: the degree T 5 is 5 i 30mm, it can ensure that the masking material (1) has sufficient mechanical strength and can be made unnecessary. Thermoplastic resin material: minus. As a result, the amount of waste of masking material can be reduced. When the thickness of the spoon from the outer periphery of the masking material to the hole (3) is less than 3] 5347 7 1228435 5mm, the masking material (!) Is vulnerable to damage due to insufficient mechanical strength of the masking material (1). On the other hand, when the thickness T from the outer periphery of the mask material (1) to the hole portion exceeds 5 mm, the effect of material reduction becomes small. In addition, when the expansion ratio of the thermoplastic resin foam is 10 to 80 times, moderate elasticity can be obtained, so that the masking material (1) can be easily attached and detached. When the expansion ratio of the thermoplastic resin foam is less than 10 times, 'the masked part (2) is not easy to fit into the mask material because of insufficient elasticity. On the other hand, the thermoplastic resin foam Once the expansion ratio exceeds 80 times, excessive elasticity is obtained. Therefore, the masking material ⑴ is likely to fall off from the portion to be masked (2). Furthermore, once a rib 设置 is provided on the inner periphery (3) of the hole portion of the masking material (1), the rib (5) is easily deformed elastically, so the rib 贴 is closely attached to the outer peripheral wall of the masked part ⑺ 'For the masked area (2), the fixing force of the masking material ⑴ can be enhanced.

Compared with the j-th embodiment shown in FIG. 1 to FIG. 3, in this embodiment, a masking material made of a thermoplastic resin foam is used as a material ⑴), and there is a masked portion in a fitting cylindrical shape. ) Is a cylindrical concave portion (13), and a plurality of columnar ribs (14) are convexly provided on the inner periphery of the concave portion (13) (see FIG. 4). The thickness τ from the periphery of the masking material (11) to the concave portion (13) is the same as that of the Dibei example; 'set to 5 to 30 coffee (see Figure 4), and the concave portion ⑽ straight ㈣ set to be slightly equal to or slightly larger than the masked part (⑺ 315347 8 1228435's straight # d, and further, the width w between the rib (14) and the rib (14) is set smaller than the masked part (1 2) According to the diameter D of the recess (1 3)), the diameter d is set to be slightly equal to or slightly larger than the diameter d of the masked part (12), and the distance between the rib (14) and the rib (14) The width boundary is set to be smaller than the straight portion d 'of the masked portion (12). When the masking material (11) is inserted in the masked portion (1 2), the masked portion (12) is not obstructed and easily accessible to the masked portion ( 12) Inserting the masking material (丨 丨) in the same manner as t 'through the elastic deformation of the rib (1 4) can firmly fix the masking material (11). As the material of the mask material (Π), a thermoplastic resin foam similar to that of the first embodiment was used, and the expansion ratio of the thermoplastic resin foam was also set to be the same as that of the first embodiment. Expansion ratio. Even when the mask material (11) of this embodiment is used, the same effect as that of the first embodiment can be obtained. That is, 'by setting the thickness T from the outer periphery of the masking material (11) to the recess (13) to 5 to 3 Omm, it is possible to ensure that the masking material (丨 i) has sufficient mechanical strength and at the same time, By reducing unnecessary thermoplastic resin materials, the amount of waste of the masking material (丨 丨) can be reduced. Also, because the expansion ratio of the thermoplastic resin foam is 10 to 80 times, moderate elasticity can be obtained, and the disassembly and assembly of the masking material (11) becomes easier. Furthermore, the masking The rib (1 4) 'is provided on the inner periphery of the concave portion (i 3) of the material (11). Therefore, the rib (1 4) is elastically deformed to closely adhere to the outer peripheral wall of the masked part (丨 2).
