Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in the prior art, dark glass is used as building exterior wall or door and window glass to achieve the effect of blocking solar heat radiation, sacrificing most of the sunlight irradiation of visible light, and blocking heat. The function of radiation is limited, and the glass coated with ITO film cannot fully reflect the infrared

Embodiment Construction

[0006] Such as figure 1 As shown, a kind of insulating infrared radiation material for architectural glass of the present invention is composed of a base layer 1 and a functional layer 2, the base layer 1 is made of a transparent material, the functional layer 2 is made of a metal material, and the functional layer 2 is compounded on On the base layer 1, the thickness of the functional layer 2 is between 3 nanometers and 2000 nanometers, and the functional layer is a single-layer metal film. Such as figure 2 As shown, the functional layer 2 may also be composed of multiple layers of metal films and dielectric films. The method of electron beam evaporation or sputtering in the prior art can be used to compound the functional layer to the base layer. In a preferred embodiment of the present invention, the base layer 1 adopts a titanium dioxide film substrate, and the functional layer 2 adopts a single-layer silver metal film with a thickness of 8 nm to 30 nm. In another pre...

Abstract

The infrared radiation-isolating film material for building glass consists of base layer and functional layer, the base layer is transparent medium film substrate material for improving the mechanical property of the film and the functional layer has thickness of 3-2000 nm and comprises one or more medium film with at least one layer of metal medium film or dielectric film. In the functional layer or base layer, there is titania, zirconium oxide or other strong ultraviolet absorbing medium to make the film possess some ultraviolet protecting capacity at the same time. The material may be madeto cover partial or whole ultraviolet area by means of regulating the nanoparticles zie. The material has high transparency to visible light, complete infrared radiation isolating function and high ultraviolet-proof function, and may be used to reach the functions of saving energy and protecting health.

Description

Technical field: [0001] The invention relates to a composite thin film material, in particular to a composite thin film material for building glass to isolate infrared radiation. Background technique: [0002] Most of the existing architectural glass is white glass or colored glass, and there is also glass with coating on the surface. The main purpose of coating is mostly decoration. In order to block the thermal radiation of sunlight (the spectrum of thermal radiation corresponds to a range of one to several tens of microns), dark glass is generally used as building exterior walls or door and window glass, and glass coated with ITO film is also used. The transparency of visible light is very good. Well, about 80% reflective to IR. Invention content: [0003] The technical problem to be solved by the present invention is: in the prior art, dark glass is used as building exterior wall or door and window glass to achieve the effect of blocking solar heat radiation, sacrific...
