Abstract

The invention relates to the technical field of display glass, especially to antifouling anti-dazzle display glass and a preparation method thereof. The display glass contains a transparent glass substrate and an antifouling anti-dazzle film which is formed after an antifouling AG solution is sprayed onto the surface of the transparent glass substrate and solidified. The surface of the antifoulinganti-dazzle film has an uneven microstructure. The antifouling AG solution contains 3-8% of nano-TiO2 / SiO2, 80-86% of ethanol and 6-12% of petroleum ether. The nano-TiO2 / SiO2 is a core-shell hollow structured spherical nanoparticle with TiO2 as the core and porous SiO2 as the shell, and there is a 2nm-3nm nano-space layer between the core and the shell. The preparation method comprises steps as follows: preparation of nano-TiO2 / SiO2, preparation of the antifouling AG solution, and spraying and solidification for film formation. According to the preparation method, the antifouling AG solutionis sprayed onto the transparent glass substrate and solidified to form the antifouling anti-dazzle film which is not easy to fall off, and then the antifouling anti-dazzle display glass which is durable in use and has excellent wear resistance is prepared.

Description

technical field [0001] The invention relates to the technical field of display glass, in particular to an antifouling and antiglare display glass and a preparation method thereof. Background technique [0002] The display screens (especially touch screens) of portable electronic devices such as mobile phones, digital cameras, personal digital assistants (PDAs), tablet computers, and notebook computers are designed to prevent scratches or damage due to excessive finger force. Damaged, the surface of the screen is usually covered with a piece of tempered glass for protection. However, the smooth surface of strengthened glass is easy to accumulate dirt, which affects the display effect. It needs to be wiped frequently, and it is also disturbed by the environment and external light. Specifically, it will cause glare and reflected light due to the light shining on the smooth surface. So as to affect the visual quality. [0003] Glare refers to the visual condition that causes v...
