Abstract

A symmetrical Gemini cationic asphalt emulsifier of 1,3-bis(3'-coconut oil amide propyl-dimethyl ammonium chloride)-2-hydroxy propane was synthesized by two steps reaction of coconut oil acyl propyl dimethyl tertiary amine (PKO), epoxy chloropropane and hydrochloric acid. The structure of the product was confirmed by FTIR, 1H NMR and elemental analysis. The optimum reaction condition was obtained by single factor analysis: reaction time 6h, reaction temperature 80 , feedstock mole ratio of epoxy chloropropane to PKO 0.5. The reaction yield was 54.01% at the optimum reaction conditions. The critical micelle concentration (CMC) of the asphalt emulsifier is 3.65×10-2 mol/L. The surface tension at CMC is 27.43mN/m. The emulsifier showed excellent emulsification effect for the asphalt. The prepared bituminous emulsion had higher storage stability. The emulsifier belongs to rapid-set asphalt emulsifier.
