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 projection screen coating with a porcelain light effect. The coating comprises, by weight, 100 parts of polyvinyl chloride paste resin, 1-10 parts of ceramic powder, 10-15 parts of anatase titanium dioxide, 70-85 parts of a plasticizer and 6-14 parts of a heat stabilizer. The ceramic powder is added as a filler of the projection screen coating, and makes a projection screen have a good surface effect, porcelain light generated by the ceramic powder makes the screen have good bright gain, the cost of the screen in the invention is substantially lower than that of metal screens, and the gain effect of the projection screen is substantially better than that of glass screens.

Description

technical field [0001] The invention relates to a projection screen coating with porcelain light effect. 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, which 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. It 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 screen blank. The common defect of glass bead curtain is that it is afraid of moisture and easy to drop beads. In contrast, the metal ...
