Problems solved by technology

[0006] In addition, aiming at the shortcomings of the existing zirconium opacity glazes, which have many raw materials and high production costs, the present invention also provides two kinds of zirconium opacity glazes, both of which use zirconium-containing waste silica gel (abbreviated as waste silica gel, the same below) The residual zirconium is an opacifying agent, which not only solves the problem of waste silica gel storage and environmental pollution, but also reduces the types of raw materials used and reduces the production cost of opacifying glazes.

Embodiment 1

[0041] The frit is made from waste silica gel and soda ash, wherein the waste silica gel contains 5-12wt% zirconia and the rest is silica. In the raw materials, the amount of waste silica gel and soda ash meets the requirement of introducing SiO 2 and Na 2 The molar ratio of O is 75:25, which is 3:1. The frit is prepared as follows:

[0042] 1. Take waste silica gel and soda ash in proportion, mix them evenly, and heat them to 1280°C in an electric furnace or kiln to melt them;

[0043] 2. Quench the molten glass with water, filter it dry, and dry it at 120°C to obtain a frit. The resulting frit can be directly used as a raw material for producing water glass (commonly known as sodium silicate), and can also be used as a raw material for opacified glaze.

Embodiment 2

[0045] The frit is made from waste silica gel and soda ash, wherein the waste silica gel contains 5-12wt% zirconia and the rest is silica. In the raw materials, the amount of waste silica gel and soda ash meets the requirement of introducing SiO 2 and Na 2 The molar ratio of O is 67:33, except that waste silica gel and soda ash are heated to 1250° C. for melting, other steps for preparing frit are as in Example 1.

Embodiment 3

[0047] The opaque glaze is made from waste silica gel, soda ash, clay and albite, wherein the waste silica gel contains 5-12wt% zirconia and the rest is silica. In the raw materials, the amount of waste silica gel and soda ash meets the requirement of introducing SiO 2 and Na2 The molar ratio of O is 75:25, that is, 3:1, and the amount of clay is 1% of the total amount of frit, and the amount of albite is 5% of the total amount of waste silica gel and soda ash. Waste silica gel and soda ash are added in the form of frit, and the method for preparing frit glaze is as follows:

[0048] 1. Take waste silica gel and soda ash in proportion, mix them evenly, and heat them to 1280°C in an electric furnace or kiln to melt them;

[0049] 2. Quench the molten glass with water, filter it dry, and dry it at 120°C to obtain a frit;

[0050] 3. Mix the frit with clay and albite for ball milling (material: water: ball mass ratio is 1:0.7:1.5);

[0051] 4. Glaze the ceramic body by dipping...

Abstract

The invention discloses an alkali silicate glass frit, a zirconium frit opaque glaze, a zirconium raw material opaque glaze and a ceramic glazing method, wherein the main raw material of the frit glaze is a frit formed of waste silica gel and soda ash , wherein the amount of waste silica gel and soda ash meets the molar ratio of introduced SiO2 and Na2O of 2-3:1, while the raw glaze is directly pulped and fired by using waste silica gel and other raw materials. The opacifying glaze of the present invention uses zirconium-containing waste silica gel (abbreviated as waste silica gel, the same below) as raw materials, and uses the residual zirconium as an opacifying agent, which not only solves the problems of waste silica gel storage and environmental pollution, but also reduces the types of raw materials used , reduces the production cost of the opacity glaze, the waste silica gel in the preparation process can be used directly without physical and chemical treatment, which is convenient for industrial application, and the performance of the obtained opacity glaze can meet the general requirements.

Description

technical field [0001] The invention relates to an alkali silicate glass frit, an opaque glaze and a preparation method thereof, in particular to an alkali silicate glass frit, a zirconium opaque glaze and a preparation method thereof, and belongs to the technical field of inorganic non-metallic materials. Background technique [0002] Glass frits can be used to produce opacified glazes, and alkali silicate glass frits with sodium oxide and silicon dioxide as the main components are also raw materials for the production of water glass (common name: sodium silicate). Opaque glazes are widely used in the decoration of ceramics and enamel. The root of opacification is that the glassy glaze produces a second phase with a different refractive index from the matrix glass due to phase separation or crystallization, which causes light to pass through the glaze. It is caused by multiple refractions. Zirconium opacity glaze is one of the widely used opacity glazes, and its research h...
