Embodiment 1

[0023] Embodiment 1 Use the primary color film to reduce the reflectivity of the light incident from the scratch-resistant layer to the aluminum-coated film. 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, the primary color film 21 and the aluminized surface 231 of the aluminized film 23 are combined through the composite layer 22, and then the installation layer 3 is coated on the non-aluminized surface 232 of the aluminized film 23 and compounded with the release film 4, and finally the The anti-scratch layer 1 is coated on the primary color film 21 .

[0024] Select primary color film 21 with visible light transmittance of 30% (visible light reflectance is 7%) and aluminized film 23 with visible light transmittance of 41% (aluminized surface 231 visible light reflectance is 41.1%, non-aluminized surface 232 The re...

Embodiment 2

[0029] Embodiment 2 Utilizes the primary color film to reduce the reflectivity of the light incident from the automobile glass to the aluminized film, the structure is as follows Figure 4 As shown, it includes the anti-scratch layer 1, the aluminized film 23, the composite layer 22, the primary color film 21, the installation layer 3 and the release film 4 in sequence. First, the primary color film 21 and the aluminum-plated surface 231 of the aluminum-plated film 23 are combined through the composite layer 22, then the installation layer 3 is coated on the primary-color film 21 and compounded with the release film 4, and finally the non-plated surface of the aluminum-plated film 23 is The anti-scratch layer 1 is coated on the aluminum surface 232 .

[0030] If you want to reduce the visible light reflectance on both sides of the product at the same time, you can increase the second composite layer 24 and the second primary color film 25 in the core layer 2, use the primary c...

Embodiment 3

[0031] Embodiment three such as Figure 4 As shown, the structure includes an anti-scratch layer 1 , a primary color film 21 , a composite layer 22 , an aluminized film 23 , a second composite layer 24 , a second primary color film 25 , an installation layer 3 and a release film 4 . First, the primary color film 21 and the aluminized surface 231 of the aluminized film 23 are composited through the composite layer 22, and then the second primary color film 25 and the non-aluminized surface 232 of the aluminized film 23 are composited through the second composite layer 24, and then The installation layer 3 is coated on the second primary color film 25 and combined with the release film 4 , and finally the anti-scratch layer 1 is coated on the primary color film 21 .

Abstract

The invention relates to the field of production of films, and particularly relates to an automobile window film capable of reducing visible light reflectance and a preparation process of the automobile window film. The automobile window film comprises an anti-scraping layer, a core layer, a mounting layer and a release film which are connected in sequence, wherein the core layer comprises a deep dyed film, a composite layer and an aluminum laminated film; the aluminum laminated film comprises an aluminum laminated surface and a non-aluminum laminated surface, and the composite layer is connected with the aluminum laminated surface of the aluminum laminated film. The preparation process comprises the following steps: S1, compounding the deep dyed film with the aluminum laminated surface of the aluminum laminated film by the composite layer to form the core layer; S2, coating one side of the core layer with the mounting layer and then compounding with the release film; and S3, coating the other side of the core layer with the anti-scraping layer. According to the invention, the deep dyed film is compounded with the aluminum laminated surface of the aluminum laminated film, so that excellent heat-shielding performance of the aluminum laminated film can be achieved, the visible light reflectance of the whole window film can be effectively reduced, the aluminum laminated film can be well to the field of automobile window films without being limited by the characteristics of light reflection, and meanwhile, explosion-proofing performance, heat insulation performance and the like of the whole window film can be promoted.

Description

technical field [0001] The invention relates to the field of film production, in particular to an automobile window film with reduced reflectance of visible light and a preparation process thereof. 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 inter...
