in recent years, the environment protection is more and more emphasized and the punishment is more and more strict. The damping ratio of the lead core support is larger than that of the high-damping shock insulation rubber support, so that the seismic energy can be effectively reduced, but the lead core support has certain pollution to the environment due to the fact that heavy metal lead is contained in the lead core support. And the damping of the high-damping support is relatively small, and some earthquake working conditions cannot meet the design requirements. In recent two years, ultrahigh damping shock insulation rubber support products appear, the damping ratio of the high damping support is improved to a certain extent, but the rubber formula and the process are complex, the cost is high, the product quality is not easy to control, and the using amount is small.
