[Prior art] Conventionally, as shown in FIG. 7 and FIG. 8, a masking material (丨 p) composed of a foam of a thermoplastic resin such as polystyrene is generally provided with a hole facing the protection object. A solid masking material (1P) composed of an inserting portion (3p) of a portion or a recessed portion (2p) and a head (4p) provided at the root end of the inserting portion (3P). (Refer to Patent Document 1). [Patent Document 1] Patent Document 1 · Japanese Patent Laid-Open Publication No. 62-199173 (pages 4 to 7, page 1) [Summary of the Invention] (Problems to be Solved by the Invention) Among the masking materials (lp), the thermoplastic resin foam of the material of the masking materials (ιρ) has low heat resistance. The heating of the masking materials (lp) during use will make the materials (lp) # 很The deformation and shrinkage of A make it difficult to recycle the masking material. For this reason, it is not uncommon for the used mask material (1P) ′ to be recycled and can only be disposed of. However, when disposing of the masking material (1P), it is almost performed by a combustion process'. Therefore, the gas discharged during the combustion process has a problem that it may be one of the causes of air pollution or global warming. (Solution to solve the problem) 315348 5 1234489 The present invention provides a method for solving the above-mentioned conventional problems, and provides a mask made of a thermoplastic resin foam ^ soap material (1, 11), and The pores or recesses (2, i2) that are to be protected are quaint and have insertion portions (3, 13), and the cavity portions (6, 16) are formed from the periphery through a predetermined thickness. The expansion ratio of the thermoplastic resin foam is 10 to 80 times, and the thickness from the outer periphery to the peripheral wall of the cavity portion (6, 16) is preferably 5 to 3 mm. A plurality of ribs (5, 15) are preferably provided on the periphery of the insertion portion (3, 13). [Action]-In the masking material ⑴ of the present invention, by providing the masking material 空 with an empty part (6) ', savings in the thermoplastic resin material can be achieved. That is, since only the cavity portion (6) is required, the thermoplastic resin can be reduced, and the amount of waste of the masking material (1) can be reduced. [Embodiment] [Example 1] The present invention will be described with reference to the examples shown in Figs. 1 and 2. A masking material (1) composed of a thermoplastic resin foam is composed of an insertion portion (3) opposite to a hole or a recess (2, 12) of the object to be protected, and a head portion ( 4), wherein a plurality of square column-shaped ribs (5) are convexly provided on the periphery of the insertion portion (3), and the periphery of the insertion portion (3) is formed by a predetermined thickness T to form a cavity Acupoint (6) (see Figure 1). The insertion part (3) of the masking material (1) is formed into a conical shape corresponding to the circular hole-shaped recess (2), and the diameter D of the tip of the insertion part (3) is set to be slightly smaller than the straight fd of the recess (2). , The diameter of the root end of the insertion part (3) is set to be slightly larger than the diameter cKD ^ cKDj of the recess 6 315348 1234489 part (2). According to Zhao Muu, for this conical shape, in order to keep the mask fixed when the mask material (, = mask material ⑴ insertion part ⑺ forming material) is not as far as possible from the recess (2) ^ to the recess (2). 丨() Delo, hunting firmly by its elastic rebound force, the ^ ^ taxi η /-of the masking material (!) Is formed slightly larger than the insertion portion (3), from a cylindrical shape, from this The upper part of the head (4) & handle spoon Qiu Yi, ^ 5 began to form a circular hole-shaped thickness T series 5 to 3. _, for i. To the periphery to the cavity wall (6) peripheral wall The thickness of the kernel is preferably 10 to 20mm. The material of the thin cover material is polyacrylamide, polyethylene (h), polypropylene (PS), and polyvinyl chloride (vinyl ide). Acrylonitrile-butadiene-stvrenp ^^ aa ^ ^ y) is a thermoplastic resin foam, but in terms of the material's low cost, polystyrene is the best. material. 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 for surface treatment of paint, insert the masking material ⑴ into the insertion part ⑺ before the hole or recess 凹 of the object to be protected, and then apply the masking material ⑴ to the object to be protected, and then apply U Surface treatment. After the surface treatment such as painting is completed, the masking material (1) is removed from the hole or recess (2) of the object to be protected. / By using the masking material (丨) and performing surface treatment such as coating, surface treatment can be prevented from being applied to the hole portion or the recessed portion (2) for protecting the protection target and the peripheral portion thereof. As described above, by providing the cavity portion (6) with the masking material (1), it is possible to reduce the cost of the thermoplastic resin material by 315348 7 1234489. That is, the thermoplastic resin can be reduced by simply providing the cutter of the cavity portion (,), thereby reducing the amount of waste of the masking material (1). In addition, if the expansion ratio of the thermoplastic resin foam is 0-1 to 80 times, moderate elasticity can be obtained, so that it is easy to disassemble and assemble the mask material ⑴. When the expansion ratio of the thermoplastic resin foam is less than 〇0, due to insufficient elasticity, the masking material ("is not easy to be inserted into the concave portion of the protection object. On the other hand, once the expansion ratio of the thermoplastic resin foam exceeds 8 〇times, it will get excessive elasticity, so the masking material ⑴ will easily fall off from the recessed part (2) of the object to be protected. Furthermore, the thickness from the periphery of the head (4) to the peripheral wall of the cavity (6) τ Once it is 5 to 30mm, it can ensure that the masking material (1) has sufficient mechanical strength, and the effect of reducing the material can be fully achieved. From the periphery of the head (4) of the masking material (1) to the cavity The thickness τ of the peripheral wall of the part (6) is less than 5mm. The mechanical strength of the masking material (丨) is insufficient, so the masking material ⑴ is easily damaged. On the other hand, from the periphery of the masking material ⑴ head ⑷ to When the thickness τ of the peripheral wall of the cavity portion (6) exceeds 3 (), the material saving effect becomes smaller. Moreover, once the rib (5) is provided on the periphery of the insertion portion of the mask material (1), the rib (5) 5) Easily elastically deformed so that the rib (5) is closely attached to the hole or recess of the protection object ( 2) The inner peripheral wall, so that the fixing force of the masking material (1) is enhanced for the hole or recess (?) Of the protection object. (Example 2) 315348 8 1234489 is shown in Figures 3 to 5 Other Embodiments: In contrast to the embodiment 1 shown in Figs. 1 and 2, the mask material (11) composed of a thermoplastic resin foam in this embodiment I is composed of a hole or a recess with respect to the object of sigh. (12) The insertion part (13) and the head (1 4) provided on the insertion part (3), wherein a plurality of quadrangular prisms are raised on the periphery of the insertion part (丨 3). The ribs (5) are shaped like cavities (1) (6) on the outer surface of the head (1) and the outer surface of the head (1) through a predetermined thickness T (see Figure 3). The insertion portion (13) is formed into a slightly trapezoidal square column shape with a concave portion (12) corresponding to a trapezoidal square hole shape. The size of the insertion portion (13) is set to be slightly the same as or slightly smaller than the size of the concave portion (12). Furthermore, the width W between the rib (15) and the rib (15) is set larger than the width w of the recess (12). Therefore, the size of the insertion portion (1 3) is set to be slightly the same as Or slightly smaller than the size of the recess (丨 2), and the width between the rib (15) and the rib (15) is set to be greater than the width w of the recess (12), when the masking material is inserted in the recess (12) Without obstructing and easily inserting the masking material (11) in the recessed portion (12), the elastic deformation of the ribs (15) can be firmly fixed. At this time, the periphery of the recessed portion (2) of the protection object is shielded. The head (14) of the material (11) is covered, and even if the size of the insertion part (13) of the masking material (11) is smaller than the recessed part (12) of the protection object, the masking material (1 1) is installed on the recessed part (12). 'During surface treatment such as painting, paint and the like will not adhere to the recessed part (1 2) to be protected. In addition, the head (14) of the masking material (11) is formed into a square pillar shape slightly larger than the insertion portion (13). A square hole-shaped cavity is formed from the outer surface of the head (1 4) ( 16). Furthermore, the thickness of the peripheral wall from the periphery of the head (14) to the cavity portion 315348 9 1234489 is 30 mm 'again, but the optimal thickness T is 10 to 20 mm (see Figs. 4 and 5). As for the material of the masking material i), the same thermoplastic resin foam as in Example i was used. The foaming ratio of the thermoplastic resin foam was also the same as in Example 1. By using the mask material (i) of this embodiment, the same effect as that of the embodiment i can be obtained. In other words, the portion where the cavity portion (i 6) needs to be provided can reduce the thermoplastic resin 'and thereby reduce the amount of waste of the masking material. In addition, since the expansion ratio of the thermoplastic resin foam is 10 to 80 times, moderate elasticity can be obtained, and the masking material (i) can be easily removed and attached. In addition, since the thickness τ from the periphery of the head portion (14) to the peripheral wall of the cavity portion (16) is 5 to 3 Gmm ', the material material 料) can be ensured to have sufficient mechanical strength, and at the same time, material reduction can be fully achieved. Effect. Furthermore, because a rib ⑽ is provided on the periphery of the insertion portion (13) of the cover material ⑴), the elastic deformation of the rib (15) makes the rib (5) tight, so that the hole or recess of the object to be protected The inner peripheral wall of the cymbal can increase the fixing force of the masking material (1) to the hole or recess (12) of the protection target. -In the above, the embodiments of the present invention have been described in accordance with the examples. However, the scope of the present invention is not limited to this, and may be changed or deformed relative to the purpose of the scope of patent application. For example, in addition to this embodiment, as shown in FIG. 6, the 315348 10 1234489 cavity portion ⑷ of the masking material may be set from the top of the head ⑷ to the depth position of the insertion portion (3), and from the cover The thickness T from the periphery of the cover material ⑴ to the peripheral wall of the cavity ⑷ is set to 5 to 30 mm. The child can also penetrate the cavity portion (6) of the masking material ⑴ from the upper part of the head ⑷ to the lower part of the inserting part ⑺, and the thickness T of the peripheral wall of the two-hole portion (6) of the masking material ⑴ can be set to 5 to 30 mm. [Effect of the invention] In the eight books, it is only necessary to provide a cavity portion on the head of the masking material. Erwu = minus: thermoplastic resin, which can also reduce the waste warming of the masking material. In geography, the air pollution or global temperature during the combustion process is moderated.
