Description
Technical field
The present invention relates to a kind of Zirconium oxide fibre ceramic wafer, can be widely applied to the field of employment of more than 1500 DEG C and equipment, belong to inorganic adiabator technical field.
Background technology
Along with the development of the rise of the NPD projects such as new work engine and aeronautical and space technology, increasingly exigence material can keep its working strength and modulus under high temperature oxidizing conditions. Zirconia ceramics fiber, owing to having the features such as high-melting-point, higher heat stability, corrosion resistance, thermal shock resistance, and becomes the high-temperature oxidation-resistant material of most research potential. Zirconia ceramics fiber and fiber board products thereof will be widely used in fields such as Aero-Space, guided missile and rocket engine interior trim, atomic reactor, Industrial Stoves, high temperature filtrations.
Restriction due to the current technology of preparing of domestic Zirconium oxide fibre own, the Zirconium oxide fibre intensity of preparation is relatively low, the technology of preparing directly preparing fibre board is more difficult, in published traditional method preparing zirconium oxide fiber board, need to add the materials such as binding agent, flocculant, fortifying fibre, not only complex process, but also introduce other components, reduce zirconium oxide fiber board applied at elevated temperature performance, especially the organic component added at high temperature carbonization, release harmful gas, causes environmental pollution, and personnel when to confined space produce harm. Therefore, seek a kind of simplicity, safety, green, free of contamination zirconia ceramic beaverboard preparation method particularly important.
Summary of the invention
It is an object of the invention to solve the deficiencies in the prior art, it is provided that a kind of zirconia ceramic beaverboard, its serviceability at high temperature is good.
Another object of the present invention also resides in the preparation method providing above-mentioned zirconia ceramic beaverboard, and preparation technology is simple, need not add binding agent and reinforcing material, efficient pollution-free.
For solving the problems referred to above, the technical solution adopted in the present invention is as follows:
A kind of High-temperature-reszirconium zirconium oxide fiber ceramics plate, the thickness of this Zirconium oxide fibre ceramic wafer is 2��30mm, and density is 0.1��0.35g/cm3, described Zirconium oxide fibre ceramic wafer is made up of the Zirconium oxide fibre that fibre diameter is 1��12 ��m.
The preparation method of above-mentioned High-temperature-reszirconium zirconium oxide fiber ceramics plate, comprises the steps:
(1) adopt centrifugal drying wire feed mechanism for zirconium oxide precursor fibre: to be added continuously to get rid of a head by zirconium oxide precursor solution, drive through high-speed electric expreess locomotive and throw away filamentation, collect and obtain zirconium oxide precursor fibre.
(2) zirconium oxide precursor fibre is carried out presintering, obtain the fiber after carbonization.
(3) undertaken discongesting slurrying by the fiber after carbonization, obtain fibre stuff, fibre stuff is poured in molding pond, after stirring, draining successively, vacuum draw, roll-in, obtain the wet embryo of fibre board, namely obtain the fibre board of carbonization after drying.
(4) fibre board of carbonization is carried out high temperature sintering, as required cutting, namely obtain zirconium oxide fiber board.
In step (1), in described zirconium oxide precursor solution, the mol ratio of zirconium oxide, yittrium oxide, magnesium oxide, silicon oxide, sodium oxide, aluminium oxide and calcium oxide is: (80��96): (3��20): (0��10), (0��5): (0��5): (0��1): (0��1), the adjustment of ratio between each component, is the Zirconium oxide fibre in order to obtain Tetragonal or Emission in Cubic. Its preparation method can be synthesized by organic coordination method, it is also possible to is prepared by sol-gal process, and in order to obtain good fibroblast effect, both of which needs to add spin finish aid and is adjusted.
Such as, organic coordination method is adopted to prepare zirconium oxide precursor solution, mol ratio according to above-mentioned oxide calculates the quality of corresponding raw material, in advance yttrium salt, aluminium salt etc. are dissolved in the aqueous solution of spin finish aid, add suitable quantity of water and form uniform glue, again under intensively stirred condition, it is gradually added in the ethylene glycol monoethyl ether solution of solubilized depolymerization acetylacetone,2,4-pentanedione zirconium, forms zirconium oxide precursor solution.
In step (2), the temperature of described presintering is 500��800 DEG C, and temperature retention time is 0.5��2h. The organic component being primarily intended in removal zirconium oxide precursor fibre of described presintering, this process is along with the volume contraction of fiber, owing to whole sintering process also has formation and the transformation of zirconium oxide crystal formation, the same contraction along with fiber volume, sinters the impact on size after the contraction of presintering reduces fibre board molding.
In step (2), described sintering atmosphere is air, nitrogen or steam, and heating rate is 0.5��5 DEG C/min, and heating rate is unsuitable too fast, and speed is too fast, and organic volatile is also fast, and fibre damage is relatively big, and fiber very easily breaks up.
In step (3), the purpose discongesting slurrying is to make fiber rotate in water high speed, bundle fiber is dissociated into ultimate fibre, is only uniformly dispersed by fiber, by fibre cutting, will not will not damage fibre strength. The mass concentration of described fibre stuff is 0.5��2%, and the too small reduction production efficiency of concentration, concentration is excessive affects dispersion effect, causes product density uneven.
In step (3), described baking temperature is 90��110 DEG C.
In step (4), the temperature of described high temperature sintering is 1000��1500 DEG C, temperature retention time is 0.5��5h, described high-temperature sintering process is burnt completely by carbide on the one hand, being the transformation of zirconium oxide crystal formation on the other hand, whole process is the process of fibre board densification, forms more, higher overlap joint between fiber simultaneously, the three-dimensional net structure making fibre board is completely embedded, and imparts the mechanical strength that zirconia ceramic beaverboard goods are higher.
In step (4), it is 5��15 DEG C/min that the heating rate of described high temperature sintering controls, and heating rate is comparatively fast for inhibiting grain growth, it is achieved fiber densification.
The present invention compared with prior art, its remarkable advantage: the preparation method of the present invention be prone to molding, simple to operate flexibly, cost is low, safety non-pollution, the zirconia ceramic beaverboard of preparation has the heat-proof quality of excellence, uses temperature 1500 DEG C.
