Title
(EN) ABRASIVE ARTICLES WITH ENCAPSULATED LUBRICANT
(FR) ARTICLES ABRASIFS A LUBRIFIANT ENCAPSULE
Abstract
(EN)
Abrasive articles having an encapsulated lubricant are described. In one aspect, the articles are characterized by a base substrate comprising a plurality of polymeric fibers adhered to one another at mutual contact points, the substrate having a base weight within the range from 20 to 10,000 g/m2, abrasive grains adhered to the substrate and a plurality of lubricant capsules adhered to the substrate the capsules comprising a continuous shell with lubricant therein, and the shell comprising a cured thermosetting resin. In another aspect, a composite abrasive article is characterized by at least two layers of the aforementioned abrasive article compressed together and adhered by a binder, the composite article having a flexural modulus of not more than 100 kgf/cm2.
(FR)
L'invention concerne des articles abrasifs dans lesquels un lubrifiant est encapsulé. Dans un aspect de l'invention, les articles se caractérisent par un substrat de base comprenant une pluralité de fibres polymères collées les unes aux autres en des points de contact mutuel, le substrat présentant un poids de base de l'ordre de 20 à 10 000 g/m2, des grains abrasifs collés sur le substrat et une pluralité de capsules de lubrifiant collées au substrat, lesquelles comprennent une enveloppe continue en résine thermodurcissable contenant le lubrifiant. Dans un autre aspect de l'invention, un article abrasif composite se caractérise par au moins deux couches comprimées de l'article susmentionné, collées l'une à l'autre par un liant, l'article composite présentant un module de flexion ne dépassant pas 100 kgf/cm2.
