Splinter proof glass

Abstract

The invention discloses a bulletproof glass which comprises at least three layers of glass basic level. A layer of transparent plastic membrane is arranged between the adjacent two layers of glass basic level; at least one layer of a plurality of glass basic levels is a dimming glass layer which consists of two layers of ITO glass and polymer dispersion liquid crystal materials that are solidified between the two layers of the ITO glass. According to the technical proposal, the dimming glass layer is added on the basis of the present bulletproof glass; therefore the bulletproof glass is opaque in normal state and is transparent under a certain external voltage effect, thus, the transparent state and the opaque state can be switched quickly. When meeting attacks, the bulletproof glass can be switched to be the opaque state quickly to block out lines of sight of raiders, which leads the raiders not to aim at targets, thus protecting the life and property security of users effectively.

Description

a bulletproof glass technical field The invention belongs to the field of glass processing and manufacturing, and in particular relates to a bulletproof glass capable of adjusting light. Background technique Bulletproof glass is a kind of high-tech glass developed in recent years. It is generally recognized by users because of its high strength enough to resist the penetration of bullets of the corresponding level. But the fly in the ointment is that if it encounters bullets with a higher bulletproof level than its own, or multiple bullets at the same position, the bulletproof glass will inevitably be broken down, and the existing bulletproof glass is transparent at any time. The attacker can completely see the situation of the target inside from the outside, and carry out targeted attacks, and the target cannot effectively avoid it, thus threatening the safety of the user's life and property. Contents of the invention In order to solve the above-mentioned technical pr...
