Description
Technical field
The present invention relates to intelligent glass field more particularly to a kind of intelligent light-controlled glass high rigidity substrate and its preparation sides
Method.
Background technology
Intelligent light-controlled glass is that one layer of liquid crystal film is clipped between layer glass, liquid crystal film be covered in by PVB films it is most central, so
It is placed on autoclave or general one-step method stove back warp is crossed the process gluing of high temperature and pressure and formed.Intelligent light-controlled glass is in addition to tool
Standby privacy protection function, is provided simultaneously with the application characteristic of all safety glasses.Due to intelligent light-controlled glass construction complexity, cost compared with
Height is not easy to grind colored damage, reduces transport and service wear therefore it is required that the hardness of glass substrate is higher, reduces cost, and conventional
Float glass or ultra-clear glasses this requirement is all not achieved.
Invention content
In order to solve the above technical problem, the present invention provides a kind of intelligent light-controlled glass high rigidity substrate and its preparations
Method.By adjusting the component of glass substrate, with when preparation process, obtained being suitable for the high rigidity that intelligent light-controlled glass uses
High grade of transparency substrate.
The specific technical solution of the present invention is：The substrate contains following components and parts by weight：80-120 parts of silica, oxygen
Change 10-15 parts of sodium, 7-9 parts of calcium oxide, 15-20 parts of aluminium oxide, 3-5 parts of magnesia, 2-4 parts of zinc oxide, yttria 1.5-
2.5 parts, 2.8-3.2 parts of zirconium dioxide, 2.5-3.5 parts of antimony oxide, 1-3 parts of phosphorus pentoxide, 3-5 parts of titanium dioxide.
SiO2It is important glass former oxide, with oxygen-octahedron [SiO4] structural unit formed it is irregular
Contiguous network becomes the skeleton of glass.Its content affects the endurance and mechanical strength of glass, in addition also to the density of glass
Also it will produce influence.Content is higher, and the chemical resistance and mechanical strength of glass are higher.On the other hand, due to having raising viscosity
Tendency, content is too high, increases the high temperature viscosity of glass, and glass is made to be difficult to melt.
Al2O3It is the neccessary composition for improving chemical durability of glass.
MgO、ZnO、Na2O and CaO is the network modifying oxide of glass, can reduce the viscosity of glass, promotes glass
Fusing and clarification, improve forming of glass performance, and a certain amount of network modifying oxide can improve the hardness of glass, chemistry
Stability, thermal stability and mechanical strength.But Na2O can reduce thermal stability, chemical stability and the mechanical strength of glass.CaO
When higher, the tendency of glass can be made to increase, and easily make glass embrittlement.When the content of MgO and ZnO is higher, it can go out in glass
Existing other crystal, can reduce the transparency of glass in this way.Therefore when the network modifying oxide introduction volume of glass is less, Ke Yiyu
Other oxide collective effects improve the mechanical performance of glass, but when the amount replaced is excessive, and the mechanical performance of glass can be significantly
Reduction.
Yttria has stronger accumulation to act on, and can promote the densification of glass structure, in addition, yttria can
To play the role of stabilizer, zirconium dioxide is stablized in tetragonal phase, nucleating effect is improved；Phosphorus pentoxide can increase dioxy
Change the solubility of zirconium in the melt, while the melt temperature of zirconium dioxide can be reduced；And zirconium dioxide is as Nucleating Agent, it can be with
Nucleation and crystallization activation energy are reduced, nucleation rate is accelerated, promotes glass coring and crystallization, the four directions oxidation that yttria is stablized
Zirconium effect is more excellent, and can organize excessively growing up for nucleus, reduces out-phase crystallization.Three can reduce into as Composite Nucleation Agents
Nuclear barrier promotes nucleation and crystallization, improves the crystallization property of glass, can preferably obtain the glass of crystalline phase single stable, pole
Big limits its out-phase crystallization in crystallization process, while can reduce the defects of glass, improve glass hardness and
Mechanical performance can meet intelligent light-controlled glass to substrate high rigidity, wear-resisting requirement.
Titanium dioxide can reduce crystallization temperature, promote crystallization.
Alkaline earth oxide has " mixed alkali effect ", refers under conditions of the total content of alkaline earth oxide is constant,
Another or two kinds, performance change curve not instead of straight line is replaced to change a kind of alkaline earth oxide,
There is extreme value in specific position, therefore the additive amount of alkaline earth oxide is difficult to find rule.
