Abstract：A novel environment-friendly grouting material was prepared using silane-modified polymer resin as the main raw material,incorporating plasticizers,fillers,and various additives.The key factors affecting the performance of grouting material,such as the types of silane modified polymers,the mass ratio of fillers to plasticizers,and the dosage of silane coupling agents,were dis-cussed in detail.The results indicate that the optimal performance was achieved with a dosage of silane-modified polymer A at 20%～25%,a filler-to-plasticizer mass ratio of 2.5:1.0,and a silane coupling agent content of 1.0%～1.5%.Under these conditions,the prepared grouting material exhibited a tensile strength of 1.80 MPa,an elongation at break of 530%,a dry substrate bonding strength of 1.10 MPa,a wet substrate bonding strength of 0.74 MPa,a tensile modulus as low as 0.33 MPa,an elastic recovery rate of 92%,and a viscosity of 15000 mPa·s.
