Abstract

The invention discloses a lead-free and cadmium -free bone china glaze and a preparation process thereof. The lead-free and cadmium-free bone china glaze comprises the following compositions in percentage by weight: 50.0 to 62.0 percent of SiO2, 6.0 to 10.0 percent of Al2O3, 6.0 to 10.0 percent of CaO, 0.5 to 4 percent of MgO, 0.0 to 2.0 percent of BaO, 0.5 to 3.0 percent of SrO, 6.0 to 10.0 percent of ZnO, 2.0 to 6.5 percent of K2O, 1.0 to 5.0 percent of Na2O, 0.2 to 3.0 percent of Li2O, 1.0 to 3.0 percent of B2O3, 1.0 to 3.5 percent of ZrO2, 0.2 to 1.0 percent of La2O3, and 0.1 to 2.0 percent of P2O5. By optimizing the glaze formula, the glaze has no lead and cadmium, so the glaze is non-toxic and environment-friendly. The lead-free and cadmium-free bone china glaze and the preparation process thereof have the advantages of reducing the consumption of zinc oxide, overcoming the defects of soft glaze, easy scratching and color disadvantage caused by high zinc oxide content, and improving the hardness of the glaze by optimizing the chemical compositions of the glaze.

Description

A kind of lead-free and cadmium-free bone china glaze and preparation technology thereof
Technical field
The invention belongs to the ceramic glaze technical field, especially relate to and a kind ofly can be used for the lead-free and cadmium-free bone china glaze in high-grade domestic ceramics field and the preparation technology of this bone china glaze thereof.
Background technology
Ceramic glaze has material impact to the visual appearance of ceramic.At present the most of ceramics of China have pore, bubble because of glaze, and surface gloss difference and cause product specification not high is of poor quality.The higher high-grade ceramic goods of some appearance requirement adopt the leaded glaze that fusing point is low, Young's modulus is big, glossiness is high mostly.Yet lead is heavy metal element, all is deleterious to human body and environment.Along with the raising of people to the deep and environmental consciousness of lead and compound understanding thereof, there is more and more stricter restriction various countries to the content and the use thereof of lead.
Summary of the invention
One of purpose of the present invention is to provide a kind of glaze formula, introduces rare earth compound in prescription, makes its lead-free and cadmium-free bone china glaze with rational chemical constitution and better physical performance index, solves the defective that prior art exists.
For achieving the above object, the present invention adopts following technical scheme: SiO 250.0~62.0%, Al 2O 36.0~10.0%, CaO 6.0~10.0%, MgO 0.5~4%, and BaO 0.0~2.0%, and SrO 0.5~3.0%, and ZnO 6.0~11.0%, K 2O 2.0~6.5%, Na 2O 1.0~5.0%, Li 2O 0.2~3.0%, B 2O 31.0~3.0%, ZrO 21.0~3.5%, La 2O 30.2~1.0%, P 2O 50.1~2.0%; Described each component sum is 100%.
A kind of lead-free and cadmium-free bone china glaze comprises following component and content (weight percentage): preferably: comprise component and content (weight percentage): SiO 253.0~56.0%, Al 2O 37.0~8.5%, CaO8.0~9.5%, MgO 2.0~3.0%, BaO0.5~1.0%, SrO1.5~2.0%, ZnO8.0~9.0%, K 2O4.0~5.5%, Na 2O 3.0~4.5%, Li 2O 2.0~3.0%, B 2O 31.0~2.0%, ZrO 22.0~3.0%, La 2O 30.3~0.8%, P 2O 50.5~1.5%.
Another object of the present invention is to provide a kind of preparation technology of lead-free and cadmium-free bone china glaze, comprise step:
A) get the silica powder 25.0~45.0% (weight percentage) that 200 orders or thinner mesh screen sieve, get the feldspar in powder 20.0~40.0% that 200 orders or thinner mesh screen sieve, borax 2.0~20.0%, zinc oxide 6.0~12.0%, zirconium silicate 2.0~5.0%, lanthanum trioxide 0.1~3.0%, lime carbonate 10.0~18.0%, magnesiumcarbonate 1.0~8.0%, barium carbonate 0.0~5.0%, Strontium carbonate powder 1.0~6.0%, Quilonum Retard 2.0~10.0%, Vanadium Pentoxide in FLAKES 0.1~3.0% is after above-mentioned raw materials mixed, 1380 ℃~1450 ℃ fusings, put into the cold water shrend and make frit;
B) frit is packed in the ball mill, the kaolin or other glaze slip properties modifier that add water and 2~10% grind to form glaze slip, and it is surplus less than 0.03% that fineness is controlled at 10000-hole sieve, makes lead-free and cadmium-free bone china glaze.
Preferably: step B) described other glaze slip properties modifier comprises polyvinyl alcohol or ammonium chloride.
More excellent is: the lead-free and cadmium-free bone china glaze firing temperature that described step B) makes is 1050 ℃~1180 ℃.
The present invention compared with prior art has following advantage and beneficial effect:
The present invention is by optimizing glaze formula, not leaded and cadmium in the glaze, nontoxic environmental protection.By optimizing the glaze chemical ingredients, reduced the usage quantity of zinc oxide, it is thin-skinned to have overcome the glaze that causes because of the zinc oxide content height, easily is scratched, and to the disadvantageous shortcoming of colour generation, has improved hardness of glaze surface.Taken into account applicable performance,, widened the firing range of glaze, made the product color development more saturated, thereby the high-temperature viscosity that lowers glaze improves the Gloss of Glazes degree by introducing rare earth compound lanthanum oxide and Vanadium Pentoxide in FLAKES to various colorant colour generations.An amount of introducing Vanadium Pentoxide in FLAKES makes the performance of glaze and china blank more approaching, increase the bonding properties of base glaze, improved the ability of the anti-rapid heat cycle of product, overcome because of the glaze firing narrow range, and underburnt that causes and burning defective, make the more apparent top grade of china finished product, improved the qualification rate of product.The ceramic hardness of glaze surface height that uses glaze of the present invention to produce, anti-delineation hinder that ability is strong, and glossiness is good, and color is pure, has improved the quality and the class of product.
