Alkali aluminosilicate flexible glass containing glass melt active material composition

Abstract

The invention discloses alkali aluminosilicate flexible glass containing a glass melt active substance composition, belonging to the technical field of flexible glass. The flexible glass comprises 3.0-5.0% of a glass melt active substance composition and 95.0-97.0% of an oxide of an alkali aluminosilicate glass batch, wherein the glass melt active substance composition comprises 0.03-0.10% of niobium pentoxide, 0.61-1.52% of antimony trioxide and potassium nitrate; and the oxide of the alkali aluminosilicate glass batch comprises 52.0 to 67.0% of silicon oxide, 4.0 to 23.6% of aluminum oxide,0 to 4.8% of lithium oxide, 7.8 to 15.6% of sodium oxide, 0 to 3.5% of potassium oxide, 0 to 5.5% of calcium oxide, 2.8 to 5.8% of magnesium oxide, 0 to 4.9% of zinc oxide, and 0 to 2% of other components, and the other components are composed of zirconium dioxide, phosphorus pentoxide and / or boron oxide. The forming quality of alkali aluminosilicate ultrathin glass or flexible glass can be effectively improved, the retraction amount of a glass plate surface is reduced, the surface tension and thickness difference of a glass melt are reduced, and the waviness of a plate surface is reduced.

Description

technical field [0001] The invention belongs to the technical field of flexible glass, and relates to alkali aluminosilicate flexible glass, in particular to alkali aluminosilicate flexible glass containing a glass melt active material composition. Background technique [0002] Since the 21st century, with the rapid development of electronic information technology, electronic information display products (such as smart phones, tablet computers, laptops, TVs, smart watches, etc.) Changes, from the era of bulky CRT (cathode ray tube) to the era of thin and light LCD (liquid crystal display) panels, and now we have entered the era of flexible displays, such as flexible OLED (organic light-emitting semiconductor display) products, and even folding mobile phones , folding fans and retractable display screens, the development of the display industry has driven the development and technological innovation of the ultra-thin glass industry. [0003] Ultra-thin glass has become an in...

Problems solved by technology

There are three main problems in the above-mentioned surfactants: 1) poisonous, such as V 2 o 5 , CaF 2 and / or SrCl 2 Volatile matter; 2) coloring, such as MoO 3 , V 2 o 5 、WO 3 Coloring due to variable valence characteristics or color centers, yellow or brown; 3) Crystallization, MoO 3 、WO 3 It is a high atomic number oxide, which is easy to accumulate and cause crystallization. The above three points will seriously affect the forming characteristics, product quality and product application of glass
