Description
Technical field
The present invention relates to a kind of flat glass ceramic body, preferably relate to as the glass ceramic body of hotting plate face with at least one frosted zone.But this flat glass ceramic body also can form by visual sheet glass such as the visual sheet glass of chimney or the visual sheet glass of stove and by lampshade.
The invention still further relates to a kind of method for preparing this class glass ceramic body.
Background technology
The novel district of hotting plate has the glass-ceramic of being hotted plate the district or being hotted plate the position by each of coal gas, induced radiation device or the heating of electirc radiation device usually and hots plate face.
Known glass-ceramic is hotted plate face and is had dark up to black color sensation, in particular for guaranteeing hotting plate the required not visible property of intra-zone usually.This can realize by the painted of the glass-ceramic raw material in melt or by the lighttight colored coating of corresponding glass ceramic plate bottom surface.
Originally apparent the glass-ceramic that had a continuous unanimity is hotted plate face needs some mark usually, also can be described as decoration, to increase its application target, marks in the zone in whole hotting plate typically and hots plate the district.This mark can be made by diverse ways.The method that the present invention uses is to produce the frosted zone, its visually significantly from around hot plate the zone and highlight because the zone of hotting plate on every side is that non-ordinary light is sliding and be bright therefore.
By prior art usually can by surface sand-blasting or with the hydrofluoric acid corrosion surface make glass or glass-ceramic frostedization (
Chemie Lexikon, Ausgabe 08/2003: " Mattieren von Glas ").This surface apparent can be when sandblast by select abrasive particle (as at Japanese patent abstract Nr.2001062727A with described in the EP 1236696A) when corrode with hydrofluoric acid by different compositions (as described in the DE 3122133A1) or by glass ink as changing the action time by the mixture of barium sulfate, ammonium sulfate, hydrofluoric acid.
These two kinds of methods all can not be particularly well suited to the frostedization that glass-ceramic is hotted plate face.Because hydrofluoric acid vapor is hypertoxic, and need to avoid as far as possible aborning.In addition, if only need hotting plate some regional frostedization of face, then this corrosion and sandblast need be taked expensive mask measure.
The frosted that glass-ceramic is hotted plate face as by from around the frosted of hotting plate the district of hotting plate the frosted ring that highlights the zone mention at EP 0464323B1.This frosted zone produces by material corrosion by means of laser, and this is very expensive under than the big area situation.
According to Japanese patent abstract Nr.57107271A, another possibility that produces the frosted district on heat-stable material is, will wherein be added with filler such as ZnO or SiO
2Thermosetting resin be applied on this material and sclerosis.But this resinoid thermotolerance is 400 ℃ to the maximum, so that this coating only is suitable for remaining on the zone that the glass-ceramic under the cold operation (being lower than 400 ℃) is hotted plate face.
Another kind of situation particularly starts the flat glass ceramic body of mentioning also similar problem.
Summary of the invention
The objective of the invention is to, producing on the flat glass ceramic body can be with frosted zone not only simple on technology but also that not dangerous mode is made, and high heat request and mechanical requirement can be born in this zone in the use of flat glass ceramic body.
This purpose solves by following method by the present invention under the flat glass ceramic body situation at least one frosted district having, promptly this frosted district is formed by the glass coating that is frosted shape fusing on glass ceramic material, this frosted shape molten glass have greater than 750 ℃ high softening-point with have the specific refractory power different with glass ceramic material.
On method, the objective of the invention is to realize that by method this method comprises the following steps: by the aforesaid flat glass ceramic body of glass body preparation
The bonding glass powder of the frosted shape molten glass of preparation on the glass ceramic material, this glass have greater than 750 ℃ high softening-point with have the specific refractory power different with glass ceramic material,
With this bonding glass powder be coated on the glass base substrate or by its glass ceramic body of making at least the one side on the zone of wanting frostedization,
With
The bonding glass powder that roasting should be coated with in the independent heating steps when being coated with during the Vitrea potteryization of base or on the glass ceramic body in potteryization.
This independent heating steps can be promptly to melt this glass powder as roasting to fuse through formation in 20 minutes under 850-900 ℃.
Just can obtain a kind of flat glass ceramic body by measure of the present invention with simple process and not dangerous preparation process with frosted district, because the glass performance of coating, high heat request and the mechanical requirement under the face of hotting plate moves especially can be born by this frosted district, and visually can obviously aware this frosted district by the difference on specific refractory power.
Also can carry out complete surperficial frosted to this flat glass ceramic body handles.This frosted meeting changes the whole sense organ of glass ceramic body.Less finger mark and little injury (cut etc.) appear.
Have than high softening-point (E
W=750-850 ℃) borosilicate glass (be as the trade mark
) show it is particularly suitable.This softening temperature E
WCharacterizing by temperature, is 10 in the viscosity of this temperature lower-glass
7.6DPas.
In addition, this borosilicate glass also should have the specific refractory power different with glass-ceramic.The difference of preferred this specific refractory power is greater than 0.03.
Selecting another important factor of glass for use is thermal expansivity.This thermal expansivity should be lower than 710
-6K
-1, so that this coating can stick on the glass-ceramic satisfactorily.Special preferably this glass has low especially thermal expansivity, in DE 19643807C2
3.3 thermal expansivity only be 3.310
-6K
-1, because have the glassy phase ratio of higher thermal expansivity with application, low thermal coefficient of expansion makes through the strength degradation of the glass-ceramic of coating obviously still less.Using the mat glass pottery when hotting plate face, this intensity of hotting plate the high as far as possible anti-tensile stress above the face is as being favourable when assembling of hotting plate face or the transportation.
If glass is through fine grainding (d
99＜10 μ m) exist with slurry in common silk screen printing medium, then this glass coating can be finished with silk screen printing.The known melted glass that is generally used for decorating look is formed (as mentioning) in DE 19721737C1, DE 19834801C2, DE 4201286C2 be inapplicable, because this class glass has too low softening temperature (E
W＜750 ℃), and its specific refractory power adapts to common glass-ceramic, therefore is the clear transparent fusing.
Based on described method, not only can make the black glass pottery, and can make coloured (as blue, white, faint yellow) or flint glass pottery frostedization.
If use special fine grainding
3.3 (d
99＜4.5 μ m), then can obtain velvet shape frosted sense organ especially uniformly as borosilicate glass.This borosilicate glass that does not almost have the fine grainding of agglomerate can be realized by grinding in being added with the water of Virahol, or realize by (in antiknock device) grinding in pure Virahol.

The specific refractory power of glass
(measuring method: the vee-block method)
This coating potteryization this in the manufacturing stove of continuously operation in reaching under about 900 ℃ (pressing DE19721737C1) through roasting.Bed thickness after the potteryization is 2.5-3.5 μ, because the black of glass-ceramic, it is apparent that this coating has velvet-like frosted black.Color measuring by the CIELAB system shows, be unexpectedly owing to the coating that does not contain pigment cause black tone intensification (under glass-ceramic situation through applying, L
*Value is obviously lower): the colour of the glass-ceramic of uncoated is L
*=24.8, a
*=-0.1, b
*=-0.6.The colour of the frosted black glass pottery through applying is L
*=22.3, a
*=0.1, b
*=-0.8.The reflectivity i.e. reflected light at 90 ° of angles is that the vertical incidence of the visible light of 400-800nm is measured by wavelength.The reflectivity of the glass-ceramic of uncoated is 10-11%.On the contrary, this reflectivity through the frosted regions coated only is 6-8%.
The service performance of this coating is very good.
Adhesion strength by means of transparent adhesive film (
Typ104 Fa.Beiersdorf) measures.This glued membrane band is firmly pressed and tear rapidly.Do not stay coating particles on band, promptly this layer has extraordinary adhesion strength.
Acid resistance is to test through 4 hours under boiling temperature with 4% acetic acid.After this test with the visual variation of not observing out coating.
Flexural strength through the glass-ceramic of whole coating is 70-75MPa (mean value is pressed DINEN 1288-5 and measured).The flexural strength of the glass-ceramic of decorating with common some shape web plate is 88-105MPa according to fraction of coverage.This fraction of coverage is 4% or 19%, decorates the long 0.48mm of being in edge of point.
For comparing, above-mentioned web plate (having the whole finishing coat of 100% fraction of coverage, the close some web plate that has rare some web plate of 4% fraction of coverage and have 19% fraction of coverage) has also been measured the intensity that known glass flux (no pigment) is decorated in EP1119524B1 glass-ceramic is hotted plate face.The flexural strength of pressing DIN EN 1288-5 mensuration is 88-100MPa under a web plate situation, be 70-75MPa under whole finishing coat (100% fraction of coverage) situation.
The intensity that is the glass-ceramic that frosted applies is apparently higher than so far common strength level (mean value by the whole finishing coat of DE 19721737C1 is 33-35MPa), and identical with the order of magnitude of decoration look required for protection in EP1119524B1.
In addition, the cleaning characteristics of institute's coated surface is checked, wherein will be become carbide by the mixture roasting of various food (soup juice, pudding powder, flour, milk, egg, oil), use then commercially available clean-out system (as
Fa.Henkel) remove.There is not perceptible food debris to be retained on the glass-ceramic of decoration in this test, that is to say that this coating has excellent cleaning characteristics through roasting.
Described at FR 2732960, the extremely overcritical material of the mixture that employing is made up of meat soup, egg, milk, sugar, flour, cheese, sago and tamato sauce, at glass ceramic board with hotted plate between the pot roasting 10 minutes, this coating decorates to compare with common glass-ceramic has better tolerance with it.Under common decoration situation, after 1-2 revision test, just stayed the vestige that significantly can not remove again, and frosted coating even suitable damage situations is just arranged when repeating for the third time.
Acid resistance of measuring by common known standard method and alkali resistance and wearability show that also frostedization of the present invention has satisfied the requirement that glass-ceramic is hotted plate the ornament layer of face.In addition, in the glass-ceramic in being the frosted regions coated finger-marks there is obviously little demonstration through frostedization.
In addition, measure the roughness in frosted of the present invention zone, and contrast with the roughness of known decoration look.It the results are shown in following table 1 and is shown in the shape appearance figure of Fig. 1-5.
Table 1: the roughness of decorating look
In order to measure roughness, by DIN EN ISO 4288 usefulness optical means (instrument FRT
) measure per 5 profiles with the detection span of 5.6mm, and press the roughness value that DIN EN ISO 4287 calculates the band associated standard deviation by shape data.
The roughness in the zone of this frosted is R
a=0.51 ± 0.05 μ (Fig. 1).This R
aValue is positioned at the common scope (R that decorates look
a=0.3-0.6 μ, table 1), but it is obviously greater than slick especially decoration look (R
a≤ 0.35 μ, Fig. 5).
But be that the zone of this frosted touches up unexpectedly also is slick, altogether and also anti-galling (it is easily produced by pot or pan on coarse decoration look).This can be explained by the configuration figure of the configuration figure of the coarse common decoration look shown in the comparison diagram 1-5 and novel frosted coating.At this moment tangible difference appears on surface property: at the pornographic condition lower convexity of common coarse decoration broad (about 30-80 μ) and slightly (Fig. 2-5), and this projection is aciculiform (the about 10-20 μ of width) under frosted coating situation of the present invention, and mutual close neighbour (Fig. 1).Therefore the smooth property of frosted coating of the present invention may be made up of the fine needle point of very many tight adjacent arrangements owing to this surface.
The trade mark is CERAN
The black glass pottery be described among the WO 02/16279A1, its disclosure is drawn this.
