Abstract

The invention relates to the technical field of touch screen glass substrates, and discloses a high-strength touch screen glass substrate and a preparation method thereof. The touch screen glass substrate is prepared from the following components in parts by weight on the basis of oxides: 70 to 80 parts of SiO2, 14 to 18 parts of Al2O3, 13 to 16 parts of Na2O, 2 to 3 parts of K2O, 2.7 to 3.5 parts of CaO, 3.8 to 4.6 parts of MgO, 0.1 to 0.3 part of SnO2 and 0.05 to 0.1 part of ZrO2. By adopting the formula, the mechanical strength of the touch screen glass substrate can be effectively improved, and meanwhile, the bubble defect in the touch screen glass substrate is reduced.

Description

technical field [0001] The invention relates to the technical field of touch screen glass substrates, in particular to a high-strength touch screen glass substrate and a preparation method thereof. Background technique [0002] As an advanced electronic input device, the touch screen has many advantages such as simplicity, convenience, quick response, space saving and easy man-machine communication. With the rapid development of modern technology, it has become the first choice of many electronic display products. Touch screens mainly include five types: resistive, surface capacitive, projected capacitive, surface acoustic wave, and infrared. Among them, projected capacitive touch screens are currently the most widely used type of touch screens. They are small in size and relatively low in cost. It is suitable for consumer electronics and mobile devices, and contains one or more layers of indium tin oxide (ITO), which can recognize two-finger touch without requiring users to...
