Embodiment Construction

[0011] A touch screen cover glass with strong acid and alkali resistance, the components in the glass components are calculated by weight percentage as follows:

[0012] SiO 2 55-67%,

[0013] Al 2 o 3 16-24%,

[0014] Na 2 O 13-18%,

[0015] ZnO 0.1-4%,

[0016] TiO 2 0.1-1%.

[0017] The SiO 2 The content is preferably 60-63%.

[0018] The Al 2 o 3 The content is preferably 18-22%.

[0019] The Na 2 The O content is preferably 14-17%.

[0020] The ZnO content is preferably 0.5-3.5%.

[0021] The TiO 2 The content is preferably 0.5-0.8%.

[0022] SiO 2 It is a component that constitutes the glass skeleton, SiO 2 Higher content, chemical resistance and mechanical strength will increase, high temperature viscosity of glass will increase, SiO 2 If it is too much, it will be difficult to obtain glass with long material properties. SiO 2 Low content is not easy to form glass, the strain point decreases, the expansion coefficient increases, th...

Abstract

The invention provides a touch screen cover plate glass high in acid and alkali resistance and aims at solving the technical problems of poor acid and alkali resistance of the existing touch screen cover plate glass in the chemical enhancement process. The adopted technical scheme is as follows: the glass is composed of the following components in percentage by weight: 55-67% of SiO2, 16-24% of Al2O3, 13-18% of Na2O, 0.1-4% of ZnO and 0.1-1% of TiO2. The touch screen cover plate glass has excellent acid and alkali resistance, and is suitable for chemical enhancement treatment; the enhanced glass is high in surface hardness.

Description

technical field [0001] The invention belongs to the technical field of glass production, and relates to a glass material for screen protection of display products, in particular to a touch screen cover glass with high acid and alkali resistance and excellent mechanical properties after chemical strengthening. Background technique [0002] In order to effectively reduce the cost of the touch module and meet the market trend of thinner and lighter terminal consumer electronics products, the touch industry has been actively developing OGS touch screen technology since 2011. OGS technology is to integrate the touch screen with the protective glass. A technology that directly forms ITO conductive film and sensor. A single piece of glass does double duty as both the protective glass and the touch sensor. From a technical point of view, OGS technology has the following advantages over the mainstream G / G touch technology: simple structure, light, thin, and good light transmission, ...
