Summary of the invention
The object of the present invention is to provide one kind before green body printing ornament, first applies one layer of translucent glaze layer, semi-transparent
Inkjet printing decoration emulation spot is carried out in bright glaze layer, is reached and is weakened green body spot bring colour fluctuation itself and particle shunting
The unequal influence of bring spot, Lai Shixian brindled brick pimple stabilization, level visual effect, not only solves green body spot face
The uncontrolled problem of color, and brindled brick visual effect is not lost, key emulation ghost spot production process is evenly distributed, and not will cause spot
Point granular size shunts, conventional without carrying out complicated a transfer or secondary transfer process to green body spot itself again
Be granulated can steady production stabilization brindled brick preparation method.
The preparation method of the technical solution of the invention is as follows the stable brindled brick, is characterized in that, including with
Lower step:
(1) green body is suppressed: green body powder is made of conventional powder and spot;0.3~0.6 millimeter of conventional powder particle size, spot
1~3 millimeter of powder particle size, spot is made of three kinds of white, blue, black spots, and wherein white dot proportion 5~10%, blue
Color color spot point proportion 10~20%, black splotch proportion 70~80%;
(2) body drying: 80~130 DEG C of drying temperature, drying time 40~60 minutes;
(3) simulation process: before pattern decorative, translucent glaze layer together, glaze layer color tune are first applied in billet surface in advance
To close to billet surface color, then again by inkjet printing decoration technique, print close with green body spot size and color
Ink-jet ghost spot, realize the emulation of visual height, the color and spot effect and green body color of translucent glaze and surface are imitated
Fruit is almost the same;
(4) pattern decorative: after simulation process, screen printing decoration, rubber roller printing ornament, inkjet printing stamp dress are carried out
Decorations carry out pattern effect and color effects decoration, adjust ceramic tile surface color decorative effect;
(5) protection glaze is applied: through screen printing or rubber roller stamp or ink-jet printed decoration technology decorative colors, pattern
After effect, finally apply layer of transparent glaze slip again and carry out protection decoration, increases emulation spot heavy feeling in translucent glaze layer, realize
Spot is sunken under glaze layer, realizes that height emulation is merged with green body spot itself;
(6) be burnt into: firing temperature is at 1150~1250 DEG C, firing time 40~60 minutes.
As preferred: the translucent glaze stratification study be grouped as it is as follows:
SiO245~60% |
Al2O313~25% |
CaO 4~7% |
Na2O 3~10% |
ZnO 2~4% |
BaO 3~10% |
|
|
Glazing specific gravity is between 1.15~1.35, and glaze volume is in 50~100 grams/block.
As preferred: the protection glaze slip chemical composition is as follows:
SiO245~55% |
Al2O315~23% |
CaO 7~15% |
Ka2O 5~10% |
ZnO 1~4% |
BaO 5~10% |
|
|
Between specific gravity 1.15~1.35, glaze volume is in 50~100 grams/block;Glazing mode: glaze cabinet glaze spraying.
Compared with prior art, beneficial effects of the present invention:
(1) the present invention first applies one layer of translucent glaze layer in ceramic tile surface, can appear green body spot effect and buffer spot
Point variation realizes spot brick product continuous and stable production to ceramic tile Color influences.
(2) the present invention carries out inkjet printing decoration emulation spot in translucent glaze layer, reaches and weakens green body spot band itself
The colour fluctuation come and particle shunt the unequal influence of bring spot, Lai Shixian brindled brick pimple stabilization, level vision
Effect can reach spot fidelity and stability by using ink-jet printed technology, eliminate the reliance on additional spot in green body,
Production cost is reduced, transfer process is reduced.
(3) emulation ghost spot production process of the invention is evenly distributed, and not will cause granular size shunting, and use is more smart
The reasonable production technology of letter not carry out complicated a transfer or secondary transfer process, often to green body spot itself again
Rule are granulated can steady production.
(4) this invention simplifies production technologies, reduce investment, reduction in terms of production blank cost and relevant device, personnel
Waste water and gas discharge.
(5) the present invention improves brindled brick process stability, reduces to green body intrinsic colour and spot degree of dependence,
Reduce the transfer process of green body complexity.
(6) it is different by adjusting translucent glaze layer from ink jet printing performance can flexibly and effectively to adjust product by the present invention
Stippled finish effect, it is no longer necessary to complicated granulation process shortens production time and process flow.
(7) the present invention eliminates the reliance on green body color or green body spot to realize spot effect, the technological process of production and common production
The product technological process of production is general, adaptable, versatile, can effectively reduce process waste.
Specific embodiment
The present invention will now be further detailed embodiment:
The preparation method of the stable brindled brick, comprising the following steps:
(1) green body is suppressed: green body powder is made of conventional powder and spot;0.3~0.6 millimeter of conventional powder particle size, spot

Spot proportion 16%, black splotch proportion 76%;
(2) body drying: 80~130 DEG C of drying temperature, drying time 40~60 minutes;
(3) simulation process: before pattern decorative, translucent glaze layer together, glaze layer color tune are first applied in billet surface in advance
To close to billet surface color, then again by inkjet printing decoration technique, print close with green body spot size and color
Ink-jet ghost spot, realize the emulation of visual height, the color and spot effect and green body color of translucent glaze and surface are imitated
