A kind of abrasion-resistant clear glaze and the method using its preparation throwing glazed brick
Technical field
The present invention relates to architectural pottery technical field, particularly relate to a kind of abrasion-resistant clear glaze and use it to prepare
The method throwing glazed brick.
Background technology
Throwing the building and ornament materials that glazed brick is a kind of top grade, it refers to have glaze layer on adobe surface, by throwing
It is become the product with gloss or matte effect by light, and some of which goods use clear frit, at glaze
Having texture under Ceng, texture can be realized by known various decorative means, the texture that such as cloth is formed,
The texture etc. that stamp is formed.
But because current glaze wearability is a relatively hang-up of frustration industry.As floor decorative material
Time, the anti-wear performance of glaze is had bigger requirement, is otherwise easy to mill flower, although this point is more existing
Crystallite glass composite plate has bigger improvement, but the anti-wear performance of existing glaze is not met by demand.
To this, some enterprises are solving this problem by the mode thickening glaze layer, but along with glaze layer thickeies, for
Adobe surface has the product of printed layer and has certain impact, thickeies along with glaze layer simultaneously, also increases and be manufactured into
This, and because it needs rubbing down, thick glaze layer can close some bubbles, these bubbles are in rubbing down process meeting
Presenting, appearance and antifouling property to end product impact, and this thickening glaze layer
The problem that mode is also only capable of alleviating glaze anti-wear performance difference.
Summary of the invention
The problem proposed for background technology, the present invention provides a kind of abrasion-resistant clear glaze, by glaze
Use white fused alumina to improve its anti-wear performance, use substantial amounts of spodumene as flux simultaneously, improve glaze
Spreading property, and then make glaze the most smooth, solvent use zinc oxide to improve after glaze burns simultaneously
Transparency, and being used in mixed way by white fused alumina and zinc oxide, solve glaze layer transparency and wearability
The contradiction of energy.Possibly together with a small amount of zirconium in above-mentioned wear-resisting glaze, by zirconium to be converted into zirconic percent mass
Ratio, mass percent need to be less than 0.2% in glaze for zirconium oxide, and general consumption is the 0.1-0.2% of raw materials quality.
A small amount of zirconium can improve the anti-wear performance of glaze layer, is also unlikely to affect the effect of glaze layer simultaneously, the most right
In needing to decorate under display glaze layer the clear frit of texture, this point is particularly important.
A kind of abrasion-resistant clear glaze, its raw material includes following component by mass percentage: 10~20% frit,
10~20% potassium feldspar, 15~40% spodumene, 5~20% burn Talcum, 8~15% brium carbonate, 10~20% wollastonite,
5~10% Kaolin, 0.5~5% white fused alumina, 5~10% zinc oxide, 0.1~0.2% zirconium oxide.
Above-mentioned frit can use known preparing ceramic clinker, and it is mainly flux effect.It is, of course, preferable to for having
There is the functional frit of improved function, such as: for promoting its anti-wear performance, it is possible to use High-Alumina wear-resisting
Frit, is more highly preferred to the raw material of frit and includes following component according to mass percent: 20~30% potassium feldspar, 3~6%
The raw Talcum of wollastonite, 4~8%, 5~8% brium carbonate, 15~20% calcite, 18~22% quartz, 10-14% oxygen
Change aluminum, 2~4% zinc oxide, 1~3% potassium carbonate, 1~2% strontium carbonate.
Frit is as a kind of flux, it is also desirable to it has higher anti-wear performance, therefore makes in this component
Use larger amount of aluminium oxide, and use rare earth carbonate and zinc oxide as flux, make frit have higher
Transparency and anti-wear performance, and the use of carbonate, in frit melting process can abundant aerofluxus, nothing
CAB is in frit, and this is further such that grade free of pinholes is because of the defect of exhausting problem in subsequent clear glaze layer.
In the clear frit provided in the present invention, using strontium carbonate in its frit, addition is 1~2%,
While not increasing the porosity of glaze layer, the wearability of clear frit can be effectively improved, improve clear frit further
Toughness and hardness, and also improve the melting behaviour of high temperature cover-coat enamel, it is thus achieved that the good transparency and gloss
Degree.
In order to make above-mentioned frit have more preferable using effect, its glass melting temperature in the preparation is
1450~1550 DEG C.Glass melting temperature is too low, it can be made to melt insufficient, and glass melting temperature is too high, can waste the energy.
The present invention also provides for a kind of method using the preparation of above-mentioned glaze to throw glazed brick, by above-mentioned glaze charity at base
Surface, enters after kiln burns till, and carries out rubbing down processing and obtains and throw glaze brick product.
Preferably, in above method, can decorate base substrate before charity glaze, described decoration can
Think any one or the combination in stamp, charity dicoration glaze, charity dry granular frit.
Preferably, in above method, stamp is ink-jet printed.
Preferably, in above method, before charity glaze, base substrate can be carried out rubbing down process.
Glazed thickness≤the 0.5mm throwing glaze tile product preferably, in above method, after rubbing down processing.Relatively
Thin glaze layer, so that the decorative effect on base substrate is preferably presented, and is obtained relatively by rubbing down
Thin glaze layer, can avoid bubble therein, needle pore defect, has preferable antifouling property.
Preferably, in above method, the abrading block hardness that rubbing down processing is used is higher than corundum.
