Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention generally relates to abrasive articles. [Prior Art] In general, a kappa cloth abrasive. The mouthpiece contains a polishing layer that is fixed to the main surface of the back. The abrasive layer typically includes abrasive particles and fixed abrasive particles to the binder. A general purpose coated abrasive article has an abrasive layer comprising a make layer, a size layer, and abrasive particles. In the manufacture of the coated abrasive article, a preparation layer comprising a first binder precursor is applied to the major surface of the backing. The abrasive particles are then at least partially embedded in the preparation layer (e. g., using an electrostatic coating process), and the first binder precursor is cured (i.e., crosslinked) to immobilize the particles in the preparation layer. A slurry layer comprising a second binder precursor is then applied over the preparation layer and the abrasive particles, which in turn cures the binder precursor. Another general purpose coated abrasive article comprises an abrasive layer fixed to the major surface of the backing 'where the abrasive layer is applied to the major surface of the backing by applying a slurry comprising a binder precursor and abrasive particles and then curing the bond Precursor to produce. Typically, the slurry is shaped prior to curing to form a plurality of shaped abrasive composites that are attached to the backing. Non-woven abrasive products are typically made by coating abrasive coated precursors onto non-woven webs (e.g., non-woven elastic apertured webs) and curing abrasive coated precursors. This type of non-woven abrasive that is familiar is sold under the trademark "SCOTCH-BRITE" by 3M Company, St. Paul, Minnesota. 157738.doc 201219155 During the manual repair of paint surfaces (such as the paintwork of car bodies), hand-applied abrasive sheets (such as sandpaper) or elastic amine phthalate sponge abrasive sheets (sanding sp) are usually used in practice. 〇nge). Hand-held coated abrasive sheets are typically used by folding abrasive sheets and using a linear motion to create a grinding action. Typical workpiece surfaces include wood, fillers (fiUer), primers, and/or other hard coatings. Such abrading mode typically produces a non-uniform pressure due to contact with the fingers and/or palms, resulting in a relatively aggressive and/or uneven wipe pattern. In addition, many hand-held coated abrasive sheets are flat and relatively stiff, making them difficult to handle, especially when grinding curved or irregular shaped surfaces. SUMMARY OF THE INVENTION In one aspect, the present invention provides an abrasive hand pad comprising: a coated abrasive component that is fixed to an abrasive layer that is also a 'back surface' of the major surface, wherein the abrasive layer comprises An abrasive particle and a first bonding agent, and a non-woven abrasive component fixed to the backing opposite to the polishing layer, wherein the non-woven, abrasive component comprises a second adhesive bonded to the non-woven elastic apertured fiber web Second abrasive particles. In some embodiments, the abrasive layer comprises a preparation layer, a slurry layer, and abrasive particles. In some embodiments, the abrasive layer comprises a shaped abrasive composite comprising a first abrasive particle and a first binder. In some embodiments, the coated abrasive component has a plurality of perforations extending through the abrasive layer and the backing. The abrasive hand pad of the present invention is suitable, for example, for abrading a workpiece surface. Accordingly, the present invention provides a method of abrading a surface of a workpiece, the method comprising: rubbing the abrasive hand pad of the present invention into frictional contact with the surface of the workpiece and moving at least one of the abrasive hand pad 157738.doc 201219155 or the workpiece to abrade the surface of the workpiece. The abrasive hand pad of the present invention substantially reduces or eliminates the problem of finger wear patterns while providing ergonomic benefits of having two types of abrasive in a single article. Moreover, it eliminates the need for permanent separation of the coated abrasive article from the non-woven abrasive article during the grinding process. The features and advantages of the present invention are apparent from the scope of the invention and the scope of the appended claims. These and other features and advantages of the present invention are described below in conjunction with the various illustrative embodiments of the invention. The above summary of the invention is not intended to describe the disclosed embodiments or the embodiments. The following figures and embodiments are more particularly illustrative of illustrative embodiments. [Embodiment] It should be understood that a person skilled in the art can devise various other modifications and embodiments, which are within the scope and spirit of the principles of the invention. The drawings may not be drawn to scale. Similar reference numbers in the drawings are used to indicate similar elements. Referring now to Figure 1, an exemplary abrasive hand pad 100 of the present invention includes a coated abrasive component 12 that is secured to a non-woven abrasive component 150. The perforations 105, as the case may be, extend through the coated abrasive member 丨2〇. As shown in Fig. 2A, the coated abrasive member 120A includes an abrasive layer 123 fixed to the major surface 125 of the backing 127. The abrasive layer 123 comprises a first abrasive particle 131, a preparation layer 133, a slurry layer 137, and optionally a supersize layer 139. The preparation layer 133 (and optionally the slurry layer 13 7) comprises a first binder 13 5 . Coated abrasives suitable for use as coated abrasive components include coated abrasives having a flexible, dense back 157738.doc 201219155 liner. As used herein, the term "flexible dense backing" means a substantially flexible and incompressible backing which does not comprise a foam (e.g., an open cell or closed cell foam) or a non-woven elastomeric open fiber web. Examples of suitable backings include cloth (e.g., woven or knitted fabric), vulcanized fibers, paper, nonwovens, polymeric films (e.g., polyester or polyolefin films), and multilayer combinations thereof. The anatomical backing may be a woven, knitted or stitched and may comprise cotton or cotton, rayon, rayon, silk, nylon (nyi()n) or its present. Exemplary non-woven backings can comprise cellulosic fibers, synthetic fibers, or blends thereof. The flexible, dense backing can comprise a backing treatment including, for example, a presize, a secondary slurry, a dip layer, and/or a tie layer. These processes can generally be performed in any order. The preparation layer can be formed by coating a crucible to prepare a layer of the crucible on the main surface of the back surface. The preparation layer precursor may include, for example, a gum, a phenol resin, an amine group J f sap, a urea-furfural resin, a melamine-formaldehyde resin, a urethane resin, a radical polymerizable polyfunctional (fluorenyl) acrylic acid. Esters (for example, amine-based plastic resins with pendant α, β-unsaturated groups, amino phthalate acrylate acrylates, isocyanurate acrylates), epoxy resins (including bis-butenylene)醯imine and hydrazine modified epoxy resin), isocyanurate resin and mixtures thereof. The preparation of the layer precursor can be applied using any of the known coating methods of coating the preparation layer on the backing, including roll coating, extrusion coating, curtain coating, knife coating, gravure coating. Method, spray method and the like. The basis weight of the preparation layer used may depend, for example, on the intended use, type of abrasive particles, and the nature of the coated abrasive article to be prepared, but will generally be 157738.doc 201219155 at 1 gram per square meter (gsm), 2 gsm, 5 gsm '1〇 (4) or i5 — to 20 gsm, 25 gSm, loo gsm, 2〇〇gm, 3〇〇 eggs, 4〇〇gsm or even 600 gsm. The preparation layer can be applied using any of the known coating methods of coating the preparation layer, such as a bond coat backing, including, for example, roll coating, extrusion coating, curtain coating, knife coating, gravure Printing coating method and spray coating method. Once the preparation layer precursor is coated on the backing, the abrasive particles are coated and embedded in the preparation layer precursor (for example, by dripping (dr〇p (3) state) / or electrostatic coating). The abrasive particles can be coated or placed on the preparation layer precursor arbitrarily or in a precise pattern. Examples of non-adhesive abrasive particles include fused alumina-based materials (such as alumina, ceramic alumina (which can Including one or more metal oxide modifiers and / or seed crystal or nucleating agent) and heat treatment oxidation, carbon carbide, co-melting alumina - zirconia, diamond, yttria, titanium diboride, cubic Crystalline nitriding butterfly, boron carbide, stone stone, sillimanite, silicon carbide, abrasive particles produced by sol-gel method, and blends thereof. Examples of sol-gel abrasive particles include those described in the following patents.

Usually this involves curing the precursor of the preparation layer to the B-stage, but a higher order cure can be used if desired. Curing to the B-stage can be accomplished, for example, using heat and/or light and/or using a curing agent, depending on the nature of the precursor of the selected layer to be prepared. Next, the at least partially cured prepreg and the abrasive particles are coated with a slurry layer precursor. The slurry layer can be formed by coating a curable slurry layer precursor onto the major surface of the backing. The slurry layer precursor may comprise, for example, a gum, a phenolic resin, an amine based plastic resin, a urea-furfural resin, a melamine-formaldehyde resin, an amine phthalate resin, a radical polymerizable polyfunctional (fluorenyl) acrylate ( For example, an amine-based plastic resin having a side-position α, β-unsaturated group, an acrylated urethane, an acrylated epoxy resin, an acrylated isocyanurate, an epoxy resin (including a bis-butene) Diimine and hydrazine modified epoxy resins, isocyanurate resins and mixtures thereof.

Or greater than 5 〇〇 gsm. The slurry layer precursor can be applied using any known coating method that coats the slurry layer precursor (eg, a slurry coating) on the backing, including, for example, roll coating, extrusion coating, curtain Coating method and spraying method. Once coated, the slurry layer precursor and the generally partially cured preparation layer precursor are sufficiently cured to provide a coated abrasive article that can be used. In general, this curing step involves thermal energy, but this is not required. Suitable forms of thermal energy include, for example, heat and infrared radiation. Exemplary sources of thermal energy include furnaces (e.g., suspension furnaces) 'heating rolls, hot blowers, infrared lamps, and combinations thereof.

The objects and advantages of the present invention are further described in the following non-limiting examples, but the specific materials and amounts thereof, and other conditions and details described in the examples are not to be construed as limiting the invention. EXAMPLES Unless otherwise stated, all parts, percentages, ratios, etc. in the examples and the remainder of the specification are by weight. Example 1 A mixed-grinding hand pad (4 吋 (10 cm) x 6 吋 (15 cm)) was prepared as follows: A piece of non-woven abrasive sheet was used with double-sided tape (multi-flex ABRASIVE SHEET ROLL S-UFN was obtained from 3M Company, St Paul, MN) is laminated to a backing of a coated abrasive sheet (grade P320, available from 316 U P320 9X1 1 GOLD FRECUT SHEET from 3M Company) to allow the non-woven abrasive sheet to coextend with the coated abrasive sheet. A steel plate coated with DUPONT 1147S 2K URETHANE PRIMER-FILLER automotive primer obtained from DuPont Automotive Finishes (Troy, MI) was hand-held using a variety of abrasive articles (as shown in Table 1) using a total of 20 strokes of linear motion. The average etch depth (Ra) was measured with a FEDERAL POCKET SURF III surface wheel ensemble (available from Federal Products Corp., Providence, RI) and the average of 5 independent measurements was recorded. The results are reported in Table 1 (below) . 157738.doc •16· 201219155 Table 1 Abrasive Type Type Ra, Standard Deviation, Microlobes, Micro 吋, (μm) (μm) 216U P320 9X11 54 (1.4) 4.6 (0.11) Comparative Example A GOLD FRECUT SHEET Coating Grinding Comparison Example B MULTI-FLEX ABRASIVE SHEET ROLL S-UFN Non-woven grinding 23 (0.58) 2.6 (0.066) Coating grinding 38 2.1 Example 1 Mixed grinding hand pad side (0.97) (0.053) Non-woven grinding 18 1.9 Grinding side (0.46) (0.048) Example 2 Using a manually operated pneumatically executed grinding apparatus (available from Hutchins Manufacturing Company (Pasadena, CA), HUTCHINS INDUSTRIAL PNEUMATIC SPEED SANDER, MODEL 3004), the mixed abrasive hand pad and coated abrasive sheet prepared in Example 1 were evaluated ( Level P320, available for 216U P320 9X11 GOLD FRECUT SHEET). The workpiece was a 18 inch (46 cm) x 24 inch (61 cm) metal cold rolled steel plate coated with DUPONT 1147S 2K URETHANE PRIMER-FILLER automotive primer. The steel plates were ground using a reciprocating (reciprocating) motion for 7 minutes and measured at specific time intervals. The amount of cut was measured by weighing the material removed from the steel plate at specific time intervals, and the depth of refraction (Ra) was measured with a FEDERAL POCKET SURF III surface profiler and the average of 5 independent measurements was recorded. The results are reported in Table 2 (below). 157738.doc -17- 201219155 Table 2 Abrasives 216UP320 9X11 GOLD FRECUT SHEET, Coated Abrasive Surface Hybrid Grinding Hand Pad, Coating Abrasive Surface Time 》 Cumulative Cutting Amount, Gram Ra, Micro 吋, (μm) Cumulative Cutting Amount Gram Ra, micro 忖, (micron) 30 2.70 44.4 0-13) 2.1 34.2 (0.869) 120 9.70 43.4 Π.10) 7.7 34.8 (0.884) 300 18.50 43.6 (1.Π) 17.4 35.4 (0.899) 420 21.50 41.2 ( 1.04) 20.9 34.6 (0.879) Example 3 Using a spray adhesive (available from HI-STRENGTH 90 SPRAY ADHESIVE from 3M Company), the back of the abrasive sheet will be coated with a grade P80 from 3M STIKIT GREEN CORPS SHEET GRADE 80D from 3M Company.
