| 摘 要： | 以己二异氰酸酯(HDI)、聚醚二醇(PTMG1000)、N-甲基二乙醇胺(N-MDEA)、苯乙烯(St)、丙烯酸丁酯(BA)和丙烯酸羟乙酯(HEA)等为主要原料制备了无溶剂阳离子型聚氨酯/丙烯酸酯(PUA)复合乳液,系统研究了HEA、MDEA以及丙烯酸树脂用量等对涂膜性能的影响,并通过红外光谱(FTIR)、热重分析(TGA)等对其进行了表征。实验结果表明,当w(HEA)=6%,w(MDEA)=6%,丙烯酸树脂质量分数为40%时,涂膜的性能达到最优。通过对阳离子水性聚氨酯/丙烯酸酯乳液涂膜性能的研究,在最佳聚合工艺的条件下,涂膜的吸水率为9.26%,拉伸强度为35.6MPa,断裂伸长率达到337%。

| Abstract: | The cationic Polyurethane/Polyacrylate composite emulsion was prepared by HDI, PTMG1000, N-MDEA, styrene (St), butylacrylate (BA), Hydroxyethyl acrylate (HEA). The effects of the content of HEA, MDEA, and Polyacrylate on performance of the films were investigated. And it was characterized by the method of IR, TGA. When w (HEA) = 6%, w (MDEA) = 6%, w(Polyacrylate)=40%, the coating can achieve the optimize performance. The results showed that water absorption was 9.26 %, the tensile strength was 35.6MPa, the elongation at break was 337%. |
