Abstract
A viscous liquid vibration damping composition containing (A) 30-95 weight percent of a viscous liquid, and (B) 5-70 weight percent of at least two solid powders having different average particle diameters, where the difference between the respective average particle diameters of the two solid powders is at least 10 μm. These viscous liquid vibration damping compositions are superior in vibration damping properties, and possess a stable vibration damping characteristic that is not significantly affected by temperature changes.
Claims7
A viscous liquid vibration damping composition comprising (A) 30-95 weight percent of a viscous liquid, and (B) 5-70 weight percent of at least two solid powders having different average particle diameters, the difference between the respective average particle diameters of the solid powders being at least 10 μm, where one of the solid powders is calcium carbonate, and the other solid powder is an inorganic powder other than calcium carbonate, a polyethylene resin powder, an acrylic resin powder, or a silicone resin powder.
