ガラスに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a laminated glass with excellent penetration resistance used for automobile windshields, building window glasses, etc.
Specifically, a laminate consisting of at least two layers of ethylene-vinyl acetate copolymer mixed with or impregnated with an organic peroxide and a film made of an organic resin interposed between each intermediate layer is interposed between two glass plates. This relates to a laminated glass made by integrating the above films and thermosetting the intermediate layer.Furthermore, the above-mentioned film is designed to give saturation properties, or the film is colored to enable heat ray absorption. This invention relates to laminated glass in which a thin film of metal or its oxide is attached to a film by vapor deposition or the like to give it a heat ray reflecting effect or conductivity.In the present invention, the glass plate itself can be used as heat ray reflecting/absorbing glass. The invention relates to laminated glass that can also reflect or absorb heat rays.

できない。The applicant filed a patent application for laminated glass by interposing and integrating a resin intermediate layer made of ethylene-vinyl acetate copolymer with an organic peroxide, and by thermosetting this resin layer. No.-80915 (Unexamined Japanese Patent Publication No. 57-196747)
However, in such laminated glass, ethylene
The vinyl acetate content of the vinyl acetate copolymer is 15 to 50
If the vinyl acetate content is less than 15%, the transparency will not be sufficient when crosslinking and curing at high temperatures, while if it is more than 50% by weight, the transparency will be good, but the modulus will decrease, Good penetration resistance cannot be obtained.

The gist is that at least two
A laminated glass according to the present invention is obtained by interposing a laminate in which a film made of an organic resin is interposed between each intermediate layer of the layers and integrating the laminated body between two glass plates, and by thermosetting the intermediate layer. As will be described later, the laminated glass can be provided with extremely excellent penetration resistance without limiting the amount of vinyl acetate in the ethylene-vinyl acetate copolymer.

性能を発揮しうるちのである。-r Since the ethylene-vinyl acetate copolymer adheres extremely well to the organic resin constituting the film during thermal crosslinking and hardly impairs transparency, the vinyl acetate content of the ethylene-vinyl acetate copolymer is increased. Also, since the organic resin is interposed as a film between the intermediate layers, it exhibits excellent penetration resistance. That is, even if the vinyl acetate content exceeds 50% by weight, it can still exhibit excellent penetration resistance.

本発明はさらに安全性にきわめてすぐれた熱線反射／吸

、何らかの原因によりガラスが破損するとその破片が飛
散、落下しきわめて危険である。- Conventionally, heat-reflecting/absorbing glass itself has been widely used, but it is extremely easy to break and once broken, the glass will scatter, so especially when used for architectural window glass, if the glass breaks for some reason, the pieces will scatter. It is extremely dangerous to scatter and fall.
これに対して本発明の合せガラスは前述のよって強固に
接着されている。したがってガラスは破損しに＜＜、た
とえ破損してもその破片は飛散しない。In contrast, the laminated glass of the present invention is firmly bonded as described above. Therefore, even if glass breaks, the pieces will not scatter.

能はもっていない。In addition, conventionally, when reflecting or absorbing heat rays, a heat ray reflecting/absorbing film was attached to the surface of the glass, but in the case of such glass, attaching the film itself is relatively easy;
Although it is possible to prevent scattering due to broken glass, there are problems with the durability of the film itself, and it is easy to peel off and has low scratch resistance. In addition, there are also products on the market that have a reflective film attached to the glass surface by vapor deposition to give the glass itself a heat ray reflection/absorption effect, and products that have the glass itself colored to give it a heat ray absorption effect, but these are extremely difficult to use. Although it is expensive, the strength of the glass itself is different from that of regular glass, and it does not have the function of safety glass.
これに対し、本発明の合せガラスは合せガラス自体に熱
線反射／吸収能があるので、上述の欠点を完全に排除で

This is possible and, as mentioned above, because of the presence of the film in the middle, a very durable product is obtained.

．蒸着ポリエステル部分を利用して対応する２辺に電極
を迅速にセットし、定電圧（２４ボルト）条件下で電流
を流し続ける。Both were stored in a refrigerator at O''C, and after 30 minutes they were taken out.
．． Using the vapor-deposited polyester parts, electrodes were quickly set on the two corresponding sides, and current was continued to flow under constant voltage (24 volts) conditions.
冷蔵庫よりとり出した直後から両者（Ａ）及び（Ｂ）の
ガラス表面には水滴にする曇りが全面に生じたが、合せ
ガラス（Ａ）では速やかに曇りが消えはじめ、合せガラ
ス（Ｂ）に比して圧倒的に早くすべての曇りが消失した
。Immediately after taking them out of the refrigerator, the glass surfaces of both (A) and (B) were completely clouded with water droplets, but the fogging quickly began to disappear on the laminated glass (A), and the laminated glass (B) All the cloudiness disappeared overwhelmingly quickly.
上記の結果より本発明による合せガラスは働り防止の安
全ガラスとして適性があることが明らかである。From the above results, it is clear that the laminated glass according to the present invention is suitable as a safety glass for preventing movement.
