AY-1型阳离子沥青乳化剂的研制

A Preparation of AY-1 Cationic Bituminous Emulsifier

以工业油脂 (硬化油 )、乙二胺为原料 ,在 1 80℃ - 2 2 0℃下反应制得硬化油脂肪酸酰胺多胺 ,用浓盐酸中和制得AY - 1型阳离子沥青乳化剂 ,加入计量的水配制成一定浓度的乳白色或淡黄色膏状物 经实验以 0 .5 - 1 .5 % (与沥青的配比 )用于沥青的乳化 ,可制成稳定的沥青乳液 该产品具有乳化能力强、用量少、价格低、生产工艺简单、质量稳定等优点 可作为一种新型阳离子沥青乳化剂 。

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.
