Summary of the invention
The purpose of this invention is to provide a kind of in-glaze decoration decorative daily-use porcelain and production method thereof, comprise blank formulation and enamel prescription, overcome that present in-glaze decoration decorative daily-use porcelain products color and luster is bright-coloured inadequately, assortment are few, cost is higher, are difficult to form the shortcoming of suitability for industrialized production.
The present invention is achieved through the following technical solutions:
A kind of in-glaze decoration decorative daily-use porcelain, its base substrate comprises following component by weight percentage: Longyan clay raw ore 15-21%, weathered potash feldspar 9-13%, Jiepai clay 9-15%, potassium felspar sand 8-12%, Calcined polishing aluminum oxide 7-11%, Guizhou clay 4-6%, Longyan clay are washed mud 20-26%, quartzy 8-16%.
Described base substrate is preferably following component by weight percentage: Longyan clay raw ore 18%, weathered potash feldspar 11%, Jiepai clay 12%, potassium felspar sand 10%, Calcined polishing aluminum oxide 9%, Guizhou clay 5%, Longyan clay mud 23%, quartzy 12%.
The production method of this in-glaze decoration decorative daily-use porcelain may further comprise the steps: make marble paper in base substrate, enamel and the glaze earlier, then with the base substrate glazing, marble paper in the glaze is pasted in biscuiting, and roasting again burning till is finished product.
Described base substrate is made by following technology: first preparation pug, through add water for ball milling, the deironing of sieving, press filtration, thick experienced, old, concise, moulding, drying.
Described enamel comprises following component by weight percentage: useless porcelain powder 20-25%, feldspar 8-13%, lithium porcelain stone powder 2-6%, quartzy 23-28%, kaolin 8-12%, zinc oxide 3-8%, rhombspar 8-13%, calcite 10-15%.
Described enamel is made by following technology: with glaze with feed proportioning after, add water for ball milling, sieve, deironing, to go into the glaze stock tank old, standby.
Marble paper is made by following technology in the described glaze: decorative pattern and color according to product design require to select pigment in the ceramic glaze, press pigment: the weight ratio of stand linseed oil=10: 7 adds after stand linseed oil grinds, with method for printing screen with color-printed to the membranelle base stock, it is standby to make in the glaze marble paper.
Described biscuiting temperature is 1240-1260 ℃, and firing time is 5-7 hour.
Described roasting burning temperature is 1100-1150 ℃, and the roasting burning time is 3-5 hour.
The invention has the beneficial effects as follows:
The present invention becomes porcelain for making the porcelain base between 1240-1260 ℃, some mineralizers in blank, have been added, whiteness after base substrate is burnt till reaches about 85, folding strength reaches 185MPa, water-intake rate is less than or equal to 0.02%, thermostability reaches 200 ℃ to 20 ℃ heat exchanges and does not burst, and meets the technical requirements of strengthening porcelain.
Glaze of the present invention is considered the swelling property of porcelain base the coefficient of expansion of glaze and base substrate to be complementary on prescription.Can under middle tender feeling condition, finish physical and chemical reaction rapidly on the one hand,, be wrapped in porcelain base surface, make the ceramic whiteware that burns till reach processing requirement with the base substrate good combination; Be on the other hand when ceramic whiteware is decorated the roasting burning of applique, allow marble paper pigment all sink in the glaze layer, thereby play transparency protected effect, form the decorative effect of in-glaze decoration color.
In-glaze decoration trailing of the present invention, it is rich and varied to make the porcelain product reach color, and bright in luster bright, will never fade, the glaze feel is level and smooth, and plumbous quantity of cadmium release is few, safety and sanitation.Product strength height, hardness of glaze surface are big, are difficult for damaging, and smooth finish, transparence and thermostability are all fine, are suitable for producing in enormous quantities.
Embodiment
Be that the in-glaze decoration Decorative porcelain plate of red rose is that example is described in detail the present invention with a kind of face pattern of spending below.
This in-glaze decoration Decorative porcelain plate, its base substrate comprises following component by weight percentage: Longyan clay raw ore 18%, weathered potash feldspar 11%, Jiepai clay 12%, potassium felspar sand 10%, Calcined polishing aluminum oxide 9%, Guizhou clay 5%, Longyan clay are washed mud 23%, quartzy 12%.
The production method of this in-glaze decoration Decorative porcelain plate may further comprise the steps:
(1) base body: first preparation pug, through add water for ball milling, the deironing of sieving, press filtration, thick experienced, old, concise, moulding, drying, make the porcelain dish base substrate.
(2) porcelain making glaze: enamel comprises following component by weight percentage: useless porcelain powder 22%, feldspar 1 1%, lithium porcelain stone powder 4%, quartz 25%, kaolin 10%, zinc oxide 5%, rhombspar 11%, calcite 12%.Add water for ball milling with after the above-mentioned raw materials batching, sieve, deironing, the old enamel of making.
(3) marble paper in the enamel frit makeing: according to the product design requirement, select the roasting pigment in the ceramic glaze that the back colour generation is a redness that burns, press pigment: the weight ratio of stand linseed oil=10: 7 adds after stand linseed oil grinds 4 times, with method for printing screen with color-printed to the membranelle base stock, make marble paper in the glaze that is printed on the rose pattern.
(4) after marble paper completes respectively in above-mentioned porcelain dish base substrate, enamel and the glaze, with the base substrate glazing, biscuiting is 6 hours in 1250 ℃ kiln, pastes marble paper in the glaze then, the roasting burning 4 hours in 1125 ℃ kiln, the in-glaze decoration Decorative porcelain plate that promptly to become colored face pattern be red rose.
