| 摘 要： | 采用阴离子自乳化法合成了聚氨酯分子侧链上含聚二甲基硅氧烷（PDMS）的改性水性聚氨酯-丙烯酸酯系列复合乳液（SiPUA），主要探讨了氨乙基氨丙基聚二甲基硅氧烷（AEAPS）含量对SiPUA乳液及其涂膜性能的影响．结果表明，AEAPS在SiPUA中质量分数为6％时，乳液稳定性良好；涂膜的吸水率明显降低，断裂伸长率增加，但拉伸强度有所减小．

| Abstract: | A series of modified waterborne polyurethane-acrylate hybrid emulsion （SiPUA） containing PDMS side chains in PU were synthesized using anionic self-emulsion method. The effect of aminoethylaminopropyl polydimethylsiloxane （AEAPS） content on properties of SiPUA emulsion and film from SiPUA emulsion were investigated chiefly. The results show that when AEAPS contents in the SiPUA reach to 6%,the SiPUA emulsion has good stability,water absorption ratio and tensile strength of the film decrease ,but elongation at break increases. |
