Description
Technical field
The present invention relates to architectural pottery technical field, particularly relate to a kind of frit granule agglomerant and preparation side thereof
Method.
Background technology
Along with the development of the frit granule of various decorative effects, frit granule is distributed in the difference played in adobe
The application of decorative effect the most increasingly favored by producer, its market brought also is inestimable.Mesh
Before, mainly in billet surface or glaze, it is coated with certain thickness frit granule (granule by distributing mode
Size is at 15-150 mesh), and spray one layer of fixative and granule is fixed on billet surface, to glaze after burning till
Reprocessing, the quality of frit granule directly determines the quality of adobe decorative effect, in production, the least
Granule be readily incorporated pin hole or bubble, what is more important fine particle (especially less than 100 when burning till
Mesh) easily it is sucked away due to lower negative pressure in the preheating zone of kiln due to lighter weight.If by frit
Granule adds binding agent again in the way of pouring glaze, then can realize being each attached to molecule the surface of base substrate,
Thus reach well to apply.So, it is badly in need of a kind of frit granule agglomerant of research and connects small frit granule,
Use modes such as drenching glaze by the application of small frit granule and actual production, reduce the waste of resource.
Glaze pouring requires to add flow velocity after frit granule mixes with binding agent and is less than 50s (30 DEG C, be coated with-4 glasss),
And can not precipitate, the solid content of frit granule is higher than 60%, but this is common glue or binding agent difficulty
With realize.The most domestic research to frit granule agglomerant is fewer, the rare product that market occurs
Also various limitation is presented.So work out add frit granule after good fluidity, suspension is excellent and admittedly contains
The binding agent that rate is high will have wide market prospect.
Summary of the invention
It is an object of the invention to solve small frit granule all can on-fixed asking in base substrate or glazed surface
Topic proposes a kind of frit granule agglomerant and preparation method thereof.
For reaching this purpose, the present invention by the following technical solutions:
A kind of frit granule agglomerant, its by mass percentage, containing following component: cellulose family thickening
Agent 5.0-6.0%, attapulgite 2.5-3.0%, defoamer is 1.1-1.4%, and dispersant is 1.7-2.1%,
Surplus is solvent.
Preferably, described cellulose thickener is hydroxyethyl cellulose, hydroxyethylmethyl-cellulose and hydroxypropyl
At least one in ylmethyl cellulose.
Preferably, described dispersant is in sodium polyacrylate, organic-silicon-modified sodium phosphate and sodium hexameta phosphate
At least one.
Preferably, described defoamer is polymethyl siloxane.
Preferably, at least one during described solvent is water, ethylene glycol and ethanol.
The preparation method of frit granule agglomerant as claimed in claim 1, it comprises the following steps:
A), cellulose ethers thickening agent is dissolved in partial solvent, stirs；
B), continuously add dispersant and defoamer, stir；
C), add attapulgite and residual solvent, stir, obtain frit granule agglomerant.
Need exist for explanation, because cellulose thickener is difficult to dissolve, needs long agitation, generally stir
Time of mixing, less than 5 hours, furthermore it is also possible to be first submerged initially in partial solvent by cellulose thickener, puts
After putting more than 24 hours, add in remaining solvent and stir, so can shorten mixing time, fall
Low stirring energy consumption.
Preferably, the using method of above-mentioned frit granule agglomerant, comprise the following steps: by frit granule with
Frit granule agglomerant mix homogeneously, impose on billet surface or first after the good frit granule of billet surface cloth again
At its surface spraying frit granule agglomerant.
The frit granule agglomerant of the present invention is applicable to the less frit granule of granule (100-200 mesh), in system
During standby Ceramic Tiles, it is to avoid frit granule owing to granule is the least by the lower negative pressure of kiln preheating zone
It is sucked away, thus avoids ceramic brick surface and the flaw such as substantial amounts of pin hole and bubble occurs.
The frit granule agglomerant of the present invention solve the to know clearly suspension of frit granule, stability and mobility is asked
Topic.After using frit granule agglomerant of the present invention, frit granule is less than up to more than 60% solid content, flow velocity
50s (30 DEG C, be coated with-4 glasss), suspension, stability and good fluidity, persistently use and do not have bubble.
Detailed description of the invention
Technical scheme is further illustrated below by detailed description of the invention.
The thickening mechanism of cellulose thickener is that hydrophobic main chain passes through hydrogen bond association with surrounding water molecules, improves
The fluid volume of polymer itself, decreases the space that Particle free is movable, thus improves system viscosity.
The raising of viscosity can also be realized by the winding of strand, show as there is high viscosity at static and low sheraing,
It is low-viscosity under high shear.This is because when static state or low shearing speed, cellulose molecular chain is in unordered
State and make system present high viscosity；And when high shear rates, molecule is parallel to flow direction and makees row in order
Row, it is easy to mutually slide, so system viscosity degradation.By cellulose thickener, attapulgite and auxiliary agent
Mix by a certain percentage, can prepare use under neutral environment, have good thickening adhesive effect, do not contain
The binding agent of metal ion, is applicable in Building Ceramics Industry need to be fixed frit granule with bonding
Operation in.
Preparation-the embodiment 1 of frit granule agglomerant
The component of every 100kg frit granule agglomerant: (the unconcerned gram building materials science and technology in Guangzhou is limited for hydroxyethyl cellulose
Company buys) 5.0kg, attapulgite 2.5kg, polymethyl siloxane 1.1kg, organic-silicon-modified sodium phosphate
1.7kg, surplus is water.
The preparation method of above-mentioned frit granule agglomerant, comprises the following steps: a) be dissolved in by hydroxyethyl cellulose

(30 DEG C, be coated with-4 glasss).It should be noted that organic-silicon-modified sodium phosphate can use poly-as dispersant
Sodium acrylate or sodium hexameta phosphate are replaced and also can be realized this programme.
Preparation-embodiment 1-1 of glazed tile
By transparent ice crystal frit granule (buying from Zibo Boshan gold light colour glaze factory, fineness 100 mesh) cloth
In in the billet surface of revenue stamp process, then spray the frit granule agglomerant that one layer of embodiment 1 prepares,
Send in kiln and burn till at 1100 DEG C, edging chamfering, obtain having be uniformly distributed, the glaze of complete ice crystal texture
Face brick finished product.At this it should be noted that the pebble frit granule that the present embodiment 1-1 selects is sintering
During sprawl, cover coat is formed argenteous ice crystal textured pattern, frit granule can pass through
Colour glaze company buys and obtains, and similar frit product also can realize this programme.
Comparative example 1-2
By the pebble frit granule cloth identical with embodiment 1-1 in the billet surface through revenue stamp process
On, then one layer of viscosity aqueous slurry being configured to by methylcellulose of spraying, send in kiln, at 1100 DEG C
Burn till, edging chamfering, obtain the glazed tile finished product with ice crystal texture, but texture exists a small amount of naked eyes can
Seeing pin hole, the seriality of ice crystal texture is the strongest.
Can be compared with the glazed tile end product quality of comparative example 1-2 by embodiment 1-1 and draw embodiment
