Structured abrasive article |
摘要 |
A coated abrasive article comprising a backing bearing on at least one major surface thereof abrasive composites comprising a plurality of abrasive grains dispersed in a binder. The binder serves as a medium for dispersing abrasive grains, and it may also bond the abrasive composites to the backing. The abrasive composites have a predetermined shape, e.g., pyramidal. The dimensions of a given shape can be made substantially uniform. Furthermore, the composites are disposed in a predetermined array. The predetermined array can exhibit some degree of repetitiveness. The repeating pattern of a predetermined array can be in linear form or in the form of a matrix. The coated abrasive article can be prepared by a method comprising the steps of: (1) introducing a slurry containing a mixture of a binder and a plurality of abrasive grains onto a production tool; (2) introducing a backing to the outer surface of the production tool such that the slurry wets one major surface of the backing to form an intermediate article; (3) at least partially curing or gelling the binder before the intermediate article departs from the outer surface of the production tool to form a coated abrasive article; and (4) removing said coated abrasive article from the production tool.
