  • This invention relates to aluminosilicate glass.
  • the present invention relates to aluminosilicate glass having high strength, high fracture toughness, and high scratch resistance. More specifically, the present invention relates to aluminosilicate glass which is used as a screen protection material for electronic products and which has high strength, high fracture toughness and high scratch resistance. Even more particularly, the present invention relates to aluminosilicate glass for high strength, high fracture toughness, high scratch resistance for touch screens. At the same time, the invention also relates to a chemical strengthening process for said aluminosilicate glass. Background technique
  • a touch screen is a display that can be sensed by touching and detecting within the display area, causing direct interaction with the display without the need for a keyboard, mouse or trackpad.
  • Touch screens such as resistive, capacitive, and projected capacitive touch screens require a glass substrate for depositing a transparent conductive oxide to conduct signals. In particular for the purpose of protecting the display, an additional cover glass is usually required.
  • the resistive touch screen conducts a touch signal through a surface flexible cover, which is typically a plastic or glass coated with a transparent conductive oxide film. Contact can cause the flexible cover to deform to the internal conductive substrate, thereby changing the resistance and current of the circuit, which is typically identified as a touch event for processing.
  • the surface flexible layer requires higher scratch resistance and transmittance, and plastics cannot meet this demand, so it is necessary to use
  • Capacitive touch screens typically sense a touch of a finger by a change in capacitance of the circuit, typically only a glass substrate with a double-sided TCO coating.
  • the glass as the substrate is plated with a transparent conductive oxide film (TCO), which is usually a soda lime glass coated with a TCO (transparent conductive coating).
  • TCO transparent conductive oxide film
  • Two sheets of glass plated with a TCO film form capacitors through spaced thin spaces.
  • the upper glass protects the display from damage and is therefore expected to have high surface scratch resistance and strength.
  • other types of touch screens such as surface acoustic wave type, optical induction type, and the like require a high transmittance, high strength glass panel or substrate.
  • Substrates and cover sheets in touch screen applications typically require strengthening and/or toughening of the glass to further increase the strength and toughness of the glass.
  • Glass surface enhancement technology includes not only the usual wind tempering (air jet enhancement) measures, but also chemical tempering techniques.
  • the essence of chemical tempering technology is to change the structure of the glass surface to enhance the strength of the glass surface.
  • Chemical tempering can also be called chemical strengthening.
  • Chemical tempering is generally divided into: 1) glass surface alkylation, 2) plating of a low expansion coefficient of vitreous material on the glass surface, and 3) alkali metal ion exchange. Chemical tempering as used herein refers to enhanced ion exchange.
  • the ion exchange enhancement mode is divided into two methods: high temperature ion exchange and low temperature ion exchange. Ion exchange enhancement can also be referred to as ion exchange enhancement.
  • High-temperature ion exchange enhancement refers to the formation of a metamorphic layer on the surface of the glass with a low thermal expansion coefficient of vitreous material above the glass strain temperature.
  • Typical high temperature ion exchange is to heat the glass containing Na 2 O and K 2 O above the strain temperature, immersing it in a molten salt containing Li+ below the softening temperature, and heating the glass and molten salt above the strain temperature.
  • the glass network is slack, the surface is easy to change, and the ion exchange between Na+ or K+ and Li+ between the glass and the molten salt is promoted. After a period of time, the surface of the glass is ion exchanged with Na+ or K+, and the glass is annealed.
  • a layer rich in Li+ ions is formed on the surface of the glass. Since the expansion coefficient of the Li+ layer is much lower than that of the Na+ or K+ containing ion layer (the sodium-rich, potassium-rich glass and the lithium-rich glass have different coefficients of thermal expansion), the glass surface and internal shrinkage are different during cooling, so A residual compressive stress layer is formed on the surface of the glass to generate a tensile stress layer inside the glass. If the glass also contains ⁇ 1 2 ⁇ 3 and Ti0 2 , a TiO 2 — ⁇ 1 2 ⁇ 3 — 4SiO 4 crystal having a smaller thermal expansion coefficient will be formed during ion exchange, and a very large compressive stress will be generated after cooling.
  • Low-temperature ion exchange enhancement Low-temperature ion exchange is common. The principle is that the glass is immersed in the alkali metal compound molten salt with an ionic radius larger than the alkali metal ions contained in the glass at a temperature lower than the glass strain temperature. Large ions squeeze into the glass mesh. In the space originally occupied by small-sized ions, small-sized ions are displaced into the molten salt.

  • the amount of such basic ions should be as high as possible to provide sufficient exchange sites without losing other characteristics.
  • ⁇ 1 2 ⁇ 3 is also an essential component to provide a high strength glass frit, and it is important to form a larger network that can serve as a diffusion channel to hold alkali metal ions, which will result in rapid and efficient ion exchange.
