The production process comprises the steps of forming cloth material, applying ground coat, printing, applying cover glaze, sintering, polishing and grinding, wherein ground coat used in the ground coat applying step is phosphor-boron or boron-calcium multiphase opaque glaze, and the ground coat contains 0.5%-3% (in percent by mass) of anatase titanium oxide and 0.5%-5% of attapulgite. Compared with the prior art, the glazed brick production process provided by the invention has the advantages that the glazed brick production process is less in ink dosage, clear in color, and almost free of chromatic aberration color cast; moreover, inkjet blocking probability is lowered, cleaning and maintaining times of a spray head are reduced, production continuity is improved, and a situation of midway downtime rarely happens except from necessary maintenance.
Description
Technical field
The present invention relates to architectural pottery production technology, relate in particular to a kind of throwing glazed brick production technique.
Background technology
Throwing glazed brick is popular in recent years a kind of ceramic wall and floor bricks product, and it,, by impose stamp after ground-coat enamel in adobe, imposes layer of transparent cover-coat enamel afterwards again, after entering klining and becoming, more transparent cover coat is carried out to polishing, obtains throwing glaze brick product.It has the effect of in-glaze decoration, and printed layer, under the protection of transparent cover coat, can not be worn substantially; And through polished finish, make product glossiness high, good decorating effect.
Inkjet technology is the third generation printing technique after rotary printing and screen printing, and it,, by ink-jet printer, prints pattern according to predetermined pattern in adobe.The ink that at present ceramic ink jet printer is used mostly is oil-based ink, needs still to keep after high temperature sintering the color and luster of pattern, and the color development component in ink is mainly high temperature inorganic color, and needs color development stable.For guaranteeing the clear of logo printing layer, the ground glaze layer that imposes on billet surface needs higher whiteness, the sharpness of the ink-jet printed rear pattern of guarantee like this, therefore ground-coat enamel adopts zirconium base glaze substantially, but zirconium substrate glaze is influential to most ink colour generations, this just needs to increase with China ink to measure and guarantee color development effect.And some colour system is responsive to ground-coat enamel Component comparison, for example blue and fuchsin colour system ink has certain colour cast in zirconium substrate glaze, causes for presenting the color and luster impacts such as purple, pink larger.This is because color development pigment fineness≤1 μ m in ink, in sintering process, is easily wrapped up by zirconium base, affects color development effect, causes the defects such as colour cast, look shallow.And zirconium base glaze has certain radioactivity, although select at present more options zirconium silicate or boron zirconium frit to use, also higher compared with the glaze radioactivity of other component." Chinese industrial pottery " the 17th the 4th phase of volume of August in 2010 discloses document number and has been: the 1006-2874(2010) documents and materials of 04-0001-07 " research of environmentally friendly high opaque glaze ", it discloses: with Ca

Summary of the invention
The object of the invention is to propose a kind of throwing glazed brick production technique, it can avoid the impact of ground-coat enamel on ink-jet printed layer color development in sintering process, saves ink, reduces shower nozzle blocking probability, enhances productivity.
For reaching this object, the present invention by the following technical solutions: a kind of throwing glazed brick production technique, it comprises the steps:
Step 1) cloth moulding: select ceramic wall and floor bricks to produce conventional raw material, impact briquetting after ball milling, deironing, old, granulation, makes adobe;
Step 2) execute ground-coat enamel: by after the stamping forming brick bat drying of step 1, by the mode of glaze spraying or pouring glaze, execute ground-coat enamel;
Step 3) stamp: after ground-coat enamel is dry, select the ink-jet printed layer of ceramic ink jet printing machine ink-jet printed formation on ground-coat enamel;
Step 4) is executed cover-coat enamel: after stamp, by glaze spraying or pouring glaze mode, execute cover-coat enamel, described cover-coat enamel is transparent;
Step 5) is burnt till: enter roller kiln oxidizing atmosphere and burn till, 1100～1220 ℃ of firing temperatures, firing period 70～120 minutes;
Step 6) rubbing down: after burning till, treat that goods are cooling, carry out edging and polishing, obtain finished product;
It is characterized in that: step 2) described in ground-coat enamel be phosphorus boron or the heterogeneous opaque glaze of boron calcium, and in described ground-coat enamel, to contain mass fraction be 0.5%～3% anatase type titanium oxide or 0.5%～5% attapulgite.
Select in phosphorus boron or the heterogeneous opaque glaze of boron calcium and do not contain zirconium, radioactivity is lower; And add therein anatase type titanium oxide can enter in glaze in phase-splitting small droplets, and then the wrapped probability of color development colorant in minimizing ink, and anatase type titanium oxide itself just has opaque effect, can further increase ground-coat enamel whiteness, allow ink obtain better color developing effect.Attapulgite claims again polygorskite (Palygouskite) or Palygorskite, be a kind of tool chain laminate structure containing Shuifu County's magnesium silicate clay mineral.Attapulgite has unique dispersion, high temperature resistant, the anti-good colloidal property such as saline and alkaline and higher adsorption bleaching ability.And there is certain plasticity-and cohesive force, there is the intermediate structure between chain-like structure and laminate structure.Its structure belongs to 2:1 type clay mineral.In each 2:1 unit structure layer, tetrahedron wafer angle is pushed up direction at a certain distance and is put upside down, form layers chain.At tetrahedron bar interband, form the passage parallel with chain, filling zeolite water and crystal water in passage.Therefore add the viscosity that can increase glaze slip in ground-coat enamel, have preferably and adhere to; And when burning till, in above-mentioned passage, filling zeolite water and crystal water can decompose, in ground-coat enamel, in the above-mentioned passage of milkiness phase-splitting small droplets meeting partial insertion, reduce the impact on ink color development, make ink obtain preferably color development effect.
Preferably, in above-mentioned throwing glazed brick production technique, in described ground-coat enamel, the shared mass fraction of anatase type titanium oxide is 1%～1.5%.When add-on is less, DeGrain, adds when more and may make opaque effect variation, and the defects such as glaze is crude, pin hole increase.
Preferably, in above-mentioned throwing glazed brick production technique, in described ground-coat enamel, the shared mass fraction of attapulgite is 2%～4%.Similar with anatase type titanium oxide, add when few, DeGrain, when more, also can reduce glaze quality.
The present invention also discloses a kind of preferred version, and in above-mentioned throwing glazed brick production technique, in described ground-coat enamel, adding mass fraction is 0.5%～2% stannic oxide.Stannic oxide, as a kind of good opacifying agent, can obtain the better glaze of opaque effect, and can improve glaze quality, makes smooth, the basic no pin-hole defect of glaze.
The present invention also discloses a kind of preferred version, and, in above-mentioned throwing glazed brick production technique, when described ground-coat enamel is the heterogeneous opaque glaze of boron calcium, wherein said calcium constituent is introduced by wollastonite.
In above-mentioned throwing glazed brick production technique, the iron in described ground-coat enamel or manganese element content sum≤0.1%.
In above-mentioned throwing glazed brick production technique, described in to execute the ground glaze layer thickness that ground-coat enamel step forms be 0.2mm～0.5mm.
Compared to the prior art; throwing glazed brick production technique provided by the invention has following advantage: ink consumption is few; color development is clear; basic no color differnece colour cast; and the reduction of ink-jet blocking probability, shower nozzle cleaning maintenance number of times reduces, and improves the continuity of producing; except necessary maintenance, seldom there is shutdown situation midway to occur.
