COMPOSITE STONE SURFACING WITH IMPROVED OPTICAL AND WEAR RESISTANCE PROPERTIES

WIPO Patent Application WO2001030719

A3

A decorative composite stone material, the finished face of which is more durable and requires less maintenance than previous composite stone products. The decorative component of the aggregate material is specifically limited to a hard aggregate of enhanced aesthetic appeal, specifically, to granules of quartz or other transparent or semi-transparent material (20) having a Mohs index of at least 7, naturally occurring or synthetic. The granules of quartz are adjustably coated with a metallic, ceramic, plastic or other film, mixed with a binder (30), cast, and cured. In the surface finishing step, granules close to the surface are ground to create an exposed face (42) through which light passes in and out, the coating (24) providing reflective properties that add color, sparkle, glitter, metallic or other visual effect to the hard composite stone surface without compromising the hardness and durability of the product.
