Abstract

The present invention provides a lead-free fritted glaze for high-grade household porcelain. Zirconium and litium fritted glaze with wide firing range and good brightness is used, and a large amount of borax is added in the composition, without poisonous minium constituents. The lead-free fritted glaze for high-grade household porcelain has the advantages of scientific and reasonable composition, easy operation, good adaptability of blank glaze, fine and smooth glaze, high brightness, good elasticity, high mechanical strength and good thermal shock stability, is suitable for various kinds of high-grade household porcelain blanks, and can satisfy the requirements of high-grade household porcelain. The lead-free fritted glaze has the lead release quantity of 0.000 ppm, and thoroughly avoids the problem that the lead glaze in porcelain has poison to human bodies.

Description

Lead-free fritting enamel for high-grade porcelain
The present invention relates to a kind of lead-free fritting enamel that is used on the high-grade porcelain.
At present, high-grade porcelain is the lead frit glaze with fritted glaze, make low temperature frit by red lead and borax, silicate minerals, other alkalimetal oxide, because the unique property of lead composition, make the lead frit glaze have characteristics such as fusibility, luminance brightness height, good springiness, physical strength are big, good thermal shock stability, therefore, for these years, the lead frit glaze is extensively being continued to use always.
Along with the continuous development of society, the improving constantly of living standards of the people plumbously caused people's great attention to the harm of human body.Lead composition continues or invades human body frequently, can cause polyneuritis, toxic encephalopthy etc.Stipulate in the GB12651-90 standard that the lead of the ceramic that contacts with food, quantity of cadmium release need less than 7ppm.Therefore, developing a kind of lead-free fritting enamel that can satisfy the high-grade porcelain requirement, is the great difficult problem that people press for solution, is the requirement in epoch.
The object of the present invention is to provide a kind of lead-free fritting enamel for high-grade porcelain, this glaze is formed scientific and reasonable, easy to implement, can satisfy the requirement of high-grade porcelain, has thoroughly exempted in the porcelain lead glaze to the murder by poisoning problem of human body.
Lead-free fritting enamel for high-grade porcelain of the present invention contains SiO 2, Al 2O 3, the weight percent of its its chemical constitution is:
SiO 2 50～70
Al 2O 3 9～14
B 2O 3 1～7
CaO 1～9
MgO 0～4
SrO 0～6
ZnO 0～5
K 2O 0～3
Na 2O 0～3
Li 2O 1～3
P 2O 5 0～6
ZrO 2 1～4
The lead-free fritting enamel for high-grade porcelain of above-mentioned composition, mainly formulated by frit and clay, wherein, the ingredients by weight percentage composition of frit is as follows, and not enough component is by corresponding raw material adjustment, as SiO in the glaze 2Amount by quartz adjustment etc.:
Quartzy 25.00～30.00 feldspars, 12.00～17.00 zircons, 5.00～7.00 boraxs, 13.00～17.00 clays, 12.00～16.00 lime carbonate, 0～8.00 rhombspar, 2.00～3.00 boric acid, 0.5～1 Strontium carbonate powder, 7.00～8.00 Quilonum Retards, 2.00～4.00 bone ashes, 3.00～5.00 zinc oxide 4.00～6.00.
The optimum proportion weight percent of frit consists of:
Quartzy 26.00 feldspars, 15.00 zircons, 6.00 boraxs, 13.34 Longyan clays, 13.00 lime carbonate, 7.00 rhombspars, 3.00 boric acid, 0.66 Strontium carbonate powder, 7.00 Quilonum Retards, 2.00 bone ashes, 3.00 zinc oxide 4.00.
Described lead-free fritting enamel for high-grade porcelain, the weight batching ratio of its glaze is: frit 80～90% quartz 0～10% clay 4～10% porcelain powder 0～16% rhombspar 0～4% Quilonum Retard 0～2% lime borate 0～6%.
Lead-free fritting enamel of the present invention has adopted zirconium, the lithium fritted glaze that firing range is wide, glossiness is good, has added relatively large borax in the composition, in order to improve glaze gloss and temperature flowing, has added a spot of strong fusing assistant.
Frit need be at first made in the glaze preparation, and then the preparation glaze.The selection of raw material, use are with common identical, and the raw materials used composition of the present invention sees Table 1.
The first step: with frit raw material proportion ingredient on request, conventional preparation technology prepares frit, 1200～1300 ℃ of melt temperatures by frit.It is standby that frit is pulverized the back.
Second step: frit powder and all the other fecula material are mixed, cooperate preparation glaze such as water reducer, can directly pulverize in ball mill and make standby glaze slip, it is 0.02～0.05% that the glaze slip fineness is controlled at 10000-hole sieve surplus.
Glaze of the present invention high-grade porcelain manufacturing technique requirent and rules use routinely gets final product, and carries out conventional glazing, burns till, and gets finished product.The suitable firing temperature of this leadless glaze is 1160～1200 ℃.
Lead-free fritting enamel for high-grade porcelain of the present invention is formed scientific and reasonablely, easy to implement, and the base glaze adapts to, and is adapted to multiple high-grade porcelain base substrate, as quartz enriched porcelain, high feldspathic porcelain, bone china, steatite ceramic or the like, can satisfy the requirement of high-grade porcelain.Glaze is moist, the luminance brightness height, and transparency is good, good springiness, physical strength is big, and good thermal shock stability, lead release are 0.00ppm, have thoroughly exempted in the porcelain lead glaze to the murder by poisoning problem of human body.
The present invention is further illustrated below in conjunction with embodiment.
