Abstract

The invention discloses a grey micro-bead projection screen which comprises a base material, a PVC black layer formed on one side of the base material and a functional film formed on the other side of the base material, wherein the functional film comprises a light absorption layer and micro-beads protruding out of the upper surface of the light absorption layer, and the functional film comprises, by mass, polystyrene 76%, matte grey coloring agent 2.5%, fire retardant 3%, bridging agent 6.2%, stabilizing agent 1%, defoaming agent 2.3%, wetting agent 3% and the balance micro-beads. The invention further discloses a manufacturing method of the grey micro-bead projection screen. The brightness of the projection screen is high, the gain is improved by more than 2.8 times, an effective scattering angle is larger than 32 degrees, and the grey micro-bead projection screen has the advantages of being high in definition and good in color reproduction and is a special screen for a home theater. Especially, the contrast ratio and black-grey contrast ratio can be well improved under the condition that the brightness is improved, and the perfect stainless frame effect is ensured. The screen surface has the advantages of being anti-corrosion, moisture-proof and flame-retarding, reducing longtime brightness decay and the like.

Description

technical field [0001] The present application belongs to the field of projection, and in particular relates to a gray bead 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 proj...
