摘要： 研究了N-十二烷基-N,N-二甲基-N-苄磺基甜菜碱(DBSB)作为代磷助剂的性能。结果表明,DBSB的钙皂分散指数为3%,与十二烷基苯磺酸钠(LAS)二元复配后,可提高复配体系的钙离子稳定性,当DBSB占二元体系的质量分数为15%时,体系承受的钙离子浓度从5 mmol·L-1升高到30 mmol·L-1。以DBSB替代4A沸石加入到无磷模拟洗衣粉配方中,可保持较好的去污力,且DBSB的加入可大幅度提高配方的抗硬水性能。通过正交试验得到优化配方5,其在250和400 mg·L-1硬水中的去污力均优于4A沸石无磷模拟配方(配方6),且灰分残留量较少,具有低泡性,pH、总活性物含量及游离碱含量符合国标要求。

Abstract: Properties of N-dodecyl-N,N-dimethyl-N-benzyl sulfobetaine (DBSB) as a phosphate-free detergent builder to replace 4A zeolite were investigated.Results showed that lime soap dispersion power (LSDP) of DBSB achieves 3%.When LAS is blended with DBSB,its calcium tolerance is enhanced.In case the mass fraction of DBSB in the blend system of LAS and DBSB achieves 15%,its calcium tolerance can be elevated from 5 mmol·L-1 to 30 mmol·L-1.Formulating DBSB into standard phosphate-free laundry powder to replace 4A zeolite will retain its good detergency with significant improvement of resistance to hard water.Via orthogonal designed experiments,an optimized formulation 5 was recommended that shows better detergency in water with hardness of 250 and 400 mg·L-1 as comparing with 4A zeolite formulated phosphate-free laundry powder formulation 6.In addition,residual ash content caused from the laundry powder formulation 5 is lower than that from formulation 6;the DBSB formulated product displays lower foam with all other specifications,such as pH,total active matter content and free alkalinity in conformity with that specified in the China national standard.

Key words: dodecyl benzyl sulfobetaine, phosphate-free detergent builder, hard water resistance, phosphate-free laundry powder
