Anti-sniper rifle bullet composite glass

Abstract

The invention relates to composition glass capable of preventing a sniper rifle bullet, which can be used for preventing smashing and can resist sniper rifle bullet attack. A transparent PC (Poly Carbonate) plate is arranged between two pieces of floating-process glass; two PU (Poly Urethane) films are arranged between the floating-process glass and the transparent PC plate; the two pieces of floating-process glass, the transparent PC (Poly Carbonate) plate, and the two PU films are bonded together by heating and pressurizing to form an anti-smashing transparent composite plate with a smashing prevention performance; a plane parallel overlapped composite structure is arranged between the anti-smashing transparent composite plate and F79 type bullet-proof composite glass; a cavity structure is formed between the anti-smashing transparent composite plate and F79 type bullet-proof glass; the cavity is internally provided with a molecular sieve, a molecular sieve framework and a silicone sealant in sequence from inside to outside; the disadvantages of the prevention capability of the F79 type bullet-proof glass are made up and the complementation between the cavity and the F79 type bullet-proof composite glass is formed; and a whole protection system of a solid transparent protection screen is completed and a barrier which cannot be passed by improper invasion of a person adopting a common mechanical manual tool is formed, so that safe and effective protection guarantees are provided for antiriot terrorist attacks.

Description

technical field [0001] The invention relates to a bulletproof composite glass, in particular to a kind of anti-sniper rifle bullet composite glass which can resist smashing and attack by sniper rifle bullets. Background technique [0002] The traditional processing technology of bulletproof composite glass generally uses intermediate layer materials such as PVB to be sandwiched between three to four layers of glass, and is formed by high temperature and high pressure. Its defense ability can only reach the anti-79 type 7.62mm light submachine gun bullet. At present, the glass used for counters in financial business places is within this level of protection. It is still insufficient in preventing violent terrorist attacks and critical places. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art and provide a bulletproof composite glass capable of preventing sniper rifle bullets, which is used to improve the...
