Abstract

The invention provides a fluorescent glaze and a preparation method thereof. The fluorescent glaze is mainly prepared from the following raw materials by weight percentage: 50%-70% of glass frit, 20%-40% of feldspar and 2%-15% of calcined kaolin. The preparation method comprises the following steps of: firstly, mixing feldspar, calcium carbonate, barium carbonate, zinc oxide, aluminium oxide, borax, boric acid, quartz, strontium carbonate, vanadium pentoxide and bismuth oxide together in a certain weight ratio and then smelting the mixture at a temperature in the range from 1250 to 1350 DEG C; secondly, forming the glass frit after water quenching; and then enabling the glass frit to be subjected to coarse crushing, fine crushing and dosing grinding orderly, and mixing the ground powder with the feldspar and the calcined kaolin proportionally through a ball mill and grinding evenly, thereby obtaining the fluorescent glaze. The fluorescent glaze provided by the invention is free of rare-earth element, and can be excited under either natural light or a fluorescent lamp; the fluorescent glaze is high in fluorescent brightness and has persistence as long as 1300 min; the process of the preparation method of the fluorescent glaze is simple and capable of well meeting common requirements of the building ceramic industry.

Description

A kind of Fluorescent glaze and preparation method thereof

Technical field

The present invention relates to construction sanitary ceramic decoration technique field, what be specifically related to is composition of a kind of Fluorescent glaze and preparation method thereof.

Background technology

The research history of embedded photoluminescent material is very long, can trace back to Frenchman Sidot in 1866 the earliest and prepare the long after glow luminous material that first tool have significant practical applications .On this basis, people develop again , and etc. the better afterglowing material of performance.But sulfide material is very unstable, shortcoming is many, and as photostabilization is poor, wet fastness is poor, and time of persistence is short.In recent years, the materials such as rear-earth-doped aluminate by large quantity research, as with doping , , .The advantages such as it is high that it has luminous efficiency, and time of persistence is long, "dead" harm, are widely used in all many-sides such as night emergent instruction, photoelectron element, instrument display, low-light level illumination, have broad application prospects.In building material field, it can be used to produce the Fluorescent glaze with fluorescent effect, as the patent No.: 99123083.3, patent name is luminescent glaze, technology disclosed in it mainly uses the rare earth doping fluorescent body material mixing of parent glaze and synthesis to process, the advantages such as it is high that it has luminous intensity, good stability; In recent years, along with the minimizing of China rare earth resource and sharp rising of rare earth material price, the cost of rare earth material is used also significantly to rise in building material field; In addition, because the condition of synthesizing this fluor is higher, technique is also comparatively complicated; Therefore, develop a kind of technique simple, not containing the fluorescence glaze of rare earth, tool is of great significance.

Summary of the invention

The object of the invention is to solve the problems of the prior art, and provide a kind of technique simply, not to contain rare earth and the good Fluorescent glaze of twilight sunset effect and preparation method thereof.

The technical solution adopted in the present invention is such: a kind of Fluorescent glaze, and the raw material primarily of following weight percents is made: glass frit 50% ~ 70%, feldspar 20% ~ 40%, calcined kaolin 2% ~ 15%.The chemical composition of described Fluorescent glaze is composed as follows:

: 0.40 ~ 0.60 mole; : 0.3 ~ 0.6 mole;

: 0.05 ~ 0.20 mole; : 0.40 ~ 1.0 mole;

: 0.01 ~ 0.05 mole; : 0.05 ~ 0.20 mole;

: 3.0 ~ 6.0 moles; : 0.01 ~ 0.15 mole.

Preferably, the chemical composition of described glass frit consists of:

: 0.15 ~ 0.30 mole; : 0.4 ~ 0.8 mole;

: 0.05 ~ 0.12 mole; : 0.15 ~ 0.30 mole;

: 0.01 ~ 0.10 mole; : 0.05 ~ 0.20 mole;

: 3.0 ~ 5.0 moles; : 0.01 ~ 0.15 mole;

Wherein said for , and in the combination of one or more; Described for , and in the combination of one or more.Described feldspar is a kind of in albite, potassium felspar sand or both mixtures.

The preparation method of a kind of Fluorescent glaze of the present invention, comprises the following steps:

(1) be, feldspar 20% ~ 38% by weight percent, calcium carbonate 2% ~ 15%, barium carbonate 3% ~ 12%, zinc oxide 0.9% ~ 3.6%, aluminum oxide 0.2% ~ 0.8%, borax 1.5% ~ 6.6%, boric acid 4.4% ~ 18%, quartz 18% ~ 60%, Strontium carbonate powder 2% ~ 10%, Vanadium Pentoxide in FLAKES 0.5% ~ 3%, bismuth oxide 0.5% ~ 3%, founds, then forms glass frit after shrend at temperature 1250 DEG C ~ 1350 DEG C, by glass frit more successively through coarse crushing, in small, broken bits, batching grinding, the glass frit fineness of powder after grinding is for be less than 0.2% through 300 screen residues;

(2) be, by weight percent feldspar 20% ~ 40%, the glass frit powder 50% ~ 70% in calcined kaolin 2% ~ 15% and step (1), carry out mixed grinding through ball mill even, obtaining powder fineness is the Fluorescent glaze that 10000-hole sieve excess is less than 2%.
