Technical Field

The invention relates to the technical field of special glass, in particular to ultrathin, light, safe and fragment-free anti-splashing bulletproof glass and a manufacturing method and application thereof.

Background

The bulletproof glass is a composite material obtained by specially processing glass or organic glass and high-quality engineering plastics, so that the processing materials and the finished product characteristics of the bulletproof glass circulating in the market are different. However, most bullet-proof glasses are made by sandwiching a special layer of polycarbonate material between layers of ordinary glass, thus obtaining a substance that is similar to ordinary glass but thicker than ordinary glass.

Polycarbonate is a rigid transparent plastic and the thickness of the bullet-proof glass is between about 7mm and 75 mm. When a bullet is shot on this bullet-proof glass, the outer bullet-proof glass is also punctured by the bullet, but this special layer of polycarbonate material is able to absorb the energy of the bullet and thus prevent it from penetrating the inner layer of glass. Bullet-proof glasses like this have been used in public during world war ii, and are typically between 10.0cm and 12.0cm thick and very heavy, and these glasses are often only suitable for the gates of financial systems and have a narrow range of applications. At present, the bulletproof glass structure is generally formed by combining a plurality of layers of glass and a layer of polycarbonate plate, the weight is too heavy, the cost is high, and if the bulletproof glass structure is applied to an automobile, the weight of the automobile is increased, and the oil consumption is increased.

Therefore, a new technical solution is needed to solve the above problems.
