Description
Technical field
The present invention relates to ceramic tile production technical field, especially relate to one and once burn microcrystallite glass-ceramic composite brick and production method thereof.
Background technology
Most of transparent glass and over-glaze decoration Ceramic Composite panel products adopt twice firing production technique mostly in the market: namely first carry out first time high temperature through roller kiln and burn till, the temperature generally adopted is generally 1160 ~ 1220 DEG C, first prepare the over-glaze decoration biscuit of ceramics through screen printing or rubber roll stamp, and then secondary burns low-temperature transparent frit dry granular on cloth, enter again in roller kiln and carry out second time and burn till, general firing temperature is 1050 ~ 1100 DEG C, main purpose is that over-glaze decoration ceramic body and clear frit are combined with each other, work in-process are again through polished finish, thus obtained transparent glass and over-glaze decoration Ceramic Composite board finished product.
Adopt the main purpose of high temperature biscuiting to be get rid of the most of organism in base substrate, thus reduce secondary glaze firing to the impact of glass-ceramic layer glaze paint, reduce production control difficulty, improve production stability.
Current architectural pottery market competition is growing more intense, but owing to adopting twice firing complex production process, its total cycle all more than more than four hours (namely the production cycle is long), therefore cause the production cost of product higher, floor space is large, one-time investment is large, particularly the inferior position of high energy consumption manifest more outstanding, accordingly, more and more producer develops a high temperature firing process further, the temperature generally adopted at present is generally 1160 ~ 1220 DEG C, time is under the condition of 60 ~ 180 minutes, glass-ceramic layer also has thinning trend simultaneously, with make product commercially cost have more competitive power,
But be no matter in traditional sense twice firing and high temperature once-firing technology, promote at market terminal in recent years, still exist and severally as follows compare distinct issues:
(1) no matter be twice firing or once-firing technology, the coefficient of expansion difference of glass-ceramic layer and ceramic substrate is comparatively large, and still there is delayed crazing after compound and easily cause cutting cracking, therefore thinning glass-ceramic layer is more effective direction;
(2) in current once-firing traditional technology, in order to ensure green strength, in body recipe, clay content generally all will more than 20%, and other overwhelming majority is natural porcelain sandy plain material in formula, the overall loss on ignition of base substrate is larger, generally more than more than 4%, and one subsynchronously to complete in high temperature due to base glaze, require very harsh to the state of the art of transparent microcrystal dry granular and Technical innova-tion, overall row yielding difficulty compared with twice firing increases greatly, and the acid and alkali-resistance index of current most the finished product is generally difficult to reach.
(3), in twice firing, a biscuiting brick controls to there is larger difficulty, is thus technically difficult to realize glass-ceramic layer thinning; And once-firing is once thinning, relevant contracting glaze needle pore defect increases, and antifouling capacity reduces greatly, and production control difficulty is too large.
Summary of the invention
The object of the invention is by introducing a kind of body recipe technology strengthening architectural pottery large gauge floor tile green strength and reduce overall loss on ignition, the white cosmetic soil formula of a kind of highlighted height is coordinated while guaranteeing the green strength needed for suitability for industrialized production, significantly reduce base substrate exhaust in sintering process to have a negative impact in glass-ceramic layer melting process, the once burning microcrystallite glass-ceramic composite brick of the technical bottleneck difficult problem that the contracting glaze, pin hole, evil mind, acid and alkali-resistance, soil pick-up etc. that effectively easily occur in the production of solution traditional once-firing microcrystallite glass-ceramic composite brick are the most outstanding.Another object of the present invention is to provide a kind of by reducing firing temperature more than 100 degree, effectively evade the foamed phenomenon that waste residues of polished tiles a large amount of in base substrate may cause, realize once burning microcrystallite glass-ceramic composite brick and the production method thereof of the cycling and reutilization of architectural pottery waste material.
Technical solution of the present invention is: describedly once burn microcrystallite glass-ceramic composite brick, and its special character is, this ceramic tile is made up of following component by weight:
As preferably: described ceramic tile formula is made up of following component further:
Adopt the blank formulation of low loss on ignition, overall loss on ignition controls as being less than 3%.

Another technical solution of the present invention is described production method of once burning microcrystallite glass-ceramic composite brick, it is characterized in that, comprises following production process:
(1) blank dry-pressing formed obtained ceramic green after wet ball grinding, spray drying process;
(2) execute ground-coat enamel after ceramic green drying, become over-glaze decoration base through printing decoration, then apply dry-type belt material distributing machine, charity transparent glass-ceramics frit dry granular on over-glaze decoration base, form dry granule layer;
Dry granule layer surface spray methylcellulose gum fixing after enter roller kiln and burn till, firing temperature is 1000 DEG C ~ 1048 DEG C, and the time is 65 ~ 150 minutes, makes work in-process;
(4) the work in-process of kiln discharge are made for finished product after scraping thicknessing, rough polishing, essence throwing, edging, chamfering, air-dry, pick, color separation, classification, and finished product water-intake rate is less than 3, and devitrified glass layer thickness is 0.3 ~ 1.0mm.
As preferably: (2) described operation comprises further:
(2.1) execute ground-coat enamel after green compact drying, base temperature 65 ~ 70 DEG C, with the condition of 300 × 300 pallet unit of measure under water spray 10 grams and the quantity implementing described ground-coat enamel is 300 × 300 pallet unit of measure 60 ± 1 grams, be prepared into glazed body stand-by;
(2.2) after executing ground-coat enamel, glazed body one or more printing ornaments again in digital ink-jet, rubber roll, planography make over-glaze decoration base, then apply dry-type belt material distributing machine, with 1.5 ~ 3.5Kg/m on over-glaze decoration base
2cloth doses charity particle diameter be 80 ~ 200 object transparent glass-ceramics frit dry granulars, form dry granule layer, the spray of dry granule layer surface executes that methylcellulose gum is fixing finally to be entered roller kiln and burn till in right amount.Other index meets JCT994-2006 microcrystallite glass-ceramic composite brick standard.
As preferably: the ground-coat enamel in described operation (2.1) is made up of the component of following weight part:
