Abstract

The invention discloses a matte plastic projection screen. The matte plastic projection screen comprises a base material formed on a PET black layer on one face of the base material, a PET matte white layer on the other face of the base material, and a functional film formed on the surface of the PET matte white layer, wherein the functional film comprises, by mass, polyvinyl chloride 75%, fire retardant 8%, bridging agent 5.6%, stabilizer 3.5%, defoaming agent 4% and wetting agent 3.9%. The invention further discloses a manufacturing method of the matte plastic projection screen. The brightness gain of the matte plastic projection screen is improved by 0.92 time, an effective scattering angle is larger than 160 degrees, and the matte plastic projection screen has the advantages of being high in definition, good in color reproduction and good in visual effect. The screen surface physical parameter stabilization attenuation is reduced, a green and environment-friendly screen face material is free of odor, and the screen surface flatness is good.

Description

technical field [0001] The application belongs to the field of projection, and in particular relates to a white plastic projection screen and a manufacturing 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 projecti...
