Abstract

The invention discloses a gray microbead projection screen and a preparation method thereof; the gray microbead projection screen comprises the following components: a base material referring to a poly (ethylene 2, 6-naphthalate) and PET(polyethylene terephthalate) copolyester; a PVC black layer arranged on one side of the base material; a function film arranged on the other side of the base material, wherein the function film comprises a luminous absorption layer and microbeads extruding on the top surface of the luminous absorption layer; the function film comprises the following ingredientsby mass ratio: 75% polystyrene, 3% yogon gray coloring agent, 2.5% fire retardant, 6% bridging agent, 1% stabilizing agent, 2.3% antifoaming agent, 3% wetting agent, 0.5% thickening agent, 0.5% levelling agent and balance microbeads. The gray microbead projection screen is high in brightness and resolution, and excellent in color reductibility.

Description

technical field [0001] The invention relates to the technical field of projection screens, in particular to a gray bead projection screen and a preparation method thereof. Background technique [0002] At present, projection technology is used in small mobile business presentations, multimedia conference rooms, classrooms, stadiums, churches, commercial places, large auditoriums, virtual displays and even super-large screens as large as movie theaters. Simply put, projection technology is to project the light from the projector onto the projection screen, form an image on the projection screen, and then reflect the light to the human eye. If the projection screen is properly matched with the projector, high-quality projection effects can be obtained. [0003] Projection screens can be generally divided into reflective and transmissive types in terms of function; reflective type is used for front projection, and transmissive type is used for rear projection; front projection...
