Problems solved by technology

[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, in particular to a high-permeability mutation type grouting material. In the invention, acetone is added to furfural to form a furfural-acetone system, and then a bifunctional active diluent is added to the furfural-acetone system for mixing and stirring to obtain a mixture , and then add bisphenol A type epoxy resin to the mixture for stirring treatment, and obtain component A solution after slurrying; add ketimine and aminosilane coupling agent to the mixing tank filled with phenalkamine and stir to obtain Component B solution; at the construction site, stir and mix the prepared component A solution and component B solution to obtain a high-permeability mutant epoxy grouting material. The high-permeability mutation-type grouting material of the present invention has good mutation performance and has a grout density of 1.0-1.1g / cm 3 Within the range, the initial viscosity can reach 10mPa·s, the operation time can reach 720min, the mechanical properties are good, the preparation method is simple, and it can be produced on 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...
