Definitions

  • the present invention relates to a masking member which protects a part of a surface of an article from a surface treatment such as coating, plating, vacuum evaporation, phosphatizing, and the like. More particularly, the present invention relates to a masking member consisting of a sheet having bellows part(s) in selected position(s) of said sheet.
  • a surface treatment is effected on the surface of an article, and if said surface of said article has (a) part(s) on which said surface treatment should not be effected for the reason that another surface treatment is effected on said part(s) after said surface treatment of said surface treatment spoils the appearance of said article and so on, said part(s) of said surface of said article may be covered and protected with said masking member.
  • adhesive tape has been used as a masking member to protect a part of a surface of an article such as a bumper of an automobile and the like. Namely, the adhesive tape is attached to said part of said surface to protect said surface from said surface treatment and after said surface treatment, said adhesive tape is removed from said surface. Said surface may not be affected by said surface treatment since said part of said surface was covered with said adhesive tape during said surface treatment. Nevertheless, adhesive tape as a masking member has faults in that attaching and removing of the adhesive tape to/from said part of said surface take time and have a high labor cost, and further, the adhesive tape attached to said part of said surface is buried in the layer of said surface treatment and it is very difficult to find the end of said buried adhesive tape to remove said adhesive tape. Said faults of adhesive tape may seriously obstruct a mass-production line such as a coating line for automobiles.
  • a reusable paint masking member exhibiting both vertical and horizontal expensibility, is known from US-A-4,759,959.
  • an object of the present invention is to save trouble when the masking member is attached/removed to/from a part to be protected.
  • a masking member consisting of a sheet having bellows part(s) in selected position(s) of said sheet.
  • the invention also provides a method of surface treatment of an article wherein a part of the surface of the article is covered with such a masking, the surface treatment is performed and the masking member is removed.

  • heat resistance, mechanical properties and the like of said masking member are improved by said inorganic filler and further, when a used masking member is burnt in a combustion furnace, a smaller combustion energy is produced so that said combustion furnace will stand long use.
  • 10 to 500 weight parts, desirably 20 to 400 weight parts of said inorganic filler are mixed into said plastics.
  • organic filler such as wood powder, organic, fiber powder, walnut powder, coconut powder, flour, chaff powder and the like may be mixed into said plastics or rubber. Still further, dyestuff, pigment, antioxidant, ultraviolet absorber plasticizer and the like may be mixed into said plastics or rubber.
  • Polyolefin such as polyethylene, polypropylene and the like are desirable plastics for the material of the sheet of the masking member of the present invention since said polyolefin has high solvent resistance and is inexpensive, and of course, polyolefin in which said inorganic filler is mixed is a desirable material for said masking member.
  • Polystyrene foam is also a desirable material for said masking member since said polystyrene foam is light and inexpensive, nevertheless, since said polystyrene foam has a low solvent resistance and a low heat resistance, it is desirable to laminate a suitable plastic or rubber onto said polystyrene foam.
  • Vacuum forming, press molding, casting, extrusion, injection, molding, paper making and the like may be used to produce the masking member of the present invention.
  • the masking member of the present invention does not deform to maintain the shape corresponding with the part of the surface of the article to be protected from surface treatment during the storage, the transportation, handling, and the like, since the masking member is reinforced by said reinforcing rib(s). Therefore the masking member of the present invention can protect completely the part to be protected.

After said masking member (110) is attached said part (211), a surface treatment such as a spray-coating of a paint (400A) is effected on said surface (210) as shown in Fig. 2. After said spray-coating, said masking member (110) is removed from said part (211) and said paint (400A) is not coated on said part (211) since said part (211) has been protected during said coating.
