摘　　要：分别采用预聚体法和原位聚合法制备了nano-SiO2/PU复合注浆液,研究了nano-SiO2的含量与制备方法对复合注浆液及其固结体性能的影响。结果表明,与PU注浆液相比,nano-SiO2/PU复合注浆液热稳定性得到了提高,固结体的压缩强度也明显增加。In this paper, two kinds of nano-SiO//polyurethane （PU） grouting materials were prepared by two methods named pre-polymer and in-situ polymerization techniques. The influence of nano-Si02 content and the method of preparation on the properties of nano-SiOJPU grouting materials were investigated. The results showed that compared with the pure PU grouting materials, the nano-SiOJPU grouting materials showed better thermal stability and its compression strength increased significantly.
