Microcrystalline jade and preparation method thereof

Abstract

The invention provides a microcrystalline jade and a preparation method thereof, wherein the microcrystalline jade comprises main components, auxiliary components and coloring agent, wherein the main components comprise SiO2, CaO, R2O, F<-> and Al2O3 and account for 80.0-95.0 percent of the total weight; the auxiliary components comprise ZnO, MgO, TiO2, B2O3, P2O5 and Cl<->, and account for 5.0-15.0 percent of the total weight; and the coloring agent accounts for 0-5.0 percent of the total weight. The preparation method of the microcrystalline jade comprises the following steps of: first, evenly mixing raw materials of the chemical composition of the microcrystalline jade; then, putting the raw materials into a high temperature smelting furnace to be molten into glass liquid, and molding the glass liquid into a basic glass plate or a special section block by a molding technique; and finally, carrying out crystallization or annealing heat treatment on the basic glass plate or the special section block, and forming the microcrystalline jade. The microcrystalline jade is in a semi-transparent wax-lipid shape, is fine and smooth in texture as well as crystal clear, can be widely used as a decorating plate, and can be also processed into artware, tableware or sanitary ware.

Description

technical field [0001] The invention relates to a microcrystalline jade and a preparation method thereof, belonging to the technical field of glass ceramics. Background technique [0002] With the gradual reduction of natural jade resources, artificial jade has attracted much attention. At present, there are mainly four types of artificial jade, which are: (1) Plastic artificial jade synthesized by resin and other fillers. This kind of jade is mainly composed of resin, curing agent and filler. Its color is natural and diverse, elegant and beautiful. , high toughness, but this kind of plastic jade has poor wear resistance, corrosion resistance and temperature resistance, and it is not anti-aging and lacks the texture of natural jade; (2) Air-hardening magnesia gelling material, this material is mainly Using magnesium oxide, magnesium chloride, glass fiber and other auxiliary materials as raw materials, it is made by mixing raw materials and air-hardening.

Problems solved by technology

At present, there are mainly four types of artificial jade, which are: (1) Plastic artificial jade synthesized by resin and other fillers. This kind of jade is mainly composed of resin, curing agent and filler. Its color is natural and diverse, elegant and beautiful. , high toughness, but this kind of plastic jade has poor wear resistance, corrosion resistance and temperature resistance, and it is not anti-aging and lacks the texture of natural jade; (2) Air-hardening magnesia gelling material, this material is mainly Using magnesium oxide, magnesium chloride, glass fiber and other auxiliary materials as raw materials, it is made by mixing raw materials and air-hardening. Its surface is smooth, wear-resistant, hard as jade, low in cost, and simple in production technology. The quality of the material is unstable during use, and it is prone to warping and deformation, absorbing moisture and returning to halogen, and whitening, which seriously affects its use and appearance; (3) the composite material of adhesive and natural jade or glass, this kind of Jade materials are mainly made of resin or other adhesives and crushed natural jade or glass materials. Although the cost of this material is low and the process is simple, it is cured at room temperature, and its disadvantage is that it is not anti-aging. , low hardness, light weight, poor simulation

If high-temperature synthesis is used, the modeling range is limited, the production cycle is long, and the cost is high; (4) opalescent glass, this type of material is mainly made of ordinary glass, and then a certain amount of colorant and emulsifier are added to melt, shape, and emulsify. , Annealed and cut into finished products, which have the advantages of bright color, no deformation, and high gloss. However, opal glass is brittle and easy to break. There is no crystal structure inside, and the processing performance such as cutting and engraving is poor.
