Description
Technical field
The present invention relates to technical field of glass materials, and in particular to it is a kind of with low cost high-voltage stress under compression layer without alkaline earth
The phosphorus alumina silicate glass of metal oxide.
Background technique
After aluminum silicate glass passes through chemical intensification treatment, make surface layer of glass that there is high bearing stress (Compressive
Stress, abbreviation CS) and formed certain depth ion exchange layer (Depth of Layer, abbreviation DOL), realize quickly improve
Glass surface hardness, shock resistance, scratch resistant performance and traumatic resistance energy, so that being widely used in touch-control shows product most
Outer layer cover board protection materials.
The scratch depth that general glass surface generates is generally at 30 μm~50 μm, therefore it is required that glass surface ion exchange layer
Depth, which reaches 60 μm, may conform to requirement of the major applications scene to scratch resistance and high strength cap glass sheet.Chemical strengthening at present
Treatment process generallys use a step ion-exchange and two step ion-exchanges.One step ion-exchange mainly introduces in glass
The sodium oxide molybdena of high-content forms, to provide enough Na+K in ion concentration and fused salt+It swaps, to be produced in glass surface
Raw surface compression stressor layers.The DOL value for having been commercialized glass after glass intermediate ion exchanges at present is respectively less than 50 μm, and main cause is
Commercialization glass is limited by ion-exchange speed, and glass need to can be only achieved 50 μm of (quotient by least 10 hours ion exchanges
Industry glass through making annealing treatment again again), the high strengthening time is substantially reduced production efficiency, increase it is glass reinforced it is temporal at
This.
Chemical intensification treatment technique is from a step ion-exchange (Na in glass at present+K in ion and fused salt+Exchange)
Gradually to two-step solution method (Li in progress glass first+Na in ion and fused salt+Exchange, then carry out Na in glass+Ion
With K in fused salt+Exchange) development, main purpose is to promote the depth DOL value of ion exchange layer, to effectively promote glass
Damage tolerant performance.After being exchanged by double ion, the ion exchange layer depth of glass reaches 80 μm or higher, but the ion exchange
80% or more depth of layer depth mostlys come from Li in glass+Na in ion and fused salt+Exchange is formed, and Na in glass+Ion and
K in fused salt+Exchange exchange layer depth is at 15 μm hereinafter, so as to cause the reduction of glass surface scratch resistance capability.It has engaged in trade at present
It is both needed in the glass of double two-step solutions of industry containing lithia ingredient, and the raw materials such as lithium carbonate that lithia uses introduce
And cause cost of material very high, so that glass itself is on the high side, it is difficult to universal；Furthermore ion is being carried out containing lithium glass
In strengthening process, lithium ion is very big to the side effect of ion exchange fused salt, accelerates the service life for shortening the salt containing sodium fusion, thus
The production cost of cover board processor is improved, therefore although higher ion exchange layer may be implemented in two-step solution glass,
But it needs client to undertake high cost price, while also limiting the popularization and application of two step ion strengthened glass.Do not have still at present
There is a product that there is the glass product of low cost and high compression stress layer.
In addition, glass is required to be processed into as the touching display screen of the surface modelings such as 2.5D, 3D gradually becomes main product
Product with 2.5D, 3D surface modeling.After glass is processed to 2.5D from 2D and makes 3D moulding using hot bending processing procedure,
It needs to inevitably remain many visible or invisible scratch in glass surface, also to wrap glass surface polishing processing
It is dirty containing polishing powder etc..It is dirty effectively to remove glass surface, frequently with acidic cleaner in ultrasonic wave and about 55 DEG C~65 DEG C
Glass is cleaned in environment, the oxalic acid solution that cleaning solution is about 2 for example, by using PH.Glass is in acid aqueous environment
Under, the Na of glass surface+With H in water+Exchange interaction occurs for ion, so that generating one layer in glass surface has protection glass table
The hydroxide film layer in face, but under acidic environment, hydroxide film layer is by H in weakly acidic condition+It neutralizes, so that glass be accelerated to hand over
The effect of changing, so as to cause glass, weight loss becomes even more serious in weak acid environment, especially when glass surface remain due to
The damage that processing procedure generates, in pickling environment is cleaned, microscopic damage gradually becomes macroscopic damage for such damage, from
And glass surface is caused to generate apparent visual defects, such as visible scuffing, atomization, white point etc., to reduce the transmission of glass
Rate influences production yield.In water or acidic aqueous solution, SiO in glass2Ingredient glass surface formed one layer have water resistant and
The protective film layer of capacity antacid, the presence of the protective film layer make Na in glass+With H in water+Exchange rate, which occurs, for ion reduces, with
It causes to stop, so that effective protection glass surface, makes it that can be subjected to acid processing procedure.

Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of phosphorus aluminum silicate glass with low cost and high compression stress layer.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of phosphorus alumina silicate glass with low cost and high compression stress layer, includes following components with molar percent
Are as follows: SiO2 65~75%；Al2O38~16%；Na2O 11~16%；K2O 0~5%；P2O5 1~4%；B2O3 0~4%；ZnO0~
1%；SnO2 0~1%；
It also include (CaO+MgO+SrO+BaO)≤0.1mol% in the component of the glass；
In the component of the glass, more preferable (CaO+MgO+SrO+BaO+ZnO)≤0.1mol%；
It also include 2mol%≤P in the component of the glass2O5+ K2O≤6mol%；
The glass the coefficient of mean linear thermal expansion < 90 × 10-7/℃。
Surface compression stress value 500MPa~1000MPa of the glass compaction layer.
The glass impregnates weight per unit area loss late≤0.15mg/cm after 6hrs in 60 DEG C of oxalic acid solutions2。
The reasons why carrying out numerical definiteness to the content of each ingredient below is illustrated:
SiO2: SiO2For main glass shaping body, belong to one of essential component, the main composition netted main structure of glass assigns
The preferable chemical stability of glass, mechanical performance and processability.SiO in glass2Ingredient, which forms one layer in glass surface, to be had
The protective film layer of water-fast and acid-fast ability, SiO in glass2Content is higher, and protective film layer is water-fast to glass and acid resistance is stronger,
SiO2At least 65mol%, preferably 66mol% or more, more preferable 67mol% or more；Improve SiO in glass2It is raw that content reduces glass
Cost is produced, because of SiO2The quartz sand cost of material in source is minimum, but excessively high SiO2Content improves glass melting temperature, from
And glass is caused the defect of a large amount of minute bubbles occur；It is excessively high to may also lead to crystallization, therefore SiO2It is at most 75mol%, more preferably
Ground is at most 73mol %.
Al2O3: Al2O3For one of the essential component of glass, belong to network intermediate composition.In high-alkalinity glass ingredient
In, alkali ion is to Al3+Ion carries out charge balance, so that most aluminium oxide is tended to glass aluminum-oxygen tetrahedron, constitutes
The netted main structure of glass, to improve stability, glass and mechanical performance.Al2O3The aluminum-oxygen tetrahedron formed in glass is in glass
Volume ratio oxygen-octahedron volume is big in glass, and glass volume expands, and is glass in ion to reduce the density of glass
Exchange process provides interchange channel, improves glass compaction stress layer depth, Al in glass2O3Content is at least 8mol%, it is preferable that extremely
It is less 10mol %, more preferably at least 12mol%；But Al2O3Belong to pole refractory oxides, can quickly improve high temperature viscosity of glass,
Cause glass clarifying and homogenization temperature sharply to increase, causes the air blister defect concentration in glass to increase significantly, especially in glass
With high concentration SiO2In the case of, high concentration Al2O3Cause glass to be difficult to clarify, causes yields reduction that production cost is caused to increase
Add；In addition, when containing high concentration Al in glass2O3Afterwards, glass structure is more loose, is alkali metal ion (such as Na in glass+
Deng) and weak acid in H+Ion generation ion exchange offer is more possible, to reduce glass surface acid resistance ability.Therefore exist
Al in glass2O3Content is at most 16mol%, it is preferable that is at most 14mol %.
Na2O:Na2O is one of the essential component of glass, the Na of glass middle and high concentration2O, so that containing enough in glass
Na+, with K in potassium nitrate fused salt+Ion swaps, to generate high compression stress in glass surface.In addition, Na2O can be mentioned
For a large amount of free oxygen sources, destruction is risen to glass silica network structural body, the viscosity of glass is reduced, facilitates glass melting
With clarification, therefore, Na in the present invention2O content is not less than 11mol%, it is preferable that is not less than 12mol%, it is highly preferred that being not less than
13mol%.But Na2O excessive concentration, will be so that glass machinery performance and chemical stability deteriorate, especially in high-alumina concentration
In the silicate glasses of phosphorus containing components, Na2O is easier to be inclined to and exchanges and dissolved in water with the hydrogen ion in water, reduces glass
Water-fast and acid resistance.Therefore Na in glass2O content is at most 18mol%, it is preferable that is at most 16mol%.
Li2O: glass ingredient at most includes 0.1% Li2O belongs to functionality.Certain Li in glass2O concentration helps
In the melt viscosity for reducing glass, so as to improve fusing effect, a small amount of Li2O helps to improve the water resistance of glass, but high
Li2O tends to hinder Na+And K+Exchange, and glass raw material cost can greatly increase, therefore Li is preferably free of in the present invention2O。
K2O: K in glass2O belongs to functionality, K2O can improve glass melting and clarifying effect；K in glass2O and
Na2" mixed alkali effect " is generated in the presence of O is common, so as to improve water-fast and acid resistance in glass；When maintenance is certain in glass
K2O concentration helps to obtain the compressive stress layers for improving glass, K2The bearing stress that O concentration generates glass ion exchange drops
It is low to become apparent；But high K in glass2The deterioration of O concentration chemical stability, makes glass acid resistance be deteriorated；K2The potassium carbonate in the source O and
Saleratus cost is increased with respect to sodium carbonate.Therefore, K in glass of the invention2O content is preferably 0~5mol%, more excellent
It is selected as 1mol%~3mol%.
B2O3: B in glass2O3At Network former oxide is belonged to, high temp glass viscosity can obviously reduce；High concentration
B2O3There are oxide volatilization phenomenon during high temperature melting, it is unfavorable for glass ingredient and stablizes, and high B2O3Concentration reduces glass
Viscosity, so as to cause the reduction of strain point of glass temperature.In addition, the experiment of ion exchange shows high B2O3Oncentration on Ionic exchange
Inhibition is played, the acquisition of glass high stress layer depth is unfavorable for；And B2O3Cost of material is relatively high, therefore B2O3Content≤
3mol %, more preferably≤2mol%.
P2O5: P in glass2O5Belong to glass former ingredient, with [PO4] tetrahedron is mutually interconnected into network, but P2O5Shape
At network structure belong to stratiform, and interlayer is connected with each other by Van der Waals force, makes glass network structure in rarefaction, and network is empty
Gap becomes larger, and is conducive to Na in glass+K in ion and fused salt+Ion carries out phase counterdiffusion, to glass reinforced technical process intermediate ion
Exchange plays a driving role, to be quickly obtained higher compression stressor layers serve it is extremely important.High P2O5Concentration stablizes glass chemistry
Property be deteriorated, while P2O5Raw material sources the cost is relatively high.Therefore P2O5Content preferably 1~4 mol%.
Divalent metal oxidation includes CaO, MgO, SrO and BaO etc., is glass network ectosome ingredient, to glass network knot
Structure plays destruction, reduces glass melting temperature.But oxides, divalent metal, which plays the velocity of ion exchange of glass, to be hindered to make
With, it is difficult to the glass with high compression stress layer is obtained, therefore, (CaO+MgO+SrO+BaO)≤0.1mol% in the present invention.
ZnO: ZnO belongs to bivalent metal oxide in glass, is glass network ectosome ingredient, rises to glass network structure
Destruction reduces glass melting temperature, is good fluxing agent, is conducive to clarify.In high basic metal oxide silicate glass
In glass, Zn2+There are hexa-coordinate [ZnO6] and four-coordination [ZnO4] state, wherein hexa-coordinate [ZnO6] structure is comparatively dense, and four match
Position [ZnO4] structure is more loose, four-coordination quantity increases with alkali metal oxide and is increased.As four-coordination [ZnO4] content is more
When, glass network is more loose, is conducive to glass intermediate ion (Na+) migrate, to improve glass ion exchange layer depth, compare
CaO, MgO and SrO of the same clan is to the inhibition of ion exchange, and ZnO content is to raising glass ion exchange efficiency positive effect.
In addition, the surface compression stress that ZnO can maintain strengthened glass surface high, is easy that surface compression stress value is made to be more than 1000MPa；This
Outside, the raw material sources of ZnO are at high cost, and production cost can be reduced by reducing ZnO content in glass, are conducive to product and obtain bigger model
The application enclosed.Therefore ZnO content≤1mol%, more preferably≤0.1mol%.
In addition to above-mentioned oxide, contain chemical fining agent in glass of the invention.Wherein SnO2It is clear for main high temperature
Clear agent, and it is environment-protecting and non-poisonous, but the SnO of high concentration2It is easy to generate excess of oxygen, causes excessive gas bubbles left in glass, and SnO2It is former
Expect higher cost, content is at most 0.4mol %, more preferable 0.2mol%.
Phosphorus alumina silicate glass of the invention has high surface compression stressor layers, and one side can be by reducing by two in glass
Valence metal ion oxide concentration limits (CaO+MgO+SrO+BaO)≤0.1mol% in glass ingredient, can greatly reduce glass
To Na in bivalent metal ion component+Ion and K+The resistance of ion exchange；On the other hand, by optimization glass in the present invention
