Smoke stone photo-development coating material for preparing film screen and preparation method thereof

Abstract

The invention relates to morion mitsuaki coating layer material used to produce a screen and a preparation method thereof. The morion mitsuaki coating layer material is obtained by processing raw materials, such as silicon carbide, graphite crystal and carbon into micro powder, and then mixing the micro power to be even. During use, the morion mitsuaki coating layer material is added in binder (such as protein gum, soluble resin glue, etc.) to be mixed evenly into liquid; and then the product is evenly applied or coated on a screen base (such as textile, wall, plastics and glass) to form a film, so as to obtain black screen cloth. Projectors, digital projectors and film cine projectors are used as usual and can have the same projecting effect as a TV set. As proven by the practice, the screen produced by the invention has the same projecting effect as a TV set under normal light, can support the projectors, the digital projectors and the film cine projectors to project indoors and outdoors, which greatly widens the scope of the application of projecting, digital and film cine.

Description

technical field [0001] The invention relates to a smoky crystal light-display coating material for making screens and a preparation method thereof. Background technique [0002] With the development of society, projection and digital and film films are gradually popularized and have entered various fields such as schools, enterprises, institutions and families. Currently, projection and digital and film films are projected on white screens or white walls. Its disadvantage is that it must be played under no light or dark conditions, so that the white screen can have a better picture quality. This shortcoming limits where and when projection and digital and film films can be used. For example, movies are played outdoors in rural areas. Because of this restriction, they can only start at night, and farmers are used to going to bed early, so watching movies will affect the work of the next day. Another example is that when a projection is projected indoors, the light must be ...

This shortcoming limits where and when projection and digital and film films can be used

For example, movies are played outdoors in rural areas. Because of this restriction, they can only start at night, and farmers are used to going to bed early, so watching movies will affect the work of the next day.

Another example is that when a projection is projected indoors, the light must be turned off, which will affect the viewer's ability to take notes or refer to other materials
