Definitions

• the present invention relates to a masking material used for protecting a part of the surface of a member from surface treatment when the member is subjected to surface treatment such as painting or plating.
• paint such as polyvinyl chloride sol or tar urethane is applied to the back of the car floor, but many holes such as bolt holes, cable holes, drain holes, and shaft holes are provided on the back of the floor. Or where there is a place to attach parts such as brackets.
• the coating is performed before the coating. Each part is covered with a masking material.
• the masking material (1) is adhered to the portion (5) to be protected of the member (4.) via the adhesive layer (3) as shown in FIG. 11, and is separated from the portion (5) after coating. You.
• the masking material (1.) is applied to the portion (5) of the member (4) after coating. )
• the masking material (1) is not easily removed because it is hindered by the coating film (6).

• the masking material (11) includes a plate-shaped main body (12) and an adhesive formed on one surface of the plate-shaped main body (12).
• the Step (12) A is formed on the periphery of one surface of the plate-shaped main body (12).
• the step (12) A preferably has a width W of at least one thigh and a height h of 0.2 to 10 ran, preferably 0.5 to 5 ram as shown in FIG.
• the masking material (11) of the present invention is made of a plastic such as polystyrene, polyethylene, polypropylene, polyvinyl chloride, polyurethane, melamine resin, urea resin, or phenol resin, or the above-mentioned plastics such as calcium carbonate and nylon.
• a plastic such as polystyrene, polyethylene, polypropylene, polyvinyl chloride, polyurethane, melamine resin, urea resin, or phenol resin, or the above-mentioned plastics such as calcium carbonate and nylon.
• Reinforced plastics mixed with inorganic fillers such as benzene, bentonite, etc., or rubbers such as synthetic rubbers such as the above-mentioned plastics, styrene-butadiene rubber, acrylonitrile-butadiene rubber, and natural rubbers , Wood fiber, synthetic fiber, natural fiber, inorganic fiber, etc., a fiber molded product formed by binding with a binder, wood, paper, waste paper, corrugated cardboard, metal or a composite of two or more materials selected from the above materials Materials or laminates are used as materials.
• the masking material (1 1) is adhered to the portion (15) to be protected of the member (4) via an adhesive layer (3), and is coated with a paint such as a polyvinyl chloride sol. Etc. Surface treatment is performed.
• the surface treatment film (16) is formed by such a surface treatment, and the surface treatment film (6) is cut at the periphery of the masking material (11) by the step (12) of the masking material (11).
• the width W of the step (12) ⁇ of the masking material C11) is 1 mm or less and the height is 0.2 mm or less
• the surface treatment film 16) is cut by the step (12) A. Hateful.
• the surface treatment film (16) also penetrates into the step (12) A, so that it is difficult to cut off at the periphery of the masking material (1).
• the masking material (11) is removed from the protected portion (15) of the member (14) after the surface treatment, but the masking material (11) is made of a heat-shrinkable material such as a plastic foam.
• the masking material [11] is heated to a heat shrinkage temperature or higher to cause heat shrinkage.
• the heat shrinkable material (11) A of the masking material is automatically separated and dropped from the location (15) without being hindered by the surface treatment film (16). Further, the masking material (11) may be separated from the location (15) by piercing a hook (7) as shown in FIG.
• the masking material (11) of this embodiment may be arranged vertically and horizontally through a number of folding grooves (18) to be integrated into an aggregate (10). In use, one masking material (11) is cut from the assembly (10) along the folding groove (18). Also, depending on the shape and size of the part (14) to be protected ⁇ 5), several masking materials ⁇ 1) such as 1X2, 2X2, 1x3, 2X3, 33, etc. ⁇ 1) may be integrated. You may break it off.
• FIG. 7 shows another embodiment of the present invention.
• a concave portion (12) B is provided in the center of the surface of the masking material (11) on the side of the adhesive layer (13). Therefore, in the masking material (11), the area on the side of the adhesive layer (13) is reduced by the size of the concave portion (12), and the adhesive strength of the masking material (11) to the protected area (15) is reduced accordingly. As a result, the masking material (11) is easily separated from the location (15).
• FIG. 8 shows still another embodiment of the present invention.
• a crater-shaped recess (12) C is provided at the center of the surface of the masking material (11) opposite to the adhesive layer 13).
• a finger is engaged with the recess 12) C.
• the concave portion (12) C makes it easy to bend and deform, and the member (: 14) is protected from the portion (: 15) to be protected. Separation becomes easier.
