Abstract

The invention discloses a preparation method of flexible ultrathin glass. The glass is prepared from SiO2, Al2O3, Na2O, K2O, MgO, P2O5, B2O3, Sb2O3, Er2O3 and SrF. The above substances are melted at ahigh temperature to form homogeneous and synergistic effects, so the excellent characteristics of the substances are effectively reflected, and the strength and the toughness of the flexible ultrathin glass is effectively enhanced.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a preparation method of flexible ultra-thin glass. Background technique [0002] With the continuous advancement of science and technology, smart electronic products are becoming thinner and smarter, especially electronic wearable devices, bendable smartphones and curved surface display technology with a strong sense of reality, which endow new flexibility to the glass that is the basis of electronic display. However, ordinary glass is a typical brittle material with low tensile strength, and it is easy to break under the action of external force and affect its use. Therefore, there is an increasing demand for flexible ultra-thin glass in industrial production. Contents of the invention [0003] In order to make up for the defects of the prior art, the invention provides a method for preparing flexible ultra-thin glass. [0004] The technical problem to be solved by ...
