Description

[Technical Field]

[0001] The present disclosure relates to a masking member and a surface treatment method. [Background technology]

[0002] Conventionally, a masking member that is placed on a surface to be treated that is to be coated with a surface treatment agent has been known (Patent Document 1). This masking member includes a masking material that covers the surface to be treated and a marking jig that protrudes from the upper surface of the masking material and marks the position of the masking material after surface treatment. When the surface to be treated is covered with the masking material and the surface treatment agent is applied, the marking jig protrudes from the upper surface of the layer of the surface treatment agent. Therefore, a worker can remove the masking material by using the marking jig that protrudes from the surface treatment agent as a guide. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-297302 Summary of the Invention [Problem to be solved by the invention]

[0004] Here, the above-mentioned masking material is placed on the surface to be treated with the marking jig penetrating the center of the masking material. This causes a problem in that the surface treatment agent penetrates into the area to be masked through the through-holes of the masking material. The area to be masked has separate coating specifications. If the surface treatment agent penetrates into the area to be masked, it must be removed again, resulting in a re-extraction process.

[0005] An object of the present invention is to provide a masking member and a surface treatment method that can suppress the penetration of a surface treatment agent. [Means for solving the problem]

[0006] The masking member according to the present invention is a masking member that is placed on a surface to be treated that is to be painted with a surface treatment agent, and comprises a masking material that covers the surface to be treated, and an indicator jig that protrudes from the upper surface of the masking material and indicates the position of the masking member after surface treatment, and the masking material has an infiltration suppression means that prevents the surface treatment agent from infiltrating into the area to be masked.

[0007] This masking member includes a masking material that covers the surface to be treated and a marking jig that protrudes from the upper surface of the masking material and marks the position of the masking member after surface treatment. Therefore, when the surface to be treated is covered with the masking material and a surface treatment agent is applied, the marking jig protrudes from the upper surface of the layer of surface treatment agent. Therefore, a worker can remove the masking material using the marking jig that protrudes from the surface treatment agent as a guide. Here, the masking material has a penetration suppression means that prevents the surface treatment agent from penetrating the area to be masked. Therefore, penetration of the surface treatment agent into the area to be masked can be suppressed.

[0008] The infiltration suppression means may be configured by providing a marking jig on the masking material without penetrating the masking material. Thus, the infiltration suppression means can suppress the infiltration of the surface treatment agent by the masking material in a state in which no through-holes for inserting the marking jig are formed. Therefore, it is possible to suppress the infiltration of the surface treatment agent into the area to be masked through the through-holes of the masking material.

[0009] The permeation suppression means may include a surface treatment agent permeation suppression sheet provided between the area to be masked and the masking material. In this case, the surface treatment agent permeation suppression sheet can suppress the permeation of the surface treatment agent into the area to be masked.

[0010] The marking jig may be fixed to the upper surface of the masking material. With this configuration, the marking jig can be attached to the masking material without forming a through hole in the masking material.

[0011] At least the upper surface of the masking material may be formed of a resin film material, which can prevent the surface treatment agent applied to the upper surface of the masking material from penetrating to the lower surface side.

[0012] The masking material may have a protective material covering the adhesive surface on the lower surface side, which can be peeled off from the outer edge of the masking material while leaving the central region of the masking material. In this case, removing the protective material from the outer edge of the masking material can expose the adhesive surface of the outer edge of the masking material. Therefore, the masking material is attached to the surface to be treated by the adhesive surface of the outer edge. On the other hand, the central region of the masking material is not attached to the surface to be treated because the adhesive surface is protected by the protective material. Therefore, the masking material can be easily removed from the surface to be treated.

[0013] The surface treatment method according to the present invention is a surface treatment method in which a surface to be treated is painted with a surface treatment agent using a masking member that includes a masking material and a marking jig that protrudes from the upper surface of the masking material, and includes the steps of covering the surface to be treated with the masking material, applying the surface treatment agent to the surface to be treated, and removing the masking material from the surface to be treated using the marking jig that protrudes from the layer of applied surface treatment agent as a marker, wherein the marking jig is attached to the masking material in a state where it does not penetrate the masking material.

[0014] According to the surface treatment method of the present invention, it is possible to obtain the same functions and effects as those of the above-mentioned masking member. [Effects of the Invention]

[0015] According to the present disclosure, it is possible to provide a masking member and a surface treatment method that can suppress the penetration of a surface treatment agent. [Brief explanation of the drawings]

[Figure 3] This is a plan view of the upper deck. [Figure 4] 1A to 1C are schematic cross-sectional views for explaining the procedure of a surface treatment method. [Figure 5] 1A to 1C are schematic cross-sectional views for explaining the procedure of a surface treatment method. [Figure 6] FIG. 10 is a schematic cross-sectional view of a masking member according to a modified example. DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, embodiments of the masking member and surface treatment method according to the present disclosure will be described with reference to the drawings. In the description of the drawings, identical or corresponding elements are designated by the same reference numerals, and duplicate explanations will be omitted as appropriate. In addition, the drawings may be partially simplified or exaggerated to facilitate understanding, and the dimensional ratios and the like are not limited to those shown in the drawings.

[0018] FIG. 1 is a plan view of a masking member 1 according to this embodiment. FIG. 2 is a schematic cross-sectional view of the masking member 1 and a target area 21 to be masked. The masking member 1 is used when performing a wide range of surface treatments, such as painting the walls of a building or applying non-skid coating to the upper deck of a ship. The masking member 1 is placed on a portion of the surface to be treated that is not to be surface treated. After the surface treatment, the masking member 1 can be removed from the surface to be treated to remove the surface treatment agent from the target area to be masked. In this embodiment, an example will be described in which the upper surface of the upper deck 25 of a ship is the target surface 20, and a fastening portion 26 formed on the upper deck 25 is the target area 21 to be masked.

[0019] First, the area 21 to be masked will be described. The upper deck 25 of a ship is entirely coated with a surface treatment agent 30 (see FIG. 5), such as a non-skid agent. In ships on which aircraft are carried, lashing sections 26 for lashing the ropes are formed on the upper surface of the upper deck 25 in order to fasten lashing ropes for lashing the aircraft. The lashing sections 26 have bars 23 for lashing the ropes and recesses 22. For example, as shown in FIG. 3, a plurality of lashing sections 26 are formed on the upper deck 25 at intervals from one another. The masking member 1 is installed on the upper deck 25 so as to cover each lashing section 26.

[0020] As shown in FIGS. 1 and 2, the masking member 1 includes a masking material 2 and a marking jig 3.

[0021] The masking material 2 is a member that covers the treatment surface 20 in the area 21 to be masked. The masking material 2 is a sheet-like member that is circular when viewed from above (see FIG. 1). At least the upper surface 4 of the masking material 2 is formed from a resin film material. The film material is a sheet made of resin such as vinyl or general-purpose plastic. Unlike fiber materials, the film material is a resin material that is stretched into a sheet shape without gaps, and can therefore block the penetration of the surface treatment agent 30. The thickness of the masking material 2 is not particularly limited as long as it prevents the permeation of the surface treatment agent 30 and is easy to handle, but may be set to, for example, 0.5 to 4 mm. The diameter of the masking material 2 is set to a dimension that can cover the entire fastening portion 26, which is the area 21 to be masked.

[0022] The entire masking material 2 may be made of a film material, or only the upper surface 4 of the masking material 2 may be made of a film material. For example, a vinyl coating may be applied to the upper surface of the base material of the masking material 2, so that the film material is formed only on the upper surface 4.

[0023] The masking material 2 has a protective material 6 that covers the adhesive surface 2b on the lower side. An adhesive layer is formed on the lower surface of the masking material 2. Therefore, the lower surface of the masking material 2 becomes the adhesive surface 2b. Materials such as paper or general-purpose plastic are used for the protective material 6. The protective material 6 covers the entire adhesive surface 2b of the masking material 2. The protective material 6 can be peeled off from the outer edge of the masking material 2 while leaving the central region of the masking material 2. Specifically, the outer edge 6a of the protective material 6 can be peeled off independently from the central main body portion 6b via a slit CL.

[0024] The marking jig 3 is a member that protrudes from the upper surface 2a of the masking material 2 and marks the position of the masking material 1 after surface treatment. The marking jig 3 has a base 11 and a pole 12. The base 11 is a member that extends in a circular plate shape. The pole 12 is a member that protrudes upward from the upper surface of the base 11. The pole 12 has a length that protrudes upward from the upper surface of the layer of surface treatment agent 30 after surface treatment. For example, depending on the applied thickness of the surface treatment agent 30, the length that protrudes from the upper surface is approximately 30 to 40 mm. The thickness of the base 11 is 2 mm. The marking jig 3 is provided at the center position of the masking material 2.

[0025] The marking jig 3 is provided on the masking material 2 without penetrating the masking material 2. Therefore, no through-hole or the like for passing the marking jig 3 is formed in the central position of the masking material 2 where the marking jig 3 is provided. Specifically, the marking jig 3 is fixed to the upper surface 2a of the masking material 2. The marking jig 3 is attached by attaching the lower surface of the base 11 to the upper surface 2a of the masking material 2.

[0026] The masking material 2 has an infiltration suppression means 50 to prevent the surface treatment agent 30 from infiltrating the masking target area 21. In this embodiment, the infiltration suppression means 50 is configured by providing the marking jig 3 on the masking material 2 in a state where it does not penetrate the masking material 2. In other words, the structure of the masking material 2, which does not have a through-hole, functions as the infiltration suppression means 50.

[0027] Next, a surface treatment method using the masking member 1 will be described. First, the outer edge 6a of the protective material 6 is peeled off from the masking material 2 to expose the adhesive surface 2b of the outer edge of the masking material 2. Next, as shown in FIG. 4(a), a step is carried out in which the masking material 2 covers the treatment surface 20 around the target masking area 21, and the adhesive surface 2b of the outer edge is attached to the treatment surface 20.

[0028] Next, as shown in Figure 4(b), a process is carried out in which a surface treatment agent 30 is applied to the surface 20 to be treated. The surface treatment agent 30 is a non-skid paint containing an anti-slip substance, and is applied by an automatic painting device to the wide upper surface of the upper deck 25. At this time, the marking jig 3 is once deformed and collapsed as the automatic painting device advances, but due to its elasticity, it breaks through the layer of the applied surface treatment agent 30, protrudes above the upper surface, and returns to an upright state.

[0029] Next, after the application of the surface treatment agent 30 is completed and the surface treatment agent 30 has dried, a step is carried out in which the masking material 2 is removed from the surface to be treated 20 using the marking jig 3 protruding from the layer of the applied surface treatment agent 30 as a mark, as shown in Figure 5. At this time, the marking jig 3 marks the area where the masking material 2 has been applied, so the worker can easily remove the masking material 2 by using the marking jig 3 as a mark. When the masking material 2 is removed, the surface treatment agent 30 applied on the masking material 2 is also removed from the surface to be treated 20.

[0030] Next, the functions and effects of the masking member 1 and the surface treatment method according to this embodiment will be described.

[0031] The masking member 1 according to this embodiment includes a masking material 2 that covers the surface 20 to be treated, and a marking jig 3 that protrudes from the upper surface 2a of the masking material 2 and marks the position of the masking member 1 after surface treatment. Therefore, when the surface 20 to be treated is covered with the masking material 2 and a surface treatment agent 30 is applied, the marking jig 3 protrudes from the upper surface of the layer of surface treatment agent 30. Therefore, a worker can remove the masking material 2 by using the marking jig 3 protruding from the surface treatment agent 30 as a guide. The masking material 2 includes a permeation suppression means 50 that prevents the surface treatment agent 30 from permeating the area 21 to be masked. Therefore, permeation of the surface treatment agent 30 into the area 21 to be masked can be suppressed.

[0032] The infiltration suppression means 50 may be configured by providing the marking jig 3 on the masking material 2 in a state where it does not penetrate the masking material 2. Therefore, the infiltration suppression means 50 can suppress the infiltration of the surface treatment agent 30 by the masking material 2 in a state where no through-holes for inserting the marking jig 3 are formed. Therefore, it is possible to suppress the infiltration of the surface treatment agent 30 into the area 21 to be masked through the through-holes of the masking material 2.

[0033] The marking jig 3 is attached to the masking material 2 without penetrating the masking material 2. Therefore, no through-hole for inserting the marking jig 3 is formed in the masking material 2. This prevents the surface treatment agent 30 from penetrating into the area 21 to be masked through the through-hole of the masking material 2.

[0034] The marking jig 3 may be fixed to the upper surface 4 of the masking material 2. With this configuration, the marking jig 3 can be provided on the masking material 2 without forming a through-hole in the masking material 2.

[0035] At least the upper surface 4 of the masking material 2 may be formed of a resin film material. In this case, it is possible to prevent the surface treatment agent 30 applied to the upper surface 4 of the masking material 2 from permeating to the lower surface side.

[0036] The adhesive surface 2b on the lower side of the masking material 2 is covered with a protective material 6, and the protective material 6 may be peelable from the outer edge of the masking material 2 while leaving the central region of the masking material 2. In this case, removing the protective material 6 from the outer edge of the masking material 2 can expose the adhesive surface 2b on the outer edge of the masking material 2. Therefore, the masking material 2 is attached to the surface 20 to be treated by the adhesive surface 2b on the outer edge. On the other hand, the central region of the masking material 2 is not attached to the surface 20 to be treated because the adhesive surface 2b is protected by the protective material 6. Therefore, the masking material 2 can be easily removed from the surface 20 to be treated.

[0037] The surface treatment method according to this embodiment is a surface treatment method in which a surface to be treated 20 is painted with a surface treatment agent 30 using a masking member 1 including a masking material 2 and a marking jig 3 protruding from an upper surface 4 of the masking material 2. The surface treatment method includes a step of covering the surface to be treated 20 with the masking material 2, and a step of removing the masking material 2 from the surface to be treated 20 using the marking jig 3 protruding from the layer of the applied surface treatment agent 30 as a mark, and the masking material 2 is attached to the masking material 2 by a permeation suppression means 50. The marking jig 3, which suppresses permeation of the surface treatment agent 30 into the masked area 21, is attached to the masking material 2 in a state where it does not penetrate the masking material 2.

[0038] According to the surface treatment method of this embodiment, it is possible to obtain the same functions and effects as those of the masking member 1 described above.

[0039] The present invention is not limited to the above-described embodiments.

[0040] For example, the permeation suppression means 50 may include a surface treatment agent permeation suppression sheet 40 provided between the masking target area 21 and the masking material 2. In this case, the surface treatment agent permeation suppression sheet 40 can suppress the permeation of the surface treatment agent 30 into the masking target area 21. For example, as shown in FIG. 6 , a plastic film or a protective sheet serving as the surface treatment agent permeation suppression sheet 40 is sandwiched between the protective material 6 and the bar material 23 (masking target area 21). This makes it possible to prevent the surface treatment agent 30 from permeating into the bar material 23 and the depression 22, even if the marking jig 3 penetrates the masking material 2.

[0041] For example, in the above embodiment, an example was described in which a masking member was placed on the fastening portion when applying a non-skid agent to the upper deck. However, there is no particular limitation on the object for which the masking member is used. For example, when applying a surface treatment agent to the wall surface or roof of a building, a masking member may be placed to mask the location where a photovoltaic power generation device or a solar heat utilization device is to be installed.

[0042] In the above-described embodiment, the masking material has a circular shape, but the shape of the masking material is not particularly limited, and the shape may be changed appropriately depending on the shape of the area to be masked. [Explanation of symbols]
