Description
Technical field
This disclosure relates to strengthened glass technical field, in particular it relates to a kind of glass composition and preparation method thereof and should
With.
Background technology
Glass is always material indispensable during Display Technique develops, with the development of Display Technique, by chemical strong
The intensity of glass can be improved by changing the composition of change glass surface, and glass is more applied in the protection of display device.At present
Tablet personal computer, LCD TV, mobile phone, digital camera etc. are all equipped with touch-screen, and in use, touch-screen cover plate glass
Glass is prone to contact and rubbed, and adds casual delineation, touches, it is thick that resulting cut directly contributes touch screen surface
Rough, finish declines, and influences using effect, is more likely to result in screen rupture.
According to the demand in market, direction of the touch-screen cover-plate glass just gradually towards more high-quality is developed.The main body of its high-quality
Present surface stress is big, suitable, heat-resisting stress layer depth, heat shock resistance, it is frivolous it is suitable it is in large size in terms of.At present, carrying
Progress in terms of high toughness, reduction fragility is still barely satisfactory, does not there is breakthrough, the damage of touch-screen cover-plate glass
It is bad also to be caused more by damage-resistant energy deficiency.
Therefore good mechanical property after a kind of glass composition, reinforcing is needed badly, collapse resistance is anti-drop, can be prepared as high property
The touch-screen cover-plate glass of energy.
