Description

technical field

[0001] The invention relates to the technical field of paints, in particular to a screen paint formula for rear projection and a spraying method thereof. Background technique

[0002] In order to reflect the interaction and immersion in the existing interactive experience projects and appearance products, more and more places use the technology of rear projection display. On the one hand, it prevents the viewer from blocking the projection light from the front; on the other hand, the viewer cannot see the projector and the light, and the sense of immersion is stronger.

[0003] Most of the components of the existing screen paint are mainly composed of silvery white metal aluminum and thinner. When the existing screen paint is used for rear projection, the light transmission is poor, the projection effect is not clear, and the adhesion of the screen paint is low. Not suitable for spraying on clear plastic panels.

[0004] Therefore, the prior art still needs...
