Abstract
The invention discloses a kind of compact zircon brick and preparation method thereof, following components is included: the quartz micropowder of 31% 33%, zirconium oxide micropowder, 0 0.5% organic bond and the additive surplus of 65% 68% according to weight ratio, each component peeked amount sum is equal to 100%, mean diameter D50≤10 μm of described quartz micropowder, mean diameter D50≤10 μm of zirconium oxide micropowder.The compact zircon brick of the present invention has the advantage high-quality, stable, highly purified and impurity content is few.
Description
Technical field
The present invention relates to the synthesis field of refractory material, be specifically related to a kind of compact zircon brick and preparation method thereof.
Background technology
Common zircon brick typically uses zircon sand to produce, by zircon sand being worn into micropowder aftershaping, after re-sintering
It is processed as finished product.And the zircon stone brick material that some purity requirements are higher, the most simply use selected zircon sand, and by pickling,
Produce as raw material after the certain methods remove impurity such as calcining.But it is special that existing zircon stone brick material still can not meet some
The requirement of glass.
Along with the development of glass material, special glass requires more and more higher, and some old zircon materials have been opened
Beginning not catch up with development, its cupric or iron content all severe overweights, impurity does not the most adapt to the requirement of specific glass.
Summary of the invention
In place of it is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of compact zircon brick and preparation side thereof
Method.
A kind of compact zircon brick of the present invention, according to weight ratio include following components: 31%-33% quartz micropowder,
The zirconium oxide micropowder of 65%-68%, 0-0.5% organic bond and additive surplus, each component peeked amount sum is equal to
100%, mean diameter D50≤10 μm of described quartz micropowder, mean diameter D50≤10 μm of zirconium oxide micropowder.
As a further improvement on the present invention, described additive includes that titanium oxide, yittrium oxide, lanthana, cerium oxide, silicon are molten
Glue or waterglass.
As a further improvement on the present invention, described additive include the titanium oxide of 0-1.0%, the yittrium oxide of 0-0.3%,
Lanthana or cerium oxide, the Ludox of 0-1.5% or the waterglass of 0-1.5%, additive also includes the water reducer of 0-0.3%.
The preparation method of the compact zircon brick of the present invention, comprises the following steps:
S1: glass sand and the high-purity mangesium oxide zirconium of buying are calcined respectively, obtains calcining quartz sand and forges
Burn zirconium oxide, SiO in described glass sand2Content >=99.5%, ZrO in high-purity mangesium oxide zirconium2Content >=
99.5%.
S2: calcining quartz sand and calcined zirconia are obtained quartz mud and zirconium oxide mud by ball mill pulverizing respectively.
S3: pass through respectively to dry by quartz mud and zirconium oxide mud, obtains the drying material of correspondence, then by drying material difference
Beat powder；Sieve respectively after beating powder, obtain quartz micropowder and zirconium oxide micropowder.
S4: according to formula proportion quartz micropowder to be asked for, zirconium oxide micropowder, organic bond and additive, carry out mix grinding,
Obtain mixing mud.
S5: dried by above-mentioned mixing mud, obtains drying material and beating powder, sieves, obtain high-purity synthesis zirconium after beating powder
Diamond stone raw material.
S6: above-mentioned high-purity synthesis zircon raw material is carried out high-temperature calcination, obtains high-purity synthesis zircon calcining material.
S7: high-purity synthesis zircon calcining material is carried out ball mill pulverizing, drying, obtains drying material and beating powder processing, obtains
Synthesize high-purity zircon micropowder.
S8: high-purity for above-mentioned synthesis zircon micropowder hydrostatic profile is obtained the raw embryo of compact zircon brick.
S9: raw for above-mentioned compact zircon brick embryo is carried out high temperature sintering, obtains semi-finished product brick.
S10: above-mentioned semi-finished product brick is carried out cold working, obtains compact zircon brick finished product.
As a further improvement on the present invention, in described step S1, calcining heat is 1360-1400 DEG C.
As a further improvement on the present invention, in described step S6, calcining heat is 1350 DEG C-1650 DEG C, the insulation of calcining
Time is no less than 9h；In described step S9, the temperature of high temperature sintering is 1580 DEG C-1680 DEG C, and the temperature retention time of calcining is no less than
12h。
As a further improvement on the present invention, mean diameter D50≤10 μm of described quartz micropowder, putting down of zirconium oxide micropowder
All particle diameter D50≤10 μm.In step S7, synthesize mean diameter D50≤8 μm of high-purity zircon micropowder, need to add during ball mill pulverizing
Enter≤lanthana, yittrium oxide or the cerium oxide of 0.3%, add the bonding agent of 0.2%, add the water reducer of≤0.2%.
As a further improvement on the present invention, described step S3, moisture≤0.4% drying material of S5 and S7, step S3,
S5 and S7 needed 30 mesh sieves after beating powder.
As a further improvement on the present invention, described step S7 needs before starting to carry out high-purity synthesis zircon calcining material
