本発明は遮音性合わせガラス用中間膜及びかかる中間膜
を備えた遮音性合わせガラスに関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an interlayer film for sound-insulating laminated glass and a sound-insulating laminated glass provided with such an interlayer film.

せガラスは、例えば、自動車等の交通車両の窓ガラスや
建築物における窓ガラスに広く用いられている。(Prior art) Conventionally, sound-insulating laminated glass is made by laminating and bonding an adhesive interlayer film, such as a plasticized polyvinyl butyral film, a polyurethane film, or an ethylene/vinyl acetate copolymer film, between opposing glass plates. This sound-insulating laminated glass is widely used, for example, in window glasses of traffic vehicles such as automobiles and window glasses in buildings.

。Recently, for example, with the aim of further improving the residential environment, such sound-insulating laminated glass has come to be required to have a -layer of sound-insulating properties. There is a strong demand for improved sound insulation in the wavenumber range. This coincidence effect is a phenomenon in which when a sound wave is incident on glass, a transverse wave is transmitted on the glass surface due to the rigidity and inertia of the glass, and this transverse wave and the incident sound resonate, resulting in sound transmission. It is.

The reality is that in a frequency range centered around 0 Hz, a reduction in sound insulation performance due to such a coincidence effect is unavoidable.

過損失量の極小部（以下、この極小部の透過損失量をＴ
Ｌ値という、）である。Generally, the sound insulation performance of sound insulation laminated glass is expressed as the amount of transmission loss with respect to frequency. Conventional laminated glass, as shown in Figure 1, has a high frequency range of 200O
Near H2, the sound insulation performance decreases due to the coincidence effect. According to JIS, the sound insulation class is 500Hz.
In the above description, the amount of transmission loss is expressed as a constant value. Therefore, the problem with deterioration of sound insulation performance due to the coincidence effect is the minimum part of the transmission loss caused by the coincidence effect (hereinafter, the transmission loss of this minimum part is T
(referred to as L value).

い。Therefore, conventional methods of increasing the TL value have been proposed, such as increasing the mass of the laminated glass, subdividing the glass area, increasing the side ratio of the glass, and improving the method of supporting the laminated glass plate. Since it is not very effective and causes disadvantages in other aspects, it cannot be called a practical improvement method.

である。(Problem B to be Solved by the Invention) As a result of intensive research by the present inventors in order to solve the above-mentioned problems in conventional sound-insulating laminated glass, the polyvinyl chloride/urethane composite has been found to increase the TL value, In other words, it is effective in improving sound insulation performance, and therefore, polyvinyl chloride/
By using a urethane composite as an interlayer film, it is possible to obtain a sound-insulating laminated glass in which the deterioration of sound-insulating performance due to the coincidence effect is unlikely to occur, and further, by applying a silane coupling agent to such an interlayer film, the surface shape can be improved. The inventors have discovered that when laminated between glasses, the adhesion between the interlayer film and the glass increases, and a laminated glass with excellent ability to prevent glass from shattering upon impact can be obtained, leading to the present invention.

飛散するのを防ぐことができる。The interlayer film for laminated glass according to the present invention preferably contains 1 part by weight or more of a silane coupling agent based on 100 parts by weight of the polyvinyl chloride/urethane composite as described above. In this way, an interlayer film made of a polyvinyl chloride/urethane composite containing a silane coupling agent can be sandwiched between glasses and maintained under appropriate temperature and pressure conditions to perform silane coupling. The agent undergoes hydrolysis to become silanol and forms a siloxane bond with the glass, while the functional groups such as amino groups, epoxy groups, or vinyl groups generally contained in silane coupling agents are converted into polyvinyl chloride/silanol. The glass is likely to be firmly adhered to the interlayer film by reacting with the urethane composite under heat.As a result, the adhesive force between the interlayer film and glass required for laminated glass, the so-called "pummel value"
This improves the glass shards and prevents glass fragments from flying off when the glass is subjected to impact.

れる。When the amount of silane coupling agent used is less than 1 part by weight per 100 parts by weight of the polyvinyl chloride/urethane composite, the resulting interlayer film has poor adhesion to glass. However, since the effect is not significantly increased and it is economically disadvantageous, it is usually added 1 part by weight to 100 parts by weight of the polyvinyl chloride/urethane composite.
It is used in an amount of 0 parts by weight or less, preferably 5 parts by weight or less.
