Abstract

The invention discloses a window film core functional layer and a preparation method thereof. The window film core functional layer comprises a PET substrate thin film, and a first transparent oxide layer, a first composite metal layer, a second transparent oxide layer, a second composite metal layer, a third transparent oxide layer and an outer side seal layer which are sequentially deposited from bottom to top by magnetron sputtering. The preparation method of the window film core functional layer comprises the step of sequentially performing coating in six chambers of a six-chamber coiling type magnetron sputtering coating machine or a double-roller and three-chamber coiling type magnetron sputtering coating machine to form the magnetron sputtering layers. The window film core functional layer has the beneficial effects that an Au layer with the thickness of 3-10nm is deposited at the outer side of the third transparent oxide by magnetron sputtering, so that the infrared reflectivity is increased to 90% from 80%; the reflectivity of visible light is reduced while the infrared reflectivity is increased, so that the temperature in a chamber using the window film core functional layer is maintained to be constant while lighting is not influenced.

Description

technical field [0001] The invention relates to the field of optics, in particular to a core functional layer of a window film and a method for preparing the core functional layer of the window film. Background technique [0002] In recent years, the domestic magnetron sputtering window film industry has just emerged. Single-silver, double-silver and even triple-silver structures can be widely used in the production of window films. However, in industrial production, the magnetron window film needs to be coated in the later stage of production. The process is compounded, which makes the window film inevitably come into contact with the air, and even the contact with the human body during the handling process will accelerate the oxidation of the window film. In the low-e glass industry, the anti-oxidation work of the coating is equally important. They will cover a layer of plastic film on the coated glass, which will be protected against oxidation during the transportation of...
