Abstract

The invention relates to a method for manufacturing a paint Tang sancai ceramic handiwork, which is characterized in that dolomite or red earth soil is subjected to mechanical press according to a preset mould; the pressed blank is subjected to one-time calcinations at a temperature between 800 and 1,100 DEG C to form a white blank; and the white blank is immersed in a water-based paint for 2 to 3 seconds, dried, and subjected to corresponding painting according to the effect on the surface. The method has the characteristics of simple production procedure, low cost, good art visual effect, more energy conservation and more health and environment protection.

Description

A kind of preparation method of paint type Tang three-color ceramics handicraft article

One, technical field

The invention belongs to the ceramics manufacture technology field, refer more particularly to a kind of new method of paint type Tang three-color ceramics handicraft article.

Two, background technology

Existing tri-coloured glazed pottery system continues to use traditional preparation method, promptly is that primary raw material fashions into carcass with the clay, carries out biscuiting, glazing then, and gloss firing, the firing temperature of its biscuiting generally is no more than 1100 degrees centigrade, if surpass 1000 degrees centigrade, base substrate will softening transform; In this temperature, when surpassing 1000 degrees centigrade, base substrate can produce certain porcelainization, but does not reach the degree of complete porcelainization, and makes glazing work become very difficult.Therefore, the biscuiting temperature of base substrate can only be controlled between 850---950 degree centigrade, like this, base substrate just has water imbibition preferably, so that use the writing brush glazing smoothly.The temperature of twice firing is carried out in glazing later on, also can only be controlled at about 950 degrees centigrade.Fire in this way its intensity of tri-coloured glazed pottery of making a little less than, the tri-coloured glazed pottery ceramic of prior art production simultaneously all is to burn through twice base, because twice base burns and increased technology difficulty, cause yield rate have only 85% less than, increased the cost of product greatly, in addition because in the prior art, contain elements such as chemistry such as a large amount of magnesium, zinc, lead, cadmium in pattern color and the glaze formula, make the color formulas cost height of prior art, and the ceramics that generates contains lead and waits other human body and environment to be easy to generate the metallic element of pollution.

Three, content of the present invention

The object of the invention be to have solved weak point of the prior art and provide that production process is simple, cost is low, artistic visual is effective, more energy-conservation, the preparation method of the tri-coloured glazed pottery ceramics of a kind of lacquer property of health environment-friendly more.

The present invention realizes in the following way, adopt white clouds soil or red soil, forge and press through machine according to the model that pre-sets, to forge and press good green compact then and form openpore through once calcining the back at 800-1100 degree centigrade, then openpore is inserted aqueous paint and soak 2-3 second, colouring is painted accordingly according to the effect that the surface presents in dry back.

From the above mentioned, the present invention burns twice base and becomes the base burning one time, replace glaze and ceramics ice crack glaze made of glass slag with specialized paint simultaneously, adopt the preparation method of this production method tri-coloured glazed pottery ceramics have that production process is simple, cost is low, artistic visual is effective, more energy-conservation, health environment-friendly characteristics more.Adopt the inventive method to make the tri-coloured glazed pottery ceramic process, in bright gay color, technology is simple, yield rate can reach 99.9%, cost is low, unleaded and other poisonous metals, pollution-free to environment and human body, and energy consumption is low, for this energy-conservation, simple new its market prospects of preparation method of environmental protection, technology are boundless, are worth promoting.

Four, the specific embodiment of the invention

The concrete operations step of the inventive method is as follows:

The inventive method is to adopt white clouds soil or red soil,, will forge and press good green compact then and form openpore through once calcining the back through the machine forging and pressing according to the model that pre-sets, and this is first manufacture craft to operation----openpore of making.

And then openpore technology be exactly the colouring operation of this method after finishing, and step is mainly as follows:

First procedure is exactly to bleach in the middle of the openpore that calcining is good is put into the container that includes aqueous paint, soak after 2 to 3 seconds and take out, wait to be dried then, dry mode can be taked artificial drying or natural drying, the time of airing can and take the different of mode to decide according to the humidity of the height of temperature and air, take artificial drying, generally only need half an hour; If take natural drying, generally be to dry half a day.

Second operation work is painted exactly, concrete operating procedure is that the base substrate that will dry is unified color spray with machine or with artificial hand-held painting pen brushing, demand and the different of hobby according to the client can adopt following several mode to select the oiliness paint vehicle that will paint for use, and concrete embodiment has following several:

Embodiment 1: the PU series oil paint of paint metals material

On the openpore that dries, next painted with the PU series oil paint of paint metals material, the tri-coloured glazed pottery ceramics of making by the PU series oil paint of paint metals material can reach surperficial anti-zoned, limpid in sight bright artistic effect.

Embodiment 2: the brushing polyester paint

On the openpore that dries, next painted with the polyester paint of brushing furniture material, the paint type Tang three-color ceramics handicraft article of making by the brushing polyester paint can reach surperficial mellow and full, the artistic effect that color is full.

Embodiment 3: the brushing crackle paint

On the openpore that dries, come painted with the brushing crackle paint, and can on the model of oneself spray crackle priming paint, spray sample in advance according to requirement of client, effect according to the crackle size, choose the working viscosity of crackle finish paint, the thickness of paint film, regulate spray gun shape, air pressure, go out lacquer amount (typing).Crackle finish paint viscosity is big, paint film thickness, and crackle is just slow, and the crackle lines is big; Otherwise crackle is fast, little.The spraying of crackle finish paint must be even, otherwise just crack the irregular effect of size.Ambient humidity is excessive, temperature is too high, cross and should not construct when low, in order to avoid produce ill effect.

The more remarkable effect that the paint type Tang three-color ceramics handicraft article of making by the brushing crackle paint is reached with the brushing nitrate paint, can control simultaneously the amplitude and the size of ice crack as required, also need not take the firing equipment transient heating, directly the brushing crackle paint just can reach very natural ice crack effect on the base substrate that dries, and more glittering and translucent, more can play in bright gay color, jewelly artistic effect.
