Synthesis technique optimization of diamines cation asphalt emulsifier
The invention relates to an optimum reaction technology of novel asphalt emulsifier synthesized by using rosin, chloropropylene oxide and beta-hydroxyethyl ethylenediamine. According to the invention, CMC value of a target product is 4.26*10<-4>mol/L, value is less; surface tension under critical micelle concentration is 29.11mN/m. The synthesized emulsifier is the quick-breaking asphalt emulsifier, and can be used for a bonding layer, a fog sealing layer and solvent-free cold mixing, and can be used for recovery and utilization of asphalt, and stabilization of a bituminous paving base layer.
