摘要： 以腰果酚和甲醛为原料合成腰果酚醛树脂起始剂, 再与环氧乙烷( EO) 和环氧丙烷( P O) 聚合, 合成腰 果酚醛树脂嵌段聚醚破乳剂( C P F E) 。采用表面张力法测定了C P F E的临界胶束浓度( c m c) 为8 0m g / L, 对应的表 面张力值( γ c m c) 为1 7. 3 8mN /m。采用旋滴法测定了C P F E的油 - 水界面张力, 考察了C P F E质量浓度和温度对油 - 水 界面张力的影响。结果表明, 随着C P F E质量浓度增加, 油 - 水界面张力显著下降; 随着温度升高, C P F E的界面活性 下降, 表明C P F E适合在低温环境下使用。采用单滴法测定了油滴破裂速率常数k随C P F E质量浓度的增加而增 大。

Abstract: A cardanol phenolformaldehyde resin was synthesized using cardanol and formaldehyde as raw material, and the cardanol based phenolformaldehyde resin block polyether demulsifier (CPFE) was further synthesized using cardanol phenolformaldehyde resin as initiator through polymerization with epoxy propane (PO) and epoxyethane (EO), respectively. The crtical micelle concentration of CPFE was measured with the method of surface tension, and the results showed that the crtical micelle concentration of CPFE was 80 mg/L and the γcmc was 17.38 mN/m. The oilwater interfacial tension of CPFE was determined with a spinning drop tension meter. The influences of concentration and temperature on oilwater interfacial tensions were discussed in detail. Experimental results showed that the oilwater interfacial tension dereased obviously with the increase of concentration of CPFE, and the interfacial activity of CPFE dedined as temperature increased, which illustrated that the CPFE could be applied in low temperature environment. The oil droplet rupture constant k was measured by single droplet method, and the oil droplet rupture constant k increased with the increase of CPFE concentration. 
