Synthesis of aliphatic alcohol polyoxyethylene ether AEO-9 type surfactant
The invention provides synthesis of a Gemini type cationic asphalt emulsifier--1,3-{N-[3-dodecyloxy polyoxyethylene ether(9)-2-hydroxy]propyl dimethyl}propane from aliphatic polyoxyethylene ether AEO-9, epichlorohydrin, dimethylamine and 1,3-dibromopropane. The Gemini type cationic asphalt emulsifier is used for preparing emulsified asphalt. The test results of the emulsified asphalt show that the prepared emulsified asphalt can be stably stored for 5 days when the usage amount of the emulsifier is 2.5% of the total amount of the emulsified asphalt. The Gemini type cationic asphalt emulsifier provided by the invention can be extensively applied to adhesive bonding layers, fog sealing layers and solvent-free cold mixing, and is used for recycling of asphalt and stabilization of a asphalt pavement base.
