烷基糖苷季铵盐表面活性剂复配性能研究

Study on compound properties of alkyl glycoside quaternary ammonium surfactant

将丁基葡萄糖苷、辛基葡萄糖苷分别与3-氯-2羟基丙基二甲基十二烷基铵盐、3-氯-2羟基丙基二甲基十六烷基铵盐按照摩尔比为1:1,1:0.5和1:0.1进行复配,并测定复配体系的表面张力、临界胶束浓度(cmc)、亲水亲油平衡值(HLB)、泡沫性能、去污性能及乳化性能。结果表明,辛基葡萄糖苷羟基丙基二甲基十二烷基铵盐酸盐类型样品和阴离子表面活性剂复配后性能良好;HLB值显示丁基葡糖苷羟基丙基二甲基十二烷基铵盐酸盐样品的表面活性和亲水性较好;当丁基葡萄糖苷和辛基葡萄糖苷质量分数为80%时,丁基葡萄糖苷羟基丙基二甲基十六烷基铵盐酸盐泡沫性能、乳化性能和稳定性均较佳;丁基葡萄糖苷羟基丙基二甲基十六烷基铵盐酸盐复配体系对碳黑污布和蛋白污布去污效果较好。

The butylglucoside and octylglucoside were compounded with 3-chloro-2-hydroxypropyl dimethyl dodecylamine salt and 3-chloro-2-hydroxypropyl dimethyl hexadecyl salt according to the molar ratio of 1∶1,1∶0.5 and 1∶0.1.The surface tension,critical micelle concentration(cmc),hydrophile-lipophile balance(HLB),foam property,detersive performance and emulsifying property of the complex system were also determined.The results show that the performance of octylglucoside hydroxypropyl dimethyl dodecylammonium hydrochloride compounded with anionic surfactant is good.The surface activity and hydrophilicity of butylglucoside hydroxypropyl dimethyl dodecyl ammonium hydrochloride samples are good.When the mass fraction of butylglucoside and octylglucoside was 80%,the foam properties,emulsification properties and stability of butylglucoside hydroxypropyl dimethyl hexadecyl ammonium hydrochloride were all in good condition.The decontamination performance of butylglucoside hydroxypropyl dimethyl hexadecyl ammonium hydrochloride compound system is good for carbon black cloth and protein stain cloth.
