Abstract
The invention discloses a kind of ceramic opaque glaze and preparation method thereof, the ceramic opaque glaze includes following raw material：Potassium feldspar, quartz, apatite, kaolin, calcite, fluorite, zeolite, zinc oxide, barium carbonate.The ceramic opaque glaze of the present invention burn till rear whiteness is high, opaque effect is excellent, in raw material zirconium silicate dosage it is low or be entirely free of zirconium silicate, production cost it is low, especially suitable for sanitary ceramics.
Description
Technical field
The present invention relates to the technical field of ceramic opaque glaze.
Background technology
Opaque glaze is White-opalescent bright glaze, and the generation of milkiness phenomenon is typically realized by two kinds of situations, first, glaze
It is middle the huge two-phase interface of refractive index difference to be present, it is because scattered crystallite in glaze be present in addition.
Sanitary ceramics refers to the band glaze ceramic for being applied to the place such as toilet, kitchen or laboratory, and in the market is current
Generally using the sanitary ceramic ware in white color You face, in use due to sanitary ceramics surface it is continuous wash away and
Corrosion（Such as the use of ceramic pedestal pan）, the surface roughness of Wei Sheng porcelain You can be continuously increased, and continue to increase its cleaning difficulty,
The ceramic enamel surface of milkiness particularly in a manner of fine-grain, the change of its roughness are even more serious.
The opaque glaze that domestic sanitary ceramics uses is the decoration glaze that opacifiers is made with zirconium oxide mostly, and these decoration glaze
It is to realize the introducing of zirconium oxide by adding zirconium silicate mostly.On the one hand, with the rise of zirconium silicate price, particularly health
Introduced zirconium silicate accounts for more than 15% mostly in ceramic glaze, and the formulation cost for causing sanitary ceramics opaque glaze is very high；Separately
On the one hand, a large amount of uses of zirconium silicate, the quality of zirconium silicate raw material, such as wherein content of zirconium oxide, powder fineness are also caused
Influence Deng the smoothness to Ceramic glaze and glaze paint whiteness is very big, in the prior art mainly by zirconium silicate raw material
Superfine grinding, the quality of sanitary ceramics opaque glaze improved using measures such as the high-quality zirconium silicates of import, and on ceramic glaze group
It is relatively fewer into the improvement in terms of composition.
The content of the invention
It is an object of the invention to propose that a kind of whiteness is high, zirconium silicate dosage is low, opaque effect is excellent, chemically-resistant and physics
Corrosivity is good, wash away repeatedly rear surface roughness change it is less, especially suitable for the ceramic opaque glaze of sanitary ceramics, the present invention
Purpose also reside in propose the ceramic opaque glaze preparation method.
Technical scheme is as follows：
A kind of ceramic opaque glaze, it includes following raw material：Potassium feldspar, quartz, apatite, kaolin, calcite, zeolite, oxidation
Zinc, fluorite, barium carbonate.
Its preferred embodiment is：The ceramic opaque glaze includes following raw material：15 ~ 35wt% of potassium feldspar, quartz 5 ~
15wt%, 10 ~ 15wt% of apatite, 5 ~ 10wt% of kaolin, 10 ~ 20wt% of calcite, 5 ~ 15wt% of zeolite, 1 ~ 5wt% of zinc oxide, firefly
5 ~ 10wt% of stone, 1 ~ 5wt% of barium carbonate.
Its further preferred embodiment is：The ceramic opaque glaze includes following raw material：15 ~ 35wt% of potassium feldspar,

Its another further preferred embodiment is：Potassium feldspar in the raw material, quartz, apatite, kaolin,
Calcite, zeolite, zinc oxide, fluorite, the particle diameter of barium carbonate are respectively less than 50 μm, and the particle diameter of zirconium silicate is less than 20 μm.
Present invention further proposes the preparation method of the ceramic opaque glaze, it is characterised in that：Comprise the following steps：
（1）Weigh the raw material；
（2）The raw material is added in ball mill, and adds 50% water that quality is the raw material gross mass and carries out ball milling, extremely
Glaze slip fineness is that 300 ~ 325 mesh sieve margins are less than 0.1%.
（3）Iron removaling is carried out to gained glaze slip, that is, obtains the ceramic opaque glaze.
The ceramic opaque glaze of the present invention includes apatite, fluorite and zeolite, and F and P are introduced simultaneously in ceramic glaze
Deng chemical element, wherein the zirconium silicate for being introduced into a small amount of content that can promote in ceramic glaze of P element is with superfine crystal
Size separation goes out, so as to the opaque effect in Zeng Qiang You face；And being introduced into while F and P element can promote glaze compositions to be produced in glaze paint
Raw glass phase-separating, so as to form the opaque effect based on split-phase.These synergies between raw material, on the one hand can effectively drop
It is low on the other hand to improve the roughness in Wei life Tao Ci You face even without opacifiers of the zirconium silicate as glaze is added,
So that fire after ceramic opaque glaze face smooth even, and ensure its in Reusability, wash away, holding surface during friction
The stabilization of roughness, it is homogeneous, holding surface it is smooth.
The present invention possesses following beneficial effect：The present invention forms milkiness by the synergy between raw material with phase separation
Effect, in further preferably, a small amount of zirconium silicate is separated out with fine grain particle, can be significantly increased opaque effect, is achieved in
Zirconium silicate is used no or little, effectively reduces production cost；The ceramic opaque glaze chemically-resistant and physics being prepared by the present invention
Corrosivity is good, washes away rear surface roughness repeatedly and changes smaller, glaze paint smooth even all the time；The ceramic opaque glaze of the present invention is fired
Glaze paint smoothness is high afterwards, and snowy white is presented, and has unique decorative effect.
