Abstract

The invention relates to low-emission glass and a manufacturing method for the low-emission glass. The low-emission glass comprises a glass substrate and a film, wherein the film adheres to the glass substrate; the film comprises a bottom dielectric combination layer, a functional layer, a barrier layer and a top dielectric combination layer which are superposed in sequence; and the bottom dielectric combination layer is attached to the glass substrate. The manufacturing method comprises the following steps of: preparing the glass substrate, depositing the bottom dielectric combination layer, depositing the functional layer, depositing the barrier layer and depositing the top dielectric combination layer. The low-emission glass has the characteristics that the appearance color is good; the film is not easy to drop and cannot be oxidized and the like. The low-emission glass not only can be used singly or hollowly but also can be used in the manner of interlining. Edge film removal is not needed when the low-emission glass is hollowly used, and thereby, the production cost is saved, and the production efficiency is increased.

Description

technical field [0001] The invention relates to a special glass and a manufacturing method thereof, in particular to a silver-free low-emission glass and a manufacturing method thereof. Background technique [0002] At present, there are two main methods of producing low-emissivity coated glass. One is on-line coating, which generally refers to spraying certain chemical reagents on the glass surface with high temperature according to a certain ratio during the production process of float glass, so that the glass surface forms a compound film with a certain low-radiation function, which has better Physical and chemical properties, so it is more suitable for promotion in the civilian field. The other is off-line coating. Generally, it refers to plating silver or other metal compounds with extremely low emissivity on the glass surface by means of vacuum magnetron sputtering in a certain proportion. For example, the Chinese invention patent application with the application nu...
