| Abstract: | The synthesis and application of SM-cationic asphalt emulsifier,imidazoline chlorideused in highway construction are presented.The raw materials used are fatty acid and amine.The reaction consists of three steps:condensation(140一180℃,1.0一1.5h),cyclization(180一250℃,1.5一2.0h)and quaterisation(80℃).The stable and effective emulsifier canbe obtained with or without solvent.Experiments have been carried out on enlarged scale. Inapplication,the optimal conditions are:ratio of asphalt to water, 60:40;pH,2.5一5.5;emulsifier,0.25%一0.40%,The technical indices shown in the 350m highway built inXianyang in 1989 proved that the quality of the emulsifier and elliulsion was in conformitywith that specified in the relevant Technical Standards of the Chinese Ministry of Communication. |
