Background technology
Ceramic ink jet printing technology is a kind of technology being widely used in ceramic tile production in recent years, ink printed is replaced the decorative means such as conventional screen stamp, roller printing on adobe surface by shower nozzle by it, because it is that a kind of noncontact prints, male and fomale(M&F) product " can be printed ", do not need plate-making in kind, turn version simply rapid, personalized production can be realized, produce reproducible, thus use range is more and more wider.But its shortcoming is just that the ornament layer printed is excessively shallow, and meanwhile, it is poor that rear wear resistance fired by ink; along with the prolongation of duration of service; decorative effect can be made to have a greatly reduced quality, thus have on the ornament layer after spray ink Printing and execute transparent or cloth clear frit, to protect the technique of ornament layer decorative pattern.No matter but be transparent or clear frit, better decorative effect is presented in order to make ink-jet ornament layer, just must enhance the transparency, but it is (in order to increase transparency, many containing solubility promoters such as plumbous and zinc in glaze that while transparency improves, wear resistance also can decline, it is while increase glaze paint transparency, also glaze paint deliquescing is made, not wear-resisting), thus still fundamentally can not solve the problem keeping long-term decorative effect.
Application number CN 201210331440.6 discloses one and oozes colored porcelain brick and production method thereof, ooze colored ink and to be printed on by the mode of spray ink Printing by water miscible and to drench on the starch adhesive on adobe surface, although after infiltration, the decorative pattern of certain depth can be produced, but because starch adhesive water ratio is higher, cause the infiltration difficulty of the infiltration color glaze ink of water-based to increase, and also easily cause faulty nozzle because raw brick moisture content evaporate into shower nozzle.In addition, adopt the bell jar glaze slip drenched in adobe surface also easily to form the defect of edge projection, be unfavorable for the Difference Control after polishing.In addition, worldwide aqueous infiltrating glaze ink up to this point and immature, also can be applied to far away on actual ink jet unit and produce.
Thus when firing due to inconsistent with end base shrinking percentage and then can distortion be produced, raw green strength reduces, and easily splits brick.
Application number CN 201110187245.6 discloses and is a kind ofly applicable to the aqueous infiltrating glaze of spray ink Printing and the method for ceramic tile production thereof, is directly be printed in adobe by aqueous infiltrating glaze by spray ink Printing, then water spray helps and oozes.Up to the present and immature but in fact aqueous infiltrating glaze ink, also can be applied to far away on actual ink jet unit and produce.
In prior art, directly can enter klining after ink-jet printed, this is for aqueous infiltrating agent.But what adopt in this scheme is organic penetration glaze ink, and burn till if directly enter kiln high temperature, the organic constituent in ink can volatilize, and can affect color development like this, and if organic constituent remain in base substrate more, easily there is the defects such as pore when burning till.For overcoming the above problems, with in this programme, after charity organic infiltration color glaze ink and organic penetration-assisting agent ink, carry out drying, it can make organic materials slowly volatilize, and forms steady seepage gradient and contains the less precoat having machine aided to ooze material.So process can also save ink consumption simultaneously.
Preferably, in the above-mentioned methods, between step C and step D, also wrap a placement moulded pottery not yet put in a kiln to bake help the step of oozing and forming pervious course, help the time of oozing to be no less than 10 minutes.Ink carries out subsequent drying step as well after needing to form certain depth of penetration in base substrate again, because the organic constituent in drying process ink inside can volatilize, this can promote that the chromophoe constituent in ink spreads, if but the pervious course not forming certain depth just carries out drying, be easy to occur because of the too fast problem causing depth of penetration more shallow of volatilizing.For this reason, preferably before carrying out drying, first place to help for more than 10 minutes to base substrate and ooze, after forming the pervious course of certain depth, carry out drying again.
Preferably, described adobe is in step that after fabric and bed material adopt forehand secondary material distributing, compacting forms adobe and drying, and precoat thickness is 0.5-2.0mm.
The mode using bed material and fabric to carry out cloth has forehand cloth and instead breaks cloth two kinds, the mode of both differentiations is that precoat is in top or bottom, anti-beat cloth can better in the holding surface bed of material because of the texture of distributing technique formation, forehand cloth then easily control adobe thickness and planeness.For this, the moulded pottery not yet put in a kiln to bake provided in the present invention also tool uses penetration glaze ink to decorate, darker infiltration ornament layer is formed together with penetration-assisting agent ink, to this, the mode of preferred employing forehand cloth, because it can control thickness and its planeness of precoat in adobe preferably, and, precoat upper, in follow-up process of osmosis without the need to base substrate is overturn.
Preferred further, the thickness of described precoat is 0.8-1.2mm.
Preferably, described organic infiltration color glaze ink is the mixture of organic acid salt and ester in stepb, wherein organic acid salt be carboxyl acid group, at least one in sulfonate radical, sulfinate, thionothiolic acid root and the salt formed with at least one in the inorganic color development ion such as iron, cobalt, chromium, copper; Described ester is at least one in long chain alkane, isocaprylic acid methyl esters, pungent methyl caprate.The color development of organic infiltration color glaze ink mainly relies on inorganic color development ion wherein, different ions and different kinds of ions various combination can produce different colours, such as independent cobalt can produce bright-coloured blueness, the combination of iron, cobalt and chromium can produce black, can form abundant full-color effect by combining above.
Preferred further, described organic acid salt is the salt that at least one in the inorganic color development ion such as carboxyl acid group and iron, cobalt, chromium, copper is formed.Carboxylic acid, compared to other organic acid, have better osmotic effect, and it easily volatilizees in base substrate, residual few in base substrate, avoids the increased number of stomata produced in follow-up burning till because its volatilization produces, improves product quality.
Preferably, described spray ink Printing penetration glaze ink is print polychrome penetration glaze ink by different spray nozzles successively in stepb; By the mixing of different colours ink, can obtain abundant decorative effect, such as conventional is blue, red, yellow, black 4 looks, certainly, in actual applications not by above restriction, can arrange in pairs or groups to ink color according to demand.Also certain infiltration color glaze can repeatedly be printed repeatedly, to obtain saturated form and aspect.
Certainly, the spray ink Printing in step B can also use the mode of screen printing or rotary printing to substitute, but as ink, the mode charity of its more suitable use spray ink Printing, and ink-jet has better control to charity amount.
Preferably, the described penetration-assisting agent ink in step C is the mixture of organic acid and ester deter-mation, and organic acid is at least one in carboxylic acid, sulfonic acid,-sulfinic acid, thionothiolic acid; Ester is at least one in long chain alkane, isocaprylic acid methyl esters, pungent methyl caprate, is organic liquid material.Organic type penetration-assisting agent ink can be good permeate color glaze ink with organic type and be combined, have and promote its effect of permeating in base substrate, better can be saved the consumption of penetration-assisting agent ink by spray ink Printing mode, and the thickness of pervious course can be controlled.And according to the needs of depth of penetration, different depths infiltration (depth of penetration is adjustable within the scope of 0.2-1.5mm) can be realized by changing penetration-assisting agent ink printed number of times, the more simple methods such as spraying, roll printing, silk screen printing can certainly be increased below to reach same effect.Preferably adopt repeatedly inkjet printing methods.
Preferably, in this programme, the time of oozing is helped to be advisable for 15-30 minute, the depth of penetration that too short very difficult formation is enough, long, then can affect production efficiency.
Preferably, when the raw material that steps A uses is divided into fabric and bed material, in fabric containing mass percent be 0.1-2% titanium dioxide, 0.1-0.5% zinc oxide, 0.1-5% zirconium silicate or 0.5-5% help at least one in red dose.Can color development be promoted by adding above component, reaching the object of saving ink.Help red dose for a kind of assistant toner, its main component is nano silicon, and can obtain by buying, such as Mei Gao company has related products to sell.
When adopting bed material and fabric to carry out cloth, adobe its from bottom to top comprise: initial bed, precoat, it is the pervious course that 0.3 ~ 1.5mm organic liquid material is formed that described precoat comprises thickness.By the adobe of above structure, because pervious course has certain thickness after sintering, rubbing down process can be carried out, and the decorative pattern that pervious course is formed is also wear-resisting especially.
Further, in above ceramic tile moulded pottery not yet put in a kiln to bake, described precoat is embedded with striped or granular texture.Described striated texture forms (such as magic cloth) by the known Strand Feeding Technique of industry, can be the various textures such as wire, particulate state, cloud shape, wood grain, bag.Because what form above texture has different with all the other positions of precoat, make permeation layer thickness also have corresponding difference (different material depth of penetration is different), reduce the loss caused because of polishing further, meanwhile, also can enrich decorative effect.
Further, the thickness >=permeation layer thickness of described striped or granular texture.Even if like this because pervious course is crossed throwing in rubbing down process, be also unlikely to the Integral decoration effect affecting brick.
Compared with prior art, the present invention is by the fabric of penetration glaze ink charity after secondary material distributing, and use organic penetration-assisting agent of identical type, because both character are identical, use-pattern is identical, thus can ensure better depth of penetration, make the Wear Resistance after firing good, decorative pattern keeps lasting, and has certain thickness due to ornament layer, can carry out the processing such as chamfering.
Simultaneously, due to can the change of cloth system and the design of spray ink Printing pattern be passed through, the grain effect of precoat is combined with the decorative effect of penetration glaze, thus on starch adhesive, prints penetration glaze than prior art CN 201210331440.6 and there is easier operation and effectively solve the defects such as the infiltration of starch adhesive moisture disaster and edge projection; Owing to adding titanium dioxide, zinc oxide in fabric, help red dose, the assistant toner such as zirconium silicate, can obtain comprehensive color development and texture after high-temperature firing, the strong and stereoscopic depth sense of level transition sense by force, can produce abundanter color and darker osmotic effect; The tandem product of various luster degree also can be obtained after adopting the module polishing of known different meshes and hardness; Adopt the mould pressing unfired brick of different surfaces Z-Correct bump mapping Z-correct to obtain and there is the tandem product that stereoscopic sensation is stronger, texture is finer and smoother.
