Description

The preparation method of flux on a kind of alkali resistance ceramic glaze

Technical field

The invention belongs to inorganic non-metallic material (ceramics) fields, and in particular to the preparation of flux on a kind of alkali resistance ceramic glaze Method.

Background technique

In recent years, the rhythm of life accelerated with the increasing living standard of people and constantly, the service such as food and drink, tourism Industry also get up therewith by rapid development, and more and more food and beverage enterprises even average family starts that dish-washing machine is selected to eat domestic ceramics Tool etc. is cleaned.But for the cleaning solution used in the dish-washing machine, wherein the alkaline auxiliary lotion contained, defoaming agent, oxidant, Surfactant and thickener etc. have very strong corrosivity for Conventional Portland product, especially make pottery to traditional overglaze color Ceramic products have stronger corrosiveness, and the overglaze color pottery after dish-washing machine cleans for a long time is easy to produce permanent surface Damage, such as colour fading, white opacity, iridescence, corrosion trace, have seriously affected their reuse, have improved use cost.

In addition, European Union is more and more harsher for the examination criteria of pottery machine washable, China's overglaze color is caused to be decorated Tableware for daily use, hotel porcelain etc. are difficult to up to standard, thus can not be successfully export sales, bring to China's domestic ceramics industry very big Impact.Important component of the flux as ceramic overglaze color, influence corrosion proof for ornament materials on glaze is to Guan Chong It wants.

Ceramic decoration material refers to the materials such as all kinds of pigment for decorating ceramic articles, decal paper, wherein on glaze Based on decorative pigment.However ceramic glazing dyestuff is mainly formulated by a large amount of flux and a certain amount of colorant, it is traditional Decal paper is by various pigment according to made of specific color theory while the printing such as add black oil.The lead of ceramic decoration material The performances such as quantity of cadmium release, corrosion resistance depend primarily on the flux that content is up to 70% or more other than the performance of colorant itself, Therefore there is significant impact to performances such as corrosion resistances in flux.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of simple processes, alkali resistance environmentally protective, alkali resistance is excellent The preparation method of flux on ceramic glaze.

The present invention is achieved by the following technical programs: the preparation method of flux on a kind of alkali resistance ceramic glaze.

, it is characterised in that: according to chemical composition percentage: SiO₂ 24~40%、B₂O₃ 36~44%、 Al₂O₃ 16~24%、 Li₂O 2~6%、KNaO 2~7%、CaO 2~8%、Nb₂O₅ 1~5%、Ta₂O₅1 ~ 5%, through ingredient, grinding, high temperature melting, Low Temperature Thermal Processing, natural cooling, ball milling, sieving, drying process obtain flux on ceramic glaze.

The parameter of the high temperature melting process are as follows: heating rate is 5 DEG C/min, and highest glass melting temperature is 1360 ~ 1390 DEG C, Soaking time is 60min.

The Low Temperature Heat Treatment process are as follows: the melt after high temperature melting is poured into the steel tank for being preheated to 600 DEG C, then passed through 10 ~ 100h is warming up to 700 DEG C.

The sieving process are as follows: cross 380 meshes, tailing over is 0.

The present invention utilizes the high boron system of high alumina, composite transition metal oxide and special heat treating regime, is made alkaline-resisting The preparation method of flux, alkali resistance reach the resistance to machine testing standard fancy grade that washes the dishes of European Union on the excellent alkali resistance ceramic glaze of property It is required that the flux can be obviously improved China's domestic ceramics quality, there is significant economic benefit.
