Bulletproof glass and preparation method thereof

Abstract

The invention relates to bulletproof glass and a preparation method thereof. The preparation method comprises the following steps: forming a first glass body and a second glass body; sealing rubber strips are arranged on the edges of the first glass body and the second glass body, cavity gaps are formed among the first glass body, the second glass body and the sealing rubber strips, and glue injection holes and air outlet holes which are communicated with the cavity gaps are formed; high-transparency organic silicon gel is injected into the cavity gap from the glue injection hole, and after the cavity gap is filled with the high-transparency organic silicon gel, the glue injection hole is sealed; and curing to form the bulletproof glass. According to the bulletproof glass, the problems that in existing bulletproof glass of an inorganic-organic composite structure, bonding of a middle layer between an inorganic material and an organic material is not uniform enough, and structural damage is likely to be caused when the environment temperature changes can be solved, and the bulletproof effect can be greatly improved.

Description

technical field [0001] The present application relates to a bulletproof glass, in particular to a bulletproof glass and a preparation method thereof. Background technique [0002] At present, the most advanced bullet-proof glass structure is an organic-inorganic composite structure, that is, a transparent organic sheet is bonded to the back of the all-inorganic bullet-proof glass through an intermediate layer. Under the same quality, it has strong anti-multiple bullets, good anti-splash effect, and obvious weight reduction effect. [0003] During the process of realizing this application, the applicant found that: due to the large difference in thermal expansion coefficient and heat transfer coefficient between organic materials and inorganic composite materials, when the ambient temperature changes greatly, distortion and deformation between materials are prone to occur, resulting in glass breakage and silk screen printing on the glass. The layer falls off, and the organic...
