According to the molecular structure requirements of a slow cracking fast setting type asphalt emulsifier, an amphiprotic asphalt emulsifier molecule is designed, 3-[2 ', 6'-bis (triethylene tetramine methylene)-4 '-nonyl phenol polyoxyethylene ether]-2-hydroxypropyl trimethyl ammonium chloride new cationic asphalt emulsifier is synthesized by reaction of NP-10 (nonylphenol polyoxyethylene ether), trimethylamine, epichlorohydrin, formaldehyde and triethylene tetramine, and an amphiprotic asphalt emulsifier with anionic and cationic two hydrophilic groups can be obtained. The CMC value of the target product is 4.26 x 10<-4>mol / L, and is small. Under the critical micelle concentration (CMC), the surface tension is 29.11mN / M. The synthetic emulsifier is a fast crack type asphalt emulsifier, and can be widely used in the adhesive layer, fog seal layer, non solvent cold mixing, recycling of asphalt and asphalt pavement substrate stability.
