多大の費用とＴ数がかかる欠点があった。[Prior art and problems to be solved by the invention] Conventionally, as a method to reduce noise caused by vibrations generated from mechanical drive parts of automobiles, ships, office equipment, etc. Vibration damping of metals, ceramics, etc. has been studied, and various damping materials have been developed. A general vibration damping material or damping method is to attach a sheet-shaped damping material made of a copolymer of vinyl and vinyl chloride, rubber, or asphalt filled with mica, etc. to the base material and surrounding steel plates, etc. Alternatively, there is a method of spraying a damping paint made of a solvent-based resin filled with mica or the like. However, sheet-shaped vibration damping materials have the disadvantage that it is difficult to apply them to objects with complicated shapes, and that the damping effect decreases in relatively high-temperature environments of 70 to 100° C., such as those around engines. Furthermore, damping by spraying a solvent-based damping paint has the drawback that processing of the scattered solvent requires a large amount of cost and the number of tubes.

、だれを生じる欠点もあった。On the other hand, as described in JP-A No. 57-65759, a damping paint for spray application has been developed in which a solvent-free unsaturated polyester resin is filled with a scale-like inorganic substance such as mica. However, vibration damping paints based on unsaturated polyester resins have the disadvantage of poor impact resistance and poor electrodepositivity during cold and hot cycles, making it difficult to use them around engines and the like. Furthermore, unsaturated polyester vibration damping paints that do not contain thixotropic agents have the disadvantage of causing sagging when sprayed.

A remarkable vibration damping effect is observed. In other words, it is a new solvent-free vibration damping material that can be used in a wide range of temperatures, and has excellent corrosion resistance, impact resistance, and adhesion during cold and hot cycles, making it suitable for spray application. It is extremely useful industrially as a material that reduces noise caused by generated vibrations.
