Description

COATED ABRASIVE PRODUCTS AND PROCEDURES TO FORM THEMSELVES CROSS REFERENCE TO RELATED REQUESTS FIELD OF THE INVENTION The present invention is directed generally to coated abrasive products, and in particular, to coated abrasive products and processes for forming them that employ a binder formulation having multiple healing paths.

BACKGROUND OF THE INVENTION The coated abrasive products primarily include a substrate or support element that serves as a dimensionally stable component, onto which a layer containing the abrasive is deposited. In traditional coated abrasives, the abrasive grains of the abrasive layer are adhered to the support member through the use of a coating marker, which is an adhesive binder composition for anchoring the abrasive grains as they are deposited. More commonly, processing continues with the deposition of a cover of a size that allows structural integrity to the abrasive layer.

In the context of traditional coated abrasives, the abrasive grains are generally oriented in a random fashion and form a fairly uniform layer. Structured or designed abrasives have been developed to provide improved performance over traditional coated abrasive products. Structured abrasives also generally use a support element, although the abrasive layer is deposited in order to form a pre-configured pattern. Such structured abrasives generally exhibit improved spray characteristics over conventional abrasive products, such as providing a sustained cutting index, consistent surface finishing and a long life. In the context of both traditional coated abrasives and structural abrasives, thermally curable binders have been used to adhere the abrasive layer to the support element or substrate, as well as to stabilize the abrasive grains.

However, thermal curing suffers from numerous disadvantages which often include extended cure times which result in undesirable change in the position of the abrasive grains. Particularly, in the context of structured abrasives, the grain pattern can be altered during the rheological changes of the binder formulation during heating and / or during handling of the structured abrasive prior to or during heat treatment.

In an effort to orient said disadvantages, so-called agglutinating systems that can be cured by radiation have been developed, which advantageously allow to cut the healing cycles. Such binders that can be cured by radiation include binders that can be cured with UV, as well as binders that can be cured with an e-beam. However, the binders that can be cured by radiation are also free of disadvantages. For example, particularly in the case of abrasives based on silicon carbide, the penetration depth of the radiation is limited. Additionally, dyes present within the binder formulation can cause drawbacks with radiation penetration as well, resulting in incomplete cure. In an effort to orient the processing and performance characteristics associated with known coated abrasives, and in particular with structured abrasives, U.S. Pat. Nos. 5,863,306 and 5,833,724 describe various coated abrasives formed using a binder formulation that combines components that can be cured by radiation and components that can be cured in thermal form. During processing, the viscosity is modified through the use of a functional powder that is added to a coated intermediate product before curing. Functional powder intends to adjust a viscosity of the intermediate product, to retain the structural integrity during the processing, in such a way that the designed shape is maintained before and during the cure. Regardless of the advances provided in the art, as exemplified, for example, in Patents '306 and' 724, there continues to be a need for superior coated abrasives and methods to form them, and which additionally allow for manufacturing operations on a large scale.

BRIEF DESCRIPTION OF THE INVENTION According to a first embodiment, a coated abrasive product includes a substrate, and an abrasive layer that covers the substrate. The abrasive layer includes abrasive grains and a binder, the binder being formed from a binder formulation including first and second binder compounds blended together uniformly with the abrasive grains. The first binder compound can generally be cured by radiation and the second binder compound desirably is in powder form, and can be cured in a thermal form. According to another embodiment, a method for forming a coated abrasive product includes mixing an agglutinating formulation with abrasive grains to form an abrasive dispersion, the agglutinating formulation including a mixture of first and second agglutinating compounds. The first agglutinating compound can be cured by radiation and the second binder compound generally has a powder form, and can be cured in thermal form. The process continues with the coating of a substrate with the abrasive dispersion to form a coated intermediate, and performing the curing operations. The cure is performed by irradiating the coated intermediate to cure the first binder compound, and thermally treating the coated intermediate to cure the second binder compound.

DESCRIPTION OF THE PREFERRED MODALITIES In accordance with one aspect of the present invention, a coated abrasive product is provided, generally including a substrate and an abrasive layer covering the substrate. The abrasive layer includes abrasive grains and a binder, the binder being formed from an agglutinating formulation. In a particular embodiment, the binder formulation includes first and second binder compounds that are blended together uniformly with the abrasive grains. Normally, the first binder can be cured by radiation, and the second binder is formed of a powder that can be cured in thermal form. Each of the first and second agglutinators can have only a single cure path. That is, each binder can be mono-curable, such that only a single cure methodology can be used to cure the particular binder compound. For example, as noted above, the first binder can be mono-curable in such a way that it can only be cured by irradiation, while the second binder is mono-curable, which can be cured only by a heat treatment. Returning to the particularities of the agglutinating formulation, as noted above, one of the agglutinating compounds, can generally be cured by radiation, such that it can be cured by UV, cured by e-beam, or can be heal by microwave. A particularly useful UV binder composition contains the constituents chosen from the group of acrylate and methacrylate oligomers and monomers. Useful oligomers include epoxy acrylates, aliphatic urethane acrylates, aromatic urethane acrylates, polyester acrylates, aromatic acid acrylates, epoxy methacrylates, and aromatic methacrylates. The monomers include mono, di, tri, tetra and pentafunctional acrylates, such as trimethylpropane triacrylate, trimethylolpropane triacrylate, tris (2-hydroxyethyl) isocyanurate triacrylate, tripropylene glycol diacrylate, hexanediol diacrylate, octyl acrylate, octyl acrylate and decyl acrylate. . The binder formulation may include substantial amounts of acrylate monomers containing 3 or more acrylate groups per molecule. Typically, commercial products include trimethylpropane triacrylate, (TMPTA) as noted above, as well as pentaerythritol triacrylate (PETA). The relative amounts of di and tri-functional acrylates, as well as higher molecular weight acrylate oligomers can be adjusted together with the other components to provide the rheological properties suitable for processing and the appropriate hardness and cut characteristics of the final product. after the healing. Additionally, the coupling agents can be used to improve the bond between the adhesive grains and the abrasives. Typical coupling agents include organosilanes, for example A-174 and A1100 available from Osi Specialties, Inc., and organotitanates and zircoaluminates. A particular group of coupling agents include aminosilanes and methacryloxy silanes. The fillers can be incorporated into the dispersion to modify the rheology of the dispersion and the hardening and hardness of the cured agglutinators. Examples of useful fillers include: metal carbonates such as calcium carbonate, sodium carbonate, silicas, such as quartz, glass beads, glass bubbles; silicates such as calcium, clays, calcium metasilicate; metal sulfates such as barium sulfate, calcium sulfate, aluminum sulfate; metal oxides such as calcium oxide, aluminum oxide (such as in the form of boehmite and / or pseudos boehmites); and aluminum trihydrate. The dispersion may comprise a spray aid to increase the spray efficiency and the cutting index. Useful spraying aids may be of inorganic base, such as halide salts, for example, sodium cryolite, tetrafluous potassium steal, etc .; or with an organic base, such as chlorinated waxes, for example, polyvinyl chloride. A particular embodiment includes cryolite and potassium tetrafluoroborate with a particle size that varies within the range of 1 to 80 microns, and more preferably 5 to 30 microns. The percentage by weight of the spray aid varies from 0 to 50%, and more preferably from 10 to 30% of the complete formulation (including the abrasive components). In addition to the above constituents, other components can also be added: usually a photoinitiator such as an ether benzoin, ketal benzyl, α-alkoxy-acetophenone, α-hydroxy-alkylphenone, α-amino alkylphenone, acylphosphine oxide, benzophenone / amine, toxanthone / amine, or other free radical generator; anti-static agents, such as graphite, black carbon and the like, suspending agents, such as fumed silica, anti-loading agents, such as zinc stearate, lubricants such as wax, wetting agents; dyes; fillers, viscosity modifiers; dispersants; and defoamers. Returning to the second binder compound, various polymers can be used which can be cured in thermal form. Although thermoplastic and thermoadjustable polymers, thermoadjustable polymers are often preferred because of their stable nature, particularly in the context of cutting and finishing operations that generate excessive heat. According to a particular development, the second agglutinating compound is comprised of a powder, normally formed mainly of a powder or even essentially powder in its entirety. In general, polymers that can be cured in liquid thermal form are excluded in favor of the powders. The powder forms thermally curable agglutinators that are particularly advantageous, so that they can be incorporated into a process flow to form coated abrasives rather easily. In fact, the use of a thermally curable binder in powder form is particularly advantageous for the creation of abrasive dispersions used to form structured abrasives. Additionally, it has been discovered that the use of components that can be cured in powder form have been shown to provide improved abrasive performance in the final product, as well as provide abrasive dispersions that have improved processing capacity due at least in part to beneficial changes in the viscosity of the dispersions. Examples of curable thermal polymers include epoxy resins, urethane resins, phenolic resins, urea / formaldehyde, melamine / formaldehyde, acrylic resins, polyester resins, vinyl, and mixtures thereof, provided said resins are used in powder form instead of liquid form. It should be understood that such resins are available in any form and that the powder or particle form is hereby preferably used. The abrasive grains can be formed from any or a combination of the known abrasive grains, including alumina (fused or sintered), zirconium, zirconium / alumina oxides, silicon carbide, garnet, diamond, cubic boron nitride and combinations of the same. The particular modalities have been created by the use of dense abrasive grains comprised primarily of alpha-alumina. The abrasive particles generally have an average particle size of 1 to 150 microns, and more typically of 1 to 80 microns. However, in general, the amount of abrasive present provides from about 10 to about 90%, such as from about 30 to about 80% of the weight of the formulation.

The support element can be formed of flexible though mechanically stable materials, including various polymer films, paper or other cellulosic materials and fabrics including cotton and polyester with various polymeric saturators. A particular type of support element or substrate is the polyethylene terephthalate film. Other polymeric films include polycarbonate films. The support elements can be primed or pretreated to promote adhesion between the abrasive layer and the support element. The details of the radiation-curable binding component, the additives with respect thereto, the support element and the abrasive grains can be found in the U.S. Pat. 5,014,468 commonly owned by the present Beneficiary, incorporated herein by reference. Returning to a particular aspect of the present invention, the following description focuses on structured abrasives, which generally have a high pattern of the abrasive material, as well as the methods for making the same. Figure 1 illustrates a basic process flow for the continuous manufacture of a coated abrasive product 10, and in particular, a structured or designed coated abrasive product. At this point, a support member 12 is extracted from a roller 42 provided on a non-shrouded platform. The non-wrapped platform is adjusted with a brake, in accordance with the usual practice to provide a desired resistance for unroll the support element. The support member 12 is moved from the non-shrouded area around one or more suitable rolls designated by the reference numerals 44, 46, 48 and 50, and to the coating area generally denoted by the reference numeral 52, in FIG. where it is passed between the biter formed by the roller 53 and the patterned roller 56, which rotates in the directions indicated by the arrows. The pattern roller is a type of tool for imparting three-dimensional structures that can be used in accordance with the embodiments of the present invention. The support element 12 with the abrasive coating 14 coated thereon is passed around one or more rollers 58, 60 to a cutting station 62 having a radiation source, such as and an e-beam source or source. of actinic light, that is, a source of ultraviolet (UV) light, to cure a portion of the agglutinating formulation. The curing station 62 may additionally include a downstream thermal source of the UV light source, to complete the curing of the product. Alternatively, the thermal source may be provided off-line. For example, following a partial cure using only radiation, the product partially cured in this way can be rolled and cured in a coiled form in a heat curing oven (cured by volume), or it can be routed through another coil process to coil that contains a thermal curing station (linear or non-linear curing). According to one aspect, the use of a first binding compound that allows to cure in line, fast, the last stage of healing it may occur off-line from a curing operation by volume, while maintaining the desired structural characteristics of the adhesive layer. The rollers 64, 66, route the coated abrasive material 10 to move horizontally through the healing zone. From the curing zone, the coated abrasive material 10 is moved over the roller 68 for a conventional removable assembly generally denoted by the reference number 70 and which includes a roller 72, a roller covered with plastic 74 and compressed air that drives the removable roll 76 to provide a roll wrapped with coated abrasive material. The radiant energy of the actinic light source can be supplied by any conventional UV source. For example, in the practice of the present invention, the coatings were exposed to UV light generated from bulbs V, D, H, or H +, or a combination thereof at an energy output that varies from 39 watts per centimeter wide at 236 watts per centimeter wide. The pattern formed in the support member through contact with the patterned roller may comprise islands of isolated formulation, or a pattern of folds separated by valleys. The patterns are generally designed to provide an abrasive product with a plurality of spraying surfaces equidistant from the support with the area of the spray surface increasing the erosion of the layer. Between Spray surfaces are often provided with channels that allow the circulation of spray fluids and the removal of chips generated by spraying. In addition, the tool used to make the pattern and deposit the abrasive composition, can be heated or cooled, in such a way that it contributes to the elevation of the viscosity to produce the plastic surface of the formulation but not the fluid. However, the heating may not be of a level such that the binder is cured while in contact with the tool. By adjusting the viscosity of the resin formulation or the surface layer, the pattern is retained substantially to allow cure and handling, such as for at least about 30 seconds and preferably at least 60 seconds. Although the above embodiment has been described specifically in relation to the use of a pattern roller, other pattern formation techniques can be used. In a relatively simple form, a suitable substrate can be coated with an abrasive formulation, and then the pattern formed by contact with a embossing tool, such as a pattern forming seal or a nodular steel roll. According to a particular development, the dispersion or abrasive composition makes use of a thermal cure polymer in powder form, combined with the radiation curative polymer with a abrasive component and additional components as detailed above. Typically, the particle size of the thermal cure polymer can vary from sub-microns to 500 microns. The change of particles can be used to modify the rheological properties of the coating, as well as the final mechanical properties. The incorporation of an agglutinating resin in the form of a powder also allows the processing of pastes with auxiliary content of abrasion, filler and low pulverization, which could not be processed when they are made only with a binder in liquid form. Returning to Figure 2, a cross-sectional view of a structured abrasive embodiment is illustrated. In particular, structured abrasive product 200 includes a substrate or support element 205 on which a layer of abrasive 208 is provided. Abrasive layer 208 includes, in cross section, elevated characteristics 210. The profile of the features Elevations 210 may vary considerably based on the intended end use. In the modality shown, the features 210 have a generally inclined and triangular cross section, ending in a sharp peak 214 that forms a cutting surface, and / or a flat cutting surface 216. The various features can be related through an underlying matrix 121. or they can be separated from each other by the empty spaces in the abrasive material as illustrated in portion 225, which generally exposes a portion of the support element 205. As can be seen in a perspective view, the Structured abrasive has a contiguous polygonal pattern that is usually repeated. It should be noted that the portions of the pattern can be broken, forming only the localized patterns of contiguous elevated characteristics. Returning to Figures 3 to 5, various embodiments of structured abrasives are described. These figures represent the graphic representations of the real SEM photos that show, in an example form, different geometric patterns. Figure 3 shows surface features with a hexagonal shape arranged in an ordered group. Figure 4 shows generally linear surface features that have a substantially complete aspect ratio, defined as the ratio of the length of the surface feature to the next longest dimension, at this point, the width. The aspect ratios of 10, 100 or even greater are typical. Figure 5 shows a group of square surface characteristics (in horizontal cross section). As shown, each surface feature forms a pyramid, which has four larger lateral surfaces that end in a peak. The valleys between the surface features may be completely devoid of abrasive material, although in the embodiments shown, the valleys generally contain a comparatively thinner portion of the abrasive layer.

EXAMPLES EXAMPLE 1 Off-center wet spraying of stainless steel Tested products: Novolac Varbum 94-345 heat-adjustable powder from OxiChem was added in a designed formulation of control abrasives to evaluate the effect of heat-adjustable powder, providing thermal cure functionality to the binder formulation, in spraying performance in spray application Decentered wet. The modified and control formulations were coated on a polyester cloth substrate and processed under the same conditions to produce the designed abrasive product, which included exposure to UV radiation in a UV fusion unit. The product containing Novolac was further cured thermally at a temperature of 121 ° C for 3.5 hours. The formulations are related in Table 1.

Test machine tool: An off-center sprayer, constant feed ACME Model 47 was used for the complete test procedure. The machine consists of four main components that include the adjusting wheel, the work support blade, the contact wheel and the abrasive belt.

Work material: a group of 304 stainless steel work pieces, cylindrical 29, each measuring 3.67 centimeters x 24.5 centimeters at the start of the test. Test procedure: The products were flexed and converted into bands of 10.16 centimeters x 137.16 centimeters to test in the off-center spray. Prior to spraying any work pieces, the following parameters were checked in the machine tool: Wheel angle adjustment was adjusted to 5 °. The axes of the adjustment and contact wheel were confirmed parallel to each other. The regulating wheel and the contact wheel were coated. The rest of the working nylon was ground clean. The work guides were adjusted to allow the cleaning of suitable parts. The test procedure followed the sequence of steps indicated below: The work pieces were previously ground to remove surface defects. The weight of each piece of work was recorded. The machine was adjusted for the desired feed by 0.015 centimeters and the speed of the adjusting wheel was adjusted to 53 RPM. Two bars were passed through the machine, this was counted as a step. During the grinding of a coolant fluid containing a rust inhibitor, it is sprayed onto the abrasive belt. The weight of each piece of work was recorded to calculate the metal removed. The thickness of the band and the elongation of the band were measured. Feeding was additionally increased by an additional 0.015 centimeters, two more rods were sent through the machine and measurements of weight, thickness, and elongation were taken again. These steps were repeated until the product was worn to the support. Test results: the formulation with the addition of the Novolac powder exhibited improved wear resistance over the control formulation. This lasted 5 steps compared to 4 for the control formulation. Even with a lower abrasive grain content than in the control, the product with Novolac powder (or similar to phenol / formaldehyde-based powders) achieved a greater stock removal. Additionally, the cutting to wear ratio for the Novolac powder product is significantly better than the control product.

TABLE 2 EXAMPLE 2: Compound sanding discs Test products: products were tested in impurities of two sizes: 9 micras and 30 micras. For each size of impurity, a control formulation was made with a binder consisting only of resin that can be cured with UV, and a modified formulation containing a thermoadjustable powder based on acrylic was elaborated in addition to the resin that can be cured with UV. The modified and control formulations were coated on a polyethylene terephthalate film substrate and processed under the same conditions to produce the designed abrasive product, which includes exposure to UV radiation in a UV Fusion unit. The products with the thermo-adjustable powder received an additional thermal cure at a temperature of 121 ° C for 4 hours.

Thermoadjustable acrylic powder: 158C121 of Ferro VEDOC powder coatings. Working materials: composite panels of 15.24 centimeters x 60.96 centimeters x 1.27 centimeters were used for the test. Equipment: the products were tested on an automated sander machine designed for test discs for random orbital sanders. The machine consists of a random orbital sander of Dynbrade mounted on an arm that alternates in a group of striking length. The machine works by starting the disc, lowering the arm to place the sander against the work piece, moving the sander back and forth on the workpiece at a set pressure and for an established amount of time, and subsequently, raising the sander away from the work piece. A scale is used to measure your weight; A surface analyzer is used to measure the surface finish; and a brightness meter is used to measure the brightness. Test procedure: it was cleaned and a dry cloth was passed to the composite panel, and its weight was recorded. The stroke length of the machine was adjusted to 50.8 centimeters and the downward force on the abrasive disk was adjusted to 453 grams. The panel was placed on the sanding machine and the machine was turned on for 1 minute. The transverse speed of the sander through of the workpiece was approximately 10.16 cm / sec. Water is sprayed onto the surface of the solid surface panel using a spray bottle during the sanding test. After a minute of sanding on the machine, the panel was removed from the machine, cleaned with water and wiped dry. The panel was weighed and the weight loss recorded. A surface analyzer was used to register Ra, Ry and Rmax. A brightness meter was used to record the brightness reading at 20, 60 and 85 degrees. The panel was placed back on the sander, sanded for one minute, cleaned and measured. This procedure was repeated until 12 minutes of sanding was achieved on the panel.

Results of the test The results of the grind are summarized in Table 7. The formulations with the thermo-adjustable powder had significantly better wear resistance over the control formulations. The weight loss of the formulations, both 9 microns and 30 microns with the heat-adjustable powder after 12 minutes of wet sanding was only 0.1 gram compared to 7.4 and 10.6 grams respectively, for the control counterparts. The proportion G, defined as the proportion of the removal of the stocks to produce the weight loss, was also substantially improved for the formulations with the thermo-adjustable powder (125 and 43 against 0.54 and 0.77). Additionally, the products with thermoadjustable powders achieved final brightness values much greater than the control formulations on polished solid surfaces, which is a critical performance criterion for this application. In summary, the addition of plastic powder improved the wear resistance, the G-ratio and the final gloss values of the polished solid surfaces by a surprisingly considerable amount. TABLE 7 According to the embodiments described above, the coated abrasives, and in particular, the structured or designed coated abrasives, are described having a particular binder formulation, which not only improves the processability, but also manifests itself in performance characteristics. notable as summarized above. In addition, the use of a first and second different agglutinating compounds as described in connection with the various embodiments described above, allows a better flexibility arrangement in the choice of agglutinating composition. In contrast, before the use of Vd.-functional compounds that have functional groups designed different in a single binder compound that suffers from a reduced process flexibility and are significantly more difficult to design and implement. The subject matter of the material described above will be considered illustrative, and not restrictive, and the appended claims are intended to embrace all such modifications, improvements and other embodiments, which are within the scope of the present invention. Accordingly, to the maximum extent permitted by law, the scope of the present invention will be determined by its broader permissible interpretation of the following Claims and their equivalents, and should not be restricted or limited by the foregoing detailed description. For example, although the above makes specific reference to different agglutinating compounds that can respectively be cured by radiation or in thermal form, the binder that can be cured by relatively rapid radiation can be replaced with alternative binders. For example, a catalyst coated with fast curing epoxy that is cured rapidly by heat treatment can be used. Alternatively, a fast / blocked urethane curing catalyst that is cured rapidly by heat treatment can be used. In this regard, the first binding compound generally desirably maintains its fast curing properties, combined with the relatively slower, more robust second cure binder compound.
