preparation example Construction

[0096] The schematic flow chart of the preparation method of colorful material of the present invention is as figure 1 , 2 Shown, the preparation method of colorful material comprises the steps:

[0097] 1) The coating composition A is coated on the substrate 2 through the wire rod 1, and the periodically arranged gaps (pitch 4) between the wire rods are used to pass through the periodically arranged gaps when the nanospheres 3 are coated , after the solvent is completely dried and volatilized, the nanospheres 3 form a regular and periodic arrangement on the surface of the polymer substrate;

[0098] 2) Coat the coating composition B on the coating substrate 7, dry until the solvent is completely volatilized, and attach the coating composition A coating surface 6 obtained in step 1) to form the coating composition B coating surface 8. The coating surface 6 of the coating composition A is bonded to the coating surface 8 of the coating composition B, and UV curing is carried o...

Embodiment 1

[0100] Coating composition A includes: 5 parts of nanospheres (JNS-PC01-100, diameter 100 nm), 0.01 part of dispersant Anti-Terra-203, 0.05 part of leveling agent FS-3100, adding water to make coating The total solid content of the composition is 5 wt%, and it is stirred and mixed evenly. Coating composition A prepared above was evenly coated on PET film (thickness 50 μm) with a wire rod (wet thickness 20 μm, pitch 1 μm), and the coating dry thickness was 1 μm to complete the periodicity of the nanostructure. Arranged neatly; then dried at 100°C for 2 minutes. Coating composition B includes: 10 parts of trimethylolpropane triacrylate (SR351 NS), 0.5 parts of photoinitiator Irgacure 184, 1 part of adhesion promoter Silquest A-1170, leveling agent FS- 3100 is 1 part, add water to make the total solid content of the coating composition 30 wt%, stir and mix evenly. Coating composition B prepared above was uniformly coated on PET film (thickness 100 μm) with a doctor blade, the c...

Embodiment 2

[0102] Coating composition A includes: 10 parts of nanospheres (JNS-PC01-150, diameter 150 nm), 1 part of dispersant Anti-Terra-205, 2 parts of leveling agent FS-3100, adding water to make coating The total solid content of the composition is 10 wt%, and it is stirred and mixed evenly. Coating composition A prepared above was evenly coated on PET film (thickness 100 μm) with a wire rod (wet thickness 50 μm, pitch 5 μm), and the coating dry thickness was 5 μm to complete the periodicity of the nanostructure. Arranged neatly; then dried at 100°C for 2 minutes. Coating composition B includes: 20 parts of trimethylolpropane triacrylate (SR351 NS), 1 part of photoinitiator Irgacure 184, 2 parts of adhesion promoter CoatOSil MP 200, leveling agent FS-3100 For 2 parts, add isopropanol to make the total solid content of the coating composition 30 wt%, stir and mix evenly. The above-prepared coating composition B was uniformly coated on the PC film (thickness 100 μm) with a spatula t...

Abstract

The invention discloses a coating composition for a colorful material, a colorful material and a preparation method thereof. The preparation method of the colorful material of the present invention includes the following steps: 1) Coating the coating composition A on the substrate through a wire rod, using the periodically arranged gaps between the wire rods to allow the nanospheres to pass through during coating With this periodically arranged gap, after the solvent is completely dried and volatilized, the nanospheres form a regular and periodic arrangement on the surface of the polymer substrate; 2) Coating the coating composition B on the substrate, drying and waiting The solvent is completely volatilized, pasted on the coating surface of the obtained coating composition A, and subjected to ultraviolet curing to obtain the colorful material. The preparation method of the colorful material of the present invention adopts ultraviolet curing, has high production efficiency and simple equipment, and can selectively transfer the coating layer of nanospheres to an ideal and arbitrary purpose substrate. It has various mechanical properties and effects, and has excellent practicability.

Description

technical field [0001] The invention relates to the technical field of colorful materials, in particular to a coating composition of colorful materials, colorful materials and a preparation method thereof. Background technique [0002] Colorful materials, also known as colorful materials, rainbow materials, etc., refer to materials that show different colors as the viewing angle changes with the naked eye. [0003] As far as the preparation and development technology of colorful materials is concerned, the first is to use the principle of light interference generated by a multi-layer structure composed of different refractive indices. 3M uses this principle to achieve colorful effects, that is, as the viewing angle of human eyes changes, the material can produce rainbow and colorful changes. The colorful effect of this technology is obvious, but obviously its process is complicated, the equipment cost is high, and the production efficiency is low; at the same time, the magn...
