Abstract
The invention relates to a production method of a pattern glazed ceramic tile. The production method comprises the following steps: preparing a ceramic tile blank; preparing a color-glazed wrapper on the surface of a clinker; spraying a water repellent layer on the surface of the ceramic tile blank; then, paving and depositing the clinker with the color-glazed wrapper on the ceramic tile blank; then, supplementarily spraying a clinker particle adhesive; and finally, drying, firing and rubbing down to obtain a pattern glazed ceramic tile product. The clinker particle adhesive comprises the following components in percentage by mass: 5.5-6.5% of a cellulose thickener, 2.5-3.2% of white carbon black, 1.1-1.4% of a defoaming agent, 1.2-1.8% of a dispersant and the balance of a solvent. By using the clinker particle adhesive to fix the clinker with the color-glazed wrapper on the ceramic tile blank, the clinker particles which are too small are prevented from being drawn away by a negative pressure of a preheating zone of a kiln, thereby preventing flaws such as massive needle holes and air bubbles on the surface of the tile from influencing the decorative effect of the tile blank.
Description
Technical field
The present invention relates to a kind of building material technical field, particularly relate to a kind of production method of pattern glazed ceramic brick.
Background technology
Along with the development of the frit particle of various decorative effect, application frit particle being distributed in the different decorative effect that adobe is played also more and more is subject to the favor of producer, and its market of bringing also is inestimable.So frit particle is not only applied to glass-ceramic clad plate, and in the production process of a lot of glazed ceramic brick, be also applied to now the decorative effect of frit particle reinforce adobe.But the quality of frit particle directly determines the quality of adobe decorative effect, because the stationarity of glue to clear frit particle is poor, described when firing, too little clear frit particle easily introduces pin hole or bubble, 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, there is interval line in the transparent ice crystallized reason that therefore obtained glazed ceramic brick product is formed, discontinuous, and leave bubble.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 be realized, thus reaches good application.
Summary of the invention
The object of the invention is to the production method proposing a kind of pattern glazed ceramic brick, its problem that used frit particle can be avoided to be siphoned away by negative pressure in kiln preheating zone.
For reaching this object, the present invention by the following technical solutions:
A production method for pattern glazed ceramic brick, its production method comprises the steps:
(1), ceramic adobe is prepared;
(2), by color glaze slip paint frit surface, obtained frit surface forms color glaze integument;
(3), on the surface of ceramic adobe drench one deck hydrophober, then the described frit paving with color glaze integument is amassed on ceramic adobe;
(4), on ceramic adobe, supplement spraying one deck frit granule agglomerant, amass to make paving and be bonded and fixed on described ceramic adobe at the frit of the described color glaze integument on top;
(5), by the ceramic adobe of above-mentioned steps process through super-dry, burn till and rubbing down processing, pattern glazed ceramic brick product can be obtained;
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% to described frit granule agglomerant, and dispersion agent is 1.2-1.8%, and surplus is solvent.
Preferential, described cellulose thickener is at least one in Natvosol, hydroxyethylmethyl-cellulose and Vltra tears.
Preferential, described dispersion agent is at least one in sodium polyacrylate, organic-silicon-modified sodium phosphate and Sodium hexametaphosphate 99.
Preferential, described defoamer is polymethyl siloxane.
Preferential, described solvent is at least one in ethylene glycol and ethanol.
Preferential, the thickness amassing the frit particle with color glaze integument on biscuit upper berth is 1-3mm.
Preferential, the firing temperature in step (5) is 1050-1200 degree, and the time is 90-150 minute.
Preferential, described hydrophober is organosilicon moisture repellent.
The frit with color glaze integument is fixed on ceramic adobe by using frit granule agglomerant by the present invention, avoid frit particle to be sucked away by the lower negative pressure of kiln preheating zone because particle is too little, thus avoid brick surface to occur that the decorative effect of flaw to adobe such as a large amount of pin holes and bubble has an impact.
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.
Preparation-the embodiment 1 of frit granule agglomerant
The component of every 100kg frit granule agglomerant: Natvosol (purchase of Guangzhou Mo Ke building materials Science and Technology Ltd.) 5.5kg, White Carbon black 2.5kg, polymethyl siloxane 1.1kg, organic-silicon-modified sodium phosphate 1.7kg, surplus is ethylene glycol.
The preparation method of above-mentioned frit granule agglomerant, comprises the following steps: a) be dissolved in ethylene glycol by Natvosol, stirs; B) add polymethyl siloxane and organic-silicon-modified sodium phosphate, stir; C) add White Carbon black and residue ethylene glycol solvent, stir and obtain frit granule agglomerant, surveying its flow velocity is 25.7s (30 DEG C, be coated with-4 glasss).It should be noted that, organic-silicon-modified sodium phosphate can use sodium polyacrylate or Sodium hexametaphosphate 99 to replace as dispersion agent also can realize this programme.
