Abstract
The present disclosure relates to abrasive buffing articles (“abrasive buffs”) and methods of making the same. The abrasive buffs include a substrate, such as a fabric, that has been impregnated with an abrasive polymeric composition that includes abrasive particles, such as primary abrasive particles and/or abrasive aggregates, such as spray dried abrasive aggregates. The abrasive buffs are flexible and capable of conforming to and effectively abrading, polishing, and buffing workpieces possessing a complex geometry.
Claims21
A fixed abrasive buff comprising:
- a plurality of fixed abrasive cloths;
- and
- a central hub,
- wherein the fixed abrasive cloths are attached to the hub,
- wherein each abrasive cloth comprises
- an abrasive composition fixed to a fabric,
- wherein the fabric comprises a woven fabric, a nonwoven fabric, or a combination thereof, wherein the abrasive composition comprises a polymeric binder and a plurality of abrasive particles dispersed in the polymeric binder,
- wherein the abrasive composition is disposed within the fibers of the fabric,
- wherein the fabric comprises a thickness of at least 50 microns to not greater than 2000 microns,
- wherein the abrasive composition comprises a thickness of at least 60 microns to not greater than 300 microns, and
- wherein the abrasive buff comprises a ratio of fabric thickness to abrasive composition thickness ranging from of 1:0.2 to 1:0.8.
A fixed abrasive buff comprising:
- a plurality of fabric layers;
- and
- an abrasive composition fixed to each of the fabric layers,
- wherein the abrasive composition is disposed at least partially within each of the fabric layers,
- wherein the abrasive composition comprises a polymeric binder and a plurality of abrasive particles dispersed in the polymeric binder, wherein the fabric layer comprises a nonwoven spun bond point bond fabric, and wherein the polymeric binder the polymeric binder comprises a styrene butadiene composition having a glass transition temperature (Tg) of at least −30° C. and not greater than 20° C., wherein the fabric comprises a thickness of at least 50 microns to not greater than 2000 microns, wherein the abrasive composition comprises a thickness of at least 60 microns to not greater than 300 microns.
