Abstract
The utility model relates to the technical field of projection, especially to a projection screen. The projection screen comprises a fabric layer, a polyurethane coating is arranged on the fabric layer and plated with an aluminized layer, and the aluminized layer is coated with a protective layer. The projection screen provided by the utility model can provide good image effect as a hard screen, and is also foldable and portable, wherein use and accommodation of the projection screen are both relatively convenient; the brightness gain of the screen can be conveniently adjusted by adjusting the paint formula of the polyurethane coating, so that the projection screen can be further divided into a projector screen and a film screen; and the protective layer protects the vacuum aluminized layer which is not resistant to scratches, thereby prolonging the service life of the projection screen.
Description
Technical field
The utility model relates to shadow casting technique field, relates in particular to a kind of projection screen.
Background technology
At present, though be portable small-business demonstration, multimedia conferencing chamber, classroom, stadiums, church, commercial location, large-scale auditorium, virtual demonstration even the jumbotron of great Dao cinema all adopt shadow casting technique.Briefly, the ray cast that Shi Jiang projector of shadow casting technique sends, to projection screen, forms image on projection screen, and then light reflexes to eye again.If the collocation of projection screen and projector is proper, can obtain the drop shadow effect of high-quality.
Projection screen generally can be divided into reflective, transmission-type two classes function; Reflective for just throwing, transmission-type is for rear-projection; Just throw curtain and be divided into again plane curtain, camber curtain; Quality, can be divided into glass curtain, metal curtain, embossing plastics curtain etc.Generally speaking, the picture effect of hard curtain is better than soft curtain.But existing hard curtain, because quality is harder, can not fold conventionally, in movement or carrying process, need to take larger space, but also be easy to damage.
Utility model content
The purpose of this utility model is to provide a kind of projection screen, and being intended to solve existing hard projection screen can not fold, and moves or carries inconvenience and hold flimsy technical matters.
The utility model is achieved in that a kind of projection screen, comprises tissue layer, and described tissue layer is provided with polyurethane coating, on described polyurethane coating, is coated with aluminium coated, on described aluminium coated, is coated with protective seam.
As a kind of improvement, the thickness of described polyurethane coating is 25～45 μ m.
As a kind of improvement, the thickness of described aluminium coated is 30～50nm.
As a kind of improvement, the thickness of described protective seam is 10～20 μ m.
As improving further, described aluminium coated is vacuum aluminium coated layer.
As improving further, described protective seam is organic silicon face stopping off.
Owing to adopting technique scheme, the beneficial effects of the utility model are:
Because tissue layer is as base material, polyurethane coating is arranged in tissue layer, set up one deck continuously smooth, there is filming of some strength, the gap of sealing tissue layer, simultaneously for the follow-up processing of aluminizing provides one to accept layer, be convenient to carry out vacuum aluminum-coated processing, and by adjusting polyurethane coating formulation for coating material used, adjust easily the luminance gain of curtain, and then can be subdivided into projector curtain use and the use of film curtain, vacuum aluminium coated layer is set, make projection screen that hard curtain good picture effect like that can be provided, can realize again folding portable, use, place all more convenient, on vacuum aluminium coated layer, be coated with organic silicon face stopping off, protect the not vacuum aluminium coated layer of damage resistant, vacuum aluminium coated layer is played a protective role, prevent that on vacuum aluminium coated layer, producing cut etc. affects result of use, extended the serviceable life of projection screen.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Wherein: 1-tissue layer, 2-polyurethane coating, 3-aluminium coated, 4-protective seam.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of projection screen, comprise tissue layer 1, using tissue layer 1 as base material, tissue layer 1 is provided with polyurethane coating 2, set up one deck continuously smooth, there is filming of some strength, the gap of sealing tissue layer 1, simultaneously for the follow-up processing of aluminizing provides one to accept layer, be convenient to carry out vacuum aluminum-coated processing, and by adjusting polyurethane coating 2 formulation for coating material used, polyurethane coating 2 is preferably waterborne polyurethane resin coating, adjust easily the luminance gain of projection screen, and then can be subdivided into projector curtain use and the use of film curtain, on polyurethane coating 2, be coated with aluminium coated 3, make projection screen that hard curtain good picture effect like that can be provided, can realize again folding portable, use, place all more convenient, on aluminium coated 3, be coated with protective seam 4, protect the not aluminium coated 3 of damage resistant, prevent that on aluminium coated 3, producing cut etc. affects result of use, extended the serviceable life of projection screen.
As specific embodiment of the utility model, in tissue layer 1, adopt plate gravure coating method coating polyurethane coating 2, on polyurethane coating 2, adopt vacuum aluminum-coated mode to be coated with vacuum aluminium coated layer, on vacuum aluminium coated layer, be coated with organic silicon face stopping off, specifically can select as required suitable silicone resin coating protective seam, can certainly select as required other organic silicon face stopping off, owing to having adopted the mode of intaglio plate coating and vacuum aluminum-coated method, make projection screen, can make good homogeneity, can guarantee that spectators are in level, when vertical direction is watched from all angles, picture can not produce colour cast.
In the present embodiment, the thickness of polyurethane coating 2 is 25～45 μ m, and the thickness of vacuum aluminium coated layer is 30～50nm, and the thickness of organic silicon face stopping off is 10～20 μ m.
The projection screen that the utility model provides, comprise tissue layer 1, tissue layer 1 is provided with polyurethane coating 2, on polyurethane coating 2, be coated with aluminium coated 3, on aluminium coated 3, be coated with protective seam 4, by adjusting polyurethane coating 2 formulation for coating material used, adjust easily the luminance gain of projection screen, and then can be subdivided into projector curtain use and the use of film curtain, make projection screen that hard curtain good picture effect like that can be provided, can realize again folding portable, use, place all more convenient, protective seam 4 is protected the not vacuum aluminium coated layer of damage resistant, extended the serviceable life of projection screen.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
