Abstract
A granulate made of a cured mixture comprising a transparent true light matrix in which at least one photoluminescent luminous pigment and a transparent filler material are present, wherein the filler material comprises a grain size of less than 30μ and/or a grain size between 70μ and 1.2 mm. The granulate may be produced by producing a hardenable binder mixture, introducing and mixing a photoluminescent luminous pigment into the hardenable binder mixture, dispersing a filler in the mixture, and milling the hardened mixture to form the granulate.
Claims29
Granulate comprising a hardened mixture that includes a transparent, light-fast matrix that contains at least one photoluminescent luminous pigment and one transparent filler, wherein the filler has an average particle size of less than 30μ and/or an average particle size between 70μ and 1.2 mm, and wherein the filler is coated with an adhesion promoter adapted to the matrix.
A material including a photoluminescent aggregate comprising a granulate, said granulate comprising a hardened mixture that includes a transparent, light-fast matrix that contains at least one photoluminescent luminous pigment and one transparent filler, wherein the filler has an average particle size of less than 30μ and/or an average particle size between 70μ and 1.2 mm, and wherein the filler is coated with an adhesion promoter adapted to the matrix, and wherein said material comprises at least one of a mineral material plate, mineral material object, engineered stone plates, engineered stone objects, solid surface plate, solid surface objects, concrete part, plaster, resin object, or a material having a surface with said granulate embedded therein.
Granulate comprising a hardened mixture that includes a transparent, light-fast matrix that contains at least one photoluminescent luminous pigment and one transparent filler, wherein the filler has an average particle size of less than 30μ and/or an average particle size between 70μ and 1.2 mm, and wherein the filler is coated with a silane.
