Problems solved by technology

Because the reflective luminous pavement markers are made by simple physical mixing of the above-mentioned raw materials, the glass beads, luminous powder and luminous powder still maintain the original state. In the natural state, the glass beads are easy to absorb dust, and In rainy and foggy weather, a layer of water film will be adsorbed on the surface, 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 hydrolyze, easy to lose its luminescent properties

Embodiment 1

[0016] Heat 100 grams of quartz sand with a particle size of 0.2-0.4mm to 100°C, and then add the pre-mixed mixture of the following materials, which is 4.6 grams of hydrogenated bisphenol A epoxy resin and 1 gram of particle size of 0.1mm ZnS:Eu 2+ Luminous material, stir evenly after adding. After the temperature is lowered, it is crushed and sieved to obtain granular material A whose surface is coated with a luminous layer on the quartz sand. In this process, fluorosilane is added to carry out hydrophobic modification on the hydrogenated bisphenol A epoxy resin, so that the cured material A is hydrophobic. Put the obtained material into a mold and form it into a luminescent brick, and its initial brightness is 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

[0018] Heat 10kg of quartz sand with a particle size of 0.07-0.2mm to 200°C, and then add the pre-mixed mixture of the following materials, the mixture is 100 grams of acrylic resin, 600 grams of CaSrS:Eu with a particle size of 0.0080mm 2+ , Dy 3+ Luminescent material, 100 grams of reflective glass beads and 3 grams of silane coupling agent 550 are added and stirred evenly. After the temperature is lowered, it is crushed and sieved to obtain granular material B whose surface is covered with a luminous and reflective layer on the quartz sand. In this process, phenylmethyl silicone oil is introduced to carry out hydrophobic treatment on the acrylic resin, so that the cured material B has strong hydrophobicity. Put the obtained material into a mold and form it into a luminescent brick, and its initial brightness is 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 m...

Embodiment 3

[0020] Take 10kg of quartz sand with a particle size of 0.2-0.4mm, heat it to 260°C, and then add the pre-mixed mixture of the following materials, which is 600 grams of 70% 650 polyester solution and 560 grams of 75% HDI Biuret solution, 5 grams of silane coupling agent 550, 0.6 grams of light stabilizer UV-327, 0.9 grams of antioxidant 1222, 1.8 grams of zinc naphthenate, trimethylolpropane 20 as chain extender and crosslinking agent g, 15 g of methyl ethyl ketone as a urethane grade solvent, SrAl with a particle size of 0.1 mm 2 o 4 :Eu 2+ , Dy 3+ Add 500 grams of luminescent material, stir evenly after adding, crush and sieve after the temperature drops, and then obtain granular material C with a luminescent layer coated on the surface of quartz sand. In this process, polyphenylene ether resin is added to carry out hydrophobic treatment on the polyester solution, so that the cured material C has strong hydrophobicity. Put the obtained material into a mold and form it i...

Abstract

The invention relates to a hydrophobing luminous particle which comprises a skeletal material and a luminous layer and / or a reflecting layer coated on the skeletal material. The luminous layer and / or the reflecting layer is composed of a bonding agent and a luminous material and / or a reflecting material mixed in the bonding agent. The bonding agent has certain hydrophobing property. The hydrophobing luminous particle can be used for manufacturing a luminous brick and a luminous sign or for laying a road surface to form a luminous road surface and the like. The hydrophobing luminous particle and a product thereof have excellent wear resisting property and good luminous performance.

Description

technical field [0001] The invention relates to a luminescent particle, in particular to a hydrophobic particle which reflects light and / or absorbs light, stores light energy and emits light continuously for a long time, and a preparation method and application of the particle, belonging to the field of building decoration materials. Background technique [0002] Luminescent and reflective materials are widely used in daily life, such as in electronic appliances, commercial places, civil facilities, construction, communications, textiles, building materials, mining, machinery, railways, ships, aviation, hospitals, advertising and other fields.
