Problems solved by technology

The shortcoming that said technology exists is: first, directly use granite, quartz sand, marble, glass etc. Disadvantages; second, in the batching step, the aggregate is first mixed with light-storing and luminescent materials, and then the process of adding adhesives, on the one hand, consumes more adhesives (the price of resin adhesives is relatively high, It largely determines the price of the manufactured product), on the other hand, the presence of light-storing and luminescent materials will also affect the bonding of the binder to the aggregate, thereby affecting the bonding between the binder and the bone. The binding force between the materials further affects the strength of the stone produced

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 ...

Abstract

The invention relates to a method for preparing light-emitting materials, which comprises the following steps: carrying out pre-film coating treatment on aggregates, then adding bonding agents and light-emitting materials and / or reflective materials, and evenly stirring, thereby obtaining the light-emitting materials. The light-emitting materials can be used for manufacturing light-emitting bricks or be used for paving a pavement for forming the light-emitting pavement and the like. The light-emitting materials and products thereof have excellent abrasion resistance and light-emitting performance.

Description

technical field [0001] The invention relates to a luminescent material, in particular to a preparation method of a material which reflects light and / or absorbs light and stores light energy and lasts for a long time to emit light. 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. [0003] Light-storing self-luminous materials are a new type of luminescent materials developed in the past two decades, and their application fields are now very extensive. They have been promoted and applied in the fields of fire protection, transportation, printing and dyeing, daily necessities, etc. Sign boards, luminous indicator lights, luminous guide signs, luminous paints, etc. At present, people are focusing more and more atten...
