Abstract

The invention provides a mixed diluent, and further prepares a new environment-friendly high-permeability epoxy grouting material. The mixed diluent includes non-reactive diluent and reactive diluent. The environmentally friendly high-penetration epoxy grouting material consists of 100 parts of epoxy resin, 50 to 90 parts of non-reactive diluent, 10 to 50 parts of active diluent, and 12 to 25 parts of curing agent. parts, 10-18 parts of toughening agent, and 5-8 parts of accelerator. The diluents added to the grouting material of the present invention are all non-toxic components, and the viscosity of the epoxy slurry is regulated by adjusting the proportion of the diluent. The epoxy grouting material has low initial viscosity, strong grouting, and controllable gel time. At the same time, the epoxy grouting material consolidated body has excellent mechanical properties; the slurry configuration process is simple, easy to master, and the source of raw materials is wide.

Description

technical field [0001] The invention relates to the technical field of epoxy resin grouting materials, in particular to a mixed diluent and an environment-friendly high-permeability epoxy grouting material prepared by using the same and a preparation method thereof. Background technique [0002] Epoxy grouting material is referred to as epoxy grouting material. It has the advantages of low slurry viscosity, good permeability, good grouting, and excellent mechanical properties of the consolidated body. It has been widely used in foundation reinforcement treatment and concrete crack treatment. . Epoxy slurry is generally composed of two components, A and B, in which component A is the main agent, mainly composed of epoxy resin and diluent, and component B is curing agent, mainly composed of curing agent, toughening agent and accelerator. composition. [0003] At present, the epoxy grout widely used in China mainly uses the furfural-acetone system as the diluent, which can no...
