A kind of preparation method of projection screen plate

Abstract

The invention relates to a preparation method of a projection screen panel, which comprises the following steps: 1) uniformly mixing polycarbonate, acrylic resin and organic silicon, drying for 6 hours, and stirring at a high speed to obtain a polymer raw material; 2) taking solvent red and charcoal Black, phthalocyanine blue, dispersant, antioxidant, polycarbonate, stirred at low speed, heated to 260-280°C, granulated to obtain colored nanoparticles; 3) Take the polymer raw materials and steps described in step 1) 2) Stir the colored nanoparticles, add them into the extruder, and extrude to obtain a transmissive screen plate with a thickness of 1.5-2 mm. The projection screen panel prepared by the method of the present invention can achieve physical seamlessness, the size of the screen can be set arbitrarily, and splicing is not required, the projection screen has strong resolution, high degree of projection color reproduction, high definition when viewed at close range, low gray and high light , no blue light, no glare, which solves the problem of poor resolution of the projection screen.

Description

technical field [0001] The invention relates to the field of projection screens, in particular to a preparation method of a projection screen plate. Background technique [0002] Projection screen is a tool used to display images and video files in movies, offices, home theaters, large conferences, etc. [0003] The selection of projection screens in different spaces is also different. For example, when there are a large number of people watching or when viewing horizontally, a screen with a wide viewing angle and low gain should be selected. For viewing in a narrow and long space, a screen with a narrow viewing angle and high gain should be selected, and a screen with appropriate gain should be selected. The screen helps to improve the contrast of the screen, so that the grayscale of the image is increased, the color is bright, and the observability of the image is increased. [0004] At present, the large screen of the projection screen is a splicing of small screens, and...

AI Technical Summary

Problems solved by technology

Since the traditional projection screen cannot be curled, it occupies a large area during transportation and is inconvenient to transport

Due to the physical defects of the screen cloth, the projection screen has poor resolution and low projection color reproduction, and the projection screen has poor brightness effect and large light pollution. The brightness coefficient of the reflective screen can only reach 0.36, so it can only be used for front projection and cannot be used for rear projection. , the composite coating is not easy to clean and not durable
