Abstract

The invention discloses a sealing glass added with nanometer aluminum oxide and the preparation method of the sealing glass. The sealing glass is characterized in that the mol percentages of raw material components are as below: 35 percent to 50 percent of P2O5, 20 percent to 45 percent of ZnO, 0.1 percent to 20 percent of B2O3, 1 percent to 10 percent of Al2O3, 0.1 percent to 10 percent of SiO2, 0.1 percent to 10 percent of Na2O, 0.1 percent to 10 percent of MgO, 0.1 percent to 5 percent of Li2O, 0.1 percent to 4 percent of Fe2O3, and 0.1 percent to 4 percent of MnO2; the preparation method is as below: mixing the raw materials, wherein the nanometer aluminum oxide is the last to be added and then mixed to prepare a mixture; placing crucible in an electric cooker with a temperature of 1,200 to 1,400 DEG C, and the preheating for 15 minutes; adding the mixture into quartz crucible, performing smelting at the temperature of 1,200 to 1,400 DEG C, and allowing the temperature to be kept for 80 to 120 minutes; pouring the smelted glass liquid into water or tabletting the glass liquid and then grilling the tablets into powder, or casting the glass liquid into sticks, poles, tablets, and other shapes needed during the sealing; performing test and package. The invention has the advantages of simple preparation process, convenient operation and high cost performance and has wide market development prospect.

Description

【Technical field】 [0001] The invention relates to the technical field of electronic glass, in particular to a sealing glass added with nano-alumina and a preparation method thereof. 【Background technique】 [0002] Nano is a scale concept, which is one-billionth of a meter, and has no physical connotation. When the material reaches the nanometer scale, the properties of the material will change suddenly, and special properties will appear. Since the 1990s, nanotechnology has shown bright application prospects due to its novelty and uniqueness, and has achieved a series of key breakthroughs. Due to factors such as this field has a huge imagination space, development prospects, and potential scope for huge changes. , its research and application has been widely and highly concerned by countries all over the world. [0003] Before elaborating on adding nanomaterials to change the sealing performance of glass, it is necessary to introduce the characteristic structure of nanocry...
