Description
Technical field
The present invention relates to a kind of microcrystal glass-ceramic compounded plate and preparation method thereof.
Background technology
Than traditional decorative ceramic board, advantage such as that microcrystalline glass decorative plate has is corrosion-resistant, wear-resistant, water-intake rate is low, but there are problems such as production cost height, complicated process of preparation, kind are single in present crystallizing glass decoration board, is difficult to popularization on a large scale.
Crystallizing glass decoration board commonly used is generally selected CaO-Al for use
2O
3-SiO
2System, CaO-MgO-SiO
2System or CaO-MgO-Al
2O
3-SiO
2The sytull of system, and, usually need in glass, add valuable ZnO, BaO and and Na in order to reach good sintering character and flowing property
2O (or K
2O) be mixed into ZnO+Na
2O, BaO+Na
2O or ZnO+BaO+Na
2Mixtures such as O are as fusing assistant.As being among CN00136831.1, CN1974455A, the CN1433985A at publication number, the add-on of its ZnO, BaO even reach about 10wt% makes that the production cost of sytull is higher.At publication number is among CN101186129A and the CN101186443A, and the artificial sytull production cost that reduces of invention adopts Li
2O replaces fusing assistant ZnO and BaO, but still needs to use the higher Li of price
2O, and its usage quantity is also bigger.Valuable raw material ZnO, BaO, Li
2The effect of fusing assistant has not only been played in the adding of O, thereby and the flowability that can improve glass reduce the thermal treatment temp of glass.
In addition, sintering process at present commonly used prepare sytull generally be with the direct lay of coarse particles frit that obtains after the shrend on ceramic bases, thermal treatment then.It utilize the coarse particles frit to be because still can maintain gloss after bakingout process; But because particle size is bigger, occur the space each other easily, in order to make final sytull densification, thermal treatment temp generally reaches 1100～1200 ℃.Like publication number is that treatment temp all reaches 1200 ℃ among CN101186129A and the CN101186443A.This certainly will improve the production cost of sytull again, and is totally unfavorable for producing in enormous quantities, promoting on a large scale.
Summary of the invention
The technical problem that the present invention will solve provides microcrystal glass-ceramic compounded plate that a kind of cost is lower, glossiness is good and preparation method thereof.
In order to solve the problems of the technologies described above, the present invention provides a kind of microcrystal glass-ceramic compounded plate, and the sytull in this composition board is by major ingredient with as the Sb of finings
2O
3Form Sb

The present invention also provides the preparation method of above-mentioned microcrystal glass-ceramic compounded plate simultaneously, may further comprise the steps:
1), with major ingredient and Sb
2O
3Thorough mixing is even, places stove to be heated to 1450～1500 ℃ and be incubated 3.5～4.5h then, obtains clarifying uniform glass metal;
2), glass metal is poured in the swage into moulding and cooled off 1～2min, in 480～520 ℃ of annealing 0.5～1h down, obtain blocky mother glass afterwards; After half of mother glass pulverized glass powder, second half of mother glass is broken into the glass particle that particle diameter is 0.1～0.3mm;
3), get glass powder and evenly be laid on the conventional ceramic plate, becoming thickness is the glass frit layer of 1～2mm; And then with the glass particle of individual layer (being that glass particle does not produce superposition phenomenon up and down each other) evenly spreading on glass frit layer,, obtain microcrystal glass-ceramic compounded plate through 950～1000 ℃ of thermal treatment 2～3h.
Improvement as the preparation method of microcrystal glass-ceramic compounded plate of the present invention: the glass powder step 2) needed 200 mesh sieves.
The present invention be the contriver on the basis of sytull that studies for a long period of time, obtain through exploring technological process repeatedly.The present invention only adopts Na
2O and K
2O utilizes glass powder to replace coarse particles as fusing assistant, has not only removed valuable oxide compound ZnO, BaO, Li from
2The adding of O, and remedied because of lacking ZnO, BaO, Li
2O and the glass flow property variation that causes have also reduced the thermal treatment temp of glass simultaneously.In addition, the present invention lays glass particle on glass powder, relies on glass particle to handle the glossiness characteristics in back, has guaranteed the surface gloss after the sytull thermal treatment.
In sum, the present invention has following advantage:
The first, preparation sytull desired raw material is cheap raw material, does not contain Li
2The more expensive fusing assistants of price such as O, ZnO, BaO have effectively reduced the production cost of crystallizing glass sheet material, help it and produce and promote on a large scale.
The second, the present invention has combined the glass powder low-temperature heat treatment to be prone to after densification and the glass particle thermal treatment glossiness two specific characters are preferably arranged; The mother glass material is prepared into powder and particle respectively; And be layed in thermal treatment again on the ceramic plate successively; So both effectively reduce thermal treatment temp (minimum only need get final product for 950 ℃), guaranteed the glossiness on sytull surface simultaneously again.
Therefore, the present invention overcome existing microcrystal glass-ceramic compounded plate production cost higher, need to use the heat treated shortcoming of comparatively high temps.
Adopt the microcrystal glass-ceramic plate that the present invention produced, can be widely used in the family decorations such as exterior wall finish and high-grade public place such as airport, hotel, office building.
