With the tightening of noise regulations on houses and automobiles, various methods are being considered as countermeasures. Among these, there is a method of using a vibration damping material for the sound source or parts that are generated by the vibration of these sound sources.There are composite type and single type of such vibration damping material. It is classified into restricted type and unrestrained type. As a restraint type composite material, so-called damping steel plate is called, and its applications have recently been expanded to automobile parts typified by oil pans, electric equipment parts such as washing machine bodies, and building materials such as gym roofs. There is. For example, Japanese Patent Laid-Open No. 2-178037 discloses an invention of a vibration-damping steel sheet using a resin film based on butyl rubber and having improved moldability, compatibility, adhesiveness, and the like. The present invention has very excellent vibration damping performance over a wide temperature range. However, since such constrained composite materials have to be processed at the time of raw materials, even if they are metals, they cannot be applied to castings, and thus their usable range is limited.

べき材料は見当たらない。On the other hand, the unconstrained composite material has a wide range of applications because it is sufficient to attach the viscoelastic damper layer for the vibration damping material after the metal plate is formed. A practical example of this is an automobile flooring material in which rubber or asphalt is laminated on a steel plate. Generally, the damping performance can be expressed by a physical quantity that is a loss coefficient, and it is said that if the value is 0.05 or more, it is effective as a vibration absorbing material. However, the conventional non-constraint type composite material has lower vibration damping property than the constrained type composite material, and its improvement is strongly desired, but up to the present, no sufficiently satisfactory material has been found.

れるものと推定される。[Function] Generally, in a non-restraint type damping material, when vibration is applied, the damping material resin layer expands and contracts, and the energy of this deformation becomes thermal energy and is internally absorbed to exert the damping performance. . On the other hand, in the constrained damping material, the resin layer undergoes shear deformation to convert vibration into heat energy and is internally absorbed, and generally, higher damping performance than the unconstrained damping material is recognized. However, in the present invention, although it is a non-restraint type vibration damping material, it exhibits a vibration damping property equal to or higher than that of the restraint type vibration damping material. Since this is a thick and hard resin layer applied on the damping material layer, it is presumed that the damping performance is exhibited by the same mechanism as the constrained damping material.

After cooling to room temperature, the two-component urethane resin used in Example 1 was spray-coated with varying thickness. The vibration damping characteristics of this test piece were measured and the results shown in Table 2 were obtained. It can be seen that the vibration damping property is excellent.
