Embodiment Construction

[0010] A coating material for a platinum channel, the key is: the weight percentage of each component in the formulation components of the coating material includes: glass component 40-60%, silicon dioxide 30-55%, zirconia 5- 20%.

[0011] The weight percent of each component in the formulation components of the coating material is preferably: glass component 45-50%, zirconium oxide 8-15%, silicon dioxide 45-50%.

[0012] The silicon dioxide is colloidal silicon dioxide or a mixture composed of colloidal silicon dioxide and silicon dioxide particles, and the percentage by weight of the colloidal silicon dioxide in the total amount of silicon dioxide in the mixture is 20-40%.

[0013] The weight percentage of colloidal silicon dioxide in the silicon dioxide mixture to the total amount of silicon dioxide is preferably 30-35%.

[0014] The glass composition is borosilicate glass, aluminosilicate glass or aluminoborosilicate glass.

[0015] The weight percentages of each compone...

Abstract

A coating material for platinum channels, which solves the technical problem of platinum loss and glass quality affected by the long-term high temperature of glass manufacturing devices for existing platinum components. The technical solution adopted is that the formula of the coating material consists of The weight percentage of each component in the composition comprises: glass component 40-60%, silicon dioxide 30-55%, zirconia 5-20%. 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. The beneficial effect of the invention is that: during the test, the test result data show that the coating material covers the platinum sheet without loss of platinum, and has an excellent protective effect.

Description

technical field [0001] The invention relates to a coating material for a platinum channel, which can be used to reduce the loss of the platinum channel at high temperature in the production process of an electronic glass substrate, in particular to a coating material for the platinum channel. 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 overflow pull-down method,...
