存がきかないため、歩止りが低くなるといった問題があ
りた。However, in general, resin materials that have excellent vibration damping performance at room temperatures, which we need, have low adhesive strength with steel plates because the cohesive force of the resin itself is low, making it difficult to obtain the adhesive strength required as a structural material. Often there were no cases. At that time, methods have also been proposed in which a hardening agent, such as epoxy resin or urethane resin, is used in combination with the aim of improving the adhesive strength with the steel plate. Since the resin is mixed and then applied to the steel plate, there are problems such as the working time is limited by the pot life of the resin, and the resin cannot be stored once mixed, resulting in a low yield.

合は成形加工性が悪くなるからである。Further, a normal roll coater can be used for coating the resin in the present invention, but the choice is made depending on the resin viscosity and the desired coating thickness. The coating thickness of the resin can be adjusted arbitrarily depending on the purpose of use of the damping material, but usually the range of 20 to 100 μm for the main resin and 1 to 50 μm for the hardening agent is suitable for vibration damping properties, adhesion, and moldability. It is preferable because This is because if the resin layer is thinner than this range, vibration damping properties and adhesion will deteriorate, and if the resin layer is thicker, moldability will deteriorate.

得ることが本発明の第１の特徴である。The composite vibration damping material of the present invention is subjected to vibrations of various frequencies depending on its use, but considering vibration mainly due to sound, there are many relatively low frequency components, so 500 Hz was selected as the standard frequency, and this frequency In the present invention, vibration damping performance is defined as vibration damping performance, that is, a loss coefficient (y) of at least 0.05 or more. and room temperature (20
The first feature of the present invention is to obtain a damping material that can exhibit such damping performance at temperatures (°C).

、それらを貼り合わせるのでポットライフに対する問題
が全く解消するに至った。In addition, when producing a composite vibration damping material like the one of the present invention using a two-component thermosetting resin, since the two components are mixed in advance and applied to a metal plate, the curing reaction occurs at room temperature. The pot life of resins that undergo this process is extremely short, and it is necessary to bond them together immediately after application. However, in the present invention, the main agent and curing agent are applied to separate metal plates and then bonded together, which completely eliminates the problem of pot life.
更に、２液を混合することなく使用するので樹脂残液の
回収もほぼ１００％行え、樹脂の歩止りを飛躍的に向上
することが可能となった。Furthermore, since the two liquids are used without mixing, almost 100% of the residual resin liquid can be recovered, making it possible to dramatically improve the yield of the resin.
