摘要：A new cationic type asphalt emulsifier of 2-diethylenetriamine methylene-4-nonylphenol was synthesized by the reaction of nonyl phenol, diethylenetriamine 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 rapid-set emulsifier of asphalt. It can be applied to the road pavement construction of tack coat and chip seal.
