A kind of ceramic glaze and manufacture craft thereof
Technical field
The invention belongs to the ceramic glaze technical field, especially relate to a kind of ceramic color glaze and prepare the technique of this color glaze.
Background technology
The producing and manufacturing technique of domestic ceramics industry traditional ceramics coloured glaze is: join according to a certain percentage ceramic coloring pigment or metal oxide in the parent glaze, and ball milling mixes and makes coloured glaze together, then take to soak the method for glaze or glaze spraying, coloured glaze is fixed on the ceramic body, form the coloured glaze glaze layer of 0.1~0.3mm, at last with on have product firing temperature and the calcining system as required of coloured glaze to fire, thereby obtain a kind of ceramic with the color color.But, according to this ceramic color glaze producing and manufacturing technique, there are many weak points in the product of producing: the bright-coloured degree of the colour generation of color is larger to the dependency of parent glaze, the chemical ingredients of parent glaze has considerable influence to the colour generation of colorant, so require different tinting pigments will have different parent glazes to be complementary with it, the color development effect of the best that just can reach, it is larger to guarantee that like this each color all reaches best color development effect technical difficulty, and technique is more numerous and diverse; Easily produce aberration in the ceramic product edges and corners, especially special-shaped and large part product aberration is obvious especially, because ceramic glaze is in a kind of glass rheology when high temperature, it can move down along product surface under action of gravity, and tinting pigment is blended in the glaze, it is mobile together that it can follow the glaze layer, cause at last the local color of glaze bed thickness dark, thin local of light color of glaze layer causes the product integral color inhomogeneous and form aberration, the number of times that such product flashes back is more, and aberration is obvious; To the high coloured glaze product of the heavy metals such as leaded, cadmium easily segregation out human body is damaged.When there is larger aberration in ceramic color glaze product, there are at present a lot of technician to remedy with regard to taking to beat colo(u)r streak in the product edges and corners or beating golden-rimmed mode, but do not have to solve the problem that there is aberration in ceramic color glaze goods, so not only cost is high, and not attractive in appearance at all.
Summary of the invention
One of purpose of the present invention is to provide a kind of ceramic glaze, solves the defective that prior art exists.
For achieving the above object, the present invention adopts following technical scheme:
A kind of ceramic glaze comprises basic glaze and tinting pigment, and described basic glaze comprises following component and weight percentage (wt%): SiO

Preferred scheme is: described tinting pigment is inorganic non-metallic pigment; Perhaps be the coloring metal oxide compound, described coloring oxide is one or several mixtures in ferric oxide, chromic oxide, cupric oxide, weisspiessglanz, nickel oxide, cobalt oxide, stannic oxide, the manganese oxide.
More preferred scheme is: also comprise the colorant suspension agent, described colorant suspension agent is that ammonia chloride is or/and magnesium chloride; Described colorant suspension agent is 0.5~3wt% of tinting pigment weight.
Two of purpose of the present invention is to provide a kind of technique for preparing ceramic glaze, adopts following technical scheme:
A kind of technique for preparing ceramic glaze comprises the steps:
(A) preparation of basic glaze:
(A1) get the silica powder 22~45% that 325 orders or thinner mesh screen sieve, get the feldspar in powder 23~43% that 325 orders or thinner mesh screen sieve, get the kaolin 0~15% that 325 orders or thinner mesh screen sieve, borax 2~20%, zinc oxide 2~7%, zirconium silicate 0~5%, calcium carbonate 6~16%, magnesiumcarbonate 0~8%, Vanadium Pentoxide in FLAKES 0~5%, Strontium carbonate powder 0.5~6%, Quilonum Retard 2~10%;
(A2) above-mentioned raw materials is mixed after, 1350 ℃~1500 ℃ fusings, put into the cold water shrend and make frit;
(B) preparation of tinting pigment:
Be 10 with tinting pigment and water according to weight ratio: (4~7) prepare, and colorant suspension agent mixing and stirring can use, and described colorant suspension agent is 0.5~3% of tinting pigment weight percent.
Preferred scheme is: described tinting pigment is one or several mixtures in ferric oxide, chromic oxide, cupric oxide, weisspiessglanz, nickel oxide, cobalt oxide, stannic oxide, the manganese oxide; Described colorant suspension agent is ammonia chloride and/or magnesium chloride.
Three of purpose of the present invention is to provide a kind of ceramic product, and described ceramic product comprises the coloured glaze that the described ceramic glaze baking of the arbitrary technical scheme of one of goal of the invention burning forms.
Four of purpose of the present invention is to provide a kind of technique for preparing the coloured glaze product, adopts following technical scheme:
A kind of technique for preparing the coloured glaze product comprises the steps:
(1) mode that the tinting pigment that the technique preparation of two described preparation ceramic glazes of goal of the invention is got is taked to spray or soak is fixed on the ceramic body, then oxydizing flame or reducing flame pate dure under 1150~1300 ℃ temperature;
(2) the look tire behind porcelain spray or soak basic glaze glaze firing system 5~8h that the technique preparation of two described preparation ceramic glazes of one deck goal of the invention gets and get finished product, the temperature of glaze firing of described basic glaze is lower than 80~150 ℃ of porcelain temperature.
The present invention compared with prior art has following advantage and beneficial effect:
The present invention is by separating the tinting pigment in the coloured glaze (tinting pigment preferable alloy oxide compound) and basic glaze, and burning till through twice differing temps, the mode of first tinting pigment or metal oxide being taked to spray or soak is fixed on the ceramic body, burn till porcelain through high temperature again, then the look tire behind porcelain spray or soak the coloured glaze parent glaze that one deck temperature of glaze firing is lower than 100~150 ℃ of porcelain temperature and burn till, solve the aberration of ceramic color glaze product, color development is not just and plumbous, the problem of the heavy metal contaminations such as cadmium, solve simultaneously tinting pigment or metal oxide to the Dependence Problem of parent glaze, reduce the production difficulty of ceramic color glaze product.Coloured glaze product according to production technique method production of the present invention, colour generation is even, bright in colour, beautiful, there is not the pollution problem of the heavy metal elements such as aberration and lead, cadmium, and through twice or repeatedly burn till defectives such as aberration, look flower also can not occur, the product colour color development is bright-coloured, evenly pure, elegant in appearance, beautiful in colour, and is green health pottery truly, enrich the kind of ceramic color glaze, improved quality and the class of ceramic color glaze product.The present invention introduces Vanadium Pentoxide in FLAKES (P simultaneously
2O
5) as minute phase composition of tinting material, be not subjected to the impact of cover-coat enamel when allowing the color color development, guarantee that the color development of tinting pigment is abundant.
