Background technology
Using floating process, horizontal drawing technique, lattice-method process, press over system technique, the modern flat-panel building of calendering technology production
With industrial plate glass, such as (1) Door for building, window, cladding glass, (2) automobile and ship glass, (3) high ferro glass
Glass, (4) LCD display glass, (5) PDP display screen glass, (6) TFT display screen glass and smart mobile phone and iPad's is high-strength
Face glass, (7) artistic glass etc. are spent, it has significant deficiency on the formula of production technology, there is a kind of technology prejudice, entirely
Silica composition is all melted using sodium oxide molybdena or boron oxide composition, traditional technology in melting process, to eutectic into
Part composition, have technology prejudice and limit to its be confined to silicon, calcium, magnesium, aluminium intrinsic component, and add 13% or so oxygen
When changing the boron oxide of sodium or 8-15% or so, but viscosity is still very high, dare not more add a large amount of aluminum oxide compositions to lift production
Product intensity and annealing point, because of that if will make the production at a temperature of the uncontrollable more high viscosity of product of prior art
Product quality and yield, and energy-saving effect is very poor, and intensity is also poor, and especially boron composition largely volatilizees, and makes all existing alkali-free boron
Glass production has serious environmental problems.
(1), existing alkali-free boron glass technology, the nothing of especially representational US2002/0011080A1 LCDs
Alkali glass, in composition technical scheme, its proprietary material points out that silica reaches 40-70%, in all actual this kind of products
In boron glass and embodiment, the ratio of silicon is all in as many as 60-70%, and boron oxide content is 5-20%, in practice, oxygen
Changing boron, content reaches 8%-15% in the product.Boron oxide is mainly reached fluxing purpose by it to substitute sodium oxide molybdena composition, and
Such as more than 8% boron composition, 2-3 times is just must be added on raw material, has to add 25- if the glass of 10% Boron contents
The raw material (because most of can be changed into toxic gas volatilization in high temperature) of the content of 30% boron oxide.One of its technological deficiency
It is that its silicone content is too high, is extremely difficult fusing；The two of its technical defect, are that can cause the heavy damage of environmental protection；Its technology lacks
Three fallen into are, when boron composition reaches 5-20%, can be molten bath heavy corrosion (so all present TFT liquid in real production
Crystal display high boron glass molten bath one-year age will cold repair, this has resulted in work efficiency, the serious problems of cost.Especially exist
When producing flat panel Liquid Crystal display screen boron glass, and the composition of boron is too high, in the case of same alumina content, can make
Intensity declines one times；And all existing liquid crystal display panel glass, due to the high content of boron, it can only be produced with press over system,
Its yield only 6-10 ton days, are less than 5% production capacities of floating process (such as 150 minimum ton days).And only one bar 6-
The press over system production line of 10 ton days, equipment cost is also higher by 2-3 times than the float glass line of 150 ton days.So how in liquid crystal glass
In glass production, cost declining simultaneously greatly improves efficiency, can the ability cold repair in 10 years as common float glass technology, and reduce viscous
Degree, energy-conservation, the industry problem for extremely thirsting for solving into people.
(2), existing calcium sodium plate glass, such as [1] Door for building, window, cladding glass, [2] automobile and ship glass,
[3] high ferro glass, [4] PDP display screen glass, [5] artistic glass etc., due to the understanding limitation to its melt composition, found
With high son 150C-200C of the present invention of viscosity temperature in row's bubble homogenization process, energy consumption greatly, per kilogram energy consumption up to 1500 kilocalories or
Up to more than higher than 1500 kilocalories.
(3), in vehicle glass, the application of bullet train glass, the rupture strength of existing industrial glass product, anti-impact
It is also that can not reach very high request to hit performance, and safety guarantee is not high if vehicle glass intensity difference, boat glass often have by
There is very big gap in the accident that wave is broken up, the requirement level especially on vehicle glass to shock resistance.
(4), because the rupture strength of existing industrial glass product is low, (typically in 50MPa or so, some 50MPa are not
To), shock resistance is worse, so in the glass applications of the window of aircraft forward and left and right, to add it is very thick, thus
Weight is increased, the deadweight of influence aircraft has an effect on the definition of sight.
(5) and in the application of building, because the annealing point of existing glass product is low and limitation of its strength character, its
Using scope also by great limitation, also oriented lightening, high intensity, the necessity developed in energy-conservation.
(6), prior art flame resistant glass or have rises suddenly stove glass sheet, stove glass or micro- glass stove glass and the kitchen of temperature
Or dinner table face glass, the expansion rate of existing calcium soda-lime glass do not have the linear character of excellent uniform rising and decline, viscoelastic
Property change greatly, have the defect easily burst, so the application existing defects of this respect.
(7), in addition, a kind of existing Publication No. CN1053047A's " has the crystallization of natural-marble-like surface patterns
Glass and its production method " patent application, its technique is just determined and determined on its inevitable product defects, rather than product composition
Its product defect.

And frit is fuse with one another-combines, frit size ... is controlled, obtaining has marble, the outward appearance of granite decorative pattern.And
And this file has the mould frame of the statement of mass crystallization technical process, it is seen that it uses particle and glues a kind of brilliant color of liquate
The technique of firework line devitrified glass.
What its chromatic pattern and opaque product feature were apparently not determined by material composition, stated by application documents
Process in add determine the crystal of its product, colour He Hua Pattern, institute from each glass particle surface to internal
Crystal is all overgrowed with its each particulate material from outside to inside, is never transparent, good 65%- is not likely to be breached
95% visible transmission than product, and need to overcome these blocks to fall into.

From sample 1-9, because iron, barium, titanium are in certain limit, it is seen that transmittance is 40-95%, adapt to various
Bright glass is used, and sample 10,11, because iron content is 1 to 1.3, and have higher barium monoxide, titanium oxide content and can become
Into opaque brown yellow or brown color, to adapt in features such as intensity, viscosity temperature and strain points all than prior art flat board glass
Glass well it is many it is again complete can be as the high-quality wall ground innovated, curtain-walling section and furniture especially under the opaque window of exterior wall
Flawless finish plate glass material application.
Table 2 lists the glass formula of some prior arts and the performance of correlation.From table 2 it can be seen that being primarily due to four
Boron, iron, the scope of sodium and the present invention for planting sample are different, and due to the ratio between silicon and calcium and calcium oxide and magnesia
Specific proportions relation of the example relation all with the present invention is entirely different, the ratio of its silica and calcium oxide and calcium oxide and magnesia
Example is higher by the present invention significantly, and ratio of the invention is 1.2 times -1.6 times of magnesia for calcium oxide, silica is calcium oxide content
1.9 times -4.1 times, and the silica of these products is all completely different than the content of magnesia than calcium oxide and calcium oxide
's.As seen from Table 2 its technically always all using silicon be as glass skeleton and be melted and also the matrix that is infusibility, so
Its viscosity, especially 100.5(Pa Sec), 101Melting process temperature when (Pa Sec), using standard rotation viscometer all
Do not measure at all (because its viscosity is too high), it is seen that it will overcome energy consumption in fusing, overcome quarrel point, calculus, improving production efficiency
Difficulty it is larger or very big.It is in normal exhaust bubble and be homogenized 102Temperature when (Pa Sec), also than the table 1 of the present invention
Sample is higher by 150 DEG C -300 DEG C, it is seen that its be vented and homogenizing difficulty, and the present invention technique hand platform energy-conservation and ratio easy to control
Compared with advantage, for the moulding process temperature of 103 (Pa Secs), the present invention is for shaping, flatness, thickness difference for product
There are the manageable comparative advantages of very big technology, and in terms of product strength, inventive article is also its 2-3 times, linear
The coefficient of expansion, when being particularly relevant to sinter book film transistor on glass or fire-proof and explosion-proof viscoplasticity value linear character it is several
Also there is advantage very greatly in the difference change of individual important warm area.
And table 3 is the comparative example for being totally different from technical solution of the present invention, first its be entirely not boracic, not titaniferous,
Not iron content, the product without sodium composition, and wherein comparative example 1 and 2 be magnesium content also not 8.1-22.2% of the present invention it
It is interior, silicon: calcium or calcium: sample of the magnesium also above technical solution of the present invention scope.And comparative example 3,4,5,6 be representational liquid
Crystal display screen glass US2002/0011080A1 example, itself and all available liquid crystal boron glass patent documents and production
Product are the same, its Boron contents (1-11 samples of the present invention of table 1 be 0.01-3.9%) more than 5%, its not iron content (and table 1 it
The present invention foretells 11 sample iron content in 0.01-5%), not titaniferous (the 1-11 samples titaniferous of the present invention of table 1 is in 0.0001-4.9%),
It is all without sodium (the 1-11 samples of the present invention of table 1 contain sodium in 0.01-8.8%), and its silicon: calcium is all in 12 times to 60 times (this hair
Bright is 1.9-4.1 times), calcium：Magnesium all or 0.25 times or 1.75 times or unlimited times (present invention is at 1.2-1.6 times).And technology is imitated
On fruit, its six comparative examples melt viscosity temperature, clarification row bubble viscosity temperature, moulding process viscosity temperature be all higher by 150 DEG C-
More than 300 DEG C；Difference goes out 2-3 times and (is primarily due to either that aluminum oxide composition is very little or equally on the technique effect of rupture strength
During many aluminum oxide, because boron adds too much) in 5-15% scope a large amount of volatilizations of technologic boron can be caused to cause composition not
, material network short texture is produced, rupture strength is largely effected on, during the aluminum oxide 16-20% contents of such as comparative example 1, because containing
Its intensity for having 8.5% boron also only has 50-60MPa, and the example of the invention of table 1 can in about 20% alumina content
Up to 130-150MPa.
By more than description it is recognised that the present invention can realize glass smelting when each viscosity under temperature reduction,
So as to obtain preferable combination in glass properties and in terms of saving composition and power consumption two.However, the present invention is not limited to shown below
Example, but can be adjusted and changed as needed on the basis of the present invention.
On the basis of the above-mentioned first embodiment, restriction is counted as weight percents, is counted as weight percents, and aluminum oxide contains
Measure as 0.1-19%.

For a kind of various manufactures of above-mentioned formation plate glass according to embodiments of the present invention, one of them critically important side
Face is the brand new technical scheme of the composition with fluxing function of the present invention, substantially reduces the fusion temperature of glass, so that
This glass is also especially suitable for floating process, press over system technique.In conventional float process, press over system technique, this area one
Under the glass formula for being directly limited in high silicon components, need high intensity and in the case of needing to add aluminum oxide, it has to utilize
Various means even more extreme condition melts to raw material.At least in existing floating process, press over system technique, also
Glass formula according to embodiments of the present invention was not applied.Introduce in greater detail below, it is just according to embodiments of the present invention
A kind of applicable reason of plate glass formula to these three glass forming methods.
In the prior art, especially float glass process or press over system technique, it is adaptable to planarity requirements very high glass, are used especially in
The product of the 1.1mm-0.7mm or 0.5mm of display screen thickness, first ingredient requirement are high, it is impossible to have the calculus of non-fusible formation
Be cut point, so high is required to melt viscosity, otherwise defect is substantially, and product is unqualified；Followed by, homogenizing, row's bubble to product
Viscosity requirement is high, and not so bubble row is not thousand net, also in glass can be it is obvious that causing product unqualified；Especially to forming temperature
The requirement of viscosity is also high, because there is one to drop down flat, levelling technical process when float glass process is molded, if viscosity is high, Jiu Huitai
It is dense and drop down flatIt is graceful, influence yield, also can because levelling, drop down flat operation stage thickness difference is big and out-of-flatness, have influence on to form throwing
Light, the thickness difference of the product surface of the thin operation stage of drawing and irregularity degree are also big, and product surface has wave block defect, as present
PDP glass, will all pass through to float glass process product second polishing, exactly too big because of the viscosity that flat operation stage glass is dropped down in shaping
Cause.
So the present invention overcomes the technical scheme for first having conventional art prejudice, in floating process and press over system technique, calendering
Three main technique ranks of flat shaping are dropped down in method technique, lattice-method process, horizontal sheet process technique to fusing, homogenizing row bubble and levelling
The polishing of the viscosity of section and especially floating process draws the viscosity of thin technique to have significant Substantial technical progress effect.
In summary, glass of the invention especially can more embody the excellent of its technical scheme in various flat glass production process
More property, and overcome the technology prejudice in these fields.

The seventh embodiment of the present invention discloses a kind of plate glass of the invention on the basis of above-mentioned first embodiment,
On the plate glass, there is one layer of resin bed containing stone folder or aluminum oxide or mullite crystal.
A kind of plate glass of the present invention has the technical scheme of novelty to be in plate glass field：The glass bag is containing oxidation
Silicon, calcium oxide, magnesia, aluminum oxide, iron oxide, the composition of sodium oxide molybdena, are counted as weight percents, the boron oxide in the glass
Content is 0-3.9%, and the content of sodium oxide molybdena is 0.01-14%, and iron oxide content is 0.01-5%, and the content of fluorine oxide is 0-
2.81, content of magnesia is 8.1-22.2%, and alumina content is 0.01-39%, and the content of its silica is calcium oxide content
1.9 times -4.1 times, the content of calcium oxide is 1.2 times -1.6 times of the content of magnesia；The annealing temperature lower limit of the glass is (i.e.
Endothermic peak origin temp) it is 550 DEG C -710 DEG C；The thickness difference of the glass is less than 0.3mm；Scope of its water absorption rate in 0-0.3%
It is interior；Its rupture strength reaches 50-180MPa.
The feature of technical solution of the present invention has following level：
First, for the plate glass of all prior arts, be it is a kind of to aluminium, silicon, calcium, magnesium, iron, sodium compositional ranges
Selection invention and between silicon, calcium, magnesium composition, the type of the change invention of the proportionate relationship of these technology essential factors.In this hair
In the selection invention of the change of bright factor proportion relation, its technical scheme is silicon：Calcium is 2.0-4.1 times or 2.0-3.6 times,
Calcium：Magnesium is 1.2-1.6 times or 1.3-1.49 times of scope.And all plate glass of prior art, a minimum of above-mentioned two
Two end values of factor proportion relation, outside the scope of the invention, that is, the selection of above-mentioned factor proportion relation of the invention exists
Within the close limit of all prior arts, with novelty.And in plate glass purposes, it was found that new following product
Matter, generates following unexpected technique effects.
Second, the invention type for new application of being converted present invention is disclosed the new property of the product of discovery, is also to generate
The invention of unexpected effect (i.e. by various plate glass processing methods, in terms of new plate glass purposes, can be produced
It is raw：The plate glass new property such as thermal linear expansion coefficient feature, [1] different process stage outstanding new viscosity temperature and
Product, [2] thickness is poor, [3] water absorption rate, [4] rupture strength, [5] visible transmission ratio, [under 6] Bo Pattern degree, [7] annealing temperature
Limit (i.e. endothermic peak origin temp), the plate glass new property such as [8] thermal linear expansion coefficient feature, new application feature).
Especially in new application, present invention finds the product that prior art was never disclosed, melting process
Stage viscosity temperature, homogenizing, row bubble, clarification process stage viscosity temperature, especially control percent ripple flatness or thickness it is poor,
The viscosity temperature of thin (or polishing in the floating process) technique of drawing in moulding process stage.
(A), one of new discovery of property of product：Overcome the oxidation to flat board soda-lime glass of conventional art prejudice generation
The kind omitting elements invention of sodium technology：The sodium plate glass of prior art, it is mainly used to help all containing 13% or so sodium
Molten, especially to the fluxing of silicon composition, form each operation stage can control the reduction of viscosity.But technical scheme and
It was found that product new property, broken this technology prejudice, can due to the element relationship between silicon, calcium, magnesium change send out
Bright, in the purposes of plate glass, the product new property of generation, can be than prior art in sodium content when within 0-1%
The viscosity temperature of several operation stages of high sodium plate glass is low 150 DEG C -250 DEG C, and this will produce a large amount of energy-conservations and favourable son is high
Quality control product thickness is poor, percent ripple, and the bad generation of melting process plate glass calculus, quarrel point and row bubble technique it is bad
The defects such as the bubble rate of generation, particularly with having certain requirements such as the ultra-thin plate glass of 0.5-1.1mm LCD display
Quality, has reduction quarrel point, calculus rate, bubble rate, unqualified thickness rate, unqualified Bo Pattern degree rates, forms a scope big
Technical controlling platform much.
Prior art in operation, if once producing the defect of any one operation stage, is operationally all easy to adopt
Solved with the mode for the temperature for increasing each operation stage, but this just easily occurs making molten bath to collapse top very much, greatly shortens service life.
And the invention provides the viscosity adjustable extent of a technology manipulation for being advantageous to manipulate technique.Fundamentally solve in the industry
The technology of the product property (" material " said in the industry) of existing sodium (high sodium) plate glass " material property is short " that personage thinks always
Problem.
(B), the two of the discovery of the new property of product：Because the above-mentioned present invention accounts for plate glass total amount 99% to existing
13% sodium composition of calcium soda-lime glass be changed into a kind of 0.01-1% or 0.01-0.1% almost without sodium composition and omit hair
Bright new product property is the discovery that, the silicon of the present invention, calcium, the technical scheme of the factor proportion relationship change invention of magnesium, gram
Prior art has been taken only by that could produce the technology prejudice of annealing temperature rising because aluminium composition or boron composition are increased, has been generated
The product new property that annealing temperature lower limit also can be low 100 DEG C or so in low aluminium, low boron (only less than 1%), and contain in low sodium
When measuring (or less than 1%), annealing temperature can rise more product new properties (see sample example).Generate：The annealing of the glass
Lowest temperature (i.e. endothermic peak origin temp) is 610 DEG C -710 DEG C, and preferably 610 DEG C -650 ° (or are added alumina content, produced
Raw preferred 650 DEG C -710 DEG C product property, it is found that the annealing temperature lower limit of glass (absorbs heat because sodium composition is more
Peak origin temp) it is lower, the annealing temperature lower limit of more than 99% panel for construction glass of existing 13% sodium content (is inhaled
Thermal spike origin temp) there was only 490 DEG C, and the present invention without the annealing temperature of sodium (or only 0.01-1%) without boron plate glass
Lower limit (i.e. endothermic peak origin temp) is 610 DEG C -710 DEG C, because (same aluminium is 1% for the plate glass of technical solution of the present invention
Within when), because minimum magnesium is 8.1% (typically more than 12%), calcium is minimum 1.2 times, also 9.6% (generally
More than 15%), this be produce glass annealing temperature lower limit (i.e. endothermic peak origin temp) the main cause being substantially increased, than
Common existing calcium sodium plate glass is high 120 DEG C -200 DEG C, is a kind of discovery of other new product property.
Although it will be clear that increase calcium, magnesium content as reach 19-50% (containing only the common 10- of calcium+magnesium
12%) the calcium soda-lime glass more than prior art, it is convenient to omit boron composition can just make the annealing temperature lower limit of glass (absorb heat
Peak origin temp) rise significantly, and there is sodium oxide molybdena also to rise significantly up to 2-13%, simply than the product without sodium or low sodium
Annealing temperature lower limit (i.e. endothermic peak origin temp) rising is smaller, but is not to say that the composition for adding calcium and magnesium with regard to that can reach
The purpose of production, because also must simultaneously have the work of the viscosity temperature of suitable sub- plate glass especially relatively low exhaust bubble
Skill condition.The plate glass of prior art, if only increase the content of calcium and magnesium, rather than the silicon with the present invention, calcium, magnesium it
Between mutual proportionate relationship than all prior arts be exactly increase calcium-magnesium content its viscosity temperature still can be higher than the present invention 150
DEG C -300 DEG C, and such as alkali-free boron plate glass, it adds 8-15% fluxing agent boron composition, just only adds 8-10%
Aluminum oxide, viscosity be 102The temperature of row's bubble technique when (Pa Sec) is up to more than 1500 DEG C, it is necessary to use a kind of shallow pool
The high platinum row bubble passage of (depth of metal only 5-10cm) steeps process, and only several tons of daily output to complete exhaust.So
The low viscosity of itself and the present invention, have again high annealing temperature lower limit (i.e. endothermic peak origin temp) technical scheme can be with several
Hundred tons of daily output technique productions (row's bleb district pool depth reaches 70-100cm) compare, its quantum of output difference hundreds of times, and invest
More than tens times.Namely say, solving the rising of annealing temperature lower limit (i.e. endothermic peak origin temp), be allowed in accordance with various aobvious
Show device plate glass and colored glaze and the requirement of the plate glass such as fire-proof and explosion-proof, existing incision technology plate glass, or simply increase
Calcium+magnesium reaches 20-50% technical scheme, rather than takes change invention, the selection of the factor proportion relation of the present invention to invent
Technical scheme, is all that can not take into account the unexpected combination technique of cost and annealing temperature lower limit (i.e. endothermic peak origin temp)
Effect.
Its produce unexpected technique effect be not only in that can the inventive article without sodium or the low aluminium of boron annealing
Lowest temperature (i.e. endothermic peak origin temp) property and at 150 DEG C -300 DEG C and in 610 DEG C -650 DEG C or 680 DEG C of linear expansion
Coefficient value, can also have high-quality, low cost, high tens times of production efficiency etc. can be while reach production TFT liquid with taking into account completely
The technical requirements and the more preferable financial cost target of formation of crystal glass, and can also be used in the substrate of general PDP displays
In, reach that annealing temperature lower limit (i.e. endothermic peak origin temp) is higher than 580 DEG C of target, be allowed in 580 DEG C or so sintering process
Middle deformation is minimum, if moreover, add aluminum oxide, can also be higher, it can reach annealing temperature lower limit (the i.e. endothermic peak of liquid crystal standard
Origin temp) it is higher than 650 DEG C -710 DEG C of standard, glass substrate becomes when the sinter being allowed at 600 DEG C -650 DEG C stops pipe book film
Shape is minimum, is attained by within 3/1000000ths, is significantly better than existing PDP base plate glass and TFT alkali-free boron glasses.And use
In the LCD display of existing middle-end level, it can lift its hierarchy of skill, be conducive to upgrading and propose significantly that LCD is shown
(prior art LCD glass plates all use present annealing temperature lower limit, and (i.e. endothermic peak rises high-resolution pixel precision
Point temperature) be only 490 DEG C 13% sodium content plate glass；Another has the technical effect that, because viscosity temperature is less than existing
200 DEG C of soda-lime glass, can make LCD and PDP and TFT show glass to and have the thickness difference of high level and a product of ripple Pattern degree
The industry tip direction development of thinner 0.1-0.3mm premised on matter.
(C), the three of the discovery of the new property of product：The prejudice of conventional art is overcome, one to plate glass is generated
Plant a kind of omitting elements invention of " boron oxide " technology essential factor of alkali-free boron glass：The existing nothing particularly for liquid crystal display
Alkali boron plate glass, due to the sodium that can not contain more than 1%, (sodium oxide molybdena can progressively corrode the book film transistor being attached on glass for it
Very fine circuit), so all employing the boron composition of 8-15% contents to make fluxing agent composition, have and think the side of being far from it
Capable technology prejudice, is especially formed to the fluxing of silicon, with the viscosity temperature of each operation stage of the plate glass that can form high-quality
Reduction control.But technical scheme and find new property, broken this technology prejudice, can due to silicon, calcium,
The change invention of element relationship between magnesium, in plate glass purposes, produces new product property, in no boron oxide content
When as 0-1%, can than the product of the boron with 8-15% contents of prior art viscosity temperature, in the several of plate glass
Individual operation stage is low 250 DEG C -350 DEG C, and this will form an a wide range of control technique and reach the new of control product quality
Technology platform, for glass for liquid crystal display, the high-level thickness of this requirement is poor, ripple Pattern degree level and almost bubble-free,
Yield rate, the quality product rate of the ultrathin products of the 0.5-0.7mm thickness of quality requirements without quarrel point, without calculus defect are especially right
In exhaust bubble and clarification, homogenizing process stage and shaping, the viscosity for drawing thin operation stage, both provide one kind and compare prior art
Much better technology controlling and process scope and technology controlling and process platform.
(D), the four of the discovery of the new property of product：The one kind for overcoming classic flat-plate glass thinks that increasing aluminum oxide must
So produce the technology prejudice that viscosity temperature is substantially increased.Such as prior art calcium soda-lime glass, 1% or so aluminum oxide can only be added,
And existing alkali-free boron plate glass, this will have been made to improve strain point and add by also typically only adding 8% or so aluminum oxide
The viscosity temperature of very high each stage process is higher, it is impossible to the QT Quality Target for controlling technique to reach.Being also considered as can not be can
Under the controllable process conditions of low cost, aluminum oxide is added to 25-30%, to improve product strength.But the technology of the present invention
Scheme and the new flat glass product property found, have broken this technology prejudice, the present invention not boracic, without sodium, no
During fluorine-containing composition (during 0-1%), alumina content changes for the large span of 3.1% or 16% or 20% or 25% left ancient times
When, prior art thinks that viscosity can be substantially increased, but only 20 DEG C -40 DEG C of the change of the viscosity temperature of the present invention, is exactly aluminum oxide
For 1-30% or so big change when, viscosity temperature also only rise 40 DEG C -80 DEG C or so (see attached list 1 11 samples example and table 2
Sample comparative example).
And viscosity temperature than add also 100 DEG C of the flat glass product of 13% sodium oxide molybdena or 8-15% boron oxides-
200℃.This demonstrate that the inventive technique side of the factor proportion relationship change scope of silicon, calcium, magnesium in technical scheme
Case, can produce a kind of new product property in 25% or 30% content, here it is a kind of new high-alumina contains with aluminum oxide
Aluminium, silicon, magnesium, the congruent melting volume property of calcium of amount, can produce high aluminium content low viscosity temperature unexpected technique effect and
And then the unexpected technique effect of the high-quality high intensity produced.The present invention is especially because the content of aluminum oxide can be increased
During up to 19-28%, intensity can be much higher than various prior art plate glass intensity of about 140- 160MPa or 180MPa
2-3 times, and due to viscosity temperature also compared with prior art only 1-25% alumina contents when it is low 150 DEG C -250 DEG C, if so
During the viscosity of technical solution of the present invention formation alkali-free high boron glass, that, which should also have, arrives 29-39%'s equivalent to adding aluminum oxide
Larger space that the viscosity space that can be dissolved and intensity rise (rupture strength of this specification and glass of the embodiment of the present invention,
By sample being cut into 50mm × 50mm × 5mm small bar, using rupture strength instrument, surveyed by standard GB/T3810,4-2006
It is fixed.).The high boron product of alkali-free of prior art, because of the volatilization process of boron oxide composition, can cause the inequality of composition, make aluminum oxide
The material network structural damage of participation, largely effects on due intensity.This is that alkali-free high boron glass is exactly aluminum oxide containing 7-15%
The when also poor major reason of intensity.
So the present invention can be when having high aluminium content and without Boron contents, because that can have the silicon of high aluminium content, calcium, magnesium eutectic new
Property, while producing that up to 90-145MPa or 145-180MPa anti-folding Strong spends, and have concurrently it is more energy efficient, it is more inexpensive
It with the processing range for having bigger viscosity temperature, can be melted in melting process viscosity temperature stage control, overcome calculus and prevent
Produce the quarrel point that is not melted, when clarifying and controlling shaping plate glass thickness difference, Bo Pattern degree (it is lower because of viscosity, this
The flat glass product of operation stage is more soft more has the scope of control, otherwise viscosity is higher, this operation stage flat glass product
Harder, the operation stages such as the thin, polishing of flat, drawing that drop down for getting over not pull, horizontal drawing or calendering fortunately or float glass process control thickness difference and ripple
Pattern degree).
(E) iron oxide 0.01-4%, is added, is a kind of component invention, new function can be formed, high-quality resource is saved, greatly
Reduce cost greatly.
Third, due to the announcement and discovery of the property of new the said goods, above-mentioned a variety of prior art prejudice are overcome,
In various for building, TFT displays use, industrial, decoration is used, waterproof uses plate glass field, generates following expectation
Less than (1) of effect because viscosity temperature property is formd can lift and control well molten quality, the bubble product of technique
Poor and percent ripple quality the technique effect of matter, flatness, thickness；(2) it is unexpected due to viscosity temperature decline 200 DEG C
Energy-saving effect above；(3) it is unexpected because congruent melting volume property adds substantial amounts of aluminium (being added to more than 25% from 1%), production
Raw intensity rises 2-3 times of technique effect；(4) because intensity rises what thus producible plate glass can be frivolous 2-3 times
Save, economize on resources, saving logistics, the unexpected technique effect of 2-3 times of storage；(5) the new technique effect of the present invention is also
It is, can due to that can be used for being increased in the not high ornament materials plate glass of opaque or transparency on iron oxide content
To save the excellent shield frit resource increasingly reduced, major glass cost of material declines 10 times.Conventional art thinks iron-holder
Higher raw material influence glass produces the defect of blue green, but the present invention can lift intensity 2-3 in plate glass
Times, so can be thin 2-3 times, light transmittance skin and can rise, blue greenness is less obvious on the contrary, and the use of clear glass is not influenceed.
A kind of unexpected light, thin, high intensity can be produced, the high-end resource of glass is greatlyd save, saves former so this combination is the discovery that
Expect the flat glass product of the resultant effect of cost.This be other prior arts do not reach existing high intensity, it is not only light not only thin but also
Save the technique effect that raw material resources greatly save 10 times of cost of material again.(6) omitted as a result of a kind of technology essential factor
Invention, to prior art such as alkali-free boron glass, and can calculus more more preferable than prior art, quarrel point, bubble rate, flat
Degree, thickness difference quality control on the premise of, before technological temperature does not rise reduce and save on the premise of, province omit boron into
Part, can there are the fusing of plate process, row steep, are molded, drawing the better properties in thin each stage and more aluminum oxide can be added
And the rupture strength property produced, and unexpected 8-15% boron can be added without to flat-panel monitor alkali-free boron glass
Composition, and ensure that high-quality bubble rate, flatness, thickness be poor, percent ripple product quality guarantee, prior art can be solved
TFT display glass production device can only add the technology prejudice of the technique of platinum channel with press over system technique, and more highest is can
To use floating process, under the premise of poor thickness, flatness, the quality of percent ripple is ensured, production efficiency 20-40 can be improved
Times, can be 30-50 times with investment reduction, the unexpected effect of 20 times of Economization on land factory building.Technical solution of the present invention with it is existing
All plate glass Technical comparings, with it is new be not revealed with disclosed new property, and this property is prior nothing
Method speculates, it is impossible to predicts and infers what is come, and overcomeThe technology prejudice of traditional plate glass technology, solves people and exists
The above-mentioned significant problem solved is thirsted in industry, technique effect generates " matter " and " amount " change of the two, illustrates technical scheme
Right and wrong are creative with significant technological progress it will be apparent that with prominent substantive distinguishing features.
Above in association with specific embodiment to the composition and property and the manufacturing process of glass of glass of the present invention and application and
Technique effect is described, below to a kind of plate glass according to embodiments of the present invention the characteristics of, that is, its with it is existing
The fundamental difference of technology, then induction and conclusion are as follows：
The present invention is different from one of prior art：
Compared to the high content boron composition glass of more existing TFT liquid crystal displays alkali-free, there are hundreds of patents in the whole world and other
Document and thousands of embodiments, the alkali-free glass of its representational US2002/0011080A1 entitled liquid crystal display,
Wherein technical scheme is first consisted in maximum difference of the invention：(1) silica is 40-70%, calcium oxide in its technical scheme
For 0-15%, magnesia be 0-10%, boron oxide be 5-20% with silicon, calcium, the cross correlation of three technology essential factors of magnesium ratio
The selection invention of example relation, calcium of the present invention：The scope of magnesium is 1.2-1.6 times, and the upper range of prior art is calcium: magnesium is 0:
10 are less than 0.1 times, and lower limit is 15: 0, i.e., more than 15 times.So the value number that the present invention has been preferably within the scope of it, has
The difference of novelty, and its existing this kind of technology boron oxide content is 5-20%, not containing sodium oxide molybdena, not containing iron oxide, and
Technical solution of the present invention boron oxide content is 0-3.9%, and iron oxide content is 0.01-5%, and sodium oxide content is 0.01-
8.8%.Due to the difference of its technical scheme, the silicon of the present invention, calcium, the change invention of magnesium factor proportion relation are generated new
Product property, comparatively, in the feature of viscometric properties, all alkali-free boron glasses of this class, than the present invention without adding
Enter boron, be also added into the 10 of the product of 10-30% aluminum oxide0.5(Pa Sec), 101Viscosity temperature when (Pa Sec), 102
Clarification, homogenizing and row's bubble viscosity temperature when (Pa Sec), 103The viscosity temperature of the thin, polishing of shaping and drawing when (Pa Sec) etc.
Degree will be higher by 200 DEG C -400 DEG C.Obvious professional is both known about, and the low viscosity temperature of the present invention is advantageous in flat board
The melting process stage control quarrel point and calculus of glass, are easy to fully fusing, extremely have in exhaust bubble, clarification process stage
Beneficial to the control of bubble rate, (and the platinum that the existing alkali-free boron glass of all employs the sky high cost at a temperature of high temperature viscosity leads to
The exhaust bubble technique of duct device), the low viscosity of the present invention is more beneficial for molding plate glass certainly, is especially molded the super of TFT
Control flatness, the thickness of thin glass are poor, ripple township Wen Du quality level.(2) the alkali-free boron of all existing TFT LCDs
Glass is limited to the process production of press over system, due to the inevitable seriously corroded in molten bath, its whole palpus of hundreds of, whole world production line
Annual cold repair is once (about three months), costly every time to reach more than one hundred million RMB, and the present invention in composition can without boron, so
This great difficult problem can be overcome.(3) present invention can continuously 8-10 productions without cold repair, it is annual more than three months without the cold repair phase
Shuo produces production capacity.(4) due to there are 5-20% Boron contents in the composition of prior art, substantial amounts of boron is had in existing technology production
Volatilization, produces the uneven consequence of composition, and flatness quality during to shaping has harm, and the present invention is without boron composition, product
Flatness it is fine.(5) due to the equipment that press over system technique can only use 6-10 ton days now, and cost is up to 1,000,000,000 people
, can be in theory and existing to the heavy corrosion in molten bath more than people's coin, and because the use of its boron oxide composition of content at high proportion
In reality, it can not produced with the float glass process molten bath of large-tonnage, and technical scheme is due to can be without boron, so can
To be produced in the float glass process molten bath technique of 150 ton days or 200 ton days, it can rise 20-30 times, and cost of investment with yield
But only it is 1/the 40 or 1/60th of same production capacity, (line only hundred million yuans of 3-5) investment and depreciation can be greatlyd save
Cost, and save substantial amounts of reachable more than 10 times industrial land.(6) due to LCDs glass can be produced without boron composition
Glass, it is possible to be fully solved the boron toxic gas emission in the production of present boron glass (when Boron contents are 10% in such as product, in original
About 30% boron is added in material, about 20% boron poison gas volatilization can be given off in fusing, 10 ton days of such as prior art are overflow
Stream method technique, the boron poison gas discharge that have 2 tons daily, the boron toxic gas emission for having 20 tons if 200 ton day production capacities, and it is of the invention
The float glass line of 200 ton days of technical scheme can be without any boron toxic gas emission.(7) due to 5-20% boron composition (most liquid crystal
The boron of boron glass example is 8-15%) a large amount of volatilizations are had, cause composition uneven, so in same alumina content
During composition, the intensity of the liquid crystal display glass of all high boron can decline more than 80%, and the present invention can without boron or extremely low Boron contents,
So just having this high strength characteristics.Although and prior art its write in claim " ... calcium oxide is 0-15%, oxidation
Magnesium is 0-10%, and silica is 40-70% ", but the silica of its tens examples is all 60% or so, the calcium oxide overwhelming majority
In below 1-4%, only two 5.4%, one 6.2%, all not at 1.9 times -4.1 of silica: calcium oxide of the present invention
In the range of times, but in 10-60 times of scope, it is below 4-5% that its magnesia is also most, also in the oxidation of the present invention
Magnesium is outside 8.1-22.2% scope.By " individually contrasting principle " convention, the present inventor passes through to domestic and international hundreds of displays
The comparison of the patent claim of document and example in other words, is entirely so.So the present invention not only has a novelty, and from one
Cut for the claim of this kind of prior art, specification, example, all not disclosing technical scheme silicon, calcium, magnesium will
The change content of the invention of plain proportionate relationship and the new fluxing congruent melting constituent structure property and the outstanding viscosity of formation that produce, move back
Fiery lowest temperature (i.e. endothermic peak origin temp), intensity, energy-conservation, low cost, easily controllable product quality etc. technique effect.Especially
It is in viscosity, the technique effect of the relatively more existing low 300 DEG C of viscosity above temperature of all liquid crystal display glass；In the first-class 1- of intensity
2 times of technique effect, generates the unexpected technique effect of professional.The technique effect for illustrating the above of the invention is non-aobvious
And be clear to, it is creative.
Technique effect described in any one of the above, is not had in all existing liquid crystal display boron glass productions
Have what is disclosed or be disclosed, all right and wrong are it will be apparent that the technique effect of any one all reflects the technical scheme of the present invention
Creativeness.
The present invention is different from the two of existing glass technology：Prior art SU581097A1, discloses a kind of emulsion opal glass,
Its silica is 50-63%, and calcium oxide is 22-33%, and magnesia is 13-21%, and aluminum oxide is 1-3%, and sodium oxide molybdena is 0.5-
2%, calcium：Magnesium is 1.4-1.5.Its technical field and purposes with plate glass is entirely different, simply a kind of to produce milkiness effect
The technology of fruit glass, the main distinction of itself and the present invention is that the present invention is that a kind of have the complete of various plate glass techniques generations
Different characteristic as thickness difference ± 0.3mm, Bo Pattern degree in 20mm, waviness is within 0-0.03mm, rupture strength exists
50-180MPa, preferably in 0-180MPa or 145-180MPa, and the present invention contains iron oxide, and sodium oxide molybdena is 2.1-14%,
And control and specify that aluminum oxide is each under 0.01-30% or 3.8-30% or 19-30% or 26-39% different situations
The technical scheme of the technical matters index property such as viscosity temperature, intensity, annealing temperature of the operation stage of individual plate glass etc., and
And the present invention is the entirely different invention by purposes of plate glass, and the process taken be totally different from it is this
A kind of technique of plate glass of technology, such as floating process, horizontal drawing technique, lattice-method process, calendering technology, press over system technique etc. is simultaneously
Employ and newfound form high flat degree, high level thickness in product properties such as each plate glass operation stage viscosity temperatures
The product of difference and percent ripple and high breaking strength technique effect.And the goal of the invention of existing above-mentioned technology is a kind of chromatic colour of manufacture
Milkiness jealous glass device based article, it does not disclose new viscosity, intensity, flatness, the thickness of the product of the present invention completely
The unexpected technique effect for more not disclosing any present invention of the product properties such as poor, Bo Pattern degree.The present invention is patent hair
In the plate glass such as the building of a kind of high flat degree level in new entirely different purposes in bright type, industry, display
It was found that product new property and the invention type that generates unexpected technique effect, be also that one kind is never taken off this
The new property of the product shown is closed with existing plate glass technology Jin Hang Group, generates unexpected technique effect
Component invention.Such as：Due to one of new discovery of property of product overcome conventional art prejudice generation to flat board calcium sodium
A kind of omitting elements invention of the sodium oxide molybdena technology of glass：The sodium plate glass of prior art, its all containing 13% or so sodium,
It is mainly used to fluxing, especially to the fluxing of silicon composition, form each operation stage can control the reduction of viscosity.But the present invention's
The new property of technical scheme and the product found, has been broken this technology prejudice, can have been closed due to the key element between silicon, calcium, magnesium
The change invention of system, in the purposes of plate glass, the product new property of generation in sodium content when within 0-1%, can compare
The viscosity temperature of several operation stages of the high sodium plate glass of prior art is low 150 DEG C -250 DEG C, and this will produce a large amount of energy-conservations
Be conducive to high-quality to control the poor percent ripple of product thickness, and the plate glass calculus of the bad generation of melting process, quarrel point and arrange
The defects such as the bubble rate of the bad generation of technique are steeped, it is ultra-thin particularly with the LCD display having certain requirements such as 0.5-1.1mm
The quality of plate glass, reduction quarrel point, calculus rate, bubble rate, unqualified thickness rate, unqualified percent ripple rate.
Further, since the announcement and discovery of the property of new the said goods, overcome above-mentioned a variety of prior art prejudice,
In various for building, TFT displays use, industrial, decoration is used, waterproof uses plate glass field, generates following expectation
Less than (1) of effect because viscosity temperature property is formd can lift and control well molten quality, the bubble product of technique
Poor and percent ripple quality the technique effect of matter, flatness, thickness；(2) it is unexpected due to viscosity temperature decline 200 DEG C
Energy-saving effect above；(3) it is unexpected because congruent melting volume property adds substantial amounts of aluminium (being added to more than 25% from 1%), production
Raw intensity rises 2-3 times of technique effect；(4) because intensity rises what thus producible plate glass can be frivolous 2-3 times
Save, economize on resources, saving logistics, the unexpected technique effect of 2 times of storage.
The present invention is different from the seven of existing glass technology：The present invention provides a kind of photovoltaic solar device, and the photovoltaic is too

The application of new energy；Third, due to 1-2 times of glass thin can be made, it is possible to lift the handling capacity of solar energy, be conducive to carrying
Rise solar energy invention efficiency.
From the claim or example of above patent document or " individually contrast " principle of the judgement novelty of real product example
To judge that the technical scheme of the present invention also has novelty.
The present invention is different from energy-conservation, the ring that the brand-new technical scheme of above-mentioned various types of plate glass can simultaneously be produced
Guarantor, input-output ratio, production efficiency, cost declining and viscosity temperature is low, intensity is high feature etc., are all the unexpected of professional
Non-obvious technique effect；30-40% can be saved because dropping fusion temperature, carbon dioxide 30-40% is put in also emission reduction；
Also product strength can be made to rise 2-3 times, and the component invention of the display of new capability and photovoltaic solar device occur etc..
The present invention is summary of the inventor Jing Guo years'experiences and innovatively designs made, as foregoing
The technical scheme of the invention with any prior art, be all main to be changed by technology essential factor structure and its mutual proportionate relationship
Invention, and by opening up new application, find the difference of product feature of new product property and innovative approach formation (because appointing
The claim or example of what prior art all have from the technology essential factor feature of technical scheme at 3-5 or at 4-5 it is different
Part), so product of the present invention and process of preparing described in the claim refined out from this specification, are sentenced by novelty
Its " individually contrast " principle of breaking should have novelty.
Point out that it is pre- that technical scheme is produced in the characteristics of present invention just as the aforementioned is different from prior art part
Technique effect unexpectedly thirsts for solution, but the flat glass product and work having not been successful all the time always with solving people
Several significant technology issues of process, i.e. (1) are in the alkali-free boron glass production of especially TFT LCDs, Yi Jiben
The ratio of investment to output that the capacity efficiency that invention can be produced using floating process can rise 20-30 times can rise the problem of decades of times
Solution；(2) effect of energy-saving and emission-reduction in producing；(3) be conducive to it is thinning to the global same high intensity of half glass sheet, lighten for
To saving raw material 60%- 70% after 1/3rd, 60%-70%, emission reduction 60%-70% are saved；(4) without boron toxic gas emission
The solution of environmental issue and the solution of cold repair expense etc.；And the solution that (5) product strength is improved；(6) solution of flatness problem
Certainly；(7) to inland and the energy-conservation 60%-70% of transport by sea, carbon emission 60%-70 (8) building glass that can reduce transport is
Building lightweight application；(9) for glass sheet viscosity temperature controllability rising produce to product quality ensure
Control can bring lifting etc., in the contribution of these technology trends, suffer from important meaning.
So technical scheme is not the reasoning from logic for being a kind of use cylinder list thought or simple experiment afterwards
It can draw, the unexpected technological progress effect that especially this technical scheme is produced less is that professional is aobvious and easy
See.And these technical barriers are nearly ten to two ten years, global electronic display material industry and plate glass industry it is thousands of
Enterprise and hundreds thousand of technical staff of family, all it is researching and solving and the problem of never solve.Because the present invention is solved
The people of that states have technology trends of global plate glass and display industry and solar energy industry thirst for solving and another
What the significant technology issues and this specification directly having not been successful were mentioned also has many other people to thirst for solving and do not have
The ten foregoing multiple technologies problems succeeded.
Above-mentioned unexpected technique effect, is all because employing a kind of choosing for the proportionate relationship for changing technical scheme
Inventive technique scheme and a kind of change purposes are selected in plate glass, always not by prior art is disclosed or is disclosed new production
The viscosity temperature of each operation stage of moral character matter such as plate glass, also have high aluminium content when silicon, calcium, the technology of the present invention side of magnesium
Congruent melting body characteristicses of case etc. and the intensity produced and when overcoming low aluminium or low boron (within 1%) of plate glass, annealing temperature
The technology prejudice that can not rise and high annealing temperature lower limit (the i.e. endothermic peak origin temp) product property that produces and without boron
Low-viscosity, high strength characteristics under the conditions of composition, have broken prior art prejudice, and sodium or boron to prior art or
The technical solution of the present invention of the omission of the fluxing key element of the conventional art prejudice such as fluorine, and new technical scheme generate it is unexpected
Technique effect.The property of these technical products can not speculate in advance, unpredictable, inclined instant invention overcomes multiple technologies
See, generate in above-mentioned plate glass and display industry, New Energy Industry, what people thirsted for solving and never solved
The change of " matter " and " amount " of the unexpected effect of technical barrier solution, illustrate the present invention program right and wrong it will be apparent that
It is creative with prominent substantive distinguishing features and significant technological progress.
