Problems solved by technology

As a result, when displaying images, dense crystal points appear on the surface of the screen, especially when displaying white
Moreover, due to the width-to-narrow ratio of the hemisphere on the surface of the AG film, it also causes severe reflection on the screen.
[0003] In addition, the current laser anti-light screen still has the problem of poor anti-light effect. In the case of bright ambient light, the screen display effect is not clear, and it is in a foggy state.

Embodiment

[0025] This embodiment will provide the preparation method of the AG film layer.

[0026] Pour the UV hardening solution into the mixer, add silica sanding agent with a particle size of 5 μm, methyl amyl alcohol dispersant, and black nano-color paste. The dosages of the sanding agent, dispersant, and black nano-color paste are respectively 5% to 8%, 0.5% to 1%, and 6% to 9% of the weight. Add ethyl acetate or industrial toluene to dilute to a solid content of 24% to 26%, and stir with a high-speed disperser while vacuuming. The mixture obtained by stirring is pressurized by an air compressor at 0.3mpa to 0.4mpa and poured into the coating trough, and a layer of 20um thick wet glue is evenly coated on the surface of the 125μm thick PET optical precoating film with a micro concave coating equipment. The temperature is divided into 40 degrees, 60 degrees, 80 degrees, 100 degrees, and 120 degrees to dry the solvent out of the oven, and then use ultraviolet light with a wavelength...

Abstract

The invention discloses an anti-light-interference AG film composition for a laser anti-light screen and a preparation method of an AG film. The anti-light-interference AG film composition comprises UV hardening liquid, a sanding agent, a dispersing agent and black nano color paste, wherein the dosages of the sand finishing agent, the dispersing agent and the black nano color paste are respectively 5-8%, 0.5-1% and 6-9% of the weight of the UV hardening liquid. The AG film provided by the invention has relatively high haze, can be used as the outermost layer of a laser anti-light screen, and is used for improving the incidence rate of light rays of a projector and reducing the reflectivity of the light rays of the projector, so that the imaging effect is improved; the AG film is high in hardness, so that the screen can be prevented from being scratched; the surface color of the AG film is transparent black, the anti-interference light function of the screen can be improved through black light absorption, and images displayed on the screen are still clear even under the condition that ambient light is strong.

Description

technical field [0001] The invention belongs to the technical field of optical display, and in particular relates to an anti-jamming light AG film composition used for laser anti-light screens and a preparation method of the AG film. Background technique [0002] AG film is generally used as the outermost layer of the laser anti-light screen to protect the laser anti-light screen and increase the incident rate of projector light. At present, the AG film is obtained by UV imprinting. When observing the surface of the AG film under a microscope, it can be seen that the surface structure is a regular hemisphere next to each other. As a result, when displaying images, dense crystal points appear on the surface of the screen, especially when displaying white. Moreover, due to the aspect ratio of the hemisphere on the surface of the AG film, the screen is seriously reflective. [0003] In addition, the current anti-light laser screen still has the problem of poor anti-light effe...
