Referring to fig. 1 and fig. 2 together, fig. 1 is a schematic view of a novel high-grade protective transparent member according to an embodiment of the present invention; FIG. 2 is a schematic view of a fragmentation of a unitized shield layer according to an embodiment of the present invention.

As shown, a novel high-grade protective transparency comprises: an outer protective layer 10, the outer protective layer 10 being provided as glass; the unitized protective layer 20 is adhered to the inner side of the outer protective layer 10 through a film, and is provided with a plurality of protective units 40 formed by splicing; the inner buffer layer 30 is adhered to the inner side of the unitized protective layer 20 through a film and is set as a PC board; wherein, the protection unit 40 is made of unitized glass or ceramic, and the end part is filled with a rubber sheet and bonded and hot-pressed.

In one embodiment of the present invention, the novel high-grade protective transparent member is provided with an outer protective layer 10, a unitized protective layer 20, and an inner buffer layer 20 in this order from the outside to the inside. The outer protection layer 10 may be made of high-transmittance and high-strength glass, and the unit protection layer 20 is formed by splicing unit glass or ceramic, i.e., the protection unit 40. The inner buffer layer 30 may be made of polycarbonate or thermosetting polymer, and the layers are laminated by films and finally hot-pressed. Preferably, the film is provided as a polyurethane film, which is widely used.

After all the glass is subjected to cutting, edge grinding and other processes, the unitized protective layer 20 is cut into unitized glass or ceramic through a cutting process, the unitized protective layer is formed by sintering the glass or ceramic, splicing is carried out during laminating, and the side edges are filled with films. The inner buffer layer 30 is made of materials through processes of carving, chamfering and the like, all the materials are laminated through films, and finally the high-grade transparent protection is achieved through a hot pressing process.

In a preferred embodiment, an intermediate reinforcing layer is further disposed between the inner buffer layer 30 and the unitized protective layer 20, the intermediate reinforcing layer is made of glass, and both sides are bonded by a film. The glass is high-transparency and high-strength glass, so that the bulletproof effect of the product can be further improved, the protection after the shooting of multiple bullets is provided, and the driving safety of the palm drivers and passengers is ensured.

In addition, in other embodiments, a polyurethane weight-reducing plate layer is further arranged between the middle reinforcing layer and the inner buffer layer, and two sides of the polyurethane weight-reducing plate layer are bonded through rubber sheets, so that the weight is reduced, the thickness is reduced, and the maneuvering performance of the equipment is improved on the premise of ensuring the light transmission requirement of a product.
