Problems solved by technology

However, in reality, many projection screens in the form of curtain walls are not in professional projection rooms and theaters, but are mostly in natural light environments for people to appreciate. Projection screens are painted in bright ambient light in various light environments. In the environment, the surface is projected by strong light, which can easily lead to unclear imaging, unevenness, glare, and white fog.
As we all know, if the imaging screen of the projection screen is severely white and foggy, the contrast and brightness of the screen will be greatly reduced, which will easily cause users to see clearly, and then lose their own display, demonstration or advertising effect

Embodiment 1

[0026] A wall coating for projection and a preparation method thereof according to a preferred embodiment of the present invention;

[0027] The wall paint for projection is prepared from the following raw materials in parts by weight:

[0028] 45 parts of polyurethane resin, 5 parts of graphene, 8 parts of nano-titanium dioxide, 22 parts of silica sol, 14 parts of diatomaceous earth, 12 parts of white carbon black, 15 parts of nano-calcium carbonate, 13 parts of talcum powder, 12 parts of attapulgite clay, 5 parts of defoamer, 6 parts of cosolvent, and appropriate amount of water.

[0029] The silica sol is water-dispersible nano-scale silicon oxide with a particle size of 30-50nm and a silicon oxide content of 30-45%. The use of this material can make the coating use nano-scale silica sol as the film-forming substance. The chemical bonds after film formation are mainly Si-O bonds, which are naturally safe and non-toxic. The coating has high hardness, wear resistance and non...

Abstract

The invention discloses a wall-surface paint for projection and a preparation method. The wall-surface paint comprises the following components of: polyurethane resin, graphene, nano titanium dioxide, silica sol, diatomite, white carbon black, nano calcium carbonate, talcum powder, attapulgite clay, defoaming agent, cosolvent and proper amount of water. The preparation method comprises the following steps of: weighing the polyurethane resin and the graphene, adding into a reaction kettle, and reacting to prepare graphene-modified polyurethane resin; then adding the nano titanium dioxide, the silica sol, the attapulgite clay, the defoaming agent, the cosolvent and the proper amount of water, stirring uniformly, and grinding till the particle size is below 20mum; and then adding the diatomite, the white carbon black, the nano calcium carbonate and the talcum powder, and after shearing, obtaining the wall-surface paint for projection. The wall-surface paint disclosed by the invention not only can provide better picture degree and viewing comfort level for projection, but also can provide places for writing and marking of speakers, can be easy for handwriting erasing, and has better application value.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a wall coating for projection and a preparation method thereof. Background technique [0002] Projection screens are widely used in daily life. They are mainly used in large conference rooms, command and control centers, training and education institutions, conference rooms, exhibition halls, station senses, airports, window displays and other occasions. As an indispensable partner of a projector, it takes a lot of money to buy a projection screen, and it needs to be installed by yourself just like the projector. In the past, the main requirements of home projection screens with many applications: picture frame screens, manual screens and Electric screens not only require separate installation and high maintenance costs, but also have space constraints, which have become the main obstacle for projection systems to enter ordinary homes, and the emergence of projection paint has s...
