in the figure: an outer glass layer-1; an intermediate layer-2; PVB film layer-21; a first intermediate glass layer-22; a first SGP film layer-23; a second intermediate glass layer-24; a second SGP film layer-25; inner glass layer-3; a PU film layer-4; transparent PC board-5.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, the utility model provides a lightweight bulletproof glass, and the bulletproof glass mainly comprises an outer glass layer 1, an intermediate layer 2, an inner glass layer 3, a PU film layer 4 and a transparent PC board 5, which are sequentially arranged from a bullet-facing side; wherein:

the inner glass layer 3 and the transparent PC board 5 are bonded and connected through the PU film layer 4.

The intermediate layer 2 specifically includes:

the first middle glass layer 22 is bonded with the outer glass layer 1 through the PVB film layer 21;

a first SGP film layer 23;

a second intermediate glass layer 24, wherein the second intermediate glass layer 24 is adhesively connected with the first intermediate glass layer 22 through the first SGP film layer 23;

second SGP film layer 25, second SGP film layer 25 and first SGP film layer 23 set up respectively in the both sides of glass layer 24 in the middle of the second, and glass layer 24 passes through second SGP film layer 25 adhesive connection with inboard glass layer 3 in the middle of the second.

To sum up:

the PU film layer 4 has a strong toughness property, and thus: after passing through the outer glass layer 1, the intermediate layer 2 and the inner glass layer 3 on the front side of the bullet, most of kinetic energy is absorbed and can be effectively intercepted by the PU film layer 4.

The PVB film layer 21 has good bonding force to the inorganic glass, so that the outer glass layer 1 can still be effectively bonded after being broken, and the falling-off of glass fragments is avoided.

The SGP film layer has the characteristics of high tearing performance and high hardness, and can effectively bond the glass layers on two sides on one hand and effectively increase the resistance of the whole bulletproof glass to bullets on the other hand, so that the bulletproof performance is improved.

The outer glass layer 1, the first intermediate glass layer 22, the second intermediate glass layer 24 and the inner glass layer 3 are all made of high-alumina toughened glass.

Specifically, in one embodiment:

the thickness of the outer glass layer 1 and the thickness of the inner glass layer 3 are both 5 mm;

the thicknesses of the PU film layer 4 and the transparent PC board 5 are respectively 1.25mm and 3 mm;

the thickness of the first intermediate glass layer 22 and the second intermediate glass layer 24 are both 8 mm;

the thickness of the PVB film layer 21 is 1.52 mm;

the thickness of the first SGP film layer 23 and the second SGP film layer 25 are both 1.89 mm.

In conclusion, the thickness of the whole bulletproof glass does not exceed 36mm after the whole bulletproof glass is manufactured and molded, so that the light weight is realized on the premise of meeting the bulletproof requirement.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
