Light high-permeability bulletproof anti-smashing glass

Abstract

The invention relates to the technical field of glass, and in particular relates to light high-permeability bulletproof anti-smashing glass, which comprises a high-permeability layer and a bulletproofglass layer which are arranged in parallel, a gap is left between the high-permeability layer and the bulletproof glass layer, a sealing elastomer is fixedly arranged at the edge inside the gap, thesealing elastomer forms a hollow chamber together with the high-permeability layer and the bulletproof glass layer, fixing clamps are arranged at the top and the bottom of the high-permeability layerand the bulletproof glass layer, a plurality of first ventilation holes are arranged on the high-permeability layer, and a plurality of second ventilation holes are arranged on the bulletproof glass layer. The invention has the beneficial effects that the integral integrity of the bulletproof glass can be maintained after the outer layer glass is impacted and cracked, the integral strength of thebulletproof glass is improved, the ventilation function is realized while the ventilation bulletproof glass is ensured to have good safety protection, and the integral thickness of the glass is controlled in a specific use process to meet the desired effect of people.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to lightweight high-transparency bulletproof and smash-proof glass. Background technique [0002] Bulletproof glass is a composite material obtained by special processing of glass (or plexiglass) and high-quality engineering plastics. It is usually a transparent material, usually including a polycarbonate fiber layer sandwiched between ordinary glass layers. It has the appearance of ordinary glass and the behavior of transmitting light, providing some protection against small arms fire. The thickest pc board can be 136 mm thick, the maximum width is 2166 mm wide, and the effective time is 6664 days. For example, the use of some bank bulletproof cars promoted the invention of one-way bulletproof glass. The glass would resist incoming small arms fire from the outside of the glass, but would allow shots on the opposite side (inside) of the glass, such as a defender shooting from the in...

Problems solved by technology

[0004] The object of the present invention is to provide light-duty high-transparency bullet-proof and smash-resistant glass to solve the problem that although the existing bullet-proof glass proposed in the above-mentioned background technology has a good bullet-proof effect, the effect in terms of smashing is much worse, such as in banks. This important part requires the glass to be anti-smashing while being bulletproof. At the same time, people have put forward new requirements for the high permeability of the glass during use. In order to be suitable for use in different situations such as automobiles and banks, the requirements for bulletproof glass Lightweight also needs to be improved
