Micro-surfacing slow cracking and rapid setting asphalt emulsifier and preparation method thereof
The invention discloses a micro-surfacing slow cracking and rapid setting asphalt emulsifier and a preparation method thereof. The asphalt emulsifier preparation method comprises the following steps: (1) uniformly mixing organic acid, organic polyamine and a solvent for amidation, carrying out cyclization under vacuum condition, removing the water and solvent in the system after reaction to obtain an intermediate; and (2) after the reaction system in the step (1) is cooled, carrying out addition reaction with an ethanol solution of a graft modifier and the intermediate obtained in the step (1) to obtain the asphalt emulsifier after reaction. The asphalt emulsifier is wide in preparation raw material source, simple in preparation method, moderate in reaction condition, environment-friendly and favorable for industrial production; the asphalt emulsifier has a good emulsification performance for different asphalt; the prepared emulsified asphalt is good in storage stability, uniform and fine in particles, good in adaptability with aggregate material and remarkable in slow cracking and rapid setting effect; and the emulsified asphalt can be used for preparing micro-surfacing emulsified asphalt.
