[Prior art] As shown in Fig. 7 and Fig. 8, a masking material (lp) composed of a foam of a thermoplastic resin such as polystyrene is generally provided. A solid masking material (1P) composed of an insertion portion (3p) of a hole portion or a recessed portion (2p) and a head portion (4p) provided at the root end of the insertion portion (3P). (Refer to Patent Document 1). [Patent Document 1] Patent Document 1: Japanese Patent Laid-Open No. 62-1 99 173 (pages 4 to 7, page i) Θ [Contents of the Invention] (Problems to be Solved by the Invention) But 疋In the conventional masking material (lp), the foam of the thermoplastic resin of the material of the masking material (ip) has low heat resistance, and the heating of the masking material (ip) with rhenium will cause the masking material (丨 p) There is a lot of deformation and shrinkage. It is difficult to recycle the masking material. For this reason, it is not uncommon for & once-used masking material (1P) to be recycled, but to be discarded. However, when the masking material (1 p) is discarded, it is almost burned. The treatment is performed, and therefore, the gas discharged during the combustion treatment has a problem that it is one of the causes of atmospheric pollution, earth, and warming. (Solution to solve the problem) 315348 5 200418576 The present invention provides a method for solving the above-mentioned conventional problems, and provides a covering and a dry material (1, 1 1) composed of a thermoplastic resin foam body, and the subphase is hung on the companion protection. The target hole or recess (2, ⑺ 为 右 # 1 ^ 1 丨 2) has an insertion portion (3, 13), and a cavity portion (6, 16) is formed from the periphery through a predetermined thickness. The expansion ratio of the thermoplastic resin foam is ⑼ times, and the thickness T of the peripheral wall surrounding the cavity portion: 6, 16) is preferably 5 to 30 mm. The outer periphery of the Erguangxuan insertion portion (3, 13) is preferably provided with a plurality of ribs (5, 15). [Action] The mask material ⑴t 'used in the present invention can save the thermoplastic resin material by providing the cavity portion (6)' with the mask material ⑴. That is, because the cavity only needs to be provided in the cavity (6), Qiu Ba, 4, and '丨 ()' s mouth P knife can reduce the thermoplastic resin, thereby reducing the waste of the masking material (1). Processing capacity. [Embodiment] [Embodiment 1] The present invention will be described with reference to the embodiments shown in Fig. 1 and Fig. 2. … The masking material 组成 composed of thermoplastic resin foam is composed of the insertion part (3) opposite to the hole or recess (2, 2) of the protection object and the head () provided at the root end of the insertion part =) 4), wherein the periphery of the insertion part (3) ^ has a plurality of square columnar ribs (5), and is formed from the top of the head (4) from the periphery through a predetermined thickness τ Cavity section (6) (see Fig. 1). 〇 The inserting part (3) of the masking material (1) is formed corresponding to the circular hole-shaped recess (2), and the conical shape, the diameter D of the tip of the inserting part (3) is set to be slightly smaller than that of the recess (2). For straight eucalyptus d, the diameter D2 of the root end of the insertion portion (3) is set to be slightly larger than the diameter of the recess 6 (315348 200418576) (dCDfdcD,). According to Zhao avoiding i4, -'..., ^ The inserting part (3) of Zhuo Caike (1) is formed in this net-like shape. When the inverse mask is inserted into the recess, the masking material is not placed. It is detached from the recess (2) and is firmly fixed by its elastic rebound force. The head (4) of the masking material (1) is formed to be slightly larger than the insertion portion ⑺: a two-diameter cylindrical shape, and a circular hole-shaped Gaba 邛 (6) is formed from the top of the head ⑷. The thickness from the periphery of the head ridge to the peripheral wall of the cavity ridge is 5 to 30 mm, but preferably 10 to 20 positions. ^ As the material of the masking material (1), polypropylene (pp), polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC, Polly (vinyl chl〇dde) )), Thermoplastic resin foams such as acrylonitrile_butadiene_styrene resin (abs, aetylOnmile_butadiene_styrene), but polystyrene is the best material in terms of the low cost of the material. The foaming 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 (1) for surface treatment such as painting, insert the masking material (3) into the hole or recess (2) of the thin object before inserting the masking material (3), and then "inch 4" The target women's dressing material (1) is subjected to surface treatment such as painting. After the surface treatment such as painting is completed, the masking material (丨) is removed from the hole or recess (2) of the protection target. By using the masking material (1) and performing surface treatment such as coating, surface treatment can be prevented from being applied to the holes or recesses (2) that protect the object to be protected and the peripheral portions thereof. As described above, by providing the cavity portion with the mask material, it is possible to achieve savings in thermoplastic resin materials. That is, the thermoplastic resin can be reduced by simply providing the cavity portion (6), and the amount of waste of the masking material (1) can be reduced. In addition, if the expansion ratio of the thermoplastic resin foam is from 0 to 80 times, moderate elasticity is obtained on month b. Therefore, it is easy to disassemble and assemble the masking material (丨). When the expansion ratio of the thermoplastic resin foam is less than i 0 times, due to insufficient elasticity, the masking material (1) is difficult to be inserted into the recessed portion (2) of the protection target. When the bubble ratio exceeds 80 times, excessive elasticity is known, so the masking material ⑴ is likely to fall off the concave portion (2) of the protection target. In addition, once the thickness τ from the periphery of the head (4) to the peripheral wall of the cavity (6) is 5 to 30 mm, it is possible to ensure that the masking material (1) has sufficient mechanical strength and can also obtain sufficient material Reduced effect. When the thickness D from the periphery of the head (4) of the mask material (1) to the peripheral wall of the empty six (6) is less than 5 mm, the mechanical strength of the mask material (1) is insufficient, so the mask material ⑴ is easily damaged. On the other hand, when the thickness τ from the periphery of the mask material ⑴ head ⑷ to the peripheral wall of the cavity portion (6) exceeds 30 °, the material saving effect becomes small. Furthermore, once ribs are provided on the periphery of the insertion portion (3) of the masking material (1), the ribs of the mouth are easily deformed elastically so that the ribs (5) closely fit the inside of the holes or recesses of the object to be protected. Peripheral wall, so the hole $ of the protection object can enhance the fixing force of the masking material (1). (Embodiment 2) 315348 8 200418576 FIGS. 3 to 5 show other embodiments. Compared with the embodiment shown in Figs. 1 and 2, the masking material (1 丨) composed of a thermoplastic resin foam in this embodiment is formed by a hole or a recess (1 2) ) And an insertion part (丨 3), and a head (1 4) provided at the root of the insertion part (1 3), wherein the periphery α of the insertion part (丨 3) has a plurality of convex four A prismatic rib (丨 5) forms a cavity portion (16) on the outer surface of the head portion (14) from the periphery through a predetermined thickness T (see FIG. 3). The insertion part (13) of the masking material (11) is formed into a trapezoidal square column shape with a concave part (12) corresponding to a trapezoidal square hole shape, and the size of the insertion part (3) is set to be slightly the same as or slightly It is smaller than the size of the recess (12), and the width W between the rib (15) and the rib (15) is set to be larger than the width w of the recess (12). So by inserting. The size of 卩 (1 3) is set to be slightly the same as or slightly smaller than the size of the recess (1 2) and the width W 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 (丨 丨) is inserted into the recess (丨 2), it is not obstructed and is easily inserted into the recess (1 2) while the masking material (1 1) is inserted through the rib (丨 5). The elastic deformation can be firmly fixed. At this time, the periphery of the recessed portion (丨 2) of the protection object is covered by the head (14) of the masking material (11). After the masking material (1 1) is installed in the recessed portion (丨 2), paint or the like will not adhere to the recessed portion (1 2) of the object to be protected during surface treatment such as painting. 1) The head (1 4) is formed into a square pillar shape slightly larger than the insertion portion (丨 3). A square hole-shaped cavity portion (1 6) is formed from the outer surface of the head (丨 4). Furthermore, the thickness from the periphery of the head (丨 4) to the peripheral wall of the cavity (丨 6) is 9 315348 200418576 10 to 20mm (refer to the T-th system 5 to 30mm 'but the optimal thickness D-series 4 and 5 Figure) For the thick material ^ yi rn X material of the masking material (1 1), it is a foam using the same thermoplastic resin as in Example 丨. Xijian Lake # 此 _ ^ M ..., earthy tree The foaming ratio of the foam on the month and day is also the same as that of Example 1. Using the masking material of this example, r Η, f (11), the same as that of Example i Make That is, only by providing the cavity portion (16), the thermoplastic resin can be reduced, thereby reducing the amount of waste of the masking material. Also, the foaming of the thermoplastic resin foam can be reduced. The magnification is 10 to 80 times, so you can get moderate flexibility, and it is easy to remove and install the masking material 枓 (11). Also, because The thickness of the T series from the periphery of the head (14) to the peripheral wall of the cavity (16) is 5 to 3 Gmm, so the masking material can be ensured. effect. Furthermore, since the inserting part 03) of the cover material ⑴) is externally provided with a rib (15), the elastic deformation of the rib (15) causes the rib (15) to closely contact the hole portion of the protection object or The inner peripheral wall of the concave portion (12) can enhance the fixing force of the masking material (丨) to the hole portion or the concave portion (12) of the protection object. As mentioned above, although the embodiment of this invention was described based on the Example, the scope of this invention is not limited to this, It may change and deform | transform with respect to the objective described in the patent application range. • The mask 315348 10 200418576 can also be provided from the top of the part (4) to the depth of the insertion part (3) from the top of the part (4) as shown in FIG. 6 except for this embodiment. 6), the degree T is set to be from 5 to 30 mm thick from the periphery of the mask material (1) to the peripheral wall of the cavity portion (6). The cover star can be from the upper part of the head to the lower part of the insertion part (3). The cavity part ⑷ where the hole part (6) and two ⑴ are provided is penetrated, and from the periphery of the mask material ⑴ to the empty part. (6) The thickness τ of the peripheral wall is set to 5 to 30 mm.
