RIGID OR FLEXIBLE, MACRO-POROUS ABRASIVE ARTICLE

摘要

A macro-porous abrasive article includes a spun lace substrate having a macro-porous structure and a coating. The coating is made of a resin binder and abrasive aggregates. The abrasive aggregates are formed from a composition of abrasive grit particles and a nanoparticle binder. The coating is at least partially embedded in the substrate. A method for making the macro-porous abrasive article includes combining abrasive aggregates of abrasive grit particles and a nanoparticle binder with a resin binder to form a slurry. The slurry is applied to a macro-porous support structure so that the slurry at least partially penetrates the substrate. The resin is then cured to bond the aggregate grains to the substrate.
