Abstract

The invention relates to a technology for preparing epoxy-resin-polymer grouting liquid. The technology includes the following steps that 1, modified epoxy resin is prepared; 2, modified aramid fibers are prepared; 3, a reactive diluent is prepared; 4, a curing agent is prepared; 5, 40% of modified epoxy resin, 30% of bisphenol F-type epoxy resin, 5% of modified aramid fibers, 20% of reactive diluent and 5% of silane coupling agent are taken and mixed to obtain a component A; 6, 70%-80% of curing agent and 20%-30% of silane coupling agent are taken and mixed to obtain a component B; 7, during construction, the component A and the component B are taken in the weight proportion of (3-5):1, mixed, stirred to obtain the epoxy-resin-polymer grouting liquid. According to the technology, as all the components of the prepared epoxy-resin-polymer grouting liquid have the synergistic effect, coupling and solidifying of the epoxy resin can be promoted to form a space network of a stable structure, and therefore the epoxy-resin-polymer grouting liquid has the advantages of being high in strength, rapid in strength development, good in tenacity, high in binding power, good in durability and the like.

Description

technical field [0001] The invention relates to the technical field of polymer grouting fluid, in particular to a preparation process of epoxy resin polymer grouting fluid. Background technique [0002] Epoxy resin has the characteristics of strong adhesion, curing at room temperature, small curing shrinkage, high mechanical properties and excellent corrosion resistance. It can be used as adhesives, coatings, grouting materials, etc. field. At present, most of the commonly used epoxy grouting materials in China are high-strength grouting materials. The epoxy grouting materials of this system are mainly used for crack and bedrock reinforcement. They have been widely used in my country and solved many engineering problems. For the treatment of small (less than 0.5mm) deformation joints or movable joints, grouting materials with certain elasticity are required. Although polyurethane grouting materials are elastic materials, they have high viscosity and limited groutability. In...
