Definitions

  • the invention relates to an abrasive article which is integrally formed as a form-elastic element and at least partially has a three-dimensional cell structure on a grinding surface, wherein the grinding surface abrasive and at least partially has an open-cell structure.
  • an abrasive body is made WO 02/0 766 78 A1 known.
  • an abrasive element is understood to mean an element that can be used as a grinding device, a scouring device or a cleaning device.
  • the application of the abrasive article depends on the type and structure of the abrasive on the abrasive surface of the abrasive article. Particles are both dirt and abrasive particles to understand. Abrasive particles are created by a abrasive effect of an abrasive article. This results in particles of the material to be abraded surface.
  • normal pad and super pad discs are used, which are used in conjunction with single-disc or multi-disc cleaning machines to clean the floors.
  • the craft and the craftsman mainly cleaning, scouring and abrasive nonwovens are used for grinding, cleaning and de-rusting.
  • filler and paint surfaces also form-elastic sanding sponges are used, which adapt well to profiled surfaces.
  • Surfaces of various materials are processed, for example wood, plastic, metal, non-ferrous metal, stainless steel or coated surfaces, such as painted surfaces.
  • surfaces for example, sandpaper, steel wool, abrasive nonwovens, cleaning sponges, plastic cleaner, Metal and copper cleaners, scourers and stainless steel scourers.
  • the material from which these products are made is also diverse, such as paper, metal and plastic in various physical and chemical embodiments. Each product is suitable and very specific to a particular application.
  • Sandpaper for example, is used to treat wood, metal and paint surfaces.
  • the abrasive effect of the abrasive paper comes about through the grain of the abrasive.
  • Sandpaper as a substrate is flexible, but it can also be easily damaged, for example, by coarse particles or sharp edges.
  • Steel wool is used for general cleaning, smoothing of wood surfaces before and after a glaze and for cleaning solder joints.
  • a disadvantage of steel wool is that in outdoor areas, the steel wool on wood can lead to discoloration. Also, when cleaning solder joints, e.g. with copper pipes, break off small particles of steel wool that remain in the pipe and then prevent proper closing of existing valves. Steel wool is also only partially machine usable.
  • Plastic cleaners are made of plastic and have a good dirt holding capacity. However, they only have a limited scouring and cleaning effect, because The plastic is relatively soft and usually not additionally coated with abrasive.
  • Metal and copper cleaners are more aggressive in scouring than plastic scavengers.
  • the disadvantage here is that they can not be used for scratch-sensitive surfaces therefore.
  • Non-woven fabric cleaners can be produced in many different forms.
  • cleaning and scouring fleeces are laminated to a foam and used as so-called scourers, scouring or cleaning sponges.
  • Scrub and cleaning nonwovens can be coated with an aggressive scouring agent, such as quartz sand, as needed.
  • scouring and cleaning nonwovens are coated with a nonaggressive scouring agent, such as, for example, chalk or talcum.
  • the disadvantage is that the abrasive, scouring or cleaning nonwovens have different fiber blends and nonwoven structures as required.
  • a nonwoven fabric has no cell structure. It consists of a composite of fibers whose structure can be adapted to different requirements. It is thus necessary that for each application, a suitable nonwoven having a different nonwoven structure, stiffness and thickness must be prepared.
  • the invention is based on abrasive sponges, which usually have a closed abrasive surface coated with abrasive.
  • Sanding sponges have the advantage that they by their cellular Structure are form-elastic and can adapt to arbitrarily shaped surfaces very well. However, such abrasive sponges can absorb insufficient dirt or abrasive particles.
  • open-cell foam is used, with abrasives incorporated in the cells.
  • a method of manufacturing an abrasive article is disclosed. Open cell foam is applied to a reinforcement with the abrasive surface and the interior of the open cells provided with abrasives. The foam is passed through heated rollers along with the reinforcement. This achieves a firm bond between the foam and the reinforcement. At the same time, the foam is compressed to the desired thickness.
  • a foam abrasive article and a method of making the abrasive article wherein at least one abrasive surface has an open-celled structure. Abrasives are disposed on the abrasive surface and within the open cells.
  • an abrasive article that includes a flexible plastic body having a plurality of rectangular projections.
  • the projections represent the grinding surface and may have an open-cell structure.
  • the abrasive article and the interior of the cells are provided with an abrasive.
  • WO 02/076678 A1 discloses a flexible abrasive article and a method of making and using the abrasive article.
  • the abrasive article has an open-celled foam with insulation on the abrasive side and a coating of abrasives on top of it.
  • the insulation and the coating are provided with openings which communicate with the interior of the open-cell foam. This is to achieve an air permeability of the abrasive body in the range of 5 to 305 liters per square meter and per second.
  • the invention has for its object to provide a form-elastic grinding body having a good grinding or cleaning action and a capacity for accumulating particles
  • a grid is a two-dimensional structure with open boundary surfaces between the grid frame. If multiple grids are linked together in the third dimension, a three-dimensional structure is created.
  • This three-dimensional structure is just one example of a cell structure.
  • a cell here is a regular or irregular envelope of a cavity, which has exclusively closed boundary surfaces, exclusively open boundary surfaces or partially open and closed boundary surfaces.
  • a cell with only closed boundary surfaces is a closed cell.
  • a cell that has at least one open boundary surface is an open cell. It can pick up and store particles. Such cells are provided on the grinding surface.
  • the abrasive surface should at least partially have such open cells. are adjacent to several open cells, this results in an open-cell structure.
  • the surface partially has an open-cell structure, this means that open cells are arranged in one or more areas of the grinding surface. At other points of the grinding surface these are not present. Instead, there are found, for example, shot cells. If the grinding surface has some or all of an open-cell structure, this has the advantage that particles which accumulate can be absorbed by the open cells present and thus removed from the surface to be processed. This is desirable because they do not adversely affect the abrasive action of the abrasive article and, for example, do not clog it.
  • the element has an air permeability of at least 1500 liters per square meter per second.
  • air permeability is achieved, for example, when particle-passable cells of the abrasive surface communicate with an opposing surface of the abrasive article, which also has particle-passable cells, over a large number of particle-passable cells within the abrasive article.
  • the air permeability depends on the size of the open particle-passable cells, their structure and the pathways between the individual cells.
  • the determination of the air permeability is set out in DIN EN ISO 9237.
  • the predetermined value of 1500 liters per square meter and per second, experience has shown that accumulating particles are sufficiently absorbed by the abrasive body, so as to maintain the grinding effect.
  • Cells of the abrasive surface communicate with cells inside the abrasive article via paths. If a cell has at least two open boundary surfaces, it is particle-passable. It provides a path for particles. This path is not necessarily straightforward. When a particle-passable cell of the abrasive surface is adjacent to an open cell further adjacent the interior of the abrasive article, a path is formed. A particle formed on the surface to be processed can then pass into the particle-passable cell and from there into the adjacent open cell. If this cell is also passable by particles, a path is created which possibly extends further into the interior of the abrasive body. The more cells are connected, the more Paths arise that can pick up and store particles.
  • cells in the interior of the abrasive article which communicate with cells of the abrasive surface have abrasive agents.
  • the cells inside the grinding wheel are open cells that are connected to the open cells of the grinding surface. Via particle-passable cells, there may be paths which either end in a cell or lead to further branching. If the cells in the interior of the abrasive body have abrasives in addition to the sanding surface, the abrasive effect of the abrasive article can be increased.
  • abrasives are in the open cell layer in the interior of the abrasive body, which immediately adjoins the open cell particle-passable cell layer of the abrasive surface.
  • the cell structures Due to the shape-elastic property of the abrasive body, the cell structures can be compressed, so that by a contact pressure during the grinding process internal cells get closer to the grinding surface. Thus, it is possible that the internal abrasives are then effective and despite an open-cell structure of the grinding surface enough abrasives per unit area available.
  • the grinding surface of the abrasive article on a different abrasive than the cells in the interior of the abrasive article can be used simultaneously.
  • the internal abrasives are more or less effective. If, for example, the internal abrasives have a stronger abrasive action than the external abrasives, a strong grinding action is produced with a high contact pressure, while a less abrasive action is produced with a lower contact pressure.
  • a single abrasive body can be used for two grinding functions, for example for a coarse and then for a fine grinding, without the grinding surface must be rearranged or replaced.
  • the abrasive comprises abrasive grains.
  • Abrasive grains are abrasives which are easy to handle in the manufacture of the abrasive article and are available in a variety of forms for different applications. Abrasive grains have a small geometric dimension, so that they can penetrate into the cell structure into the interior of the abrasive body during the production of the abrasive article. This can be done, for example, by impregnating or spraying the abrasive article.
  • the abrasive may be fixed to the cell structure by a resin.
  • the resin may enter the interior of the abrasive article in a flowable form to fix abrasive in the open cells.
  • Resin can also be used to fix the abrasive on the outer grinding surface.
  • the resin may be present, for example, as a polyurethane resin or as an epoxy resin.
  • the abrasive article is impregnated with a scrubbing agent.
  • the abrasive is then present both on the grinding surface and inside the grinding wheel. This may be in addition to abrasives. It is also possible that abrasives are located without abrasive in the interior and on the surface of the abrasive body.
  • the element is a foam.
  • a foam may be elastic in shape and have a cellular structure as provided by the invention.
  • the foam is open-pored and has at least partially open cells.
  • the foam can be made according to the requirements of tough elastic hard or soft and in any thickness as a sheet material, without changing the structure and flexibility. These features does not have a non-woven fabric. Because of these properties, the open-cell foam is an ideal abrasive carrier from which, for example, thin and very flexible abrasive or cleaning wipes can be made, which can be sprayed with abrasive grains, for example as a stainless steel cleaning cloth or for grinding on profiled surfaces can be used. It is possible to produce very mechanically flexible abrasive bodies with foam.
  • a foam allows for better dirt pick-up than, for example, a scrub fleece that is substantially more closed on its surface due to its scrubbing-sprayed batt. Due to the open cell structure can also be the Wash collected dirt out of the grinding wheel again, which is desirable for hygienic reasons.
  • the element is a plastic.
  • Plastic has the advantage that it does not corrode. So it is also possible that the abrasive body can come into contact with moisture, without this being for further grinding operations of disadvantage.
  • the abrasive article can be washed out to rinse any accumulated particles from inside the abrasive article.
  • the abrasive body can be used for wet grinding.
  • a plastic may be form-elastic and at the same time comprise, for example, a honeycomb structure having internal open particle-passable cells and communicating with cells of the abrasive surface. It is also possible that a cell structure is formed in a plastic by foaming. There is then a foam plastic.
  • foams are, for example, polystyrene, styrene copolymers, polyvinyl chloride, polycarbonates, polyolefins, polyurethanes, polyisocyanurates, phenolic resins and polyesters.
  • the element has a compression hardness of at least 2 kilopascals.
  • the compressive strength indicates how far a material can be compressed.
  • DIN EN ISO 3386-1 describes the determination of the compression hardness.
  • a material that has the compression hardness of about 3 kilopascals, for example, is a filter foam made of polyester.
  • the element has a thickness of at least 1 millimeter.
  • the element should have a minimum thickness so that it still has a grinding effect when compressed.
  • a thickness of about 1 millimeter ensures that, despite its cell structure, the element does not dissolve during grinding and remains in the long term as a coherent cell structure.
  • the element is designed as a roll product.
  • Rolled goods can be transported well when rolled up.
  • individual abrasive articles of any geometric shape can be produced from rolls.
  • the element is attachable to a substrate. This can be done for better handling of the abrasive article.
  • the carrier material can likewise be elastically deformable or else less deformable.
  • the element can be laminated onto the carrier material.
  • the abrasive article on surfaces with different effects.
  • Such an abrasive article may be used, for example, with the first abrasive surface for rough grinding and with the second side for fine grinding.
  • the grinding body is designed, for example, as a cuboid, further sides of the grinding body can be available, for example for scrubbing or polishing.
  • the element has differently colored surfaces. Colored surfaces can be used to mark different surfaces. Also, surfaces may be numbered to define, for example, the order of the abrasive surfaces of the abrasive article to be used. Also, letters, words or symbols can be applied to a surface to associate, for example, an investment in an abrasive holder.
  • At least two abrasive bodies are connected to one another via a layer.
  • This layer may, for example, be a barrier layer, so that particles received from the interior of the first abrasive article do not enter the interior of the second abrasive article.
  • the grinding wheels are then not influenced by each other.
  • the layer can also take over the function of a carrier, which assigns the abrasive bodies relative to each other a position and, for example, is at the same time formelastic.
  • FIG. 1 schematically illustrates a two-dimensional closed-cell structure of an abrasive article 1.
  • the abrasive article 1 has abrasive media 3 on its abrasive surface 2.
  • the abrasives 3 act on a surface 4 to be processed.
  • the individual cells 5 of the abrasive body have closed cell walls 6. In Fig. 1, four of these side boundaries 6 of the cells 5 are visible.

  • the cells 5 shown schematically have, as in FIG. 1, a cuboid geometry. In the four visible side walls 6, however, openings 8 are present. If a cell has at least one opening 8, then the cell is referred to here as open-celled.
  • all cells are open cells 9. Open cells 9, which have at least two openings, are particle-passable cells 10. Thus, in Fig. 2, all cells are also particle-passable cells 10.
  • FIG. 3 In comparison, in Fig. 3 there are both closed cells 7 and open cells 9. Some of the open cells are also particle-passable cells 10. These cells 10 are important for the air permeability and penetration depth of the particles into the interior of the abrasive body 1.
  • the arrows in FIG. 3 indicate possible paths for recorded particles.
  • FIG. 4 shows a cuboid grinding body 1 in a three-dimensional representation with the surfaces 11, 12, 13, 14, 15 and 16. If a surface has abrasive material 3, this is an abrasive surface 2. All surfaces 11 to 16 in FIG. 4 are grinding surfaces 2.
  • the grinding surfaces 11a and 15a are shown symbolically with abrasive 3 as partial surfaces of the grinding surfaces 11 and 15.
  • the grinding surfaces 11a and 15a in FIG. 5 result from a section AA according to FIG. 4.
  • the interior of the grinding body 1 in the plane of the cut surface 17 is also visible through this cut.
  • the abrasive body 1 has on its grinding surface 11a, 15a abrasives 3a in the form of abrasive grains with a fine grain.
  • abrasive 3b in the form of abrasive grains with a coarse grain.
  • the grinding wheel 1 thus has on its grinding surfaces 11 to 16 a different abrasive than in the interior of the grinding wheel 1.
  • FIG. 1 A detailed view D of the inner cell structure with the abrasive 3b is shown in FIG.
  • the cells 5 have an irregular cell structure in which the abrasive grains are fixed with a resin.
  • Fig. 6 shows a new state or a cleaned state of the cell structure.
  • particles 18 are still present in the cells in addition to the abrasive 3b from FIG. 6. These particles 18 originate from the grinding surface 2 and pass through particle-passable cells 10 into the interior of the grinding wheel 1. They are held there until they are for example washed out of the grinding wheel 1 in a cleaning process, so that then the interior of the grinding wheel 1 again assumes the state shown in Fig. 6.
  • FIGS. 8a, 8b and 8c show the grinding wheel 1 from FIG. 4 cut as in FIG. 5, but here in a two-dimensional sectional view AA.
  • FIG. 8 a shows the grinding body 1 on the surface 4 to be processed.
  • the grinding body 1 from FIG. 8 a is subjected to a planar force. This is indicated by a broad arrow 19 for a large force in Fig. 8b and by a narrow arrow 20 for a lesser force in Fig. 8c.
  • the two-dimensional force causes the original height of the grinding wheel to be reduced. For a large force according to FIG. 8b, this height reduction is greater than for the smaller force according to FIG. 8c.
  • the abrasive body 1 is loaded with a large force surface, as shown in Fig. 8b, so get through the compression of the cell structure, the abrasive 3b of the internal cells to the grinding surface 2.
  • the grinding surface 2 now has simultaneously abrasive 3b from the inner region of the abrasive body 1 and abrasive 3a.
  • a force is necessary, which is referred to here as "large”. Since coarse abrasive grains are generally geometrically larger than fine grain abrasive grains 3a, the coarse abrasive grains 3b from the interior in Fig. 8b appear more effective than the fine grain abrasive grains 3a. In this case, a rough grinding or cleaning takes place.
  • FIG. 8b If the force of FIG. 8b is changed, the coarse-grained abrasive grains 3b with their internal cells 5 retract from the surface to be processed, as indicated in FIG. 8c. There is only a small area force, symbolically represented by the narrow arrows 20. This small force is not sufficient to bring the internal abrasives 3b to the grinding surface 2. Compared to the state of Fig. 8a, the abrasive article is still compressed, but so small that the internal abrasive 3b no longer be in contact with the surface to be machined 4. In this state, only the outer abrasives 3a of the grinding surface act and cause a finer grind, for example, by their finer grain size. For more accurate metering of the two planar forces in FIGS. 8b and 8c, it is also possible to install the grinding wheel 1 in a grinding wheel holder of a grinding machine which creates a planar force for the two machining states according to FIGS. 8b and 8c.
  • the abrasive body 1 has only one type of abrasive 3 both on its grinding surface 2 and in the interior of the grinding body 1.

  • the Velcro velor layer 21 serves as a carrier material and gives the foam plastic a dimensional stability. However, due to the velcro velor layer 21, the foam plastic is not as flexible deformable as it would be without the Velcro velor layer 21.
  • the Velcro velor layer can serve as a fastening device by cooperating with a further Velcro layer and so fixes the grinding wheel 1, for example, in a grinding tool holder.
  • This abrasive article holder can be both part of a grinding machine or a device for manual processing.

  • FIG. 11 shows a further embodiment in which two abrasive bodies 1 are connected via an intermediate layer 25.
  • the layer 25 serves in this Example as a barrier layer. It establishes a barrier for received particles 18 inside the grinding wheels 1.
