Embodiment 1

[0026] Embodiment 1 The primary color film is used to reduce the reflectivity of the light incident from the scratch-resistant layer to the aluminum-coated film, and the structure is as follows figure 2 As shown, the anti-scratch layer 1, primary color film 21, composite layer 22, aluminized film 23, installation layer 3 and release film 4 are included in sequence. First select the aluminized film 23 to reduce the reflectance of visible light. The visible light transmittance of the aluminized film 23 is 41% (the visible light reflectance of the aluminized surface 231 is 41.1%, and the reflectance of the non-aluminized surface 232 is 28.4%). The expected visible light reflectance of the target product is 9.5%; according to the formula

Abstract

The invention relates to the field of thin film production, in particular to a method for lowering the visible light reflectivity of a vacuum heat evaporation film. The method comprises the following steps that an aluminum plating film requiring the visible light reflectivity reduction is selected, and a visible light reflectivity expected value of a target product is set; the proper original color film is selected according to a formula; the original color film and the aluminum plating surface of the aluminum plating film are compounded through a compounding layer, and a core layer is formed; an installing layer firstly coats one side of the core layer and is compounded with a parting film; an anti-scratching layer coats the other side of the core layer; a target product is formed. A formula is used for selecting the original color film; the visible light reflectivity of the produced target product approaches to the expected value; a great number of experiment consumption materials, labor and time can be reduced; the original color film and the aluminum plating surface of the aluminum plating film are compounded; the excellent heat insulation performance of the aluminum plating film can be realized; the visible light reflectivity of a whole of a window film is effectively reduced, so that the aluminum plating film can be better applied to the field of automobile window films; the limitation due to reflection features can be avoided.

Description

technical field [0001] The invention relates to the field of film production, in particular to a method for reducing the visible light reflectance of a vacuum thermal evaporation film. Background technique [0002] Vacuum thermal evaporation film belongs to the second generation of window film products, and the base material uses aluminized film. This type of film was produced in the early 1990s. The vacuum thermal evaporation process is to evaporate the aluminum layer on the substrate to achieve the effect of heat insulation. This kind of film has entered the field of what we usually call metal film, which has long-lasting heat insulation, but its outstanding weakness is that it is highly reflective and interferes with the line of sight. The relevant regulations of the Ministry of Public Security have requirements for the reflectivity of visible light inside and outside the car window film. The design of window film products should also consider that the internal reflectio...
