Abstract
The present invention provides a kind of projection screen preparation aqueous polymer emulsion composition, it is characterised in that includes aqueous polymer emulsion, inorganic nanoparticles and auxiliary agent., can be in arbitrary site using aqueous polymer emulsion composition of the invention, field-applied forms the projection film of high definition and environmental protection on any suitable substrate, without in addition setting screen cloth, is very easy to be projected.Aqueous polymer emulsion composition of the invention can form projection film on the transparent substrates such as glass, for back projection imaging, angle of visibility up to 170 degree, environment resistant light ability it is strong, compared with the prior art, construction is easy, the size of projection screen is not affected by other factors, only determined according to the size of transparent substrate, the environment-friendly type projection screen of formation is influenced very little by ambient light, even if under bright light, beautiful in colour, lifelike image picture can also be formed, and can watch clearly image in the two sides of screen.Due to being back projection imaging, projector can be hidden completely, and demonstrator does not have shade, and projector's light will not generate glare effects, is still the state of substrate in the state of not using, therefore do not influence the original function of substrate.
Description
Technical field
The present invention relates to a kind of projection screen preparation aqueous polymer emulsion composition and its application, in particular to a kind of rings
Guarantor field new material.
Background technique
Currently, optical projection system is widely used in the occasions such as commercial exhibition, multimedia conferencing room, classroom, stadiums, adopted
Projection pattern mainly has positive throwing and rear-projection.Correspondingly, projection screen can also be divided into front projection screen from projection pattern
Curtain (reflective) and back projection screens (transmission-type).The so-called positive installation site for being exactly projector and spectators of throwing is in projection screen
It is ipsilateral, projector issue light project projection screen, form image on the projection screen, then light is re-reflected into people
Eyes.Similarly, so-called rear-projection is exactly that the installation site of projector is located at the two sides of projection screen, projector's hair with spectators
For light out from the side direct projection of projection screen to projection screen, light enters spectators' eyes through projection screen.Front projection screen
It is not limited by size, but need to control environment light can just obtain good viewing effect, it is good in ambient light and illumination
It will cause the degradation of picture contrast under environment.And rear projection screen picture entirety sense is stronger, picture color is gorgeous, and image is forced
Very, and control environment light is not needed, is suitable for ambient light and illuminates good environment, but rear projection screen is dimensionally not so good as
It is positive to throw, and enough back spaces are needed, to ensure projector distance.Also, just throwing and rear-projection can not to be used for simultaneously at present
Screen.
Summary of the invention
The purpose of the present invention is to provide a kind of projection screen preparation aqueous polymer emulsion compositions, it is characterised in that packet
Property of water-bearing polymer emulsion, inorganic nanoparticles and auxiliary agent.

Change copper, nanometer di-iron trioxide, nano-manganese dioxide, one or more kinds of mixtures in nano carbon black, in the composition
Mass content be 0.01-2%.
In the present invention, the auxiliary agent is made of defoaming agent, dispersing agent and film forming agent, mass content in the composition
For 1-10%.
The second aspect of the present invention provides a kind of biplane projection screen, which is characterized in that using above-mentioned waterborne polymeric cream
Liquid composition is coated on substrate and forms projection film, and the use of projection film combination projector forms image.
The third aspect of the present invention provides a kind of aqueous polymer emulsion composition of the present invention and prepares in projection screen
In purposes.
Projection screen preparation of the invention is at low cost, environmentally friendly with aqueous polymer emulsion composition and construction is easy, and adopts
, can be coated and dried at normal temperatures and pressures with modes such as conventional spraying, roller coating, organic solvent taste is not generated, to environment without dirt
Dye, rate of drying is fast at normal temperatures and pressures, and construction is easy, therefore can be made, and further reduced the cost of projection screen,
Feature is that the coating of aqueous polymer emulsion composition coating material is not necessarily to the professional training of professional, sharp at normal temperatures and pressures
It is coated directly on required cleaning substrate with simple spraying or method of roll coating, spontaneously dries film forming.
It, can be existing on any suitable substrate in arbitrary site using aqueous polymer emulsion composition of the invention
The projection film that field coating forms high definition and environmental protection is very easy to be projected it is not necessary that screen cloth is in addition arranged.Of the invention is aqueous
Polymeric emulsion composition can form projection film on the transparent substrates such as glass, be used for back projection imaging, angle of visibility up to 170 degree,
Environment resistant light ability is strong, and compared with the prior art, construction is easy, the size of projection screen is not affected by other factors, basis
The size of transparent substrate is determined, and the environment-friendly type projection screen of formation influenced very little by ambient light, even if under bright light,
Beautiful in colour, lifelike image picture can also be formed, and can watch clearly image in the two sides of screen.Work as room
When the glass or substrate of interior window prepare projection film as the above-mentioned waterborne polymeric mixture of substrate painting, indoor and outdoor can see throwing
Shadow imaging, and influence of the projection film to indoor shading value is smaller when not projecting.Projection membrane removal is easier to, and is held after being steeped with clear water
Easy-clear does not stay the trace of film.
Aqueous polymer emulsion composition of the invention can also be coated in existing non-woven fabrics, white curtain or wall
On, the projection film of high definition and environmental protection is formed, which overcomes even if that can also form clearly picture under bright light
Existing white curtain needs the shortcomings that using in the dark.Environment-friendly type projection screen of the invention can be used for outdoor advertising, room
In internal and external ornament finishing, display and demonstration, office realm etc..
