Abstract

The invention belongs to the technical field of chemical printing ink, and specifically relates to an aqueous toughened glass printing ink dedicated for touch screen and a preparation method thereof. The aqueous toughened glass printing ink is prepared from the following raw materials in parts by weight: 6 to 28 parts of inorganic pigment, 20 to 50 parts of first glass powder frit, 10 to 40 parts of second glass powder frit, 10 to 60 parts of aqueous varnish, 0 to 2 parts of wetting dispersant, 0 to 1 part of antifoaming agent, and 0 to 2 parts of leveling agent. The printing ink can improve the surface acoustic wave signal transduction performance of touch screen glass, solves the problem that after surface acoustic waves go through tough screen glass, the signal attenuates, and has the advantages that the covering performance of the printing ink is good, the surface acoustic wave propagation speed is quick, the energy attenuation is little, no phase change happens, and the corrosion of the printing ink is weak.

Description

technical field [0001] The invention belongs to the technical field of chemical inks, and in particular relates to a special water-based tempered glass ink for touch screens and a preparation method thereof. Background technique [0002] Touch screen, also known as touch screen, is a new computer input device, and is currently the simplest, most convenient and fastest way of human-computer interaction. It is widely used in military electrical appliances, aerospace electrical appliances, high-speed rail, aircraft carrier ships, ships and automobiles, Industry 4.0 Internet of Things, financial banks, commercial retail, industrial control, interactive digital signage and game entertainment. Current touch screens mainly include surface acoustic wave, infrared, resistive, capacitive and other types. The surface acoustic wave touch screen has the characteristics of high resolution, good stability, and good light transmission, which makes it win in other types of touch screen appl...
