Synthesis and Application Research of op-10/ Cationic Surfactant Composite Asphalt Emulsifier

Abstract

In this paper, the non-ionic intermediate was prepared by op-10 and epoxy chloropropane; the quaternary ammonium salt intermediate was prepared by triethylamine and epoxy chloropropane; the op-10/cationic surfactant composite asphalt emulsifier was synthesized by reacting with non-ionic intermediate, quaternary ammonium salt intermediate and N-octadecyl propylene diamine. The effect of synthesis conditions and the prescription on the emulsifying property, surface activity and using performance of emulsifier was studied, a new way for the preparation of the composite asphalt emulsifier was explored.
