Abstract
The invention relates to the technical field of ceramic production, and provides a transparent frit and a preparation method thereof. The transparent frit has the advantages that the stability, the luster, and the brightness are high, and the quality of ceramic product is good. The transparent frit comprises the following components in parts by weight: 30 to 35 parts of borax, 20 to 25 parts of boric acid, 17 to 20 parts of quartz, 3 to 4 parts of niter, 2 to 3 parts of feldspar, 1.5 to 2 parts of limestone, 0.8 to 1 part of talcum, and 8 to 10 parts of kaolin.
Description
Technical field
The present invention relates to technical field of ceramic production, particularly to a kind of clear frit and preparation method thereof.
Background technology
Tradition frit is a kind of glass, is by certain raw material composition, is then quenched through high temperature melting and forms, and has a speciality such as insolubility, stability, polished imposes on various vessel, becomes the nature of glass of a thin layer after firing.Can be widely applied to architectural ceramics, household china, artistic porcelain etc..Fritted glaze is different according to its characteristic, it is possible to be divided into clear frit glaze, Creamy white frit glaze, leaded fritted glaze and lead-free fritting enamel.In melting process, there is granular and lamellar outward appearance because manufacture is different.Because fritted glaze has insolubility, so safety is high, can be used alone, it is possible to make an addition in general raw glaze and use as flux.
China is a pottery big country, also it is the leading exporter of pottery, country of consumption and manufacturing country in the world, the consumption of its frit is also very huge, the clear frit firing range used in the market is narrow, stability is not high, glossiness compares relatively low, especially for the fritted glaze making Noctilucent ceramics goods, Noctilucent material and frit and water are configured to luminous glaze poor stability, must using within depositing after being configured to luminous glaze 24 hours, standing time is short, poor stability, the product glossiness fired is partially dark, affects the quality of Noctilucent ceramics goods.
Summary of the invention
Therefore, for above-mentioned problem, the present invention proposes that a kind of stability height is good, gloss brightness high, clear frit that ceramic quality is high and preparation method thereof.
For realizing above-mentioned technical problem, the solution that the present invention takes is: a kind of clear frit, is prepared from including by following raw material, and the ratio of weight and number of each composition of described raw material is:
Borax 30-35 weight portion
Boric acid 20-25 weight portion
Quartz 17-20 weight portion
Sal Nitri 3-4 weight portion
Anhydrite 2-3 weight portion

Kaolin 8-10 weight portion.
Further, described raw material also includes:
Zinc oxide 0.8-1 weight portion
Strontium carbonate 8-10 weight portion
Magnesium carbonate 0.8-1 weight portion.
Further, described raw material also includes:
Brium carbonate 4-5 weight portion.
A kind of method preparing above-mentioned clear frit, comprises the following steps:
A. by each composition mix homogeneously by ratio of weight and the number of copies of raw material；It is then placed in Cinker clew furnace and refines, be completely melt to bubble-free through water-cooled but, then dry, obtain basis dispensing；
B. basic dispensing previous step baked puts into pulverizer and pulverizes, and fineness is to≤3.5 millimeters；
C. basic dispensing previous step crushed is ground, and crosses 180-300 mesh sieve, be finished product after grinding.
Further, in described step a, the smelting temperature of basis dispensing is 1150 DEG C-1350 DEG C.
Further, the basic dispensing crushed in described step c is ground in quickly mill, and milling time is 10-60 minute.
By adopting preceding solution, the invention has the beneficial effects as follows: the clear frit environmental protection of the present invention, radiationless and high brightness, it is constantly study down through inventor's last decade to develop, the features such as this product has lead-free and cadmium-free, light "dead", high, corrosion resistance is strong, stability is strong；Be especially applicable to configuration luminous glaze make Noctilucent ceramics goods aspect, the luminous glaze of its configuration can long-term storage and do not affect make Noctilucent ceramics goods quality；Strengthen the storing capacity of Noctilucent ceramics goods simultaneously, extend the giving out light the time of Noctilucent ceramics goods, can wide popularization and application in Production of Ceramics field.
