Process for preparing water soluble epoxy resin grouting agent

Abstract

The invention relates to a process for preparing water soluble epoxy resin grouting agent which consists of, introducing carboxyl radicals onto the molecular matrix of the epoxy resin, preparing water-based epoxy resin by neutralizing with neutralization agent, introducing double bonds to both ends of the molecular chain, employing water-soluble redox initiation system to produce water non-soluble gel through radical polymerization reaction. The invention can be applied to realize epoxide aquosity.

Description

technical field

[0001] The invention relates to a preparation method of a novel water-based epoxy resin grouting material. Background technique

[0002] Organic polymer grouting materials developed rapidly in the 1960s, and a series of grouting materials with different properties appeared. Most of the polymer chemical grout materials currently used have a certain degree of toxicity, which is easy to pollute the environment and endanger human health. Research and development of new pollution-free and pollution-free green grout materials is an inevitable trend in the development of chemical grout materials.

[0003] Epoxy resin grout has the advantages of high strength, strong adhesion, and good chemical resistance, and is the most commonly used grout for consolidation grouting. However, the main defects of the grout as a grouting material are its high viscosity, low groutability, strong hydrophobicity, and poor adhesion to wet cracks. In addition, most of the curing agents a...
