Title:
SINGLE-STRENGTHENED-LAYER GLASS AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/215013
Kind Code:
A1
Abstract:
A single-strengthened-layer glass, comprising a glass body and a single strengthened layer formed on the surface of the glass body. The compressive stress of the single strengthened layer is nonlinearly reduced from the surface of the glass body to the interior of the glass body. A compressive stress curve of the single strengthened layer has an inflection point, and the gradient of a first curve section in front of the inflection point is larger than that of a second curve section behind the inflection point. The overall refraction coefficient of the single strengthened layer is nonlinearly reduced from the surface of the glass body to the interior of the glass body, and a refraction coefficient curve of the single strengthened layer has at least two inflection points. Also provided is a method for preparing the single-strengthened-layer glass.
