A TEMPERABLE LOW-EMISSIVITY GLASS WITH REDUCED HAZING AFTER THERMAL TREATMENT AND A METHOD FOR PREPARING THE SAME

摘要

PURPOSE: A low-emissivity glass and a manufacturing method thereof are provided to secure the excellent visible light transmission rate, and to prevent the hazing of the glass. CONSTITUTION: A low-emissivity glass capable of performing a heat treatment comprises the following: a first dielectric layer coated on a glass substrate; a first haze preventing layer containing a Zn based oxide including more than one element selected from the group consisting of Sn, Nb, Al, Sb, Mo, Cr, Ti, and Ni; a functional reflecting metal layer reflecting far infrared rays or solar radiation rays; a second haze preventing layer containing the Zn based oxide including more than one element selected from the group consisting of Sn, Nb, Al, Sb, Mo, Cr, Ti, and Ni; and a second dielectric layer.
