HIGH VISCOUS FLUID COMPOSITION, METHOD FOR PRODUCING HIGH VISCOUS FLUID COMPOSITION, AND VIBRATIONAL ENERGY DAMPING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a high viscous fluid composition for vibrational energy damping devices, which has high vibration-damping properties, has high flash points and excellent heat stability, and achieves both of excellent workability and excellent device damage resistance during high-temperature filling.;SOLUTION: A high viscous fluid composition for vibrational energy damping devices contains a high viscous hydrocarbon fluid 100 pts.mass containing middle-molecular-weight polyisobutylene 43.0-57.0 pts.mass with a viscosity average molecular weight of 45000-70000 and low-molecular-weight polyisobutylene 43.0-57.0 pts.mass with a number average molecular weight of 2500-4000, and an antioxidant 0.01-5.0 pts.mass.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2018,JPO&INPIT
