摘要： 以工业一级对壬基酚(简称NP)与二乙醇胺为原料合成了1种阳离子沥青乳化剂,4种两性沥青乳化剂.通过红外光谱分析验证了最终产物的结构;采用化学滴定法测定了反应产物的有效成分含量.利用合成的沥青乳化剂制备出乳化沥青,并对乳化沥青的乳化效果、储存稳定性、拌和稳定度、标准黏度、沥青含量、筛上残留物、与粗集料的裹附性等项目进行了测试.结果表明,4种沥青乳化剂的乳化效果较好,其中1种可以作为中裂型沥青乳化剂使用,另外3种可以作为慢裂型沥青乳化剂使用.

Abstract: Nonylphenol (NP for short) and diethanolamine were used as raw materials to synthesize one cationic and four amphoteric asphalt emulsifiers. The structure of emulsifiers was investigated by FT-IR. The effective content of reaction products was determined by chemical titration. Emulsifiers synthesized were used for preparing emulsified asphalt. The performance was tested, including emulsifying effectiveness, storage stability, mixing stability, normal viscosities, asphalt content, residues on screening and the property of wrapping coarse aggregate. The results demonstrated that the four emulsifiers have good properties. One of them can be used as a moderate-setting asphalt emulsifier; the others can be used as slow-setting asphalt emulsifiers.
