Embodiment 1
[0047] Embodiment 1 A kind of double-layer film preparation method
[0048] Include the following steps:
[0049] (1) Preparation of bottom film 14
[0050] Aluminate YAG phosphor powder, yellow silicate phosphor powder, orange silicate phosphor powder, and red nitride phosphor powder are mixed in any ratio to form mixture A. Add epoxy resin encapsulant to mixture A, mixture A:epoxy resin encapsulant=1:4, the relationship between weight and volume in this step is g:ml, spray on the plane of the board or the wall to form the bottom film 14 .
[0051] (2) Preparation of outer film 15
[0052] In parts by weight, 0.8-1.2 parts of white or transparent defoamer, 1-3 parts of ultra-white polyvinyl alcohol powder, 1-3 parts of polyacrylamide dispersant (polymer), 25-35 parts of red gold titanium dioxide powder 2-7 parts, 2-7 parts of nano barium sulfate, 1-5 parts of sericite.
[0053] In parts by volume, 25-30 parts of styrene-acrylic emulsion, 1-3 parts of transparent lauryl a...
Embodiment 2-6
[0057] Embodiment 2-6 A kind of double-layer film preparation method
[0058] Embodiment 2-6 is respectively a kind of double-layer membrane preparation method, and its preparation method is identical with the double-layer membrane preparation method described in embodiment 1, and the difference is that the specific components of the raw materials that make them are different, specifically as Table 1 shows:
[0059]
Embodiment 7
[0060] Embodiment 7 A Quantum Dot Distribution Photon Illumination System
[0061] This embodiment includes a lighting device mainly displaying the volatility and a scattering plate arranged at the light emitting end of the lighting device mainly displaying the volatility.
[0062] 1. Scattering plate 13
[0063] The scattering plate 13 is a plate body, fixed on the wall, and located on the top of the lighting device that mainly displays the volatility. The diffuser plate 13 is spray-coated with a double-layer film, and the diffuser plate 13 is provided with a bottom layer film 14 and an outer layer film 15 from its surface to the outside. A plurality of holes of 100-112.5nm are opened. The double-layer film is prepared by the preparation method of the double-layer film in Examples 1-6. Of course, if the environment does not allow fixing the diffuser plate 13, low-gray water-based paint or gypsum board can also be used instead, but the light efficiency and diffuser rate wil...
