活性染料印花用合成增稠剂的合成与配方研究

文档编号:CL053  文档字数:13174,页数:28

 摘 要：涂料印花的印制效果和质量很大程度上取决于印花色浆组成及性能，其中增稠剂起着关键的作用。本人采用反相乳液聚合法，将中和的丙烯酸和N，N’-亚甲基双丙烯酰胺水溶液，借助乳化剂和搅拌作用，将其分散于非极性有机溶剂中，形成油包水型(W/O)乳液，进而聚合合成涂料印花增稠剂LG-301。通过对中和液pH值、交联剂、引发剂、聚合温度和通氮气等合成因素探讨和合成增稠剂应用性能研究，用该方法增稠剂印制的涂料印花织物，具有得色量高、花纹轮廓清晰、手感好等优点。综述了国内外活性染料印花糊料的发展现状并讨论了台成增稠剂在改善耐电解质性能和手感方面的有关理论研究。通过丙烯酸和脂肪醇聚氧乙烯醚类表面活性剂反应合成水溶性长链疏水单体，该单体通过反相乳液聚合法和丙烯酸共聚，得到耐电解质性能较好的疏水缔合型聚丙烯酸盐增稠剂。

Abstract: Pigment printing and quality printing results depends largely on the composition and performance of printing paste, which play a key role thickener. I am using reversed-phase suspension polymerization, will be in and of acrylic acid and MBAM aqueous solution, mixing with the role of emulsifier and its dispersion in the non-polar organic solvents to form a water-oil type (W / O) emulsion, Synthetic polymer to pigment printing thickenerLG-301. And solution of pH, cross-linker agent, initiator, polymerization temperature and nitrogen pass factors of synthetic thickener and synthetic application performance study, using the method of the pigment printing thickener printed fabric, with a yield high, a clear outline of the pattern, feel good and so on. Summary of reactive printing paste at home and abroad of the status quo and discussed the development of Taiwan into a thickening agent to improve the performance and feel resistant electrolyte relevant theoretical research. Water—solhydrophobic long—chain monomers were synthesized by the reaction of acrylic acid with surfactants of fatty alc.polyoxyethylene ethers,and were copolymerized with acrylic acid by the inverse emulsion polymn to give hydrophobic associative polyacrylic acid thickeners with good electrolyte resistance.
