Abstract
An anti-glare glass of the present disclosure has excellent anti-glare properties and visibility by forming glass in which polysilazane-derived surface unevenness are applied to a glass surface without mixing a heterogeneous element, and has remarkably improved wear resistance and durability since the polysilazane is changed for glass on the glass surface by thermal treatment.
Claims7
A method of manufacturing an anti-glare glass, the method comprising:
- S1) preparing a coating composition consisting of 2 to 20 wt. % of polysilazane having a weight average molecular weight equal to or less than 30,000 g/mol and a residual amount of a single solvent;
- S2) spraying and coating the coating composition onto a glass surface;
- S3) removing the solvent of the coating composition coated on the glass surface within 60 seconds to form an uneven layer on the glass surface, wherein the unevenness is caused by the polysilazane;
- and
- S4) performing heat treatment, wherein the anti-glare glass has haze of 1 to 5% and transmittance equal to or greater than 90%.
