Three-color energy-storage luminescent composite wood-grain stone material

Abstract

The invention belongs to the technology of processing of artificial stone materials and especially relates to a colorized three-color energy-storage luminescent composite wood-grain stone material and a preparation method of the same. The stone material includes following components, by weight: 4.5-7% of glass sand (which is granules after glass waste materials crushed), 12.5-15.5% of epoxy resin, 0.26-0.65% of a curing agent, 0.3-0.7% of a coupling agent, 4-6% of luminescent stone powder comprising three colors, wherein each color accounts for 1 / 3 of the total amount, 1.5-2.5% of titanium dioxide and the balance being a wood-grain stone waste material, wherein the granularity distribution of the glass sand is 2-70 meshes and the granularity distribution of the wood-grain stone waste material is 4-325 meshes. The cured moulded stone material is dried at 65-80 DEG C. The stone material is good in night luminescent effect, is high in strength, is colorful, is free or radiation pollution and is low in production cost.

Description

technical field [0001] The invention belongs to the processing technology of artificial stone, in particular to a colored luminescent composite wood-grain stone and a preparation method thereof. Background technique [0002] Wood grain stone is produced in the bottom of Cambrian system, which belongs to marine sediments, and is iron-rich argillaceous dolomite. High-quality sandstone has a compact structure, uniform particles, fine texture, high water absorption, and has the characteristics of sound insulation, moisture absorption, damage resistance, weathering resistance, fading resistance, insolubility in water, and no radioactivity. Wood grain stone has good ornamental value due to its powder crystal, fine crystal structure and pattern similar to wood texture. Therefore, it is often used in indoor and outdoor decoration, furniture, sculpture art, and garden building materials. It is a rare Class A stone. Wuding County, Yunnan Province is rich in wood-grained stone resour...

Problems solved by technology

At the same time, the generation of a large amount of waste will seriously restrict the development of wood grain stone industry

[0003] Although there are related technologies of artificial stone in the prior art, such as "a method for making artificial marble" (patent application number: 200910192348.4), which can make use of waste stone and solve the problem of waste of resources, artificial marble has strength Low, radioactive pollution, and poor aesthetics for viewing at night, so the usage has been shrinking, lacking development prospects

[0004] Literature Chinese patent literature "Yingming Marble Pattern Decorative Board" (Application No.: 87200699) discloses a stone material with ornamental value at night, but it is based on a prefabricated concrete board, which is layered and compounded with luminescent powder And resin, because this kind of board adopts the method of layered processing, the process is complicated, the product cost is high, the strength of the material is low, and the texture and color are not bright enough.

[0005] The Chinese patent document "Energy Storage Luminous Composite Stone" (Application No.: 200510136868.5) discloses an artificial luminescent stone made of translucent marble mixed with resin. Increased manufacturing costs over the previous patent application

However, as mentioned in the article, the strength of natural marble is low. Although the strength can be increased by the amount of resin, the effect is limited; in addition, the light transmission of light-transmitting marble is not good enough, and the luminous effect of the finished product is not satisfactory. , but also lacks the beauty of color; marble has certain radioactive pollution, and this product should not be used in high-grade building materials
