The expansion ratio of the thermoplastic resin is 10 to 80 times, preferably 20 to 70 times, and most preferably 30 to 65 times. When using this masking material ⑴ to apply a surface treatment such as painting dress, the masked area ⑽ is fitted to the hole of the masking material ⑺, and then the masked area (2) is installed and the masking material ⑴ is applied. Perform surface treatment such as painting. Then, after the surface treatment of Tu Sang and the like is completed, the mask is removed from the masked part ⑺ and the surface treatment such as painting is performed by using the masking material 如此 in this way to prevent the masked part ( 2) Surface treatment. As described above, from the outer periphery of the masking material 至 to the Hi factory of the hole portion (3) is: to 30 °, the masking material can be ensured to have sufficient strength and wide strength, and at the same time, Reduce unnecessary thermoplastic resin materials. As a result, the amount of waste of masking material can be reduced. When the thickness T from the outer periphery of the masking material 至 to the hole portion (3) is less than 3J5347 200418577 5_, 'the mechanical strength of the masking material 不足 is insufficient', the masking material 易 is vulnerable to damage, and- When the thickness T of the outer periphery of the cover material 至 to the hole portion (3) exceeds 5 mm, the material reduction effect becomes small. Further, when the expansion ratio of the thermoplastic resin foam is 10 to 80 times, moderate elasticity can be obtained, so that the masking material ⑴ can be easily disassembled and attached. When the expansion ratio of the thermoplastic resin foam is less than 10 times, due to insufficient elasticity, the masked portion (2) cannot be easily fitted into the masking material (!). On the other hand, the thermoplastic resin foams. Once the foaming ratio of the body exceeds 80 times, excessive elasticity is obtained, so that the masking material ⑴ is likely to fall off the masked part (2). Furthermore, once a rib (4) 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 (sentence is close to the part to be masked ( The outer peripheral wall can increase the fixing force of the masking material (1) to the masked portion (2). [Second Embodiment] Other embodiments are shown in Figures 4, 4 and 5. Relative Table 帛The i-th embodiment shown in FIG. 1 to FIG. 3, in this embodiment, a masking material (1 1) made of a thermoplastic resin foam body has a masked portion (1, 2) having a κ ΰ cylindrical shape. ) Is a cylindrical concave portion (1 3), and a plurality of columnar ribs (14) are convexly provided on the inner periphery of the concave portion (1) (refer to FIG. 4). The outer periphery of the masking material (] 丨) reaches the concave portion ( 13) The thickness D is the same as in the first embodiment, and is set to 5 to 30. (refer to FIG. 4), and the depression D of the 卩 (] 〇) is set to be slightly equal to or slightly larger than The masking part () 2) 315347 8 200418577 is directly controlled by d '. Furthermore, the width w between the ribs (14) and ribs (14) is set to a small square, and the diameter d of the masked part (12) is in accordance with The recess (〖3)) The diameter D is set to be slightly equal to or slightly larger than the diameter d of the masked portion (12), and the width w between the rib (14) and the rib (14) is set smaller than that of the masked portion (12). The diameter d is the same as in 4, when the masking material (11) is inserted into the masked part (12), without obstructing and easily inserting the masking material (11) into the masked part (12), The elastic deformation of the rib (14) can firmly fix the masking material (〗 1). The material of the masking material (10) is the same as in the first embodiment: a thermoplastic resin foam is used. The expansion ratio of the thermoplastic resin foam is also set to be the same as that in the first embodiment. Foaming magnification.-Even if the masking material (11) of this embodiment is used, the same effect as that of the jth embodiment can be obtained. That is, from the outer periphery of the masking material (11) to the Setting the degree T of the recess (13) to 5 to 30 mm can ensure that the masking material ⑴) has sufficient mechanical strength 纟 'while also reducing unnecessary thermoplastic resin materials, which can also reduce The amount of waste material for the mask material (1 1}. In addition, because the expansion ratio of the thermoplastic resin foam is 丨 0 to times, it can be dismantled to obtain a moderate elasticity. 〇 Furthermore, since ribs are provided on the inner periphery of the recessed portion of the mask material (11), the ribs (14) are elastically deformed, so that f is covered and η = the peripheral wall. (] 2) The masking material can be strengthened. ⑴) [Younger 3 examples] 315347 9 200418577 is shown in Figures 6 to 8. Other embodiments. Compared with the i-th embodiment shown in Figs. I to 3, in this embodiment, a masking material (21) made of a thermoplastic resin foam is provided with a masked portion (22) in a flat shape. ), A plurality of columnar ribs (24) are protruded from an inner peripheral side wall of the groove portion (23) (see FIG. 6). The thickness T ′ from the outer peripheral side wall of the masking material (21) to the groove portion (23) is “set to 5 to 30 mm (see FIGS. 7 and 8)” as in the i-th embodiment. The width% of the groove portion (23) is set to be slightly equal to or slightly larger than the width w of the material portion (22), and the width WS between the rib (24) and the rib (24) is set to be smaller than the covered portion ( 22) The width w is set to be slightly equal to or slightly larger than the width w 'of the masked part 依 and the width w between the ribs (24) and (24) is set to be smaller than The width w of the masking part is “when the masking material is inserted into the masked part (22)”, while the masking material (2i) is easily inserted into the masked part (22). The material (21) can be firmly fixed by the elastic deformation of the ribs (24). For the material of the masking material (21), the same foaming resin as the thermoplastic resin of the i-th embodiment is used. The foaming ratio of the foam body is also set to harmonious! The same expansion ratio was obtained in the examples. Even when the mask material (21) of this embodiment is used, the same effect as that of the first embodiment can be obtained. That is, by setting the thickness D from the outer peripheral side wall of the masking material (21) to the groove portion (23) to 5 to 30 mm, it is possible to ensure that the masking material (21) has sufficient mechanical strength and can also By reducing the amount of unnecessary thermoplastic resin material 315347 10 200418577, the amount of waste of the masking material (21) can be reduced. In addition, since the expansion ratio of the thermoplastic resin foam is 10 to 80 times, moderate elasticity can be obtained, and disassembly and assembly of the masking material (21) becomes easy. Furthermore, since a rib (2 4) is provided on the inner peripheral side wall of the groove portion (23) of the masking material (2 1), the rib (24) is elastically deformed and closely adheres to the masked portion (22). The outer peripheral wall can enhance the fixing force of the masking material (21) to the masked portion (22). The embodiments of the present invention have been described above according to the examples, but the scope of the present invention is not limited to this, and may be changed or deformed according to the purpose described in the scope of the patent application. [Effects of the invention] In the present invention, since the masking material has sufficient mechanical strength and can reduce unnecessary thermoplastic resin materials, the amount of waste of the masking material can be reduced. Alleviates air pollution and global warming during incineration.
