Problems solved by technology

However, because the angle-dependent powder in the color-coated steel plate is multi-layer flake, under the action of the angle-dependent powder, the light does not change continuously with the viewing angle, but presents a blunt jumping change.

Embodiment 1

[0049] The invention provides a wear-resistant and scratch-resistant chameleon color-coated board, such as figure 1 As shown, it includes a base material 1 , an adhesive layer 2 and a chameleon paint film 3 which are sequentially stacked.

[0050] The base material 1 is a steel plate. Preferably, the base material 1 is a cold-rolled base material with a thickness of 0.3 mm.

[0051] Such as figure 1 As shown, the adhesive layer 2 is coated on the substrate 1 . Preferably, the adhesive layer is a mixture of epoxy resin, ethylene-octyl acrylate copolymer, polyvinyl alcohol and aluminum oxide particles, with a mass ratio of 10:5:5:2. Epoxy resin and ethylene-octyl acrylate copolymer have good cohesive force, so that the chameleon paint film 3 and the substrate 1 are firmly bonded, and the mechanical properties of the wear-resistant and scratch-resistant chameleon color-coated board are enhanced; at the same time, the polyethylene Under the action of alcohol, the alumina partic...

Embodiment 2

[0062] The present invention provides a wear-resistant and scratch-resistant chameleon color-coated board. The difference from Embodiment 1 is that the reflective layer 33 is not provided separately, but a material with reflective function is selected as the adhesive layer 2 to realize the protection against the pigment light. Reflection, reduce light loss and increase light output rate.

[0063] As an alternative embodiment, the reflective layer 33 may not be provided, but the intensity of light may be enhanced by increasing the proportion of the pigment 322 in the second base material 311 .

Embodiment 3

[0065] The present invention provides a wear-resistant and scratch-resistant chameleon color-coated board. The difference from Embodiment 1 is that the material of the second base material 321 can also be poly-n-butyl methacrylate, or polymethyl methacrylate and polymethyl methacrylate. A mixture of n-butyl acrylate; the thickness of the second film layer 32 can also be other values ​​in the range of 10-14 μm except 12 μm, such as 10 μm, 11 μm, 14 μm, etc., as long as the second film layer 32 and the first film layer can be realized. The reflected light at the 31 interface interferes with the initial light multiple times to eliminate stray light, so as to improve the color purity of the light and ensure that the light intensity does not attenuate.

Abstract

The invention belongs to the technical field of materials and particularly relates to a wear-resisting and scraping-resisting chameleon color-coated board and a preparation method thereof. The wear-resisting and scraping-resisting chameleon color-coated board comprises a base material, an adhesive layer and a chameleon paint film which are stacked sequentially. The chameleon paint film comprises afirst film layer and a second film layer. The first film layer comprises a first base material and a microsphere. The second film layer comprises a second base material and pigment. The refraction index of the first base material is smaller than that of the second base material and smaller than that of the microsphere. Reflection light rays of the pigment at least generate four times of refraction and dispersion on the boundary face of the two film layers, the surface of the microsphere and the surface of the second film layer, multiple colors are presented, and the colors are different at different perspectives. Meanwhile, the refraction effect on the light rays of the microsphere changes continuously, the colors of emergent rays change gradually along with the perspective, and the viewing effect is excellent. Moreover, the chameleon paint film has the scraping-resisting and wear-resisting performance, and the service life of the color-coated board is prolonged. The preparation method of the color-coated board is simple and low in cost.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a wear-resistant and scratch-resistant chameleon color-coated plate and a preparation method thereof. Background technique [0002] The organic paint is compounded on the substrate, and the paint can be in various colors, so the color-coated plate gets its name, and the color-coated plate is also called color steel plate and color-coated steel plate. As a new type of material, color-coated board is widely used in construction, shipbuilding, home appliances, decoration, transportation and other industries because of its good corrosion resistance, bright colors, convenient processing and molding, high strength, and low cost. Due to the different uses of color-coated boards, the requirements for the organic coatings used are also different. If the color-coated boards for building exteriors are exposed to the wind and the sun for a long time, the organic coatings must ...
