Problems solved by technology

The chemically strengthened glass used as the cover glass of the display device can effectively protect the display device from being damaged, but if it is damaged by a large external force during use, it cannot better protect the display device from damage
The mechanical properties and chemical strengthening effect of the chemically strengthened glass used in the traditional cover glass need to be improved, especially in terms of scratch resistance, wear resistance and bending resistance, so as to better protect the screen of the display device and extend the electronic life. product lifespan

Embodiment 1

[0037] Convert and weigh the corresponding raw materials according to the mass percentage of the following components: SiO 2 60%, Al 2 o 3 11%, Na 2 O 15%, K 2 O5.5%, ZnO 4%, La 2 o 3 1.5%, Fe 2 o 3 1%, SnO 2%;

[0038] 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 above-mentioned molten glass is poured into a preheated stainless steel cast iron mold and so...

Embodiment 2

[0040] Convert and weigh the corresponding raw materials according to the mass percentage of the following components: SiO 2 57%, Al 2 o 3 16%, Na 2 O 11%, K 2 O7.7%, ZnO 3%, La 2 o 3 2%, Fe 2 o 3 0.8%, SnO 2.5%;

[0041] In Example 2, the raw materials were prepared according to the above formula, and the test sample of Example 2, namely No. 2 glass, was prepared by the method of Example 1; wherein, the melting temperature was 1500° C., and the homogenization time was 6 hours.

Embodiment 3

[0043] Convert and weigh the corresponding raw materials according to the mass percentage of the following components: SiO 2 58%, Al 2 o 3 14%, Na 2 O 14%, K 2 O7%, ZnO 3.5%, La 2 o 3 1%, Fe 2 o 3 0.5%, SnO 2%;

[0044]In Example 3, the raw materials were prepared according to the above formula, and the test sample of Example 3, namely No. 3 glass, was prepared by the method of Example 1; wherein, the melting temperature was 1550° C., and the heat preservation and homogenization time was 8 hours.

Abstract

The invention discloses a glass, a chemically strengthened glass, a production method of the glass, a production method of the chemically strengthened glass, a display device cover glass and a display device in order to solve the problem of unsatisfactory mechanical performances of glass. The glass comprises, by mass, 56-65% of SiO2, 5-16% of Al2O3, 10-15% of Na2O, 2-8% of K2O, 1-5% of ZnO, 0.01-3% of La2O3, 0.01-1% of Fe2O3, and 0.5-3% of SnO. The glass has the characteristics of high refractive index, high bending strength, high elastic modulus and good chemical strengthening effect.

Description

technical field [0001] The invention relates to the technical field of glass production, in particular to a glass, a chemically strengthened glass, a preparation method thereof, a cover 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 cover glass (also known as protective cover, protective glass, cover glass or cover plate, etc.), and the above-mentioned cover glass is used as the outermost protective member of the touch screen. The requirements are high, and it...
