摘　　要：针对颜料印花手感不佳以及传统乳化糊的火油污染和合成增稠剂的电解质、pH值敏感问题,用非离子环保型特种化合物MCSO-510与水在一定比例下乳化,制得超低含固率的O/W型和W/O型乳化糊,研究了不同乳化剂和乳化剂复合体系对新型乳化糊成糊类型的影响,考察了新型乳化糊的黏度与流变特性、久置稳定性、与化学药剂的相容性以及部分应用性能。结果表明:采用复合乳化剂制备的乳化糊具有较高的黏度,单纯的非离子型乳化剂制备的O/W型乳化糊的久置稳定性以及与染化药剂的相容性最好;采用O/W型乳化糊印制的丝绸颜料印花产品可获得超柔软手感和优良的色牢度。In order to improve the stiff hand feeling of pigment printing and overcome the oil pollution of traditional kerosene emulsion thickeners and electrolyte sensitivity of synthetic thickeners,novel O /W and W /O emulsion thickeners with ultralow solid content were prepared with special eco-friendly nonionic chemical MCSO-510 and a certain proportion of water.The impacts of different emulsifiers or emulsifier combinations on emulsion type,and viscosity,rheological property,storage stability and chemical compatibility of the novel emulsion thickeners were investigated.The experimental results showed that the emulsion thickener prepared with emulsifier combinations had higher viscosity than others,and the O /W emulsion thickener prepared with pure nonionic emulsifier had the best storage stability and chemical compatibility.The O /W emulsion thickener showed excellent application performance,with which,pigment printed silk displayed super-soft hand feeling and good color fastness.
