一种双阳离子单阴离子叔酰胺型沥青乳化剂及其制备方法
摘要：
本发明公开一种双阳离子单阴离子叔酰胺型沥青乳化剂及其制备方法，该沥青乳化剂是由以下摩尔配比的原料制备而成：十八胺、醇类溶剂、N,N‑二甲基丙烯酰胺、低碳数叔胺、工业盐酸、环氧氯丙烷、氯乙酸钠的摩尔比为1mol：(4.00‑9.00)mol：(1.00‑1.08)mol：(1.02‑1.10)mol：(1.02‑1.10)mol：(1.02‑1.08)mol：(1.02‑1.10)mol。本发明在制备的沥青乳化剂的分子结构中通过加入N,N‑二甲基丙烯酰胺引入了酰胺基团，形成了双阳离子单阴离子叔酰胺型沥青乳化剂，增加了沥青乳化剂的亲水性以及乳化剂与沥青的相容性。
摘要（英）：

The invention discloses a dicationic and monoanionic tertiary amide asphalt emulsifier and a preparation method thereof. The asphalt emulsifier is prepared from the following raw materials of octadecylamine, an alcohol solvent, N,N-dimethylacrylamide, low-carbon tertiary amine, industrial hydrochloric acid, epoxy chloropropane and sodium chloroacetate at the molar ratio of 1mol:(4.00-9.00)mol:(1.00-1.08)mol:(1.02-1.10)mol:(1.02-1.10)mol:(1.02-1.08)mol:(1.02-1.10)mol. An amide group is introduced into a molecular structure of the prepared asphalt emulsifier through adding N,N-dimethylacrylamide to form the dicationic and monoanionic tertiary amide asphalt emulsifier, so that the hydrophilicity of the asphalt emulsifier and the compatibility of the emulsifier and asphalt are improved.
