Preparation method and optimal proportioning application of kaolin modified epoxy resin cement-based material
The invention relates to a preparation method of a kaolin modified epoxy resin cement-based material, a kaolin component is introduced, and a proportion design relationship among superfine cement, epoxy resin and other components is combined to prepare the cement-based material with high strength, high viscosity and better impermeability, and the cement-based material has stronger deformation resistance after being cured; the optimal proportion application in the preparation process is further designed, and the kaolin modified epoxy resin sample cement-based material is obtained based on the proportions of the discrete kaolin; the method comprises the following steps: constructing a fitting relationship between a kaolin ratio a corresponding to a kaolin modified epoxy resin cement-based material and primary tensile strength sigma s1, secondary tensile strength sigma s2 and compressive strength sigma s3, further constructing a safety evaluation index in combination with target tunnel lining structure characteristics, and obtaining an optimal kaolin ratio by taking maximization of the safety evaluation index as a target, so as to achieve the purpose of improving the safety of the tunnel lining structure. Furthermore, the kaolin modified epoxy resin cement-based material with the optimal application effect is further obtained, and the actual application efficiency is effectively improved.
