摘要/Abstract

摘要： 以脂肪胺聚氧乙烯醚(PAE)替换部分聚己二酸新戊二醇酯(POL7112)为软段,甲苯-2,4-二异氰酸酯(TDI)为硬段,合成了系列侧链含长链烷基与主链嵌入聚醚结构(EO)的阳离子聚氨酯乳液。通过红外(FTIR)、粒径、力学性能、热重分析(TGA)、吸水率及接触角等测试对乳液及胶膜进行分析。研究发现,在PU大分子中引入PAE,热稳定性明显提高;当PAE烷基碳链增长,断裂伸长率显著增大,拉伸强度有所减小;随着PAE用量的增加及其分子中EO加合度的增大,乳液粒径变小,稳定性增强,胶膜的亲水性显著提高。

Abstract: A series of PAE-based cationic waterborne polyurethane with long side chain alkyl group and the structure of polyether (EO) embedded in main chain were designed and synthesized based on poly(neopentylglycol adipate) (POL7112), PAE and TDI. The properties of emulsion and film were measured by infrared spectroscopy (FTIR), laser-particle size analyzer, tensile mechanical analyzer, thermogravimetry analyses (TGA) and contact angle analysis. Improved thermal stability of WPU-PAE could be attributed to the incorporation of PAE in PU. With increasing alkyl carbon chain of PAE, elongation at break of film increased remarkably while tensile strength reduced. Emulsion particle size decreased, emulsion stability was enhanced, hydrophilicity of film was improved remarkably with increasing quantity of EO and dosage in PEA.

Key words: polyoxyethylene alkyl amine, cationic waterborne polyurethane, poly(neopentylglycol adipate), TDI
