Manufacturing method of projection screen panel

Abstract

The invention relates to a manufacturing method of a projection screen panel. The manufacturing method of the projection screen panel comprises the following steps that (1) polycarbonate, acrylic resin and organic silicon are uniformly mixed, dried for six hours and stirred at the high speed, so that a macromolecule raw material is obtained; (2) solvent red, carbon black, phthalo blue, a dispersing agent, an antioxidant and polycarbonate are taken and stirred at the low speed, the heating is conducted to enable the temperature to range from 260 DEG C to 280 DEG C, and pelletization is conducted, so that colored nano particles are obtained; and (3) the macromolecule raw material obtained in the step (1) and the colored nano particles obtained in the step (2) are taken, stirred and added toan extruder set, and the transmission screen panel is obtained through extrusion, specifically, the thickness of the transmission screen panel ranges from 1.5mm to 2mm. The projection screen panel which is manufactured according to the manufacturing method of the projection screen panel can achieve the physical seamless purpose, the size of a screen can be set at random, the screen does not need to be spliced, and the projection screen is high in resolution, high in projection color rendition degree, high in close-range watching definition, low in grey degree and high in light degree, is freeof blue light, is not dazzling and solves the problem that the resolution of the projection screen is poor.

Description

technical field [0001] The invention relates to the field of projection screens, in particular to a method for preparing a projection screen plate. 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 inconveni...

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
