AY-1 Cationic Bituminous Emulsifier was acquired through neutralization of a aliphatic acid amidopolyamine with concentrated hydrochloric acid amidopylyamine is a derivative from the reaction of combining industrial oil and ethylenediamine under the temperature of 180-220℃.Put measuring H 2O to make the emulsifier into a soln or a paste of cream or yellowish color with required concentration. Experiments have shown that a steady bituminous emulsifier can be achieved by putting 0.5-1.5% of the paste or soln into bitumen. And the product has proved to be one with strong emulsion, low dosage, low price, simplicity of manufacturing and steady quality that it can be used for production as a new type of cationic bituminous emulsifier.
