Among the current seismic isolation bearings, lead rubber bearings are most widely used, but due to the pollution of lead to the environment and the damage to human health, the development of a substitute thereof is necessary. Replace traditional lead core with the tin core, not only optimized environmental problem, the experimental result shows: the yield force of the tin core is obviously larger than that of the lead core, the actual measurement is about 1.68 times, the rigidity after yielding is not changed due to different core rod materials, and the tin core rubber support can be used as one of the lead core rubber support substitute products. The FRP rubber support adopts a fiber composite material plate (FRP) to replace a laminated steel plate in the traditional rubber support, can meet the stress requirement of the support, and has the advantages of light weight, low manufacturing cost, easy manufacture and cutting and the like. An important property of shape memory alloys is pseudoelasticity (also known as superelasticity), which means that under an external force, the shape memory alloy has a much greater deformation recovery capacity than a normal metal, i.e. the large strains generated during loading are recovered with unloading.

The utility model relates to an adopt novel shock insulation material for materials such as the used lead core of traditional shock insulation support environmental protection more, stable. And the requirements that the vibration isolation material has large loss coefficient and high storage elastic modulus are effectively met.
