Abstract
A cationic Gemini surfactant containing bis -piperidinium group (hereinafter refers to as C10 -CGP)was synthesized via three steps with aniline,epichlorohydrin,piperidine and 1-bromodecane as starting materials. The product was characterized by FT-IR,MS and 1 H NMR. The Krafft point and emulsifying power of the product as well as performance of emulsified asphalt prepared with the product were examined. The critical micelle concentration (cmc)and corresponding surface tension (γcmc )of C10 -CGP were measured at temperature range from 25 ℃ to 40 ℃ and thermodynamic parameters of the micellization were calculated. Results show that the Krafft point of C10 -CGP is below 0 ℃;stable time of emulsified liquid achieves 532 s;the cmc andγcmc at 25℃ is 0. 976 × 10-3 mol/L and 28. 93 mN/m respectively. With the increase of temperature, the cmc increases,while the γcmc decreases,the maximum surface adsorption capacity (Γmax )decreases and the minimum molecule sectional area (Amin )increases. Emulsified asphalt test shows that C10 -CGP is a slow-crack type asphalt emulsifier;storage stability of the emulsified asphalt is good and particle size distribution of the emulsified asphalt is narrow.关键词
