preparation example Construction

[0023] The preparation method of the coating material in the present invention: the present invention can directly mix zirconia particles, magnesia particles and glass components, silicon dioxide particles and colloidal silica, and make slurry for coating, or pre-coat the zirconia Granules, magnesia particles, glass components, and silica particles are mixed, and then the sintered body obtained by pulverizing and sintering is used as a coating material mixed with the pulverized pulverized product and colloidal silica. The slurry of the coating material preferably contains water-soluble macromolecules such as methyl cellulose as an organic binder, and the content of the organic binder accounts for 0.5-10% by weight of the inorganic solid component in the slurry, more preferably in 0.5% by weight. 1-5% by weight.

[0024] The coating method of the coating material of the present invention: coating on the platinum material in the form of slurry, coating the slurry on the platinum...

Abstract

A coating material for a platinum channel, which solves the technical problem of platinum loss and glass quality being affected by the long-term high temperature of the glass manufacturing device of the existing platinum component. The technical solution adopted is that the key lies in: the coating material The percentage by weight of each component in the formula components includes: 30-50% of glass components, 10-40% of silicon dioxide, 5-30% of magnesium oxide, and 20-40% of zirconium oxide. The choice of coating components in the present invention is based on the protective effect of the coating system on the substrate as an inert melt film shielding protection mechanism. At high temperatures, the bonding effect of the molten composite phase is combined with the substrate to prevent or slow down the diffusion process and reduce the corrosive medium. Erosion of the substrate to achieve the purpose of protecting the substrate.

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...
