A TEMPERABLE LOW-EMISSIVITY GLASS WITH ENHANCED DURABILITY AND A METHOD FOR PREPARING THE SAME

摘要

A temperable low-emissivity glass showing excellent durability and a manufacturing method thereof are provided to show excellent handling and storage properties as well as durability and to secure visible light transmission rate of 70% or greater. A temperable low-emissivity glass comprises: a first dielectric layer coated on a glass substrate; a first functional reflection metal protective layer containing Ni-Cr alloy or a 50 and less mol% oxidized or nitrified Ni-Cr alloy; a functional reflection metal layer for reflecting infrared ray or the solar radiant light; a second functional reflection metal protective layer containing Ni-Cr alloy or a 50 and less mol% oxidized or nitrified Ni-Cr alloy; a second dielectric layer; and an uppermost protective layer. The first and second dielectric layers are independently made of Silicon nitride or oxide.
