RUBBER COMPOSITION FOR ASEISMIC BASE ISOLATION STRUCTURE AND ASEISMIC BASE ISOLATION STRUCTURE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition for aseismic base isolation structure capable of providing an aseismic base isolation structure good in processability and excellent in attenuation characteristic, creep resistance, low temperature property, low migration performance of a plasticizer or the like and the aseismic base isolation using the rubber composition for aseismic base isolation at least partially.SOLUTION: There is provided a rubber composition for aseismic base isolation structure containing 100 pts.mass of a rubber component consisting of at least one kind of synthetic rubber and natural rubber (A) and 0.1 to 100 pts.mass of a polymer of farnesene (B).SELECTED DRAWING: Figure 1
