Abstract
This application discloses a kind of white modeling projection screen, including PET sheet, it is formed at the PET transfer black layer of PET sheet one side and is formed at the PET matt white of PET sheet another side, PET matts white is included by quality accounting：53% polyethylene terephthalate；18% anatase thpe white powder；23% plasticizer；2.5% heat stabilizer；The 0.7% white colouring agent of matt；0.3% barium sulfate；1.2% aluminium powder；Surplus is wetting agent.The screen of this case can be good at taking into account the projection of 2D films, while ensure high-contrast, perfect color rendition.
Description
Technical field
The application is related to a kind of seehears, more particularly to a kind of white modeling projection screen.
Background technology
At present, the screen for projecting has white plastic curtain, glass bead screen, metal curtain.White plastic curtain is a kind of both economical screen,
It has the characteristics of rollable, diffusing reflection, big field of view angle.But its brightness is not so good as glass bead screen, glass bead screen overcomes lacking for white plastic curtain
Point, daytime imaging clearly.But glass bead screen requires higher to real-world environment, can not effectively obstruct steam, reduce glass bead screen
Using effect, improve projector equipment power consumption.
The content of the invention
It is an object of the invention to provide a kind of white modeling projection screen, to overcome deficiency of the prior art.
To achieve the above object, the present invention provides following technical scheme：
The embodiment of the present application discloses a kind of white modeling projection screen, including PET sheet, the PET that is formed at PET sheet one side turn
Move black layer and be formed at the PET matt white of PET sheet another side, PET matts white is included by quality accounting：
53% polyethylene terephthalate；
18% anatase thpe white powder；
23% plasticizer；
2.5% heat stabilizer；
The 0.7% white colouring agent of matt；
0.3% barium sulfate；
1.2% aluminium powder；
Surplus is wetting agent.
Preferably, in above-mentioned white modeling projection screen, the PET matts white surface is covered with barrier layer to obstruct sky
Steam in gas.
Preferably, in above-mentioned white modeling projection screen, the thickness of the barrier layer is 10 μm.
Preferably, in above-mentioned white modeling projection screen, the PET matts white is formed at using electrostatic adsorption type spraying
PET sheet surface.
Preferably, in above-mentioned white modeling projection screen, electrostatic adsorption type spraying preferably uses platform-type spraying.
Preferably, in above-mentioned white modeling projection screen, constant temperature and humidity is kept in electrostatic adsorption type spraying process.
Preferably, in above-mentioned white modeling projection screen, the plasticizer is hexanedioic acid dioctyl ester.
Preferably, in above-mentioned white modeling projection screen, the heat stabilizer is epoxidized soybean oil.
Compared with prior art, the advantage of the invention is that：The screen of this case can be good at taking into account the projection of 2D films,
Ensure high-contrast, perfect color rendition simultaneously.
Brief description of the drawings
, below will be to embodiment or existing in order to illustrate more clearly of the embodiment of the present application or technical scheme of the prior art
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments described in application, for those of ordinary skill in the art, on the premise of not paying creative work,
Other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 show in the specific embodiment of the invention structural representation of modeling projection screen in vain；
Fig. 2 show in the specific embodiment of the invention white modeling projection screen angle of scattering schematic diagram；
Fig. 3 show in the specific embodiment of the invention white modeling projection screen gain curve figure；
Fig. 4 show in the specific embodiment of the invention white modeling projection screen acoustic efficiency curve map.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, detailed retouch is carried out to the technical scheme in the embodiment of the present invention
State, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Based on the present invention
In embodiment, the every other implementation that those of ordinary skill in the art are obtained on the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
With reference to shown in Fig. 1, projection screen, including PET sheet 1, the PET transfer black layer for being formed at PET sheet one side are moulded in vain
2 and it is formed at the PET matts white 3 of the another side of PET sheet 1.
Further, the surface of PET matts white 3 covered with barrier layer 4 to obstruct the steam in air.
Further, the thickness of the barrier layer is 10 μm.
PET matts white 3 is formed at PET sheet surface using electrostatic adsorption type spraying, and PET matts white 3 is accounted for by quality
Than including：
53% polyethylene terephthalate；
18% anatase thpe white powder；
23% plasticizer；
2.5% heat stabilizer；
The 0.7% white colouring agent of matt；
0.3% barium sulfate；
1.2% aluminium powder；
Surplus is wetting agent.
Wherein, plasticizer is hexanedioic acid dioctyl ester.Heat stabilizer is epoxidized soybean oil.
In the technical scheme, sprayed using Electrostatic Absorption, allow paint particles first to turn to take negative electrical charge at a high speed, in attractive interaction
It is adsorbed onto under effect in screen, the film of formation uniformly enriches, adhesive force is strong, wearability is good.
Electrostatic adsorption type spraying, can be more preferably empty using limited screen production preferably using platform-type spraying (level spray)
Between.
Further, constant temperature and humidity is kept in spraying process.
The gain of the screen reaches 3.0, and its visual angle, gain effect and acoustic efficiency are joined shown in Fig. 2 to 4 respectively.
The screen of this case can be good at taking into account the projection of 2D films, while ensure high-contrast, perfect color rendition.
It should be noted that term " comprising ", "comprising" or its any other variant are intended to the bag of nonexcludability
Contain, so that process, method, article or equipment including a series of elements not only include those key elements, but also including
The other element being not expressly set out, or also include for this process, method, article or the intrinsic key element of equipment.
In the absence of more restrictions, the key element limited by sentence "including a ...", it is not excluded that including the key element
Process, method, other identical element also be present in article or equipment.
Described above is only the embodiment of the application, it is noted that for the ordinary skill people of the art
For member, on the premise of the application principle is not departed from, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as the protection domain of the application.
