Abstract

The invention discloses an XIR film heat-reflective laminated energy-saving glass comprising sequentially laminated components of a first glass layer, a first PVB film layer, an XIR film layer, a second PVB film layer, and a second glass layer. According to the invention, a solar spectrum selective permeation problem of the laminated glass is solved. Therefore, purposes of refrigeration energy consumption reducing and energy saving are achieved. Selective permeation of solar spectrum by the laminated glass is realized. Compared to common laminated glass, the laminated glass provided by the invention has a spectrum selectivity characteristic. A relatively high permeation is maintained, and a low shading coefficient is obtained. When a visible light transmittance is 70%, a shading coefficient is only 0.38.

Description

technical field

[0001] The invention relates to a glass, in particular to an XIR film heat reflection laminated energy-saving glass. Background technique

[0002] Ordinary laminated glass in traditional technology cannot achieve selective transmission of solar spectrum. The disadvantage of existing technology is that ordinary laminated glass cannot achieve selective transmission of solar spectrum, while XIR film can reflect infrared rays and block ultraviolet rays. It has good heat insulation effect and is a new type of environmental protection and energy-saving material. If it can be applied to glass to form laminated glass, it can improve multiple properties of glass. Contents of the invention

[0003] The object of the present invention is to provide a kind of XIR film heat reflection laminated energy-saving glass.

[0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions:

[0005] An XI...

Embodiment Construction

[0009] The technical scheme of the present invention is described in detail below in conjunction with the embodiment shown in the accompanying drawings:

[0010] as attached figure 1 As shown, the XIR film heat-reflective laminated energy-saving glass of the present invention includes a first glass layer, a first PVB film layer, an XIR film layer, a second PVB film layer and a second glass layer laminated in sequence.

[0011] Compared with the traditional laminated glass, the laminated glass designed by the present invention solves the problem of selective transmission of the solar spectrum, achieves the purpose of reducing refrigeration energy consumption and saving energy, and realizes the selective transmission of the laminated glass to the solar spectrum. The more common laminated glass has the characteristics of spectral selection, and can obtain a very low shading coefficient while maintaining a high transmittance: when the visible light transmittance is 70%, the...
