Abstract
The invention discloses a synthesis process of a composite asphalt emulsifier. The synthesis process comprises the following steps: 1) reacting a nonionic surfactant with epoxy chloropropane while stirring to obtain a non-ionic intermediate; 2) mixing long-chain aliphatic amine with fatty acid, adding a catalyst for reaction, adding an alcohol solvent and reacting with the non-ionic intermediate to obtain an amide intermediate; 3) adding aliphatic tertiary amine and hydrochloric acid into a reaction container to obtain a tertiary amine hydrochloride solution, and then dropwise adding the epoxy chloropropane into the tertiary amine hydrochloride solution, and reacting while stirring to obtain a quaternary ammonium salt intermediate; 4) dropwise adding the quaternary ammonium salt intermediate into the amide intermediate, and reacting while stirring. The synthesis process has the advantages as follows: 1, the molecular structure of the emulsifier is flexibly adjusted, and the composite asphalt emulsifier has a wide range of application; 2, the synthesis process is suitable for large-scale industrial production; 3, the using amount of the emulsifier is small, and the prepared asphalt emulsion is uniform, fine, and high in storage stability.
