摘　　要：为探究椰油酰甘氨酸钠(SCG)与两性表面活性剂复配体系的泡沫性能,对泡沫体积、泡沫半衰期、临界胶束浓度(cmc)、表面张力进行测试。结果显示SCG在硬水中,pH=8时,泡沫体积最大,半衰期最小,说明此条件下泡沫量和稳定性表现最好。在pH为8时,SCG复配不同质量比两性表面活性剂椰油酰胺丙基甜菜碱(F50)、椰油酰胺丙基羟基磺基甜菜碱(CHSB-35)、月桂酰两性基二乙酸二钠(MAB)、月桂酰两性基乙酸钠(LSH),结果在去离子水中质量比为SCG︰F50=20︰10时泡沫体积最大。SCG与两性表面活性剂在固定质量比20︰10下测试cmc、表面张力,当SCG与F50复配时cmc最小,说明与椰油酰胺丙基甜菜碱复配在低浓度下最容易有效发泡。The foam volume, foam half-life, critical micelle concentration(cmc) and surface tension was tested in order to investigate the foam properties of the compound systems of sodium coir glycine(SCG) and zwitterionic surfactants.The results showed that SCG had the largest foam volume and the smallest half-life when pH=8 in hard water, indicating the best foam volume and stability performance under this condition.When pH was 8, SCG was combined with zwitterionic surfactants such as Cocamidopropyl Betaine(F50), Cocamidopropyl Hydroxysulfobetaine(CHSB-35), Disodium Lauroamphodiacetate(MAB) and Sodium Lauroamphoacetate(LSH) with different mass ratios.The results showed that the foam volume reached the maximum when the mass ratio of SCG: F50=20:10 in deionized water.SCG and zwitterionic surfactants were tested at a fixed mass ratio of 20:10 to test cmc and surface tension.When SCG was combined with F50, cmc was the smallest indicating that was the most effective foamers at lower concentrations.
