Embodiment 1
[0038] This example is a metal-colored anti-light projection imaging coating, comprising film forming material, surfactant, colored pigment, inorganic pigment, high reflective pigment, diffuse reflective filler, melody reflective filler, and dispersion medium.
[0039] The film formation material, surfactant, colored pigment, inorganic pigment, high reflective pigment, diffuse reflective filler, mesh diffusion filler, and dispersion medium in the content of the metallic anti-light projection imaging coating are in turn weight. Comparison: 20-40: 5-10: 8-25: 0.1-0.9: 1-9: 5-15: 4-12: 10-35.
[0040] In this embodiment, the surfactant comprises a pH regulator, a wetting dispersant, a leveling agent, a defoamer, a preservative, a film forming aid, and a stream modifier. In a further technical solution, the pH adjusting agent, a wetting dispersant, a leveling agent, an antifoaming agent, a preservative, a film forming aid, and a rheological auxiliary agent are in the same amount of su...
Embodiment 2
[0059] The present embodiment is a method for preparing a metal-colored anti-light projection imaging coating, and the specific steps are:
[0060] S100. Add the dispersion medium to the dispersing tank to stir;
[0061] S200. Slowly add a wetting dispersant, graft, defoamer, preservative, and mix;
[0062] S300. Slowly add colored pigments in the tank, inorganic pigment, diffuse reflective filler, and uniform stirring in the tank, inorganic pigment, diffuse reflective filler and uniform stir;
[0063] It should be noted that S100, S200 is the same as the stirring speed of S300, and the specific stirring speed is selected between 100-300 rpm, and the stirring speed at this time is 200 rpm.
[0064] S400. Disperse the components added to the dispersed tank;
[0065] It should be noted that the dispersion speed in step S400 is set to 2000 to 4000 rpm, dispersed 20-40 minutes, and the stirring speed at this time is 3000 rpm, dispersion for 30 minutes.
[0066] S. Slowly add film form...

Abstract
The invention discloses a metallic color anti-light projection imaging coating and a preparation method thereof. The metallic color anti-light projection imaging coating comprises a film-forming substance, a surfactant, a coloring pigment, an inorganic pigment, a high-reflective pigment, a diffuse reflection filler, an extinction diffuse reflection filler and a dispersion medium, wherein the weight ratio of the film-forming substance to the surfactant to the coloring pigment to the inorganic pigment to the high-reflective pigment to the diffuse reflection filler to the extinction diffuse reflection filler to the dispersion medium is (20-40): (5-10): (8-25): (0.1-0.9): (1-9): (5-15): (4-12): (10-35). The metal-color anti-light projection imaging coating prepared according to the technical scheme can be coated on flat wall surfaces, gypsum boards, wood boards and plastic boards by using brush coating, roll coating and spray coating processes, and by utilizing a high reflection coefficient and a diffuse reflection principle, a projection screen with high gain (2.5 or above), high brightness, high contrast, high saturation, large visual angle (the visual angle can reach 90 degrees or above) and high light resistance can be formed, and the projection screen has an excellent image imaging effect no matter in dark and semi-dark environments or bright environments.
Description
Technical field [0001] The present invention relates to the field of optical imaging techniques, and more particularly to a metal anti-light projection imaging coating and a preparation method. Background technique [0002] Nowadays, projection technology has been widely used in people's lives and work, especially frequent applications in large conference rooms, command control centers, training education structures, exhibition halls, exhibition halls, airports, and window. [0003] Many units who have purchased a projector will always find that their machine is not bright enough, resulting in a good effect when the ambient source is sufficient. Even if you bought a professional projection curtain, it is difficult to achieve the expected results. Why do there happen to problems, because prior art solutions are often efforts to improve the gain of projection, and the reality is taking technical means to improve gain, the key is how to solve a series of problems that occur after in...
