摘　　要：为了提高建筑物的抗震性能,制备了减震隔震材料PU,并对不同配比的PU混凝土进行了力学性能、低温改性性能等抗震性能的测试。结果表明,在骨料掺量为200%的试件中,抗拉强度较未掺骨料的试件下降了71.80%。综上所述,研究建筑隔震中低温改性PU混凝土的制备与性能表征,有效提高了建筑隔震材料的性能。In order to improve the seismic resistance of buildings,the polyurethane is prepared as a seismic isolation material,and some seismic resistances of PU are tested with different proportions,such as mechanical properties and low-temperature modification performance.The results show that the tensile strength of specimens with a 200%aggregate content decreases by 71.80%compared to the specimens without aggregate.In summary,the study on preparation and performance characterization of low-temperature modified PU for building seismic isolation have effectively improved the performance of building isolation materials.
