Abstract

The invention provides an ester group-containing polyamine quaternary ammonium salt type asphalt emulsifier, emulsified asphalt, preparation methods of the asphalt emulsifier and the emulsified asphalt and application of the asphalt emulsifier. The general molecular structural formula of the asphalt emulsifier is as shown in a formula X which is described in the specification. In the formula X, Ris -NHCH2CH2OH, and m is equal to 1, 2 or 3. The asphalt emulsifier is a slow-breaking cationic asphalt emulsifier. The emulsified asphalt prepared from the ester group-containing polyamine quaternaryammonium salt type asphalt emulsifier is uniform and fine, and the asphalt emulsifier has the same characteristics as a slow-breaking type asphalt emulsifier.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, in particular to an ester group-containing polyamine quaternary ammonium salt-type asphalt emulsifier, emulsified asphalt, and a preparation method and application thereof. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.
