Abstract
The invention relates to a microcrystallite glass ceramic composite plate production process, which comprises: applying a powder material and stamping to form a brick billet; forming a bottom glaze layer, forming a printing layer, carrying out first firing, applying frit particles, carrying out second firing, and finally carrying out polishing, edging, inspection and packaging to obtain the finished product, wherein a suspension prepared from the frit particles and a frit particle binder is adopted as a binder, and the frit particle binder contains, by mass, 5.5-6.5% of a cellulose thickener, 2.5-3.2% of white carbon black, 1.1-1.4% of an anti-foaming agent, 1.2-1.8% of a dispersing agent, and the balance of a solvent. According to the present invention, the suspension prepared from the frit particles and the frit particle binder is adopted as the binder, such that the frit particle is prevented from being sucked by the low negative pressure of the kiln preheating zone so as to avoid a large number of pin holes, bubbles and other defects on the ceramic brick surface and substantially improve the integrity and the smoothness of the surface texture of the fired brick billet.
Description
Technical field
The present invention relates to a kind of building material technical field, particularly relate to a kind of glass-ceramic clad plate production technique.
Background technology
Glass-ceramic clad plate is a kind of high-end decorative building material product, it is with glittering and translucent, elegant and poised, self-sow and the exterior decorative effect changing different imitative bag reason, painted level, superb craftsmanship, and not contaminated, be easy to clean, inherent excellent physical and chemical performance, also there is the weather proofing stronger than stone material, weathering resistance and be subject to the favor of domestic and international high-end building materials market in addition.
In the production process of glass-ceramic clad plate, all be unable to do without frit, but the quality of frit particle directly determines the quality of adobe decorative effect, because glue or methylcellulose gum water are all poor to the stationarity of clear frit, described when firing, collocation is needed to use the frit particle of different-grain diameter, otherwise be difficult to pile up closely, and easily there is the defects such as pin hole, what is more important fine particle (being especially less than 100 orders) is easily sucked away due to lower negative pressure in the preheating zone of kiln due to lighter weight, some grain effects in frit layer may be difficult to present because frit is siphoned away by kiln preheating zone negative pressure, and after tiny frit particle is sucked away, outside process grain effect is discontinuous, glass-ceramic layer after burning also has a lot of pin hole, air blister defect.If by adding binding agent again to drench the mode of glaze in frit particle, then surface molecule being all fixed on base substrate can being realized, thus reach good bond effect, avoiding the frit particle tiny when burning till to be siphoned away by kiln preheating zone blower fan.So being badly in need of a kind of frit granule agglomerant of research can well fix frit particle bond, reduces the waste of resource.
Glaze pouring requires to add frit particle and mix afterwards flow velocity with binding agent and, lower than 50s (30 DEG C, be coated with-4 glasss), and can not to precipitate, the solid content of frit particle higher than 60%, but this to be common glue or binding agent be difficult to realization.
Summary of the invention
The object of the invention is to solve in the production process of glass-ceramic clad plate, frit particle is easily by problem that kiln preheating zone blower fan siphons away.
For reaching this object, the present invention by the following technical solutions:
A kind of glass-ceramic clad plate production technique, its production technique comprises the steps:
(1), the punching press of charity powder forms adobe;
(2), form ground glaze layer, then form printed layer;
(3), first time burns till;
(4), by frit and frit granule agglomerant mix, make suspension;
(5), the suspension that step (4) is obtained is imposed on the obtained greenwave of step (3) on the surface;
(6), second time through kiln grand feu make frit particles fuse, cooling can obtain glass-ceramic clad plate work in-process;
(7), polishing is carried out to glass-ceramic clad plate work in-process, edging, inspection, packaging become finished product;
Described frit granule agglomerant its by mass percentage, containing, for example lower component: cellulose thickener 5.5-6.5%, White Carbon black 2.5-3.2%, defoamer is 1.1-1.4%, and dispersion agent is 1.2-1.8%, and surplus is solvent.
Preferably, described cellulose thickener is at least one in Natvosol, hydroxyethylmethyl-cellulose and Vltra tears.
Preferably, described dispersion agent is at least one in sodium polyacrylate, organic-silicon-modified sodium phosphate and Sodium hexametaphosphate 99.
Preferably, described defoamer is polymethyl siloxane.
Preferably, described solvent is at least one in ethylene glycol and ethanol.
Preferably, in step (3), firing temperature is 1120-1230 DEG C, and the time is 90-180 minute
Preferably, described in step (5), firing temperature is 1000-1100 DEG C, and the time is 120-240 minute.
Preferably, the thickness that suspension is spilt on the greenwave upper berth after first time burns till is 1-3mm.
Preferably, in above-mentioned a kind of glass-ceramic clad plate production technique, solid content >=65% of suspension liquid; Preferably the solid content of suspension liquid is 65%-75% further.
In this scheme, the solid content of suspension liquid should not be too high, and too high easy layering sinks to the bottom, nor be difficult to topple over cloth and impose on billet surface.
The present invention makes suspension by using frit granule agglomerant and frit particle, it has good adhesivity, after cloth imposes on base substrate, it can avoid frit particle to be siphoned away by kiln preheating zone blower fan, thus avoid ceramic brick surface and occur the flaws such as a large amount of pin holes and bubble, improve integrity and smoothness that the texture of rear surface is burnt till in adobe greatly.
Embodiment
Technical scheme of the present invention is further illustrated below by embodiment.
The thickening mechanism of cellulose thickener be hydrophobic main chain and surrounding water molecules by hydrogen bond association, improve the fluid volume of polymkeric substance itself, decrease the space of Particle free activity, thus improve system viscosity.Also can be realized the raising of viscosity by the winding of molecular chain, showing as and have high viscosity at static and low sheraing, is low-viscosity under high shear.This is because when static state or low shearing speed, cellulose molecular chain is in state of disarray and makes system present high viscosity; And when high shear rates, molecule is parallel to flow direction and makes ordered arrangement, be easy to mutual slip, so system viscosity degradation.Cellulose thickener, White Carbon black and auxiliary agent are mixed by a certain percentage, can obtain use under neutral environment, have good thickening adhesive effect, the binding agent of not metal ion, be applicable in Building Ceramics Industry and need to be fixed with in bonding operation frit particle.
