Embodiment

[0022] A preparation method of a spectrally selective reflective colorful coating film material is: on the corona surface of the high-transmittance optical-grade transparent PET film, the thickness of the high-transmittance optical-grade transparent PET film is selected as 20 μm, and the spectrum is selected by MG coating. Sexy colorful reflective coating, coating thickness 0.5μm, the coating surface passes through the conveying device and passes through the oven to evaporate excess solvent, and the oven temperature is 100°C; the baking time is 50S, and the coated surface passes through the conveying device and passes through the UV light curing machine to fix the pitch gradient , where the radiation intensity of the UV light curing machine is 300mj / cm², the colorful coating film material with spectral selective reflection can be obtained.

[0023] Wherein the ratio of raw materials of the spectrally selective colorful reflective coating of embodiment 1-3 is shown in Table 1: ...

Abstract

The invention discloses a preparation method of a film material with a spectrally selective reflection colorful coating, which comprises the steps of coating a spectrally selective colorful reflection coating on a corona surface of a high-transmittance optical-grade transparent PET film through MG, and evaporating excessive solvent on the coating surface through an oven by virtue of a conveying device, wherein the baking time is 30-60 seconds, and the coating surface passes through the conveying device and passes through a UV light curing machine to fix the screw pitch gradient so as to obtain the film material with the spectrally selective reflection colorful coating. The preparation process is simple, the used polymer monomer is polymerized into a cross-linked polymer network, and good thermal mechanical stability and good weather resistance are achieved. Compared with a multi-layer extrusion and coating process, the cost is reduced; the polymer monomer has several components, self-assembly of two or more molecules can be achieved, a molecular density gradient difference is formed, high and low refractive index matching in the same high polymer can be achieved through cross-linking of chiral molecules, accurate waveband reflection is achieved, and a colorful function is achieved.

Description

technical field [0001] The invention relates to the field of automotive film materials, in particular to a preparation method and application of a colorful coating film material with spectral selective reflection. Background technique [0002] At present, there are relatively few studies on colorful films on the market. Most of the colorful films on the market are dominated by the products of 3M Company in the United States. Difference between high and low refractive index. The colorful change effect of the colorful film realized by the high and low refractive difference is soft, but the colorful reflective effect is weak, and the production often requires hundreds of layers, the process is complicated, the equipment investment is high, the efficiency is low, and the cost is high. There is also a multi-layer magnetron coating process introduced in Taiwan, my country. Vacuum sputtering of various metals or their oxides on the substrate, using the physical effects of each met...
