preparation example Construction
[0032] The preparation process of the projection glass screen 100 includes:
[0033] Step S1: After roughening the first surface of the transparent glass substrate, spraying a nanometer self-cleaning coating with photocatalysis;
[0034] Preferably, the light transmittance of the transparent glass substrate is greater than 85%, preferably greater than 90%.
[0035] More preferably, after the first surface is roughened, the roughness is 0.05-1.5 μm, or 0.1-1.3 μm, or 0.3-1.1 μm, or 0.5-1.0 μm, or 0.7-0.9 μm.
[0036] Further, the rough surface treatment is an etching method, and the depth of the groove after etching is 0.3-0.8 μm, or 0.4-0.7 μm, or 0.5-0.6 μm; the width of the groove is 130-160 μm, or 135-155 μm , or 140-150 μm, or 143-147 μm.
[0037] Further, it also includes: tempering the transparent glass substrate treated by the etching method, so as to enhance the hardness of the transparent glass substrate and improve the safety of use.
[0038] Alternatively, the ro...
Embodiment 1
[0070] The present embodiment provides a spectral light-absorbing coating, which includes by weight parts:
[0071] 90 parts of metal color paste, 30 parts of synthetic resin, 6 parts of additives.
[0072] Wherein, metal color paste comprises by weight parts:
[0073] 65 parts of silver metallic pigment, 13 parts of yellow metallic pigment, 4 parts of red metallic pigment, 3 parts of blue metallic pigment, 5 parts of green metallic pigment.
[0074] The preparation method of this spectral light-absorbing coating is:
[0075] a. Grinding the resin-wrapped silver flakes into fine powders to obtain silver metallic pigments.
[0076] b. Attach the yellow light-color film, red light-color film, blue light-color film and green light-color film to the surface of the metal silver sheet respectively. The ratio of the thickness of the metal silver sheet to the light-color film is 30:1, tear off After filming, grind into powder to obtain yellow metallic pigment, red metallic pigment,...
