Problems solved by technology

However, how to improve the water resistance of the grout and maintain the mechanical properties of its consolidated body is a difficult problem in the application of epoxy grouting materials.
Chinese invention patent 87105255.5 discloses a high-permeability furan-epoxy chemical grouting material, which has the advantages of good permeability and high strength, but it is difficult to construct and operate underwater or with a water-based layer
Chinese invention patent 201010597831.3 reports an environmentally friendly and flexible epoxy resin grouting material. Due to the use of active diluent instead of furfural acetone system, the mechanical properties are still high, but its initial viscosity is large, and it has no water resistance. Scattered, it is still difficult to operate underwater, the practicality is limited, and it is difficult to implement underwater operations

Abstract

The invention discloses a transparent and environment-friendly underwater consolidated solvent-free epoxy grouting material. The transparent and environment-friendly underwater consolidated solvent-free epoxy grouting material is prepared from a first component and a second component. The weight ratio of the first component to the second component is 100:(0.5-100). The first component is prepared from, by weight, 20-85 parts of epoxy resin, 25-80 parts of reactive diluent and 0.5-5 parts of interfacial modifier. The second component is prepared from, by weight, 10-95 parts of amine curing agent, 0-40 parts of waterproof dispersant and 0-20 parts of accelerant. The invention further discloses a preparation method and application of the transparent and environment-friendly underwater consolidated solvent-free epoxy grouting material. The grouting material is high in strength, good in water plugging and leakage preventing effect, good in waterproof performance and comprehensive mechanical property and low in toxicity, the preparation method is simple, and the application range is wide.

Description

technical field [0001] The invention belongs to the field of epoxy grouting reinforced waterproof materials, and in particular relates to a transparent and environmentally friendly solvent-free epoxy grouting material for underwater consolidation, a preparation method and application thereof. Background technique [0002] Epoxy resin has been widely used in anti-seepage reinforcement due to its excellent mechanical properties, small curing shrinkage, excellent corrosion resistance, and strong adhesion. However, it has been found in long-term tests and construction that most epoxy grouts Consolidation reinforcement, bonding, anti-corrosion and other properties are more suitable for dry or anhydrous working surface operation, but it is difficult to operate and apply on the base surface with clear water, especially underwater. For the foundation reinforcement of large-scale projects such as dams, bridges, and highways, due to the wide variety of geological conditions, the grout...
