Problems solved by technology

Because the glass beads, luminescent powder and luminous powder used as luminescent materials in the reflective luminous pavement markers are exposed in the air, the glass beads are easy to absorb dust, and a layer of water film will be absorbed on the surface in rainy and foggy weather, which will Seriously affect its reflective effect; luminous powder and luminous powder will lose their luminous properties due to hydrolysis if they are exposed to the air for a long time
In Chinese patent documents CN1414061A and CN1660712A, luminous and luminescent artificial stones and luminescent and luminescent stones are also disclosed respectively. However, these materials also have the above-mentioned problems, that is, the luminescent materials cannot be effectively protected. Easy to wear after use, easy to lose its luminous properties
In addition, these light-emitting building materials are not water-permeable

Abstract

The invention relates to light-emitting particles, the light-emitting particles comprise aggregates and light-emitting and / or reflective layers coated on the aggregates, wherein the light-emitting and / or reflective layers consist of bonding agents and light-emitting materials and / or reflective materials mixed in the bonding agents. The light-emitting particles can be used for manufacturing light-emitting water permeable bricks or be used for paving a pavement for forming the light-emitting water permeable pavement and the like. The light-emitting particles and products thereof have excellent water permeability, abrasion resistance and light-emitting performance.

Description

technical field [0001] The invention relates to a luminescent particle, in particular to a hydrophilic material that stores light energy after reflecting and / or absorbing light and continues to emit light for a long time and has hydrophilicity, a preparation method and application of the material, and belongs to the field of building decoration materials . Background technique [0002] At present, the lack of energy and water resources in the world, the expansion of desertification area and the frequent occurrence of sandstorms have made the living environment of human beings worse and worse. At present, the places where urban residents live are basically hardened ground paved with impermeable materials such as cement and asphalt. When it rains, the rainwater will flow away with the drainage pipes, which will increase the burden on urban drainage facilities. The recovery directly affects the health of urban vegetation, so the application of permeable materials was born. Fo...
