| Abstract: | Synthesis of a kind of cationic asphalt emulsifier-lignin-amine was based on the Mannich reaction of lignin with formaldehyde and tetraethylene pentamine.The conductivity-titration method was introduced to analyze the product,the optimized technological conditions were as follows:the reaction temperature was(85±0.5)℃,the quality ratio of formaldehyde to TEPA was 3.9∶1,reaction time was 3 h,quality of lignin was 31 g.The emulsification result showed that this lignin-amine could be an effective cationic asphalt emulsifier. |
