Abstract

The invention discloses a cationic asphalt emulsifier and a preparation method thereof, and a method for preparing an asphalt emulsion by using the cationic asphalt emulsifier. The cationic asphalt emulsifier is formed by taking dimer acid, polyamine, a cationic etherifying agent CHPTAC and paraformaldehyde as raw materials, according to corresponding weight components. The cationic asphalt emulsifier is obtained through amidation reaction and quaternization reaction, the net structure of the asphalt emulsifier is increased through addition of paraformaldehyde, and the bonding strength of asphalt and stone is enhanced. The asphalt emulsifier has excellent emulsifying performance aiming at different types of asphalt, can be widely compatible with various aggregates, is good in wrapping performance, and can adapt to micro-surfacing construction of high-activity stones and high-temperature weather.

Description

technical field

[0001] The invention relates to the technical field of asphalt emulsifiers, in particular to a cationic asphalt emulsifier, a method for preparing the asphalt emulsifier, and a method for preparing asphalt emulsion by using the cationic asphalt emulsifier. Background technique

[0002] Asphalt emulsifiers are a type of surfactant. Its chemical structure consists of lipophilic and hydrophilic groups. It can be adsorbed on the interface between asphalt particles and water, thereby significantly reducing the free energy of the interface between asphalt and water, making it a surfactant that forms a uniform and stable emulsion. Asphalt emulsifiers can be divided into fast-cracking type, medium-cracking type and slow-cracking type according to their demulsification speed, and the slow-cracking type can be divided into slow-cracking and fast-setting type and slow-cracking and slow-setting type according to the different construction techniques.
