Abstract
The invention relates to a coating material for a platinum channel, and aims to solve the technical problems of platinum loss and influence on glass quality since a glass manufacturing device for a conventional platinum component is at a high temperature for a long time. According to an adopted technical scheme, a formula of the coating material comprises the following components in percentage by weight: 30-50 percent of glass components, 10-40 parts of silicon dioxide, 5-30 percent of magnesium oxide and 20-40 percent of zirconium oxide. The coating components in the coating material are selected on the basis of an inertial molten film shielding type protection mechanism of the protection action of a coating system on a substrate, and the bonding action of a molten composite phase is combined with the substrate at a high temperature, so that a dispersion process is prevented or retarded, the erosion of the substrate by a corrosion medium is reduced, and the aim of protecting the substrate is fulfilled.
Description
technical field [0001] The invention relates to a coating material for platinum channels, which can be used to reduce the loss of platinum channels at high temperatures in the production process of electronic glass substrates, in particular to a coating material added with high temperature resistant components. technical background [0002] In the past ten years, flat panel display technology has developed rapidly, gradually replacing traditional CRT display products. Among many new flat panel display technologies, TFT-LCD has become the mainstream color flat panel display technology. TFT-LCD is gradually recognized by consumers due to its advantages of large effective display size, high definition, light weight, and good environmental performance. Terminal display devices, as well as TVs, laptops, desktop monitors, etc. [0003] TFT-LCD liquid crystal display substrates are generally aluminum-containing borosilicate glass, and the production methods mainly include overflo...
