Material for preparing projection screen

Abstract

The invention relates to a material for preparing a projection screen. The material comprises the following components in parts by weight: 60-70 parts of polycarbonate, 1-5 parts of acrylic resin, 25-30 parts of organosilicone, 1-1.5 parts of solvent red, 3-4 parts of carbon black, 2-3 parts of phthalocyanine blue, 1-1.5 parts of a dispersing agent and 2-3 parts of an antioxidant. A projection screen plate prepared from the material has no splicing seam (seamless visually and structurally); the size of the screen can be set at will; splicing is not needed; the projection screen is high in resolution, projection color rendition degree and close-range viewing definition, low in grey, high in light and free of blue light, is not dazzling, and overcomes the problem that a projection curtain ispoor in resolution. Due to the fact that the projection screen can be curled, the projection screen has the advantages of easiness in transportation and installation, convenience in production and machining and long in service life.

Description

technical field

[0001] The invention relates to the field of projection screens, in particular to a material for preparing projection screens. Background technique

[0002] A 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, it is better to choose a screen with a wide viewing angle and low gain when there are many people watching or viewing in a horizontal direction. The screen helps to improve the contrast of the screen, increase the gray scale of the image, make the color vivid, and increase the visibility of the image.

[0004] At present, the large screen of the projection screen is a splicing of small screens, and the physical gap between each screen is large when splicing. Since the traditional projection screen cannot be curled, it occupies a large area during transportation and is inconvenient t...
