Abstract

The invention discloses high-transmittance low-reflectivity temperable three-silver low-emissivity glass and a preparation method thereof. The high-transmittance low-reflectivity temperable three-silver low-emissivity glass comprises a glass substrate and a composite film layer plated on the glass substrate, wherein the composite film layer is composed of a first dielectric layer, a first AZO layer, a first functional layer, a second AZO layer, a second dielectric layer, a third AZO layer, a second functional layer, a fourth AZO layer, a third dielectric layer, a fifth AZO layer, a third functional layer, a sixth AZO layer, a fourth dielectric layer and an outermost protective layer which are sequentially arranged on the glass substrate, the first dielectric layer and the fourth dielectriclayer are SiNx layers, the second dielectric layer and the third dielectric layer are ZnO layers, and the first functional layer, the second functional layer and the third functional layer are Ag layers. A prepared glass product has the advantages of low reflectivity, high transmittance, low radiation, good mechanical properties and the like.

Description

technical field [0001] The invention relates to the technical field of steel-three-silver low-emissivity glass manufacturing, in particular to a high-transmittance and low-reflection steel-three-silver low-emission glass and a preparation method thereof. Background technique [0002] With the advancement of science and technology and the improvement of economic level, glass has become an indispensable part of buildings and automobile industries, and it undertakes many important functions, such as: beautifying buildings, meeting the needs of automobile appearance and lighting, and bringing indoor wide field of view etc. However, the sunlight transmittance of ordinary glass is high, while the infrared reflectivity is low, and most of the solar energy and radiant energy can be transmitted through the glass, resulting in poor heat insulation performance. The Low-Emissivity (hereinafter referred to as LOW-E) film has a high reflection effect on solar energy, which greatly reduce...
