Abstract

The invention belongs to the technical field of glass, and particularly relates to energy-saving LOW-E glass which comprises a first glass layer and a second glass layer, and an energy-saving color matching layer, a low-radiation layer and an anti-reflection layer are sequentially arranged between the first glass layer and the second glass layer. The defects of an existing process are overcome; the energy-saving color matching layer, the low-radiation layer and the anti-reflection layer are clamped between the two glass layers, and the external environment is prevented from making contact with the functional layers, so that the service life of the functional layers is prolonged.

Description

technical field [0001] The invention belongs to the technical field of glass, and in particular relates to an energy-saving LOW-E glass and a preparation method thereof. Background technique [0002] Low-E glass, also known as Low-E glass, is a film system product composed of multiple layers of metal or other compounds coated on the glass surface. Its coating layer has the characteristics of high transmission of visible light and high reflection of mid- and far-infrared rays, which makes it have excellent heat insulation effect and good light transmission compared with ordinary glass and traditional architectural coated glass. However, although Low-E glass has a good effect in the early stage of use, its function will continue to decay and lose with the prolongation of use time. Contents of the invention [0003] Aiming at the problems in the prior art, the present invention provides an energy-saving Low-E glass, which solves the defects of the existing technology, and us...
