Abstract

The invention discloses a window film core functional layer and a method for manufacturing the window film core functional layer. The window film core functional layer comprises a PET base thin film and a magnetron sputtering layer arranged on the PET base thin film, wherein the magnetron sputtering layer comprises a first transparent oxide layer, a first composite metal layer, a second transparent oxide layer, a second composite metal layer and a third transparent oxide layer which are sequentially arranged on the PET base thin film from bottom to top; and the method for manufacturing the window film core functional layer comprises the following step of sequentially carrying out magnetron sputtering film plating in five chambers of a five-chamber winding type magnetron sputtering film plating machine to form the magnetron sputtering layer. The window film core functional layer has the beneficial effects that the infrared light reflectivity is improved and the reflectivity of visible light is reduced, and the consumption of energy sources is saved; a metal layer is deposited and sealed at the upper part of an Ag layer so that the Ag layer is not contacted with oxygen and is not oxidized and the service life of the window film core functional layer is guaranteed; and the window film core functional layer can be manufactured in the five magnetron chambers in one step and the production efficiency is high.

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 manufacturing the core functional layer of the window film. Background technique [0002] In the United States, magnetron sputtering technology has been widely used in the coating process of various substrates and materials since the 1980s, and represents the most advanced technology in the coating process. However, due to the long-term technical blockade, the relevant technology was introduced in the domestic market around 2000, and the rise of the touch screen industry around 2010 made the domestic market gradually familiar with this technology. The glass window film industry involved in this method is an important application of the roll-to-roll coating machine, but the window film product produced by this process is still in its infancy in China. [0003] At present, the production of domestic window films is still dominated by ...
