Noctilucent artificial stone and preparation method thereof

Abstract

The invention discloses a noctilucent artificial stone and a preparation method thereof, belonging to the field of building decoration material. The noctilucent artificial stone contains, by weight percent, 0%-75% of inorganic filling, 20%-84% of unsaturated polyester resin or methacrylic acid type resin, 0%-6% of color paste, 0.5%-1.5% of coupling agent, 0.3%-20% of noctilucent material, 0.5%-11% of thermally expandable microcapsule, 0.5%-3% of nano titanium dioxide, accelerant which is 0.3%-2% of the content of the unsaturated polyester resin or methacrylic acid type resin, and curing agent which is 0.5%-3% of the content of the unsaturated polyester resin or methacrylic acid type resin. The nano titanium dioxide added to the artificial stone enables the surface of the artificial stone to have the functions of decomposing oil stains, removing bad smell, sterilizing and self-cleaning. Since the noctilucent material can absorb light and give out light naturally, the artificial stone can give out soft light at night. The specific gravity of the thermally expandable microcapsule is ultra-low, so the density of the artificial stone product can be greatly reduced.

Description

technical field [0001] The invention relates to a luminous artificial stone and a preparation method thereof, belonging to the field of building decoration materials. Background technique [0002] Under the circumstance that the worldwide environmental pollution problem has been paid more and more attention by the governments of various countries, the use of nano-materials for environmental governance has become a hot spot in the high-tech competition of various countries. In terms of nano-photocatalysis, Japan, the United States and other countries have invested heavily in research and development, and vigorously promoted its industrialization. At present, many products have appeared. Nano-TiO 2 High oxidation activity, good chemical stability, non-toxic to the human body, low cost, no pollution, wide application range, so it is the most valued and most promising green catalyst.

AI Technical Summary

Problems solved by technology

[0003] In the existing light-storing artificial stone products, the light-storage material is expensive, and has the disadvantages of short light-storage time, low light-storage intensity, and radioactivity in the light-storage material. Artificial stone products are mainly home decoration products, and the product is required to be non-radioactive, so Ordinary luminous artificial stone products have limitations

Moreover, the afterglow time of traditional light storage materials on the market is only 1 to 3 hours, and it is easy to deteriorate and turn black in strong light (such as sunlight), ultraviolet light and humid air.

The fillers used in existing artificial stone products are all inorganic minerals or ordinary stone powder, and their specific gravity is between 2.3-2.9, which leads to a high specific gravity of artificial stone products, about 1.5-1.9. The high density of the product will affect its decorative effect. Use in some fields, and increase the transportation cost of artificial stone products
