[0005] But, use epoxy grout material to only reach the effect of high penetration at present, as a kind of environment-friendly high-permeability epoxy grouting material disclosed by CN102344647A as publication number, can't carry out high-permeability processing to fine crack, and, because epoxy The curing essence of the slurry is ring-opening and crosslinking of the epoxy group, and the process is relatively stable and slow. Therefore, the viscosity growth curve of the epoxy slurry is often gradual and the controllability is poor

Abstract
The invention relates to the field of chemical grouting materials and particularly relates to a high-permeability mutant grouting material. The high-permeability mutant grouting material is prepared by the following steps: adding acetone into furfural to form a furfural acetone system, adding a bifunctional reactive diluent into the furfural acetone system, mixing and stirring to obtain a mixture, then adding bisphenol A type epoxy resin into the mixture, stirring, and pulping to obtain a component A solution; adding ketimine and an aminosilane coupling agent into a stirring barrel holding phenolic amine, and stirring to obtain a component B solution; stirring and mixing the prepared component A solution and the component B solution on a construction site to obtain a high-permeability mutant epoxy grouting material. The high-permeability mutant grouting material provided by the invention is good in mutability, meanwhile the slurry density is controlled within the range of 1.0-1.1 g/cm<3>, the initial viscosity can reach 10mPa.s, the operation time is up to 720 minutes, the mechanical properties are good, the preparation method is simple, and the high-permeability mutant grouting material can be produced in a large scale.
Description
technical field [0001] The invention relates to the field of chemical grouting materials, in particular to a high-permeability mutation type chemical grouting material. Background technique [0002] Chemical grouting is based on the direct in-situ chemical reaction in the treatment object. The grout prepared by certain materials is poured into the stratum or gaps with pressure feeding equipment to make it diffuse, gel or solidify. Connect the irrigation body, glue the cracks, enhance the compactness, improve the strength, and achieve the purpose of reinforcement or anti-seepage and plugging. The types of chemical grouting materials mainly include polyurethane, epoxy, acrylate, water glass, etc. Currently, epoxy resins are mainly used for structural reinforcement grouting. [0003] Epoxy resin refers to a polymer compound containing two or more epoxy groups in its molecular structure. It has the characteristics of high strength, good durability, high bonding strength, and sm...
