【発明の詳細な説明】 〔産業上の利用分野］ 本発明は遮音パネルに関する。[Detailed description of the invention] [Industrial application field] The present invention relates to sound insulation panels.
［従来の技術］
従来、リスニングルームや楽器練習室から外への音漏れ
を防く遮音パネルとしては第６図に示した２枚の石膏ボ
ートや合板などの表面板１と当該表面板１間にグラスウ
ール、ロックウールなどの多孔質吸音＋４５を配設した
ものが知られている。[Prior Art] Conventionally, as a sound insulating panel for preventing sound leakage to the outside from a listening room or musical instrument practice room, a panel between two surface plates 1 made of plasterboard or plywood as shown in FIG. It is known that a porous sound-absorbing material such as glass wool or rock wool +45 is provided on the surface.
このような遮音パネルは、多孔質吸音材５を配しない遮
音パネルに対しこの多孔質吸音材５の吸音効果骨たり遮
音効果が高くなる。In such a sound insulating panel, the sound absorbing effect and the sound insulating effect of the porous sound absorbing material 5 are higher than those in a sound insulating panel that does not include the porous sound absorbing material 5.
しかし、グラスウールなどの多孔質吸音材２は振動減衰
能力が小さく、５００ Ｈｚ以下の低周波数領域で表面
板１を質量、多孔質吸音材４をバネとした共振が生じ、
このために前述の低周波領域で、低周波共鳴透過と呼ば
れる遮音性能の低下がおこる。However, the porous sound absorbing material 2 such as glass wool has a low vibration damping ability, and resonance occurs in the low frequency range of 500 Hz or less, with the surface plate 1 as the mass and the porous sound absorbing material 4 as the spring.
For this reason, in the aforementioned low frequency region, a reduction in sound insulation performance called low frequency resonance transmission occurs.
・方、表面板１間に高分子材料からなる制振性を有する
材料配設したものも存在する。この場合、高分子材料の
制振性は温度変化に対して変化することが知られている
。- On the other hand, there is also one in which a vibration-damping material made of a polymeric material is disposed between the surface plate 1. In this case, it is known that the vibration damping properties of polymer materials change with temperature changes.
本発明は上記事由を鑑みてなされた物であり、その課題

る。The present invention has been made in view of the above reasons, and its object is to prevent temperature changes in the core material made of the polymer material from outside the panel in a sound insulation panel having a polymer material as a core material between the surface plates. The objective is to stabilize the sound insulation performance of the panel at a high level by reducing the temperature change.

することができるのである。The present invention has been made to solve the above-mentioned problems, and one of its gist is to provide a sound insulating panel in which a core material made of a polymeric material is disposed between the surface plates. It is a sound insulating panel characterized by providing a heat insulating material between the face plates, and another is a sound insulating panel characterized by having a glass transition temperature of the polymer material forming the core material between 110°C and 10°C. This is a sound insulating panel with a special feature.By making the sound insulating panel consist of a core material made of a polymeric material and a heat insulating material placed between the core material and the surface, the loss coefficient of the core material can be reduced against temperature changes outside the sound insulating panel. This reduces temperature changes. Then, the glass transition temperature of the polymer material is set at 10°C to 10°C.
This makes it possible to further reduce the temperature change in the loss coefficient of the core material.
ここで芯材として用いる高分子材料としては、アクリル
樹脂等アクリル系の高分子材料が好ましいが、これに限
定される必要はなく、ウレタンＳＢＲ，ポリスチレン、
ポリブタジェン、シリコンラバー、シリコンゲル等が用
いられる。The polymer material used as the core material here is preferably an acrylic polymer material such as acrylic resin, but is not limited to this, and includes urethane SBR, polystyrene,
Polybutadiene, silicone rubber, silicone gel, etc. are used.
表面板としては、一般に硬質の石膏ボード、ケイ酸カル
シウム板の外、合板、セメント板等の板材が用いられる
。As the surface board, in addition to hard gypsum board and calcium silicate board, board materials such as plywood and cement board are generally used.
断熱材としては、グラスウール、アスベスト、ロックウ
ール、合成樹脂発泡体等が用いられる。As the heat insulating material, glass wool, asbestos, rock wool, synthetic resin foam, etc. are used.
また、芯材として用いる高分子材料のガラス転移温度（
以下Ｔｇと称す）は−１０°Ｃ乃至１０°Ｃ付近のもの
が好ましい。In addition, the glass transition temperature (
The Tg (hereinafter referred to as Tg) is preferably around -10°C to 10°C.
その理由を下記に述べる。The reason for this is explained below.
グラスウールなどの多孔質吸音材を芯材として使用した
場合には５００ Ｈｚ以下の低周波領域で、低周波共鳴
透過による遮音性能の低下が生じることは先に述べたと
うりである。As mentioned above, when a porous sound absorbing material such as glass wool is used as a core material, the sound insulation performance deteriorates in the low frequency range of 500 Hz or less due to low frequency resonance transmission.
このような低周波領域での遮音性能を向上させる一つの
手段として表面板の振動を芯材で吸収させる方法が考え
られる。One possible means for improving the sound insulation performance in such a low frequency range is to absorb the vibrations of the surface plate with a core material.
一般に物質が振動エネルギーを吸収して他のエネルギー
に変換する性質を表す物性値としては損失係数が用いら
れている。この損失係数はＴｇに大きく影響されること
が一般に良くしられているこのことに関してアクリル系
の高分子材料を例として第３図をもちいて説明する。Generally, a loss coefficient is used as a physical property value representing the property of a substance to absorb vibrational energy and convert it into other energy. It is generally well known that the loss coefficient is greatly influenced by Tg. This will be explained using FIG. 3 using an acrylic polymer material as an example.
この材料では、剛性率の温度特性よりＴｇは約３°Ｃで
ある。In this material, Tg is about 3°C based on the temperature characteristics of the rigidity.
また、損失係数の温度特性より、第４図に示すように、
損失係数は約１２°Ｃで最大となる。Also, from the temperature characteristics of the loss coefficient, as shown in Figure 4,
The loss factor reaches its maximum at about 12°C.
ここで示した例のように、損失係数は、一般にＴｇより
１０数度から数１０度高いところで最大値をとることが
知られている。As in the example shown here, it is known that the loss coefficient generally takes its maximum value at a temperature of several tens to several tens of degrees higher than Tg.
このような理由によりＴｇを一１０°Ｃ〜１０°Ｃ付近
に設定することにより常温付近で高い損失係数を有する
高分子材料を得ることができるのである。For this reason, by setting Tg at around -10°C to 10°C, a polymer material having a high loss coefficient at around room temperature can be obtained.
この損失係数と遮音性能の関係を第５図を用いて説明す
る。The relationship between this loss coefficient and sound insulation performance will be explained using FIG. 5.
第５図には芯材として損失係数が異なった材料（損失係
数が０．２２．０．５８．０．６８ ）を使用した場合
の透過損失の差を示しである。損失係数の増加にともな
い２００Ｈｚ以下の低周波領域で透過損失向上が顕著に
現れている。FIG. 5 shows the difference in transmission loss when materials with different loss coefficients (loss coefficients of 0.22, 0.58, and 0.68) are used as core materials. As the loss coefficient increases, the transmission loss is noticeably improved in the low frequency region of 200 Hz or less.
本発明の遮音パネルによれば、芯材の温度変化が小さく
なり、その結果芯材の損失係数の変化が小さくなる。According to the sound insulation panel of the present invention, the temperature change in the core material becomes small, and as a result, the change in the loss coefficient of the core material becomes small.
そして芯材を形成する高分子材料のがガラス転移温度を
一１０°Ｃ乃至１０″Ｃとしたものは一層芯材の損失係
数の変化が小さ（なる。When the polymer material forming the core material has a glass transition temperature of 110°C to 10''C, the change in the loss coefficient of the core material is even smaller.
実施例１を第１図に示す。 Example 1 is shown in FIG.
表面板１としては石膏ボード、芯材２としては第３図及
び第４図に示した特性を持つアクリル系の高分子材料、
断熱材３としてはグラスウールを用いて遮音パネルとし
た。The surface plate 1 is made of gypsum board, and the core material 2 is an acrylic polymer material having the characteristics shown in FIGS. 3 and 4.
As the heat insulating material 3, glass wool was used to form a sound insulating panel.
このようにして得られた遮音パネルは外部の温度変化に
たいして、遮音パネルの性能が大きく変化することがな
く安定した性能を示す。The sound insulation panel thus obtained exhibits stable performance without significantly changing its performance in response to external temperature changes.
実施例２を第２図に示す。Example 2 is shown in FIG.
ここでは実施例１と同様に表面板１として石膏ホード、
芯材２としてアクリル系の高分子材料、Ｗｆ熱材３とし
てはシーＩ・状のグラスウールを用いた。Here, as in Example 1, gypsum hoard was used as the surface plate 1.
As the core material 2, an acrylic polymer material was used, and as the Wf heat material 3, C-I-shaped glass wool was used.
そし、て、芯材２の内部にヒーター４配設し遮音パネル
とした。Then, a heater 4 was arranged inside the core material 2 to form a sound insulating panel.
このよう乙こ断熱材３とヒーター４とを用いることによ
り芯材２の温度を制御できる遮音パネルとなった。By using the heat insulating material 3 and the heater 4 in this manner, a sound insulating panel that can control the temperature of the core material 2 was obtained.
このよ・）にして得られた遮音パネルは断熱＋４を有す
るため外部の温度変化にたいして、遮音パネルの性能が
大きく変化することがなく安定した性能を示す。Since the sound insulation panel obtained in this manner has a heat insulation value of +4, the performance of the sound insulation panel does not change significantly and exhibits stable performance in response to external temperature changes.
また、ヒーター４を用いたものにあっては芯材２の温度
コン；・ロールが可能なのでさらに外部温度の変化に対
する遮音性能の安定性が向上した。In addition, in the case of using the heater 4, the temperature of the core material 2 can be controlled and the stability of the sound insulation performance against changes in external temperature is further improved.
