| 摘 要： | 采用核壳结构种子乳液聚合法,以双丙酮丙烯酰胺(DAAM)和己二酸二酰肼(ADH)为交联单体,合成了具有良好耐水性的室温自交联核壳结构丙烯酸酯乳液;研究了交联单体的用量、交联温度、复合乳化剂用量及配比等对乳液性能的影响。FTIR测试证实了交联反应的发生;乳液的粒径图、DSC曲线和TEM表明,乳液具有2个玻璃化转变温度,具有明显的核壳结构。

| Abstract: | Taking diacetone acrylamide(DAAM)and hydrazide adipate(ADH)as the cross-linking monomers,the core-shell structure ambient self-cross-linking acrylic emulsion with good water-resistance was synthesized by core-shell structure seed emulsion polymerization method.The effects of the amount of cross-linking monomer,different cross-linking temperatures and the amount and ratio of compound emulsifier on emulsion properties were discussed.FTIR test confirmed the occurrence of cross-linking reaction;the emulsion par... |
