Beschreibung
Zusammenfassung:	A wear-resistant composition which includes a polymeric hot-melt binder system which includes at least one wear-resistant additive which includes diamond particles dispersed therein. A surface covering includes a base layer, a wear-resistant layer, and optionally a topcoat layer. The wear-resistant layer is laminated to the base layer. The wear-resistant layer may be formed by dispersing a plurality of wear-resistant additive particles, which include diamonds, into a liquid to form a stable liquid dispersion, blending the stable liquid dispersion into a polymeric resin to form a mixture, and extruding the mixture to form the wear layer. La présente invention concerne une composition résistante à l'usure qui comprend un système de liant polymère thermofusible qui comprend au moins un additif résistant à l'usure qui comprend des particules de diamant dispersées en son sein. Un revêtement de surface comprend une couche de base, une couche résistante à l'usure, et éventuellement une couche de finition. La couche résistante à l'usure est stratifiée sur la couche de base. La couche résistante à l'usure peut être formée en dispersant une pluralité de particules d'additifs résistants à l'usure, qui comprennent des diamants, dans un liquide pour former une dispersion liquide stable, en mélangeant la dispersion liquide stable dans une résine polymère pour former un mélange, et en extrudant le mélange pour former la couche d'usure.
