Problems solved by technology

The main material of existing high-temperature resistant inks is mostly silicone-modified epoxy resin with high and low temperature resistance, weather aging resistance, and high dielectric strength; It is easy to turn yellow during high-temperature treatment, which has a serious impact on the display effect of the OGS touch panel; and the functional additives are selected for the main material, considering the overall stability, viscosity, hardness, etc., and cannot make the ink resistant to temperature and resistance. Yellow side has better effect and function

Abstract

The invention provides high-temperature-resistant ink. The high-temperature-resistant ink comprises the following components: 100 parts of organosilicone-modified resin, 60-240 parts of titanium dioxide powder, 0.5-10 parts of fumed silica, 1-30 parts of crosslinking agent, 0.01-1 part of silanol condensation catalyst, 0.1-4 parts of polysiloxane defoaming agent, 0.1-4 parts of alkyl and / or aralkyl-modified polyorganosiloxane leveling agent and 50-150 parts of solvent. According to the high-temperature-resistant ink disclosed by the invention, since organosilicone-modified resin is adopted as a main component and functional additives such as the specific crosslinking agent, the silanol condensation catalyst, the defoaming agent and the leveling agent, are mixed to jointly improve the performances, such as high temperature resistance, resistance to yellowing, stability and the like of an ink product and thus a white glass ink product with excellent high temperature resistance and chemical resistance is obtained.

Description

technical field [0001] The invention belongs to the technical field of printing ink for touch panels, and in particular relates to a high-temperature-resistant ink, a preparation method thereof, and an OGS touch panel. Background technique [0002] In the existing OGS (One Glass Solution, all-in-one touch) touch panel manufacturing process, it is first necessary to print high-temperature resistant ink on the ITO substrate to control the hardness and chemical resistance of the surface, so as to effectively protect the conductive material in the subsequent process. Silver paste, ITO coating, printing photoresist, exposure, development, etching ITO film, stripping photoresist, etc. are protected; then the adhesion, hardness and stripping time can be controlled, which can greatly improve the yield. In the above-mentioned process, the high-temperature-resistant ink itself will be printed first, and it will undergo subsequent high-temperature environment, developer, ITO etchant an...
