环保型超低含固率乳化糊的制备及其性能

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。

Preparation and characterization of an eco-friendly emulsion thickener with ultralow solid content

In order to improve the stiff hand feeling of the pigment printing and to overcome the oil pollution of the traditional kerosene emulsion thickener and the electrolyte sensitivity of the synthetic thickener, the new O/W and W/O emulsion thickener with the eco-friendly nonionic silicone and a certain proportion of water were prepared , and the influences of different emulsifiers or emulsifier combinations on the emulsion type, the viscosity and rheological property, the storage stability and the chemical compatibility of new emulsion thickeners were investigated. The experimental results showed that: the new emulsion thickener prepared with emulsifier combination could have the highest viscosity, the storage stability and the chemical compatibility of O/W emulsion thickener prepared with pure non-ionic emulsifier were the best; O/W emulsion thickener showed excellent application performance, with which, pigment printed silk sample could get super-soft hand feeling.
