Abstract
The invention discloses a lead-free ceramic glaze and a preparation method thereof. The glaze comprises the following components in parts by weight: 62 to 64 parts of SiO2, 7 parts of Al2O3, 5 parts of CaO, 3 to 4 parts of MgO, 4 parts of BaO, 3.5 to 4 parts of SrO, 7 to 8 parts of ZnO, 5.5 to 6 parts of K2O5, 4.5 to 4.8 parts of Na2O, 3.5 to 4.5 parts of Li2O3, 0.5 to 1.5 parts of Fe2O3, 6 to 7 parts of B2O3, 2.5 to 3.5 parts of ZrO2, and 1 to 2.5 parts of La2O3.
Description
Technical field
The present invention relates to lead-free ceramic glaze and preparation method thereof.
Background technology
Ceramic glaze is to the visual appearance important of ceramic.At present the most of ceramics of China have pore, bubble because of glaze, and surface gloss is poor and cause product specification not high, and is of poor quality.The high-grade ceramic goods that some appearance requirement are higher adopt the leaded glaze that fusing point is low, Young's modulus is large, glossiness is high mostly.Yet lead is heavy metal, and human body and environment are harmful to.Along with the raising of people to the deep and environmental consciousness of lead and toxicity of compound understanding thereof, there is more and more stricter restriction various countries to lead amount and use.
Although some lead-free ceramic glaze prescriptions that also occur in the existing ceramic glaze technology, these prescriptions are mainly used in high-end china basically, and the scope of use is subject to larger limitation.And the composition that contains Zn in the glaze is higher, there is larger negative impact in the color development such as black, the color and luster such as pink, coffee-like, thereby has limited the rich of product.Perhaps contain heavy metal Bi in some unleaded glaze
20
3, bismuth oxide and plumbous oxide belong to heavy metal together, have certain toxicity, and it are expensive.Existing leadless glaze material formula also exists the glaze firing scope all narrower, causes easily the defective of underburnt or burning.
Summary of the invention
Shortcoming for prior art the invention provides a kind of lead-free ceramic glaze and preparation method thereof.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of lead-free ceramic glaze, it comprises following component and weight content thereof:
Si0
262～64 parts, A1
20
37 parts, 5 parts of Ca0,3～4 parts of Mg0,4 parts of Ba0,3.5～4 parts of Sr0,7～8 parts of Zn0, K
25.5～6 parts of O, Na
20 4.5～4.8 parts, Li
23.5～4.5 parts of O, Fe
20
30.5～1.5 parts, B
20
36～7 parts, Zr0
22.5～3.5 parts, La
20
31～2.5 part.
Simultaneously, the invention provides a kind of preparation method of lead-free ceramic glaze, it comprises the steps:
S1: get 30～40 parts of the silica powders that 200 orders or thinner mesh screen sieve, the feldspar in powder that 200 orders or thinner mesh screen sieve: 25～35 parts, 12～15 parts of boraxs, 5～6 parts in zinc oxide, 2～4 parts of zirconium silicates, 1～2 part of lanthanum trioxide, 8～14 parts in calcium carbonate, 3～5 parts in magnesiumcarbonate, 1 part of rhombohedral iron ore, 2～4 parts of barium carbonates, 2.5～4 parts of Strontium carbonate powders, 5～8 parts of Quilonum Retards;
S2: after the step l spouse of institute raw material mixed, 1380 ℃～1450 ℃ fusings, put into the cold water shrend and make frit;
S3: frit is packed in the ball mill, and the kaolin or other glaze slip properties modifier that add water and 0～18 part grind to form glaze slip, and fineness is controlled at 10000-hole sieve and Yus 0.01～0.05 part.
Described step S3 is for packing frit in the ball mill into, and the sodium cellulose glycolate that adds water and glaze slip properties modifier l～3 parts grinds to form glaze slip, and fineness is controlled at 10000-hole sieve and Yus 0. 01～0.05 part.
Glaze of the present invention is not leaded, asepsis environment-protecting.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 scratches, to the disadvantageous shortcoming of colour generation; By optimizing SiO
2Content, improved hardness of glaze surface, taken into account the applicable performance to various colorant colour generations; By introducing rare earth compound lanthanum oxide, widen the firing range of glaze, and improved glossiness and the hardness of glaze, overcome because of the glaze firing narrow range, and the underburnt that causes and burning defective.Improved the qualification rate of product.
Embodiment
The present invention is further illustrated below in conjunction with specific embodiment.
Embodiment 1
With 32 parts of silica powders (200 order), feldspar in powder (200 order): 33 parts, 13 parts of boraxs, 5 parts in zinc oxide, 2 parts of zirconium silicates, 1 part of lanthanum trioxide, 8 parts in calcium carbonate, 3 parts in magnesiumcarbonate, 1 part of rhombohedral iron ore, 2 parts of barium carbonates, 3 parts of Strontium carbonate powders, 3 parts of Quilonum Retards.After above-mentioned raw materials mixed, 1380 ℃～1450 ℃ fusings, put into the cold water shrend and make frit.
Frit is packed in the ball mill, and the kaolin that adds water and 3 parts grinds to form glaze slip, and fineness is controlled at 10000-hole sieve and Yus 0. 01～0.05 part.Glaze is imposed on the china biscuit, in the kiln of packing into after the drying, burn till at 1020 ℃-1180 ℃ and to get final product.
