一种酰胺类沥青乳化剂的制备及性能研究
|
摘要
首先通过脂肪酸与酸酐反应,得到多元羧酸中间体,再将其与改性多乙烯多胺经过一系列反应合成一种酰胺类沥青乳化剂,采用傅里叶变换红外光谱对乳化剂结构进行表征。实验室对比测试了自制乳化剂与进口乳化剂的表面活性及其所制乳化沥青的性能。结果表明:采用两种乳化剂制备的乳化沥青的各项性能指标均可满足微表处施工技术要求,且自制乳化剂具有较高的固含量和较好的储存稳定性,乳化沥青8 min即可破乳,用于微表处养护可快速开放交通;自制乳化剂价格仅为进口乳化剂的76.4%左右,应用前景良好。
Polycarboxylic acid was obtained by the reaction of fatty acid with anhydride,and then an amide asphalt emulsifier was synthesized by reaction of modified polyethylene polyamine and polycarboxylic acid,and the emulsifier was characterized by Fourier transformation infrared spectroscopy.The laboratory tests showed that the performances of the emulsified asphalt prepared by the self-made emulsifier and the imported emulsifier could meet the technical criterion,and the self-made emulsifier had high solid content and storage stability,and the demulsification time was 8 min,which was beneficial to shorten the traffic control time during micro-surface maintenance.In addition,the cost of the self-made emulsifier is only about 76.4% of the price of the imported emulsifier.
