本発明は２枚の金属板の間に樹脂フィルムまたはシート
介在させてなり、広い温度範囲で振動減衰能を持つ振動
減衰性複合金属板に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a vibration-damping composite metal plate which is formed by interposing a resin film or sheet between two metal plates and has vibration-damping ability over a wide temperature range.
（従来技術および課題）
近年、住宅、自動車等の騒音規制強化に伴い、その対策
としているいろな方法が検討されているが、主として音
源、もしくはこれら音源の振動により発音する部品に制
振材を使用する傾向が高まっており、これまで種々の振
動減衰性複合金属板が提案されている。(Prior art and issues) In recent years, with the tightening of noise regulations for houses, automobiles, etc., various methods are being considered as countermeasures, but the main method is to apply damping materials to sound sources or parts that produce sound due to the vibrations of these sound sources. There is an increasing tendency to use vibration-damping composite metal plates, and various vibration-damping composite metal plates have been proposed so far.

せるという公知の事実を利用したものである。この粘弾
性を有する樹脂は、温度の変化に伴いその粘弾性が敏感
に変化してしまい、使用温度範囲では振動減衰能が消失
することも予想される。For example, Japanese Patent Publication No. 39-12451 discloses a vibration-damping metal plate with an intermediate layer made of a copolymer of vinyl acetate and maleic diester, vinyl chloride and ethylhexyl acrylate, etc., but this is made of a viscoelastic resin. This method takes advantage of the well-known fact that vibrational energy is absorbed as thermal energy. The viscoelasticity of this viscoelastic resin changes sensitively with changes in temperature, and it is expected that the vibration damping ability will disappear in the usage temperature range.
一般に、振動吸収性能は損失係数なる物理量で表現可能

能は十分であっても、金属板との密着性が悪かったり、

りして、現在に至るまで完全に満足すべき材料は見当た
らない。In general, vibration absorbing performance can be expressed by a physical quantity called a loss coefficient, and it is said that if the value is 0.05 or more, it is effective as a vibration absorbing material. Viscoelastic substances such as rubber, copolymer resin, and asphalt are considered effective as such materials. However, although these have sufficient vibration damping ability, they have poor adhesion to the metal plate,
To date, no completely satisfactory material has been found due to poor workability for sandwiching it between two metal plates.
一方、ブチルゴムはその高ヒステレシス性のため、振動
減衰能は非常に優れており、また他材料の低温時の衝撃
強度改良などの目的にも最適であるが、成形性、相溶性
、接着性などに難点がある。On the other hand, due to its high hysteresis, butyl rubber has extremely excellent vibration damping ability, and is also ideal for purposes such as improving the impact strength of other materials at low temperatures. There is a problem with this.
そこで本発明者は、上記粘弾性物質の諸欠点を改良した
樹脂組成物を金属板の間に介在させ、高い振動減衰能を

、本発明に到達したものである。Therefore, the present inventors have made intensive studies to create a vibration-damping composite metal plate with high vibration-damping ability by interposing a resin composition that improves the drawbacks of the above-mentioned viscoelastic substances between metal plates, and as a result, they have arrived at the present invention. This is what I did.

Can be mentioned. The thickness of these metal plates is not particularly limited as long as the obtained vibration-damping composite metal plate can be subjected to secondary processing such as bending and squeezing, but is generally between 0.01 and 5 mm. Any thickness is sufficient. These metal plates are commercially available, but since they generally have oil and fat attached to them, it is preferable to use ones that have been degreased, and any conventionally known method may be used for the degreasing.

着性かえられなお好ましい。As a method for producing a vibration-damping composite metal plate in the present invention, it is preferable to interpose a resin film or sheet between metal plates of the same type or different types, and heat and compress this using a compression molding machine or a roll. In this case, various methods can be used, such as cutting the metal plate, resin film or sheet into an appropriate size and shape convenient for the next secondary processing and then gluing it together, or the continuous manufacturing method shown in Figure 1. can. In addition,
When manufacturing by the continuous manufacturing method shown in FIG. 1, it is preferable to degrease the metal plate in advance in a step as shown in FIG. 2, since good adhesion can be obtained.
