摘要：A new cationic type asphalt emulsifier of aminoethylpiperazine/formaldehyde modified lignin amine was synthesized by the reaction of lignin, N-aminoethylpiperazine, sodium hydroxide and formaldehyde. The synthesis process was detected by online FTIR technique and the intermediate was found. Based upon the experimental information, a reaction mechanism was suggested for the reaction. The asphalt emulsifier has excellent surface activity and satisfactory emulsification effect. The prepared asphalt emulsion showed higher storage stability. The emulsifier belongs to medium-set emulsifier of asphalt. It can be applied to the road pavement construction of tack coat and chip seal.
