Description
Technical Field
The invention relates to the technical field of composite films, in particular to a preparation method of a low-radiation composite film.
Background
The low-radiation film is developed in the development process of large-area glass coating, and hollow glass and vacuum glass have a certain energy-saving and heat-insulating effect due to the fact that the hollow glass and the vacuum glass effectively prevent convection and conduction of heat and have a certain energy-saving and heat-insulating effect, and have widely entered daily production and life of people. But the energy-saving effect of the common hollow glass is only 60% 2, and the heat-insulating effect is not obvious. The low-radiation glass (low-e glass) has larger visible light transmittance and smaller infrared reflection coefficient, can allow more than 80% of visible light to enter the room, and reflects more than 90% of sunlight and infrared rays radiated by indoor objects, has more than 75% of energy-saving effect, and can meet the requirements of lighting, decoration, light pollution prevention and the like of buildings. The low-radiation glass is the most ideal energy-saving material for windows due to excellent energy-saving and environment-friendly performance, and the low-radiation film glass is widely applied to building energy-saving window glass due to the advantages of reflecting infrared rays and ultraviolet rays, having better transmittance for visible light and the like.
The preparation methods of the low-radiation film are divided into two major categories, namely an online method and an offline method. According to different methods, the low-radiation film is also divided into two types of different structures, namely an online film and an offline film, the online method adopts a high-temperature pyrolysis method of chemical tear deposition to produce the low-radiation film, the offline method is a method for plating the low-radiation film on the surface of glass by magnetron sputtering and other methods after the glass is offline, the film plated by the method is called the offline film, also called a soft film, the structure of the offline film is generally a sandwich structure of a dielectric layer/a metal layer/a dielectric layer (DMD), a metal shell adopts gold, silver, aluminum and the like, the thickness is generally within 20nm, and the metal film can form a continuous film and is transparent under the thickness. Thus, most of visible light can be allowed to pass through, but most of infrared light and ultraviolet light can be reflected off, and since the metal film is not wear-resistant, dielectric films need to be plated on two sides of the metal film. Generally, a metal oxide film (TiOx, SnOx, Znox, etc.) or a similar insulating film, and an inner dielectric film are used to improve the adhesion between silver and the glass surface and to adjust the optical properties and color of the film system. The outer dielectric film is both an antireflective film and a protective film. It can improve the solar transmittance in this wavelength range while protecting the metal film. Both sides are less than one quarter of the optical wavelength thick. Also, the higher the refractive index of the dielectric thin film, the higher the transmittance of the entire film.
In the process of implementing the invention, the inventor finds that at least the following problems in the prior art are not solved: 1. the whole thickness of the film is higher, so that the light transmittance of the film is influenced, and the service performance of the film is reduced; 2. in the process of preparing the Ag layer, oxidation easily occurs, so that the oxidation and TiO are influenced2The binding rate of (4).
