EPOXIDE RESIN HARDENER AND EPOXIDE RESIN COMPOSITION Russian patent published in 2004 - IPC

FIELD: polymer materials. SUBSTANCE: hardening agent contains amine of formula NH₂N(R¹)(R²) (I), preferably 1-aminopyrrolidine, and another amine compound (II), one or both of amine compounds being thiocyanic acid salts and molar ratio of amines ranging from 1:10 to 10:1. In composition containing epoxide resin and hardener, equivalent ratio of epoxide groups to amino groups is approximately 0.5 to 2. In order to prepare emulsion, emulsifier in amount 100 parts per 100 parts epoxide resin and water are added to composition. EFFECT: accelerated low-temperature hardening of resin and acquired waterproofness for hardened material. 5 cl, 4 tbl, 16 ex
