  • an intermediate layer may be provided.
  • the intermediate layer may be, for example, a paper, a nonwoven, a foam, film or a sponge that is directly attached to the foam latex rubber layer.
  • the binder may be directly coated on the foam latex rubber, as depicted in FIG. 1, or an intermediate layer may be included. Therefore, either the foam latex rubber or the intermediate layer may be coated with the binder and abrasive particles.

Suitable pre-make coat resins may be applied as solvent or water based formulations or as 100% solids hot melt formulations. Additionally, in some embodiments, the abrasive article may also include an optional size coat extending over the binder and the abrasive particles. Suitable size resins include those mentioned for pre-make coat resins.
  • any suitable abrasive particles may be used with this invention.
  • Suitable abrasive particles include fused aluminum oxide, heat treated aluminum oxide, alumina-based ceramics, silicon carbide, zirconia, alumina-zirconia, garnet, diamond, ceria, cubic boron nitride, ground glass, quartz, titanium diboride, sol gel abrasives and combinations thereof.
  • the abrasive particles can be either shaped (e.g., rod, triangle, or pyramid) or unshaped (i.e., irregular).
  • the term "abrasive particle” encompasses abrasive grains, agglomerates, or multi-grain abrasive granules.
  • the abrasive particles can be deposited onto the binder layer by any conventional technique such as electrostatic coating or drop coating.
  • the intermediate support layer is attached to the foam latex rubber and includes the abrasive surface, which typically will include a coating of the binder and abrasive particles.
  • the intermediate support layer is resiliently deformable (i.e., indentable) and recoverable when squeezed by the thumb and fingers of the user's hand and thus is not likely to slip from the hand even if the fingers are wet or greasy.
  • the intermediate support layer may be somewhat resiliently axially compressible and acts as a cushion between the user's hand and the work surface as the abrasive article is being pushed back and forth to perform the abrading function.
  • the intermediate support layer may be open cell foam, closed cell foam, textured, or planar, natural or synthetic sponge, nonwoven, paper, or film.
  • the intermediate support layer is closed-cell foam.
  • the intermediate support layer may be constructed from high tear strength felted urethane foam.
  • abrasive layer may be a nonwoven.
  • a nonwoven may comprise, for example, an open, lofty nonwoven web of fibers bonded at their points of contact by a resin and/or melt fusion.
  • the nonwoven may also include abrasive particles dispersed throughout the nonwoven or coated on a surface of the nonwoven and secured to the nonwoven web by a binder.
  • Suitable fibers include crimped, staple, synthetic organic fibers such as polyester fibers and nylon fibers, which may be processed and entangled into nonwoven webs by conventional web-forming machines such as that sold under the tradename "Rando Webber” through Rando Machine Company of New York, NY.
  • the resulting web may be heated to bring about melt-bonding of the fibers at their points of contact, and/or may be treated (by spraying, roll-coating, etc.) with a liquid resin which bonds the fibers together.
  • Suitable nonwovens which may serve as the abrasive layer, are available commercially in a variety of thicknesses, densities and abrasive powers under the tradename Scotch-BriteTM from 3M Company of St. Paul, MN.
  • the foam latex rubber layer provides the cleaning surface.
  • the foam latex rubber is effective at removing dust and other small particles from work surface.
  • the foam latex rubber is an open-cell foam.
  • the open cell-foam provides small pockets that are capable of capturing and retaining the dust and other small particles that are encountered during cleaning before and after sanding.
  • a foamed latex rubber suitable for the foam latex rubber layer is sold under the tradename Gonzo available from Quality Rubber Company, a division of Zephyr Manufacturing of Sedalia, MO.
  • the latex rubber material is a natural material that exhibits a natural tackiness without the need for the addition of a secondary adhesive.
  • This natural tackiness is unique and advantageous in use as a cleaning and dusting material.
  • the tackiness assists in picking up and retaining dust and small particles.
  • an additional adhesive may be included for some applications.
  • the latex rubber material may be cleaned using water or other solvents and following cleaning retains a natural tackiness.
  • the attaching layer secures the abrasive layer to the foam latex rubber. As shown in FIGS. 2 and 3 an attaching layer is used to secure the abrasive layer to the foam latex rubber and the intermediate layer of the abrasive layer to the foam latex rubber, respectively.

  • the abrasive surface and the cleaning surface are generally planar and parallel to one another.
  • the present invention is not limited to a single abrasive and a single cleaning surface.
  • the abrasive article may be of a shape or configuration having two or more abrasive surfaces and/or having two or more cleaning surfaces. Additionally, the abrasive surface and cleaning surface need not be planar and may be of other geometric or curved shapes.
  • abrasive surface and cleaning surface are within the scope of the present invention, so long as there is at least one abrasive surface and one cleaning surface.
  • an embedded reinforcing scrim may be included.
  • the scrim may be positioned between the foam latex rubber and the abrasive layer or may be imbedded within an intermediate layer, if included.
  • the abrasive article can be used in a variety of cleaning, sanding, and surface conditioning processes.
  • a particularly useful area for the abrasive article is in the preparation of surfaces, especially wood, plaster, and drywall, and for painting or finishing.
  • the user can grasp the abrasive article by hand with the cleaning surface of the foam latex rubber facing the palm of the user's hand. Then, the abrasive surface of the abrasive layer is available for contact with a surface. The user sands the surface with the abrasive layer and, following sanding, uses the cleaning surface of the foam latex rubber to wipe the dust and debris from the surface being sanded and any surrounding surfaces. Once the foam latex rubber is fully loaded with dust and debris from cleaning, the user can rinse the foam latex rubber with water to remove the dust and debris. When the foam latex rubber layer is cleaned, the abrasive article is available for further use.
