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

Abstract

The invention relates to an overlength afterglow luminescent glass particle. The particle is characterized by comprising transparent colorless glass particle aggregate, a resin layer and a luminescent powder layer. The resin layer is wrapped on the outer surface of the transparent colorless glass particle aggregate, and the luminescent powder layer is wrapped on the outer surface of the resin layer. The preparation method includes weighing 0.3-1.0 part of unsaturated polyester resin, adding 0.4-1.2 part of methyl ethyl ketone peroxide and 0.4-0.5 part of coupling reagent under the temperature of 60 DEG C to 80 DEG C, conducting solidification under normal temperature, then adding 0.2-1.5 part of cobalt iso-octoate, conducting stirring for 20 minutes for standby application, placing 1000-10000 parts of transparent colorless glass particle, taking 0.2-1.5 part of stirred resin, evenly stirring the resin, weighing 600-800 parts of luminescent powder and completely and evenly stirring the glass particle and the luminescent powder. The particle has the advantages of being good in hydrophily, abrasion resistance and luminescence performance and various in color. Other colors can be mixed according to requirements.

Description

technical field [0001] The invention belongs to building materials, in particular to an ultra-long afterglow luminescent glass particle and a preparation method thereof. Background technique [0002] In recent years, the application fields of light-storing self-luminous materials are very wide, and have been promoted and applied in the fields of fire protection, transportation, printing and dyeing, daily necessities, etc. . People are also increasingly applying light-storing self-luminous materials to the manufacture of luminous building materials. For example, in the Chinese patent document application number: 93106311.6, a reflective luminous pavement marker is disclosed, which is mainly composed of wear-resistant aggregates, powders, Reflective luminous material (glass beads, luminescent powder and luminous powder:), adhesive and curing agent, the road marking stone formed by this road marking material can be directly applied on the road surface, and the dust on the road...
