Abstract
The present invention discloses a kind of preparation method of nuisanceless ceramic overglaze color flux, quartzy 19.1%, boric acid 47.7%, aluminium oxide 6.7%, lithium carbonate 7%, potassium nitrate 3%, sodium carbonate 8.4%, precipitated calcium carbonate 3.8%, niobium pentaoxide 3.5%, tantalum pentoxide 0.8% obtain ceramic overglaze color flux through ingredient, grinding, high temperature melting, Low Temperature Heat Treatment, natural cooling, ball milling, sieving, drying process.Using ceramic overglaze color flux prepared by this method, alkali resistance is excellent, dish-washing machine is suitble to use, and alkali resistance reaches the requirement of the resistance to machine testing standard fancy grade that washes the dishes of European Union, which can be obviously improved China's domestic ceramics quality, have a vast market foreground.
Description
Technical field
The invention belongs to inorganic non-metallic material (ceramics) fields, and in particular to a kind of system of nuisanceless ceramic overglaze color flux
Preparation 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, environmentally protective, the excellent nuisanceless pottery of alkali resistance
The preparation method of porcelain overglaze color flux.
The present invention is achieved by the following technical programs: a kind of preparation method of nuisanceless ceramic overglaze color flux,
It is characterized in that: the weight percent of material composition are as follows: quartzy 19.1%, boric acid 47.7%, aluminium oxide 6.7%, lithium carbonate 7%, nitric acid
Potassium 3%, sodium carbonate 8.4%, precipitated calcium carbonate 3.8%, niobium pentaoxide 3.5%, tantalum pentoxide 0.8%, through ingredient, grinding, high temperature
Melted, Low Temperature Heat Treatment, 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 1260 ~ 1280 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
Property excellent, the nuisanceless ceramic overglaze color flux that is suitble to dish-washing machine to use, alkali resistance reaches the resistance to machine testing standard that washes the dishes of European Union
The requirement of fancy grade, the flux can be obviously improved China's domestic ceramics quality, have significant economic benefit.
