Abstract

The invention discloses a high-strength protective glass plate for electronic display equipment to solve the problem that an existing display screen has higher requirements on thinning and strength of high-aluminum glass plates. The high-strength protective glass plate consists of the following components in percentage by mass: 59-64% of SiO2, 13-17% of Al2O3, 11-15% of Na2O, 0.1-6.5% of K2O, 5.1-7% of MgO, 0-0.7% of CaO, 0-0.2% of SrO and 0-1.2% of ZrO2. The lowest thickness of a prepared glass plate can reach 4mm, and the prepared glass plate has relatively high surface hardness and strength, so that the quality of the glass plate is further improved, the service life of the glass plate is prolonged, and the aim of protecting electronic components including display screens and the like is achieved.

Description

technical field [0001] The invention relates to a glass plate, in particular to a high-strength protective glass plate for electronic display equipment. Background technique [0002] With the rapid development of the human-machine touch industry represented by mobile phones and tablets, high-alumina glass plates have replaced traditional soda-lime glass plates and become protective glass plates for mobile phones, tablets and other products. However, with people's pursuit of lightweight mobile phones, tablets, etc., that is, larger and thinner display screens, in daily use, display devices will fall and collide due to improper use and negligence, which will lead to protection. Breakage of glass. Therefore, this puts forward higher requirements for the thinning and strength of the high-alumina glass plate. [0003] Technically, glass with a thickness of 0.1 to 1.1 mm is generally called ultra-thin glass. According to the production process, there are float ultra-thin glass, ...
