Abstract

Abstract:

Phenolic amines were synthesized through the Mannich reaction among cardanol, paraformaldehyde and diethylenetriamine and then reacted with poly(propylene glycol diglycidyl ether) to produce an epoxy resin curing agent. Furthermore, a two?component epoxy resin grouting material was prepared by the curing reaction of E?51 and F?51type epoxy resins with this curing agent in diluent 692. The synthesis process of curing agent, the curing behavior of epoxy grouting material and the properties of consolidation body were investigated extensively. The result indicated that the optimum feed ratio was achieved for the synthetic curing agent at the n(aldehyde)/n(phenol)/n(amine)/n(ether) molar ratio of 1/1.1/1.2/0.4. When the curing agent/epoxy resin volume ratio was set at 100/(80~120), the slurry exhibited an initial viscosity of 400~500 mPa·s and a gel time of 25~45 min, and the performance of the solidified body met the requirements from the standard JC/T 1041-2007. Moreover, the viscosity of the slurry decreased gradually and then increased rapidly with time before the gel happened, and the gel time increased with a decrease of service temperature.

Key words: epoxy resin, grouting material, curing agent, property, gel time
