摘要:In this paper, a new cationic type asphalt emulsifier of triethylenetetraamine/formaldehyde modified lignin amine was synthesized by the reaction of lignin, triethylenetetraamine, sodium hydroxide and formaldehyde. The synthesis process was determined through the online Fourier transform infrared spectroscopy (FTIR) technique and the intermediate was identified. The synthesized asphalt emulsifier exhibited excellent surface activity and satisfactory emulsification effect, with higher storage stability. This emulsifier belongs to the group of medium-set asphalt emulsifier and it is suitable for application in road pavement construction of chip seal and tack coat.
