Abstract
The invention provides a screen paint formula for rear projection and a spraying method thereof, wherein the screen paint formula includes an NC primer and an NC top coat, and in terms of mass ratio, the NC primer includes 5-15 parts of flat white NC paint And 10-20 parts of NC lacquer thinner, described NC finish paint comprises 5-15 parts of semi-matte NC lacquer, 1-3 parts of silver white pearlescent powder and 10-20 parts of NC lacquer thinner. The primer in the screen paint formula for rear projection of the present invention has selected plain white NC paint for use, which meets the requirements of sufficient adhesion and certain light transmittance for the primer, and the top paint has selected semi-matt NC paint and silver white pearlescent powder, The semi-matte NC paint is a transparent paint, does not reflect light, and has no influence on imaging, while the silver-white pearl powder has the same imaging effect as the metal screen powder in the existing screen paint. The screen paint formula of the present invention is used for the back side of the screen When projecting, the light transmission is good and the projection effect is good.
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...
