Luminescent agglomerated stone material, manufacturing method and applications thereof

Abstract

The present disclosure relates to an agglomerated stone material exhibiting a luminescent effect under UV illumination. The composition comprises aggregates, fillers, a polymeric binder, and at least one luminescent agent, which is present in an amount ranging from 0.001% to 15% w/w, selected from optical brighteners, fluorescent pigments, or phosphorescent pigments. The disclosure also provides a manufacturing method, which includes mixing the aggregates, adding the polymeric binder, incorporating fillers and luminescent agents, distributing the mixture into a mold, compacting it by vacuum vibrocompression, curing the material, and optionally applying finishing treatments, wherein the luminescent agent is incorporated in its pure form or predispersed in aggregates, pigments or the polymeric binder. Finally, the disclosure refers to the use of the agglomerated stone material in architectural or decorative surfaces, signage or information displays or safety markers and wayfinding systems.
