Problems solved by technology

Existing white light-emitting products spray white paint with a specific film thickness on the transparent product, and match it with a backlight base plate that can emit white light. When the light is turned on, the product can see the white light from the front, but when the light is turned off by this method, only the light-transmitting area of ​​the product can be seen. It is ordinary white, without the high-grade texture of metal plating silver, which cannot meet the appearance requirements of high-end luminous products
The PVD evaporative indium plating process can meet the requirements of the frontal observation of the product when the light is turned off, and the light-transmitting area of ​​the product has a very good metallic silver color. However, when matched with a backlight that can emit white light, the light-transmitting color is obviously yellow, and the color temperature of the light-transmitting color is below 4500K. , cannot meet the requirements of white light transmission and light color temperature of 5200 ~ 7200K
No matter how to adjust the thickness of the PVD indium coating layer, the vacuum degree of the coating film, the position of the tungsten wire of the evaporation source, the number of tungsten wires, and the evaporation parameters of the coating film, etc., it is not enough to make the PVD indium coating layer transparent.

preparation example Construction

[0054] The preparation method of the composite film layer that can transmit white light comprises the following steps:

[0055] Mix transparent plastic with blue pigment and purple pigment (add 0.5-8 parts of blue pigment and 0-2 parts of purple pigment to 100 parts of transparent plastic), and inject to form transparent panel 1;

[0056] On one side of the transparent panel 1, indium plating is evaporated by physical vapor deposition (PVD) to form an indium plating layer 3;

[0057] A transparent paint is coated on the indium-plated layer 3 to form a transparent paint layer 4, that is, a composite film layer that can transmit white light is obtained.

[0058] Examples of transparent plastics are polycarbonate, PVC, PET or PP transparent plastics.

[0059] The transparent coating that forms the transparent coating layer is a mixture of transparent, liquid epoxy resin or acrylic resin as the main component, which can be used in various coating processing operations. to the pr...

Embodiment 1

[0074] The preparation method of the white light-permeable composite film layer of this embodiment is specifically as follows:

[0075] Mix 100 parts of transparent polycarbonate plastic and 4 parts of sky blue pigment (average particle size is 300nm) with CMYK value of C45 M10 Y10K0, and inject to form a transparent panel with a thickness of 5mm;

[0076] On one side of the transparent panel, evaporate indium plating by physical vapor deposition to form a PVD indium plating layer with a thickness of 18nm;

[0077] The transparent paint is sprayed on the PVD indium-plated layer, and after curing, a transparent paint layer with a thickness of 20 μm is formed to obtain a white light-transmitting composite film layer.

Embodiment 2

[0079] The preparation method of the white light-permeable composite film layer of this embodiment is specifically as follows:

[0080] Mix 100 parts of transparent polycarbonate plastic, 3 parts of azure pigment (average particle size 500nm) with CMYK value of C70 M10 Y0 K0 and 0.5 parts of maroon pigment (average particle size of 400nm) with CMYK value of C45 M70Y50 K0 , injection molding to form a transparent panel with a thickness of 7mm;

[0081] Spray transparent primer slurry on one side of the transparent panel, and form a transparent primer layer with a thickness of 20 μm after curing;

[0082] Evaporate indium plating on the transparent primer layer by physical vapor deposition to form a PVD indium plating layer with a thickness of 25nm;

[0083] The transparent paint is sprayed on the PVD indium plating layer, and after curing, a transparent paint layer with a thickness of 25 μm is formed to obtain a white light-transmitting composite film layer.

Abstract

The invention belongs to the technical field of light emitting, and relates to a composite film layer capable of transmitting white light. The composite film layer capable of transmitting white light comprises a transparent panel and an indium plating layer, wherein the transparent panel is closer to the white light source relative to the indium plating layer; and the transparent panel is formed by mixing transparent plastic and blue pigment and performing injection molding, or the transparent panel is formed by mixing transparent plastic, blue pigment and purple pigment and performing injection molding. According to the invention, a color complementing principle in chromatics is utilized, and the transparent panel containing the blue pigment or containing the blue pigment and the purple pigment is attached to one side of the indium plating layer, so that the composite film layer can transmit white light, and the color temperature value of the transmitted white light is 5200-7200K.

Description

technical field [0001] The invention belongs to the technical field of light emission, and relates to a white light-permeable composite film layer and a preparation method and application thereof. Background technique [0002] With the development of energy saving, environmental protection and intelligence in the automotive industry, vehicle-mounted luminous wave-transmitting products will become more and more popular, such as luminous grilles, luminous signs, luminous interior and exterior decorations, etc. Luminous grilles and luminous signs require products to emit white light, and some It is also necessary to integrate radar to cooperate with driving. Existing white light-emitting products spray white paint with a specific film thickness on the transparent product, and match it with a backlight base plate that can emit white light. When the light is turned on, the product can see the white light from the front, but when the light is turned off by this method, only the li...
