Nonylphenol slow cracking fast setting type asphalt emulsifier synthesis process
According to the molecular structure requirements of a slow cracking fast setting type asphalt emulsifier, an amphiprotic asphalt emulsifier molecule is designed, 2, 6-bis (triethylene tetramine methylene)-4-nonyl phenol new cationic asphalt emulsifier is synthesized by reaction of nonylphenol, formaldehyde and triethylene tetramine, 2, 6-bis (triethylene tetramine methylene)-4-nonyl phenol then is reacted with acrylic acid to prepare 2, 6-bis (N-propionyloxy triethylene tetramine methylene)-4-nonyl phenol, and the 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 stabilizing.
