Problems solved by technology

(1) Irradiation degradation: refers to the phenomenon that the phosphor powder is bombarded by high-energy rays or particles during use, and the internal structure, that is, the microenvironment of the luminescence center, changes, resulting in the degradation of phosphor performance, specifically manifested as brightness attenuation, chromaticity Offset, etc., leading to the attenuation of the life of the application object
(2) Thermal deterioration: After high-temperature baking or calcination process, the luminescent center of some phosphors is oxidized or microstructure changes, which will also cause deterioration of phosphor performance, which also manifests as brightness attenuation, chromaticity shift, etc. , which reduces the performance of phosphor products and limits the application range of phosphor
[0006] High-temperature calcination is required in the preparation process of artificial quartz stone, so there are technical defects in the prior art that fluorescent quartz stone does not emit enough light or cannot be produced

Embodiment 1

[0037] Preparation of silica-coated phosphor powder:

[0038] Dissolve 5.357g of tetraethyl orthosilicate in 300ml of water: ethanol with a volume ratio of 1:1, and stir to dissolve it. Adjust the pH value to 1 with nitric acid, and then adjust the pH value to 6 with ammonia water.

[0039] Add 11.3584g of urea and 30g of easily hydrolyzed blue long-lasting phosphor, react at 95°C for 1 hour under constant stirring, and the pH value is 8 at this time. The reaction system was cooled to room temperature, separated by suction filtration, washed twice with distilled water and ethanol, and then dried overnight at 80°C.

[0040] Dry the powder at 500°C, 20% H 2 / 80%N 2 The silicon oxide-coated green fluorescent powder was obtained by keeping it warm for 3 hours in a reducing atmosphere, and its luminous performance and afterglow performance had no obvious loss compared with the uncoated fluorescent powder.

Embodiment 2

[0042] 1) Ingredients, the raw material formula is: by mass parts: 65 parts of 0.075-5mm quartz granule raw material, 55 parts of 0.075-5mm granule raw material, 30 parts of 0.005-0.045mm quartz powder; 15 parts of polyurethane resin; vinyl triethoxy 0.15 part of silane; 0.15 part of dibenzoyl peroxide; 1 part of green fluorescent powder prepared in Example 1 is prepared and weighed according to the formula;

[0043] 2) Stirring, the stirring process is relatively simple, just mix the raw materials such as resin, coupling agent, curing agent and fluorescent coloring material prepared in proportion in a special mixing tank and stir until it is evenly stirred;

[0044]3) Fabric, spread a layer of kraft paper or silicone skin with the same specifications as the mold on the conveyor belt, place the mold on the laid kraft paper, put 4 strips of kraft paper inside the four sides of the mold, and then put 4 strips of silicone, The height should be 3mm higher than the mold plate, fold...

Abstract

The invention relates to a fluorescent artificial quartz stone plate and a preparation method thereof. Inorganic oxide coated phosphor powder is used as a fluorescent filler, so as to inhibit the hydrolysis of the phosphor powder during the preparation of quartz stones. A coating layer is uniform, continuous, compact, firm and thin and reduces the loss of luminous intensity. The artificial quartz stones prepared by the method have the advantages of beautiful appearance, bright patterns and unique colors, greatly enrich the varieties and patterns of the artificial quartz stones, can be used for a variety of decorative occasions, and have a wide scope of application.

Description

technical field [0001] The invention relates to an artificial quartz stone plate and a preparation method thereof, in particular to a fluorescent artificial quartz stone plate and a preparation method thereof. Background technique [0002] Artificial stone is a new type of non-radioactive, non-polluting, reusable, green and environmentally friendly building interior decoration material. As a new strategic health and environmental protection product in line with the country's sustainable development, it was introduced into the domestic market in the 1980s. The artificial stones currently on the market are mainly organic artificial stones with polymer resin materials as adhesives, which are divided into three categories: artificial marble (hereinafter referred to as artificial granite), artificial quartz stone and acrylic. Although my country's artificial stone industry started late, after more than ten years of rapid development, it ranks among the top in the world in terms ...
