Embodiment Construction

[0020] The technical solution of the present invention will be further described below in combination with specific embodiments.

[0021] 1. First put tin foil on a flat iron plate and put it in the oven, bake it to 70-90°C (the actual normal is 75-80°C);

[0022] 2. Next, take 10 parts of polyester polymerizable monomer (a), 10 parts of biphenyl polymerizable monomer (b), 0.3 part of initiator perketene silane acetal, 0.1 part of leveling agent Solvesso150, and cyclohexanone 50 50 parts, 50 parts of toluene, and 0.2 parts of curing agent DACH. Stir and mix the above materials evenly to obtain self-loading nano-polymer functional materials. Use RDS4# wire rod (wet film gap 10 μm) to control the wet film thickness to 2-20 μm uniform Coated on 50μm PET without any HC or primer;

[0023] 3. After the coating is completed, put the wet film on the tin foil or iron plate of the oven, bake for 15 seconds to 1 minute, and remove the solvent. Due to the hydrogen bond between the c...

Abstract

The invention relates to a reflective dazzling colorful film comprising a high transparent thin film substrate and a self-assembled high-molecular functional material coated on the surface of the thinfilm substrate. The self-assembled high-molecular functional material is a high-molecular material with a reflective function, the combination of different polymer monomers, the dosage of an initiator and control of initiation conditions are designed, and self-assembly is performed to obtain the nano-composite high-molecular material with matched high and low refractive indexes; the gradient difference of the molecular density is formed, then the difference of the high and low refractive indexes inside the high-molecular polymer is achieved, the matching of the high and low refractive indexesis achieved, the partial reflection of specific wave bands is achieved, and the dazzling colorful function is realized. The reflective dazzling colorful film has simple process and only needs to coata layer of high-molecular material on the surface of the substrate. The dazzling colorful film has good transparency, high hardness, strong adhesion power and good processability, and is beneficial to realization of industrialization. The prepared thin film is widely used for decoration of 3C products. At the same time, a part of reflected blue light can also improve the color gamut and enhance the brightness of a product light source.

Description

technical field [0001] The invention relates to a reflective colorful film for decoration. Background technique [0002] At present, there are relatively few studies on colorful film related reports. The colorful film on the market is dominated by the products of 3M Company in the United States. They use multi-layer co-extrusion technology and use advanced equipment to superimpose optical films to realize material The difference between high and low refractive index. Multi-layer co-extrusion often requires hundreds of layers, the process is complicated, the equipment investment is high, the efficiency is low, and the cost is high. Therefore, its market application prospect can only be positioned as high-end products. [0003] The invention relates to a reflective colorful film: designing different combinations of polymer monomers, the dosage of initiators and the control of triggering conditions to obtain high and low refractive index matching composite macromolecular func...
