Description

It is a kind of with high strain-point, can fast ion exchange and weak acid resistant zinc phosphorus aluminium silicon Silicate glass
Technical field
The present invention relates to technical field of glass materials, and in particular to one kind have high strain-point, can fast ion exchange and The zinc phosphorus alumina silicate glass of weak acid resistant.
Background technique
With the development and demand of touch screen and monitor market, touch screen and display cover glass sheet is driven to send out rapidly Exhibition and demand.With pursuit of the people to the mobile terminal apparatus such as smart phone appearance and performance, cover-plate glass is from traditional 2D shape, gradually to 2.5D, 3D profile transitions.This also proposes the cover-plate glass performance as protection screen more harsh Requirement.But common silicate glass intensity is not still able to satisfy routine use demand, as mobile phone repeatedly fall and With the collision of sharp objects etc., the breakage of screen can be all caused.It is required that cover-plate glass need to have high Resisting fractre, it is counter-bending with And good drop resistant fall performance, the cover-plate glass of 1mm is less than for thickness, generally requiring to handle by chemical tempering makes glass have surface Ion exchange layer (Depth of Layer, the abbreviation of compression (Compressive Stress, abbreviation CS) and certain depth DOL), while CS and DOL glass with higher effectively can inhibit glass surface defects to extend, to improve glass surface Hardness, scratch resistance and good drop resistant fall performance.
When glass carries out ion exchange, the ion-exchange effect of glass depends on the temperature and time of ion exchange, temperature Degree is higher, and the speed of ion exchange is faster, and compressive stress layer is deeper, but surface compression stress value is smaller, mainly ion exchange mistake Cheng Zhong, there are stress relaxation phenomenons for glass.The stress relaxation of glass can generally be mitigated by reducing the temperature of ion exchange, thus Higher surface compression stress value is maintained, but the efficiency of ion exchange reduces simultaneously, causes compressive stress layers too low, therefore, very It is difficult to reach high surface compression stress value and high compression stress layer simultaneously.
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.When glass is processed to 2.5D and 3D from 2D, need to make glass surface Type processing processes 2.5D glass for example, by using CNC processing procedure and processes 3D glass using hot bending shape processing procedure, and glass surface can not What is avoided is damaged in procedure for processing, and glass surface residual is many dirty, such as the polishing powders such as cerium oxide.To remove glass Glass surface it is dirty, generally glass is cleaned using weak acid pickling agent, for example, by using the oxalic acid solution of PH ≈ 2, therefore, It is required that glass surface has certain weak acid resistant performance, glass surface is avoided not destroyed by weak acid and generate visible scuffing, to drop The transmitance of low glass influences yield.Especially when introducing a certain amount of P in glass2O5After component, the chemical stability of glass drops It is low, to make the weak acid resistant reduced performance of glass；The report that can solve the above problem was not met at present.
Summary of the invention
The purpose of the present invention is to provide it is a kind of with high strain-point, can fast ion exchange and weak acid resistant zinc phosphorus aluminium Silicate glass, the glass have high surface compression stress, high compression stress layer and weak acid resistant simultaneously.
To achieve the above object, the present invention adopts the following technical scheme:
It is a kind of with high strain-point, can fast ion exchange and weak acid resistant zinc phosphorus alumina silicate glass, based on mass fraction, The group that the glass includes is divided into SiO2 56~65 %, Al2O317~22%, Na2O 10~16 %, K2O 0~1%, Li2O 0 ~1%, P2O5 0~5%, B2O3 0~2%, MgO 0~0.5%, ZnO 1 ~ 8%, TiO2 0~1%, SrO 0~0.5%, SnO2 0 ~0.5%, CeO2 0~0.5%, the sum of each component is 100%.
In the component of the glass, SiO2+Al2O3+P2O3>=78%, (MgO+ZnO+SrO+Al2O3)/( Li2O+Na2O+
K2O+B2O3) >=1.3, strain point temperature >=580 DEG C of glass, compression stress value >=900MPa, compressive stress layers >=35 μ m。
Preferably, in the component of the glass, SiO2+Al2O3+P2O3>=80%, (Al2O3+P2O5)/ZnO > 3, (MgO+ ZnO+SrO+Al2O3)/( Li2O+Na2O+K2O+B2O3) >=1.5, strain point temperature >=600 DEG C of glass, compressive stress layers >= 40μm。
In the component of the glass, (Li2O+Na2O+K2O + Al2O3)/SiO2< 0.60, glass have weak acid resistant, and Weight per unit area loss late≤0.15mg/cm after immersion 6hrs in 60 DEG C of oxalic acid solutions3。
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 glass2At belong to acidic materials erosion it is main Component, and its strain point temperature that can improve glass, therefore SiO2Content is at least 56 %, it is preferable that it is at least 59 %, it is more excellent Selection of land, at least 60 %；But high SiO2Content can be such that glass melting temperature improves, and a large amount of minute bubbles occur so as to cause glass Defect, while surface compression stress and compressive stress layers after glass ion exchange can be also reduced, therefore SiO2Content is at most 65%, it is preferable that be at most 64 %, it is highly preferred that being at most 63 %.
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, while high Al2O3Concentration glass has high strain-point temperature, So that glass maintenance is higher after glass ion exchange is compressed into stress, Al in glass2O3Content is at least 17 %, preferably Ground, at least 18 %；But Al2O3Belong to pole refractory oxides, can quickly improve high temperature viscosity of glass, causes glass clarifying equal Change difficulty to increase, the air blister defect concentration in glass increases significantly, therefore Al in glass2O3Content is at most 22 %, preferably Ground is at most 21 %.
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+, swapped with K+ ion in potassium nitrate fused salt, thus glass surface generate high compression stress.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 substantially reduced, facilitates glass Fusing and clarification, therefore, Na in the present invention2O content is not less than 10 %, it is preferable that is not less than 11%, it is highly preferred that being not less than 12%.But Na2O excessive concentration, will so that glass machinery performance and chemical stability deterioration, especially in high-alumina concentration and 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, accelerates glass surface Chemical property variation, therefore Na in glass2O content is at most 16 %, it is preferable that is at most 16 %.
Li2O: glass ingredient at most includes 1 %Li2O belongs to functionality.Certain Li in glass2O concentration facilitates The melt viscosity of glass is reduced, so as to improve effect, but high Li is melted2O tends to hinder Na+And K+Exchange, it is preferable that glass In be free of Li2O。
K2O: K in glass2O belongs to functionality, K2O can improve glass melting and clarifying effect；When being maintained in glass Higher K2O concentration helps to obtain high compression stress layer, but this compressive stress layers are not necessarily potassium ion and sodium ion in fused salt Ion exchange occurs and is formed；High K simultaneously2O concentration becomes apparent the bearing stress reduction that glass ion exchange generates；This Outside, high K in glass2The deterioration of O concentration chemical stability, makes glass acid-resisting be deteriorated.Therefore, K in glass of the invention2O content is extremely Mostly 1%, preferably 0, mainly introduced by raw material impurity.
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 B2O3Glass strain can be reduced Point temperature, and it tends on the glass surface, glass surface resistance can deteriorate.The experiment of ion exchange shows high B2O3 Concentration is unfavorable for glass and obtains high compression stress and high stress layer depth, therefore B2O3Content is less than 2 %, preferably 0.
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 in glass that K ion carries out phase counterdiffusion, glass reinforced technical process intermediate ion exchange in Na ion and fused salt It plays a driving role, plays an important role to higher compression stressor layers are quickly obtained.But P in glass2O5It is small with viscosity, chemical stabilization Property difference and the big effect of thermal expansion coefficient, therefore low concentration P2O5Glass can be provided with preferable chemical stability, the P of high concentration2O5 Deteriorate the acid-resisting of glass surface.Therefore P2O5Content is at most 5%, preferably 1~4 %.
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, exchange depth There is positive effect with glass surface intensity is improved, but the ZnO of excessive concentrations tends to form gahnite (ZnAl2O4) or silicon Sour zinc (Zn2SiO4), to improve the devitrification temperature of glass.Therefore ZnO content control is in 1~8 %.It is preferably 2~6 %.
MgO: MgO belongs to bivalent metal oxide in glass, is glass network ectosome ingredient, rises to glass network structure Destruction reduces glass melting temperature, is conducive to clarify.But high MgO concentration acts on strength of glass raising limited；And In terms of the Antacid effectiveness of glass, MgO effect ratio ZnO effect is poor, and therefore, content of MgO is at most 1%.
SrO: SrO belongs to bivalent metal oxide in glass, is glass network ectosome ingredient, rises to glass network structure Destruction reduces glass melting temperature, is conducive to clarify.But high SrO concentration improves glass density, and cost of material is expensive. Therefore SrO content is at most 0.5 %.
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, content It is at most 0.5 %.Wherein CeO2To aoxidize clarifying agent, it can also be decolorising agent, improve glass transmitance, but excessive concentration, easily lead Glass coloration is caused, to reduce transmitance, therefore, content is at most 0.5 %.
Zinc phosphorus alumina silicate glass glass of the invention has high surface compression stress, is the strain point by improving glass Temperature reduces what the stress relaxation phenomenon in ion exchange process obtained.All rise to glass network result destroys work in glass Oxide, such as Na2O、K2O and Li2O, it is most obvious to the effect for reducing strain point of glass temperature；And it is advantageous in glass In the component for forming network structure, such as Al2O3、SiO2And P2O5It works most obviously to strain temperature is improved, therefore the present invention Middle glass has the SiO of high concentration2、Al2O3And P2O5Content, SiO2+Al2O3+P2O5>=76wt% simultaneously limits (MgO+ZnO+SrO+ Al2O3)/( Li2O+Na2O
+K2O+B2O3)≥1.3.Preferably, SiO2+Al2O3+P2O5≥80wt%；Preferably, (MgO+ZnO+SrO
+Al2O3)/( Li2O+Na2O+K2O+B2O3)≥1.5；So as to improve the ion-exchanging efficiency of glass, shorten glass reinforced Time improves the surface compression stress value and compressive stress layers of glass.
Glass in the present invention has the ability of good weak acid resistant, and the present invention improves the weak acid resistant of glass by three aspects On the one hand performance improves SiO in glass2Content is formed, it is particularly evident which improves glass weak acid resistant effect in pairs, it is desirable that glass Middle SiO2Concentration is not less than 56wt%；On the one hand to Li in glass2O、Na2O、K2O and Al2O3Lead to the weak acid resistant energy of glass surface Power reduces ingredient and is limited, and restrictive condition is (Li2O+Na2O+K2O + Al2O3)/SiO2< 0.60；On the other hand, it introduces high ZnO concentration reduces MgO concentration to improve the ability of glass weak acid resistant.
Remarkable advantage of the invention is: one aspect of the present invention improves the strain point temperature of glass by reasonable composition proportion Degree and the ion-exchanging efficiency for improving glass, obtaining has high surface compression stress value and compressive stress layers strengthened glass；It is another Aspect, the present invention improve SiO in glass2Content is formed, and to Li in glass2O、Na2O、K2O and Al2O3Lead to glass surface Weak acid resistant ability reduces ingredient and carries out limitation and introduce ZnO concentration in high alumina glass ingredient, reduces MgO concentration, so as to improve Improve the ability of glass weak acid resistant.
