Embodiment 1
[0017] Take 100 grams of the pre-coated quartz sand with a particle size of 0.2-0.4 mm, and then add the pre-mixed mixture of the following materials. The mixture is 4.6 grams of hydrogenated bisphenol A epoxy resin with a particle size of 0.1 mm ZnS:Eu 2+ Add 1 g of luminescent material and stir evenly to obtain luminescent material A. Put the obtained luminescent material into a mold and form it into a luminescent brick with an initial brightness of 10cd / m 2 , 0.010cd / m after 10 hours 2 . ZnS in this embodiment:Eu 2+ The light-emitting material is a sulfide-based light-storage type self-luminous material.
Embodiment 2
[0019] Take 10 kg of the above-mentioned pre-coated quartz sand with a particle size of 0.4-0.8mm, and then add the mixture of the following materials that have been mixed in advance, the mixture is 100 grams of acrylic resin, 600 grams of CaSrS:Eu 2+ , Dy 3+ Luminescent material, 100 grams of reflective glass beads and 3 grams of silane coupling agent 550 were added and stirred evenly to obtain luminescent material B. Put the obtained luminescent material into a mold and form it into a luminescent brick with an initial brightness of 12cd / m 2 , 0.015cd / m after 10 hours 2 . CaSrS in this embodiment:Eu 2+ , Dy 3+ The light-emitting material is a sulfide-based light-storage type self-luminous material.
Embodiment 3
[0021] Take 10 kilograms of quartz sand with a particle size of 1.2-1.6 mm that has been pre-coated, add 0.18 kilograms of hydrogenated bisphenol A epoxy resin, 189 grams of aliphatic polyamine curing agent, and 1.98 grams of light stabilizer EPU. 1.98 grams of antioxidant 1035, after stirring well, add 600 grams of Sr with a particle size of 0.01mm 4 al 14 o 25 :Eu 2+ , Dy 3+ The luminescent material is continuously stirred until the materials are evenly mixed, and the luminescent material D is obtained. Choose a 1-square-meter road surface, lay a 20-centimeter stone base on the road surface and tamp it down, mix the above-mentioned luminous material D fully, lay it on the roadbed, compact and level it to form a 15-centimeter luminous road surface, and the road surface emits blue-green light , its initial brightness is 15cd / m 2 , 0.025cd / m after 10 hours 2 . Sr in this example 4 al 14 o 25 :Eu 2+ , Dy 3+ The luminescent material is an aluminate light storage type ...
