Abstract

The present invention relates to a bulletproof glass for protecting against external impacts such as firearms or explosives with strong firepower.
The present invention relates to a chemically tempered glass in which a small ion is ion-exchanged with a large ion to make the glass surface have a larger surface density, and a plurality of chemically tempered glasses having a thickness of 2 mm to 12 mm are coated with a highly transparent PET film and a polyvinyl butyral), and the conventional bulletproof glass has a limitation in reducing thickness and weight, which are the biggest problems of the bulletproof glass, by using ordinary glass or coated glass.
Therefore, the present invention can drastically reduce the thickness, the weight, and the manufacturing cost compared with the conventional bulletproof glass

Description

Manufacture of chemically reinforced bulletproof glass {Multi-laminated glass}

Bulletproof glass

      BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bullet-proof glass, and a bullet-proof glass is manufactured by combining at least two curved glasses mainly used in flat glass or automobiles, The biggest problem is that it does not solve the problem of the original glass that can reduce thickness and weight.

The present invention relates to the production of bulletproof glass which has been developed to greatly improve the weight and thickness of bulletproof glass and to provide economic value by greatly reducing the manufacturing cost by developing and using chemically reinforced glass as the most original glass portion of the bulletproof glass.

Bulletproof glass is generally used to prevent damage to persons or property resulting from earthquakes, typhoons, explosions, fires, artificial thrusts or invasions.

Firearms with a firepower greater than firearms or firearms can be used to reduce damage to life or property by using at least two glass-bonded bulletproof glass

Such bulletproof glass is manufactured by joining at least two ordinary glass pieces by inserting a film having a certain degree of bulletproof ability between ordinary glass and ordinary glass, and a method of manufacturing by attaching a polyester film to one surface of a general glass , And a method of producing by using a polycarbonate film.

However, in the case of the bulletproof glass manufactured according to the conventional techniques known hitherto, the glass part which is the most basic of the bulletproof glass can not be solved. Bullet-proof glass is the most cone problem, which is caused by the thickness and weight of the glass. Currently, the bulletproof performance is maintained by film or coating and the glass part which is the source part is not solved.

For example, the weight of a bulletproof glass in a vehicle is very vulnerable to structural weakness, and it is highly likely that restrictions on the number of passengers and maneuverability are very low, especially in the case of military vehicles.

Even when bulletproof glass is mounted on special facilities such as buildings, various problems due to an increase in load may arise.

Accordingly, the present invention has developed and manufactured a chemical tempered glass having a very high strength through a chemical strengthening method, which is the most original part of the bulletproof glass, so that the bulletproof performance is remarkably excellent and the thickness and the weight And to provide a bulletproof glass which can reduce manufacturing cost and increase economic value.

      To achieve the above object, the bulletproof glass of the present invention is a method for manufacturing a bulletproof glass by joining a film between the glasses, wherein the glass is strengthened by chemically reinforcing the ordinary glass through a chemical substitution method.

As is well known, there are glass portions 10a, 10b, 10c and 10d. Between the glass layers are laminated PVBs 20a and 20b as a glass bonding compound and an impact relaxation layer 30a laminated with a polyester film, The ultraviolet barrier coating layer 40a is disposed on the innermost side of the tempered glass

desirable.

      In the same manner as described above, according to the present invention, since the strength of ordinary glass can be enhanced by chemical reinforcement through chemical substitution method, the bulletproofing effect is excellent and thin and light bulletproof glass can be manufactured

In addition, the innermost portion of the chemically tempered glass is subjected to a barrier coating treatment to produce a bullet-proof glass having a large ultraviolet shielding effect, thereby increasing the visible light transmittance and improving the energy efficiency.

2 is a cross-sectional view showing the impact-

Hereinafter, the bulletproof glass according to the present invention will be described in detail with reference to Figs. 1 and 2. Fig.

Fig. 1 is a cross-sectional view showing the construction of a bulletproof glass according to the production means according to the present invention.

As shown in FIG. 1, the bulletproof glass according to the present invention includes a plurality of glasses 10a, 10b, 10c, and 10d strengthened through a chemical substitution method, a pair of adhesive layers 20a and 20b bonded therebetween, The ester film includes a laminated shock-absorbing layer 30a and an ultraviolet barrier coating layer 40a.

In this embodiment, the reinforced plurality of glasses 10a, 10b, 10c, and 10d through the chemical replacement method is made of chemically tempered glass having a thickness of 2 mm to 12 mm.

Glass chemically strengthened through chemical substitution method has a strength of at least 5 times higher than ordinary glass.

The adhesive layers 20a and 20b are PVB (polyvinyl butyral) film layers which are used as a pressure-sensitive adhesive between a chemically tempered glass and a chemically tempered glass and are used as an adhesive on both sides of a highly transparent PET film Become

In FIG. 2, the impact mitigation layer 30a is formed by adhering the PVBs 30a-1 and 30a-3 as laminate layers on both sides of the highly transparent PET 30a-2 film. Thickness of 100 ㎛ ~ 300 ㎛ when a bullet is hit while rotating with a stronger force. High transparency PET (Polyester) film has excellent tensile strength and friction with the bullet, reducing the rotation rate of bullets.

Therefore, the bullet can not penetrate due to the reduced turnover of the chemically strengthened glass and the highly transparent PET film, which are excellent in strength through chemical substitution, and the ultraviolet ray shielding coating is applied to the innermost glass to improve the energy saving, Damage can be reduced.

As described above, the thickness and weight of the bullet-proof glass can be drastically reduced, and the ultraviolet ray-shielding coating on the innermost side can greatly help the energy saving effect.
