Problems solved by technology

As far as the development trend of heat insulation film products is concerned, good heat insulation performance must also have high visible light transmittance. At present, precious metals and TiO2 can achieve this requirement. 2 Or a multilayer composite film of a dielectric film such as ITO, but due to TiO 2 The deposition rate of the dielectric film is very low, that is, the production efficiency is very low and the price is very high, which is not conducive to popularization
As far as the general metal film is concerned, high visible light transmittance and high heat insulation performance are contradictory. Through appropriate methods and processes, noble metal Ag film can achieve high visible light transmittance and good insulation performance to varying degrees. Thermal performance, but the metal Ag film has weather resistance problems such as easy oxidation and vulcanization

Abstract

The invention relates to a Ag alloy heat-insulating film and a preparation method thereof. The heat-insulating film comprises a base material PET (Polyethylene Glycol Terephthalate), a first NiCr film coating layer, a second Ag alloy film coating layer, and a third NiCr film coating layer. The preparation method for the heat-insulating film comprises the following steps: on a reel-to-reel flexible magnetron sputtering coating machine, when the base material PET is rotated along with a film coating roller, plating NiCr, Ag alloy and NiCr three film layers on the other side of the base material PET through film coating areas of different targets. The Ag alloy heat-insulating film disclosed by the invention has the advantages of being high in visible light transmission, high in infrared ray resistance, good in weather resistance, high in production efficiency, low in cost and the like, so that the application field of the heat-insulating film is widened, the market area is enlarged, and development of the heat insulating film towards energy conservation and environment protection direction is promoted.

Description

technical field [0001] The invention belongs to the field of building and automobile film, and in particular relates to an Ag alloy heat-insulating film with spectrally selective permeability and a preparation method thereof. Background technique [0002] With the development of science and technology, the improvement of people's living standards and the concept of "low-carbon life", the performance requirements for thermal insulation films are getting higher and higher, and the demand is gradually increasing. At present, thermal insulation film has been widely used in the curtain wall glass of large buildings and the window glass of automobiles. Using it on the curtain wall glass of a large building can greatly reduce the cost of air conditioning, and make the appearance of the building have a beautiful color. At present, most of the car window glass is pasted with thermal insulation film, which reduces the damage of ultraviolet rays to the human body and interior decorati...
