Problems solved by technology

(2) Break down integrated circuits and precision electronic components, or promote component aging, reducing production yield
Second, the harm caused by electrostatic attraction (ESA): In order to ensure the surface quality of the glass and avoid the adhesion of the glass in direct contact when the substrate glass is packaged, the glass is separated by a spacer paper. When grabbing the spacer paper at the application end, if If there is static electricity, electrostatic adsorption will occur, and the basic glass will be brought up when the spacer paper is grabbed, which will damage the substrate glass

Embodiment 1-6

[0060] Weigh each component according to the glass composition shown in Table 1, mix well, pour the batch into a platinum crucible, then heat in a high-temperature furnace at 1600°C for 5 hours, and stir with a platinum rod to remove air bubbles. The melted glass is poured into a stainless steel mold to form a specified block glass product, and then the glass product is annealed in the annealing process for 1 hour, and then the power is turned off and the furnace is cooled to room temperature. The glass product is cut, ground and polished, then cleaned with high-purity water and dried to obtain a finished glass product with a thickness of 0.6mm. Various properties of each glass product were measured respectively, and the results are shown in Table 1.

Abstract

The invention relates to the field of glass manufacturing, and discloses an aluminosilicate glass composition, aluminosilicate glass and a preparation method and application thereof. Based on the total weight of the aluminosilicate glass composition, the aluminosilicate glass composition contains 55-73wt% SiO 2 , 7‑28wt% Al 2 o 3 , 0‑8wt% of B 2 o 3 , 0.05‑4wt% TiO 2 , 2‑20wt% alkaline earth metal oxide RO, 0‑1wt% Gd 2 o 3 , 0‑2wt% La 2 o 3 and unavoidable impurities. The glass prepared by the invention has the characteristics of high thermal stability, high strain point, high UV 308nm transmittance, low thermal expansion coefficient and low static electricity, and is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the field of glass manufacturing, in particular to an aluminosilicate glass composition, aluminosilicate glass and a preparation method and application thereof. Background technique [0002] With the rapid development of display technology, especially the application of flexible display technology, various display terminals have gradually developed towards higher resolution, brighter and low power consumption. Under this trend, higher requirements are put forward for display panels. , the performance of the glass substrate, which is an indispensable material for the display panel, also puts forward higher requirements. Low temperature polysilicon material (LTPS) has higher electron mobility than traditional amorphous silicon material (a-Si), so compared with traditional amorphous silicon thin film transistor liquid crystal display (a-Si TFT-LCD), low temperature polysilicon TFT-LCD has the advantages of higher resolution, fast...
