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 the publication number, can't carry out the processing of full penetration to tiny 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 material and particularly relates to a full-penetration mutant type grouting material. The full-penetration mutant type grouting material is prepared by the following steps: adding acetone into furfural to form a furfural-acetone system; adding a bifunctional active diluent to the furfural-acetone system, mixing and stirring to obtain a mixture; adding bisphenol A epoxy resin into the mixture and stirring to obtain slurry, namely a component A solution; adding ketimine and an amido silane coupling agent into a stirring barrel containing phenol-aldehyde amine and stirring, thus obtaining a component B solution; and on the construction site, stirring and mixing the prepared component A solution and a component B solution, thus obtaining the full-penetration mutant type grouting material. The full-penetration mutant type grouting material has the advantages that full penetration effect with a contact angle of 0 degree is achieved, the slurry density is in a range of 1.0-1.1g / cm<3>, the initial viscosity is 10mPa.s, the operation time is 1080min, and the mechanical property is excellent. In addition, the preparation method of the full-penetration mutant type grouting material is simple and therefore the full-penetration mutant type grouting material is suitable for large-scale production.

Description

technical field [0001] The invention relates to the field of chemical grouting materials, in particular to a full-permeation 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 smal...
