Embodiment 1

[0051] Convert and weigh the corresponding raw materials according to the mass percentage of the following components: SiO 2 58%, Al 2 o 3 12.5%, Na 2 O 9%, K 2 O 9%, MgO 8%, ZrO 2 0.41%, ZnO 3%, Co 3 o 4 0.015%, CeO 2 0.015%, La 2 o3 0.015%, SeO 2 0.015%, Nd 2 o 3 0.015%, Fe 2 o 3 0.015%;

[0052] Mix the weighed glass raw materials evenly to form a glass mixture, pour the above glass mixture into a crucible, place the crucible containing the glass mixture in a high-temperature furnace for melting, set the melting temperature to 1450°C, and melt the glass mixture Finally, the molten glass was obtained, and the above molten glass was incubated and homogenized at 1450°C for 4 hours. In order to make the glass components uniform, a platinum rod was used to stir the molten glass during the heat preservation period. The bubbles in the molten glass escaped and each part of the molten glass was stirred by stirring. The components are evenly distributed. The ab...

Abstract

The invention discloses a glass for chemical strengthening, a chemically strengthened glass, a production method of the glass for chemical strengthening, a production method of the chemically strengthened glass, a production glass for display devices, and a display device in order to solve the problems of yellow green color of glass and warping of processed glass. The glass comprises 58-68% of SiO2, 4.5-15% of Al2O3, 8-16% of Na2O, 4-12% of K2O, 5-12% of MgO, 0.01-2% of ZrO2, 0.1-4% of ZnO, 0.005-1% of Fe2O3, 0-1% of a ninth component and 0.005-0.2% of a tenth component; the ninth component is at least one of CaO, SrO and BaO, and the tenth component is at least three of Co3O4, CeO2, La2O3, SeO2 and Nd2O3. The glass for chemical strengthening has no yellow green color, has a good chemical strengthening effect, and has no warping phenomenon after chemical strengthening treatment.

Description

technical field [0001] The invention relates to the technical field of glass production, in particular to a chemically strengthened glass, a chemically strengthened glass and a preparation method thereof, a protective glass for a display device, and a display device. Background technique [0002] With the development of science and technology, the application scope of touch screen has become more and more extensive, from the operating system of factory equipment for industrial use, electronic inquiry facilities for public information inquiry, cash machine for commercial use, to mobile phones of consumer electronics, Touch screens can be found in PDAs, digital cameras, and more. [0003] Display products with touch screen and handwriting functions often prefer glass materials as protective glass (also known as protective cover, cover glass, cover glass or cover plate, etc.). The above-mentioned protective glass is used as the outermost protective member of the touch screen. P...
