Abstract

The invention relates to the technical field of optical projection, in particular to an anti-glare reflective projection screen. The projection screen is a beaded screen; an anti-glare coating is arranged outside a beaded coating of the projection screen; the paint of the anti-glare coating comprises the following ingredients: an organic solvent, polyethylene glycol terephthalate, nano titanium dioxide, modified nano silver, acrylic resin, isocyanate, ethyl acetate, an infrared absorbent, an ultraviolet absorbent and an antistatic assistant. The organic solvent is a mixed solvent of propyleneglycol monomethyl ether and n-butyl alcohol; the ultraviolet absorbent is benzotriazole; the infrared absorbent is nano indium oxide or nano tin oxide; and the antistatic assistant is an ethylamine antistatic assistant or a quaternary amine antistatic assistant. The curtain screen has a good reflective effect, higher in projection brightness, can effectively lower a glaring degree of projection light and avoids visual fatigue.

Description

Technical field [0001] The invention relates to the technical field of optical projection, in particular to an anti-glare reflective projection screen. Background technique [0002] The projection screen is one of the most commonly used products in the peripheral equipment of the projector. When the projector is working, the light projected by the projector is reflected on the projection screen and enters the human eye. People can see the picture projected by the projector on the projection screen. . In order to improve the display effect of the projection screen, the surface of the screen will be coated with various coatings. Some of these coatings are to improve the brightness of the reflected light, and some are to enhance the reflection effect. In short, the coating on the projection screen can significantly improve the projection. The display effect of the curtain. [0003] Among them, many projection screens are coated with glass bead paint on the surface of the screen in o...
