Description
Technical Field
The invention relates to the field of holographic recording materials, in particular to a packaging body of a photopolymer holographic recording material and a packaging method thereof.
Background
The head-up display (HUD) is a flying auxiliary instrument commonly used in an airplane, and can integrally display various flying information provided by an instrument panel of the airplane on the head-up display in the form of images and characters, and meanwhile, the head-up display is overlapped with a real scene outside the airplane, so that a pilot can conveniently view various flying data at any time almost without changing the focal length of eyes. Currently, head-up displays are rapidly developed and are gradually being equipped in consumer devices such as automobiles.
The performance of conventional head-up displays is limited primarily by two aspects: firstly, the instantaneous field of view of the system is always smaller than the total field of view, and simultaneously the total field of view is also smaller than the expected field of view; secondly, the utilization rate of light energy is low, and the display brightness is lower. The holographic head-up display can optimize two parameters, and can optimize luminosity performances such as display brightness, external transmittance and the like while expanding a view field.
Early holographic head-up displays mostly used dichromated gelatin media, but the recording material of the holographic head-up display should have high environmental stability, be heat-resistant, light-resistant, high-pressure-resistant, and moisture-proof, while maintaining the holographic properties. The photopolymer is a holographic recording material with more excellent performance, and has the characteristics of high diffraction efficiency, high sensitivity, high resolution, high signal-to-noise ratio, low cost, simple process and the like. Although photopolymer holographic recording materials have many advantages, most photopolymer holographic recording materials have poor scratch resistance if not packaged, and are exposed in air, which affects the aging resistance and results in reduced holographic performance.

An encapsulation body of a photopolymer holographic recording material, wherein an antistatic agent is added to one or more of a latex layer, a support and an auxiliary layer.
A packaging method of a photopolymer holographic recording material packaging body comprises the following steps:
① filtering the mixed solution with a filter with a pore size of 0.1-0.45 μm in a dark room of an ultraclean laboratory to obtain a filtrate, degassing the filtrate under reduced pressure in a vessel which can be evacuated, injecting inert gas nitrogen into the filtrate in the vessel, and removing oxygen and bubbles in the filtrate to obtain the photopolymer emulsion;
② in vacuum working chamber or container filled with inert gas nitrogen (such as glove box), coating appropriate amount of photopolymer emulsion uniformly on the clean support, and then covering with protective layer;
③ in a vacuum working chamber or a container (such as a glove box) filled with inert gas nitrogen, the temperature of the pressure plate above the protective layer is kept at 80-90 ℃, and meanwhile, the pressure of 0.2-1.2 MPa is applied to the two sides for 0.5-1 min;
④ drying the photopolymer encapsulation body for 36-48 h in a vacuum working chamber or a container (such as a glove box) filled with inert gas nitrogen, taking out and trimming the edge to obtain the encapsulated photopolymer holographic recording material, namely the photopolymer holographic recording material encapsulation body.

The prepared photopolymer holographic recording material packaging body has strong weather resistance and small influence of environmental factors, and the recorded hologram can be kept stable for a long time.
