Problems solved by technology

The common defect of glass bead curtain is that it is afraid of moisture and easy to drop beads
In contrast, the metal screen has no defects of powder falling or moisture resistance because the metal powder is mixed with resin and applied on the screen blank, and the brightness gain is high, but the cost of the metal screen is higher

Abstract

The invention discloses a novel projection curtain coating. The novel projection curtain coating comprises PVC paste resin 100parts, silvering glass powder 1-8parts, anatase titanium dioxide 8-15parts, plasticizer 65-85parts, heat stabilizer 2-10parts, wetting agent 0-1parts and dispersant 0-1parts by weight. According to the novel projection curtain coating, the silvering glass powder is added as a filler of the projection curtain coating, the silvering glass powder and PVC have good binding property, so light weight and no-easy shedding can be realized, the silvering glass powder has the better gain effect and better brightness compared with traditional metal powder or glass powder, and the silvering glass powder is a projection curtain manufacturing material suitable for household and theater use.

Description

technical field [0001] The invention relates to a novel projection screen coating. Background technique [0002] At present, most projection screens used for film or video image projection are formed by superimposing a black base plate and a white polyvinyl chloride (PVC) thin layer. Traditional projection screens have low reflectivity (gain) parameters, resulting in dark projection images that need to be seen clearly in a dark space; and traditional projection screens have poor scattering capabilities, and projection images can only be seen in a dark space. Can only be seen from a small viewing angle. [0003] In order to improve the projection effect of the projection screen, people have proposed a glass bead screen with glass beads glued on the PVC film and a metal screen with a metal powder layer added on the curtain blank. The common defect of glass bead curtain is that it is afraid of moisture and easy to drop beads. In contrast, the metal screen has no defects of p...
