Description
Technical field
The present invention relates to a kind of full porcelain tooth porcelain glass dust and preparation method thereof, the glass dust prepared has transparency
It is high, the advantages of fracture resistance is good, acid resistance is good, is mainly used in dental all-ceramics and repairs field.
Technical background
Full porcelain tooth material since clinical practice, has been developed into folded from initial monolayer material since the last century the eighties
Layer composite, oxide ceramics is developed into from glass ceramics；Processing technology from porcelain, cast growth be CAD
With the precision cutting technique of processing.Present all-ceramic prosthesis has been provided with good marginal and preferable mechanical property
Can, it disclosure satisfy that the Dental Erosion requirement of the overwhelming majority.All-ceramic material is according to its outstanding aesthetic and good bio-compatible
Property and the extremely favor of oral restoration doctor and many patients, are increasingly becoming most popular dentistry repair materials attractive in appearance.
The main flow of All-ceramic material is lamination composite ceramics, i.e., be made up of substrate porcelain and decorations porcelain two parts, substrate porcelain makes complete
Hat meets the intensity requirement of dummy in porcelain, and good marginal, the decorations porcelain of outer layer are provided by appropriate process technology
Anatomic form and aesthetic to recover dummy.
The structure and mechanical property for adoring enamel coating directly affect the intensity of whole all-ceramic prosthesis.Physical chemistry between material
The matching of performance directly affects interface quality, is related to the stability and service life of all-ceramic prosthesis.
Full porcelain tooth glass dust is that a kind of white glass powder forms one layer thoroughly after plastic-coated is sintered on ceramic false tooth
Bright glass modification face.The vitreum is the outermost material of ceramic false tooth, and its main effect is that the ceramic tooth of modification is rough
Surface, protection dentin layer and adamantine layer；Ceramic tooth is set to show stereovision, more attractive access expansion tooth true to nature.Its performance is straight
The quality of the ceramic tooth of influence is connect, is to make the indispensable material of ceramic tooth.
K, Na content are high in the tooth modification glass frit component that artificial tooth factory of the country generally uses at present, cause glass dust
Chemical stability and acid resistance are poor, thus exploitation has the wide market space without K, Na low temperature glass facing glaze.
The content of the invention
The present invention is by using Y2O3Substitute K2O and Na2O provides a kind of full porcelain tooth porcelain glass dust and preparation method thereof.Should
Goal of the invention is to overcome the shortcomings of current product transparency is low, easily spring porcelain, acid resistance are poor.
The present invention is achieved through the following technical solutions：
The present invention provides a kind of full porcelain tooth porcelain glass dust, including SiO2、Al2O3、B2O3Etc. component, it is characterised in that glass
Glass powder also includes Y2O3Li2The fluxing components such as O, each component mass percentage content is：
It is an object of the invention to provide a kind of full porcelain tooth porcelain glass dust and preparation method thereof,
Comprise the following steps：
(1) calculate by mass percentage and weigh each raw material, prepare compound；
(2) by mixed material heating melting, its smelting technology is to be incubated 20 minutes from room temperature to after 650~700 DEG C, then
1350~1450 DEG C are heated to, 120~180 minutes are incubated, to ensure that each component is fully melted and reacted；
(3) glass metal obtained by step (2) is poured into water quenching in deionized water, it is small that glass metal forms glass by drastically cooling
Particle；
(4) 30 minutes are incubated at 100~150 DEG C, the frit after drying water quenching；
(5) the water quenching frit after drying is milled to the glass dust that particle diameter is 3~5 μm with planetary ball mill.
Y2O3Introducing, both improved the reactivity of raw material；The fracture resistance of vitreum is significantly increased again.Meanwhile, Y2O3
With obvious cooling function, K can be replaced2O and Na2O。K2O and Na2O has the performance of reduction firing temperature, but substantial amounts of
Addition can cause the reduction of glass dust acid resistance.Use Y2O3Replace K2O and Na2O, in the thermal coefficient of expansion and base of control vitreum
While bottom porcelain keeps matching, the acid resistance of glass dust can be obviously improved.
Li2O introducing can reduce the melting temperature, viscosity and thermal coefficient of expansion of glaze.At the same time it can also improve the resistance to of glass
Acid, wearability and glossiness.
The advantage of the invention is that：Add different content rare-earth oxidation yttrium, existing glass system is adjusted and
It is modified, make glass dust that there is preferable fracture resistance, have good matching with matrix material.Use Y2O3Substitute K2O and Na2O
Afterwards, it is obviously improved the acid resistance of vitreum.Have after the full porcelain tooth glass powder sintering of the present invention with all-ceramic prosthesis base material
Good matching and stability.The glass dust transparency is high, acid resistance is good, fracture resistance is good, sintering range is wide and system
Standby technique is simple, can be widely applied to the decorations porcelain field of full porcelain tooth, import substitutes.
