Abstract
An abrasive article may include an organic bond material, abrasive particles contained within the organic bond material and a plasticizer contained within the organic bond material. The plasticizer may include at least one of an aromatic phenyl group, a heteroaromatic furyl group, or a saturated aliphatic hydrocarbon. The plasticizer may further include a polar group.
Claims17
An abrasive article comprising:
- an organic bond material;
- abrasive particles contained within the organic bond material;
- and
- a first plasticizer contained within the organic bond material,
- wherein the first plasticizer comprises at least one of an aromatic phenyl group, a heteroaromatic furyl group, or a saturated aliphatic hydrocarbon, and wherein the first plasticizer comprises at least one polar group,
- wherein the first plasticizer is a compound selected from the group consisting of methyl benzoate, ethyl benzoate, propyl benzoate, methyl anthranilate, 2′-aminoacetophenone, α-amylcinnamaldehyde, m-anisaldehyde, p-anisaldehyde, cuminaldehyde, dimethyl anthranilate, ethyl 2-aminobenzoate, 4-ethylbenzaldehyde, o-tolualdehyde, salicylaldehyde, p-tolualdehyde, and combinations thereof, and
- wherein the abrasive article further comprises a ratio AACPL/AACOBM of at least about 0.01 and not greater than about 0.25, wherein AACPL is a content of plasticizer in weight percent for a total weight of the abrasive article and AACOBM is a content of organic bond material in weight percent for a total weight of the abrasive article.
