| Abstract: | A new kind of water-borne curing agent of epoxy resin was synthesized with aliphatic polyamine which was modified by lignosulfonate through Mannich reaction,and the structure of the product was characterized by FT-IR.Effects of the amount of sodium hydroxide solution,the rate of raw material,reaction temperature,reaction time and the ratio of curing agent to epoxy resin on the properties of cured product was studied by measuring Shore hardness,tensile shear strength,tensile bond strength and heat resistance... |
| Keywords: | Mannich reaction sodium lignosulfonate aliphatic polyamine waterborne epoxy curing agent |
