Definitions
- Coated abrasive products are used to sand a wide variety of substrates, which can include soft, difficult to finish materials, such as painted surfaces. When finishing these soft materials the coated abrasive products cannot perform to their maximum potential because of premature loading. Loading is the coalescence of swarfs which clog the spaces between abrasive grains, thus preventing the abrasive product from being able to continue to effectively abrade the work substrate or surface.
- the abrasives industry approach is to utilize chemical compounds, such as metal soaps (i.e., zinc stearates, calcium stearates) applied as an oversize coating, or incorporated into the size coat, which is typically referred to as the first sizing coating.
- metal soaps i.e., zinc stearates, calcium stearates
- Stearate technology provides adequate stock removal and anti- loading characteristics.
- metal stearates leave a residue of low surface energy material on the work surface, that can potentially cause post-processing problems, such as coating defects in down stream painting processes.
- Contamination of this low surface energy material can be detected by measuring the water contact angle on the sanded substrate.
- the typical practice to address this issue is to clean the sanded surface with solvent wipes to insure that preferably all the contamination is removed, or finish with a non-stearated product.
- non-stearated products generally do not provide long life.
- an abrasive such as coated or composite abrasive, is oversized with a layer consisting essentially of an inorganic, anti-loading agent selected from the group consisting of metal silicates, silicas, metal carbonates, and metal sulfates.
- the layer consists essentially of the inorganic anti-loading additive and this is meant to indicate that the layer comprises no additive having organic components such as typify conventional anti-loading additives, including metal salts of organic acids, organophosphate, organosilicates, organoborates and the like. It does not however preclude the presence of a cured binder component that provides the vehicle by which the inorganic loading agent is applied.
- the metal silicates can be selected from the group consisting of magnesium silicates, potassium aluminum silicates, aluminum silicates, and calcium silicates.
- the magnesium silicates include talc
- the potassium aluminum silicates include micas
- the aluminum silicates include clays
- the calcium silicates include wollastonite.
- the silicas can be selected from the group consisting of fused silica, fumed silica, and precipitated amorphous silica.
- the metal carbonates can include calcium carbonate.
- the metal sulfates can include hydrous calcium sulfate or anhydrous calcium sulfate.
- the anti-loading agent can have a Mohs hardness value of less than about 7, and preferably less than about 3.
- the anti-loading agent can have a mean particle diameter size of less than about 30 micrometers and preferably in the range of between about 1 and about 20 micrometers. This allows the anti-loading agent to form sufficiently small particles that combine with swarf from a sanded surface, such as a painted metal surface, to prevent sufficient agglomerating loading of swarf in a surface of the coated abrasive.
- the particles of the anti-loading agent are of such a size that, upon sanding a painted surface using the coated abrasive to produce abraded swarf, particles of the anti-loading agent are released that combine with and inhibit the agglomeration of such swarf particles.
- the concentration of the anti-loading agent is concentrated predominantly in the oversized layer.
- the concentration can be at least 10 percent, by volume, and preferably at least about 60 percent, by volume, of the oversized layer.
- the anti-loading agent is preferably dispersed in a binder, for example, comprising a thermoplastic or thermoset resin.
- the thermoplastic resin can include latex and the thermoset resin can be selected from the group consisting of urea formaldehyde, phenolic, epoxy, urethane, and radiation curable resin systems.
- An abrasive such as a coated or composite abrasive, is also provided which includes a backing layer having a first surface, an abrasive layer having a plurality of abrasive particles disposed on the first surface of the backing layer, and a layer consisting essentially of an inorganic anti-loading agent disposed over the abrasive layer.
- the anti-loading agent is deposited on a cured size coat.
- a method for forming an abrasive such as a coated or composite abrasive, is also provided which includes attaching a plurality of abrasive particles to a first surface of a backing layer and depositing a layer consisting essentially of an anti- loading agent over the abrasive particles.
- Coated abrasives generally comprise those products having abrasive grits adhered to a support backing which can be used to abrade or otherwise wear down a surface of an article to which they are applied.
- the support backing of a coated abrasive may be rigid, but generally is flexible and typically comprises a web of material, such as paper, cloth, fibrous pad, polymeric film, vulcanized fiber, or a combination of such materials and the like.
- the support backing initially includes a collection of loose fibers, to which the abrasive grits are added, with or without further binder material, to provide an abrasive web having grits throughout.
- the loose collection of fibers and grits may be compressed, if no adhering binder is present, or otherwise fixed or cured when a binder is present to form the coated abrasive.
- the abrasive grits can generally be any material which has the capability of abrading the workpiece article and typically includes sand, flint, corundum, metallic oxides such as aluminum oxide, aluminum-zirconia, ceramic alumina, diamond, silicon carbide, garnet, rouge, crocus, and the like.
- the grits typically have sharp edges which act as the abrading means, but the quality and quantity of the sharp edges depends upon the utility.
- the grits can be embedded into or intermingled with the support backing, but, more typically are adhered to the support backing by an appropriate binder material.
- the grits can be applied or intermingled with the web in a specific pattern or grain or may be randomly distributed.
- the binder material is generally any convenient material which can act to adhere the grits to the support backing and have resistance to negating the abrading process.
- Typical binder materials include the phenolic resins, hide glues, varnishes, epoxy resins, acrylates, multi-functional acrylates, urea-formaldehyde resins, trifunctional urethanes, polyurethane resins, lacquers, enamels and any of a wide variety of other materials which have the ability to stabilize the grits in adhering relationship to the support backing.
- the binding material is carefully chosen to provide maximum efficiency of the coated abrasive for the abrading surface contemplated. Care is taken in selecting binder materials which can resist softening or burning or both due to overheating yet provide adequate adherency.
- the grits can be sprayed or otherwise coated with the binder material and deposited on or about the support backing, or the support backing may be coated with the binder material and the grits thereafter deposited thereon.
- Many alternate forms of support backings, granular materials, binder materials, means of arranging the grits on the support backing, means of adhering the grits and the like are known in the prior art and are seen as variation contemplated as within the scope of this invention.
- a backing (with or without a pre-treatment), is given a maker coat of a binder resin is applied and, while the resin is still tacky, abrasive grits are applied over the maker coat, and the binder is cured so as to hold the grits in place.
- a size coat comprising essentially a binder resin and optionally fillers, grinding aids and the like, is then applied over the grits and cured.
- the primary function of the size coat is to anchor the grits in place and allow them to abrade a workpiece without being pulled from the coated abrasive structure before their grinding capability had been exhausted. In some cases, a supersize layer is deposited over the size coat.
- This layer is to place on the surface of the coated abrasive an additive that provides a special characteristic, such as enhanced grinding capability, surface lubrication, anti-static properties or, in this case, anti-loading properties.
- the supersize layer generally, but not necessarily, plays no part in securing the grits in place on the coated abrasive.
- the additive may be applied as a dispersion in a binder (which will be subsequently cured), or in a liquid dispersion which will simply dry leaving the additive on the surface.
- the binder includes a thermoplastic or thermoset resin.
- the thermoplastic resin can include latex and the thermoset resin can be selected from the group consisting of urea formaldehyde, phenolic, epoxy, urethane, and radiation curable resin systems. With some additives, adhesion to the surface can be achieved without the need for a dispersion medium.
- the anti-loading agents can be selected from the group consisting of metal silicates, silicas, metal carbonates, and metal sulfates.
- the metal silicates can be selected from the group consisting of magnesium silicates, potassium aluminum silicates, aluminum silicates, and calcium silicates.
- the magnesium silicates include talc
- the potassium aluminum silicates include micas
- the aluminum silicates include clays
- the calcium silicates include wollastonite.
- the silicas can be selected from the group consisting of fused silica, fumed silica, and precipitated amorphous silica.
- the metal carbonates can include calcium carbonate.
- the metal sulfates can include hydrous calcium sulfate or anhydrous calcium sulfate.
- the inorganic anti-loading agent in the course of use, appears to release fine particles that coat fine swarf particles generated by the grinding process thus preventing them form agglomerating to form troublesome larger particles that get trapped on the coated abrasive surface, (known as "loading"), reducing its effectiveness.
- loading fine particles that coat fine swarf particles generated by the grinding process thus preventing them form agglomerating to form troublesome larger particles that get trapped on the coated abrasive surface, (known as "loading"), reducing its effectiveness.
- loading fine a fine coat of low energy material is smeared on the abraded surface which makes subsequent painting or polishing of the surface very difficult unless this coat is removed.
- the anti-loading agent of the present invention in one embodiment, is relatively soft, for example, having a Mohs hardness value of less than about 7, and preferably less than about 3.
- the loading agent has a mean particle diameter size range of less than about 30 micrometers and preferably between about 1 and about 20 micrometers as finer particles size materials appear to function better as an anti-loading agent.
- the anti-loading agent to prevent the swarf particles from adhering to each other, therefore reducing loading.
- This approach produces fine dust during sanding, while without the inorganic anti-loading agent, the swarf tends to form balls or large chips which become lodged in between the grain particles, which prevent effective grinding, and reduce the life of the coated abrasive.
- the difference in the appearance of the swarf resulted from sanding with stearated and non-stearated products are visible.
- the concentration of the anti-loading agent in a sanding surface of the oversized layer is greater than about 10 percent, by volume, and preferably greater than about 60 percent. This assures the anti- loading agent is sufficiently present to be effective to produce the find dust which prevents the swarf from agglomerating.
- the anti-loading agent can be used with other abrasives, such as composite
- Example 1 Hydrous Magnesium Silicate (Talc) in different median particle sizes
- the backing material is an A-weight paper and the make coat and size coat comprise a urea-formaldehyde binder.
- the abrasive particles are P320 aluminum oxide.
- an oversize coat is applied comprising an anti-load additive. In one case, no additive was applied for comparative purposes. In a second case, an oversize coating containing zinc stearate is applied and in three other cases the applied coating was hydrous magnesium silicate (talc) with different particle size.
- talc hydrous magnesium silicate
- the coated abrasives were then used to abrade an acrylic panel using a dual action sander for six contacts of two minute interval each.
- the grinding was done by a 12.7 cm (5-inch) disc with a 4.5 kg (10-lb.) load.
- the amount of cut after the total grinding time of 12 minutes was recorded, and the grinding performance was measured as percent cut of the control.
- the average surface roughness values, Ra (the arithmetic average of roughness) were also measured. The results are recorded in the Table 1 below which demonstrates that talc is as effective as the more conventional zinc stearate.
- Example 2 Hydrous Magnesium Silicate (Talc). Supreme HT in different grit sizes
- Example 3 Amorphous Silica. Calcium Silicate (Wollastonite). Aluminum Silicate (Clay), and Potassium Aluminum Silicate (Mica).
- a standard P320 grit A-weight paper aluminum oxide conventional coated abrasive is used.
- an oversize coat comprising an anti-load additive of either Amorphous Silica, Calcium Silicate (Wollastonite), Aluminum Silicate (Clay) or Potassium Aluminum Silicate (Mica).
- MN-23 is amorphous silica available from Eagle Pitcher.
- Wollastonite 325 is a calcium silicate available from NYCO Minerals, Inc.
- Optiwhite is clay available from Burgess Pigment Company.
