Embodiment 1-6

[0042] Weigh each component as shown in Table 1, mix well, pour the mixture into a platinum-rhodium crucible, keep it in a high-temperature furnace at 1550°C for 10 hours, and stir with a platinum rod to remove air bubbles. Pour the molten glass into a stainless steel cast iron mold to form a specified block glass product, then anneal the glass product in an annealing furnace at 650°C for 2 hours, turn off the power and cool down to 25°C with the furnace. The glass products are cut, ground and polished, and the polished glass products are put into the molten KNO at 420°C 3 Treat in different times, then take it out and cool it down to 25°C, wash it with deionized water and dry it to make a finished glass product. Various properties of each glass product were measured respectively, and the results are shown in Table 1.

[0049]

[0050] Comparing the data of Example 1 with Examples 5-6 shows that, based on the weight of the composition, the composition contains 62-73wt% SiO 2 , 9-18wt% Al 2 o 3 , 11-20wt% Na 2 O, 2-5 wt% K 2 O, 0.5-0.9 wt% ZrO 2 and 0.3-0.5wt% CeO 2 , using the composition for glass to prepare glass can further improve hardness, chemical strengthening effect and impact resistance.

[0051] Comparing the data of Example 1 with Examples 7-9, it can be seen that the use of SiO 2 、Al 2 o 3 、Na 2 O, K 2 O, ZrO 2 and CeO 2 The glass composition for preparing glass can significantly improve hardness, chemical strengthening effect, impact resistance and light transmittance.

Abstract

The invention relates to the field of glasses, and discloses a glass composition, an impact-resistant glass and a preparation method and an application thereof. The glass composition comprises the following components by weight: 55-80wt% of SiO2 (silicon dioxide), 6-20wt% of Al2O3 (aluminium oxide), 10-25wt% of Na2O (sodium monoxide), 0-6wt% of K2O (potassium oxide), 0.1-1wt% of ZrO2 (zirconium dioxide), and 0-0.5wt% of CeO2 (cerium dioxide). The glass prepared by the glass composition has excellent impact-resistant property, and is suitable for protection cover plates of display device screens.

Description

technical field [0001] The invention relates to the field of glass, in particular to a composition for glass, impact-resistant glass and a preparation method and application thereof. Background technique [0002] Cover glass is the main upstream raw material for manufacturing touch screens. The application fields of touch screen products range from notebook computers, mobile phone GPS (global satellite navigation system), POS (point of sale terminal) to various flat panel display industries, and the market is broad. Traditional soda-lime-silicate glass changes the composition of the glass surface through chemical tempering, which can increase the strength of the glass, but it is difficult to meet high hardness, scratch resistance, impact resistance and other properties. Contents of the invention [0003] The object of the present invention is to provide a composition for glass, impact-resistant glass and its preparation method and application in order to overcome the above...
