摘要: 采用研磨分散法制备了超细分散染料红60,研究了聚苯乙烯马来酸酯化物(PSMA)和脂肪醇聚氧乙烯醚(AE)协同作用对分散染料分散稳定性能的影响。结果表明:采用PSMA制备超细分散染料的粒径为207nm,而采用PSMA与AE复配分散剂,在相同条件下制备超细分散染料的粒径为166nm,且分散速率常数从-2.88提高到了-3.48。性能对比发现,采用PSMA/AE复配制备的超细分散染料热稳定性较PSMA提高了6%,离心稳定性提高了4%。对涤纶织物染色发现,PSMA/AE复配制备的超细分散染料的染色速度和匀染效果明显优于PSMA制备的超细分散染料。

Abstract: The ultrafine disperse dye red 60 was prepared by milling method,and then investigated the effect of dispersion stability of disperse dye on synergistic effect of polystyrene maleic esterified esters (PSMA) and fatty alcohol polyoxyethylene ether(AE). The results showed that the particle size of ultrafine disperse dye was 230nm when using PSMA, whereas the particle size of disperse dye was about 174 nm, and disperse rate constant increased from -2.88 to -3.48 by using PSMA and AE formulated dispersants under the same conditions. The performance comparisons showed that using the mixture of PSMA/AE dispersant, its thermal stability increased by 6 % and centrifugal stability increased by 4 %. It was found that the dyeing speed and levelling effects of ultrafine disperse dye that prepared by PSMA/AE formulated dispersants were obviously superior to the one prepared by PSMA when dyeing polyester fabric.
