酮肼交联体系核壳丙烯酸树脂乳液的制备及涂膜性能研究

Synthesis and Characterization Research of keto-hydrazine Crosslinking core-shell structure Acrylate Emulsion

摘要:

以双丙酮丙烯酰胺（DMMA）和已二酸二酰肼（ADH）为交联体糸，采用核壳结构种子乳液聚合法，合成了室温自交联的核壳丙烯酸树脂乳液。主要研究了交联体系在乳胶粒子的核层和壳层的用量对膜性能的影响，FTIR测试证实无论在核层还是壳层均能发生DMMA-ADH这种交联发应。通过TEM分析显示这种室温自交联的丙烯酸树脂乳液图具有明显的核壳结构。

Abstract:

The core–shell structure ambient self-cross-linking acrylic emulsion was synthesized by core-shell structure seed emulsion polymerization method. Diacetone acrylamide（DAAM）and hydrazide adipate（ADH）were used as cross-linking monomers. Influence of different addition methods and different amount of DMMA-ADH on film properties were investigated. FTIR test confirmed that cross-linking reaction can be occurred when DMMA-ADH was introduced into the core or the shell. In this study, DMMA-ADH was introduced into the core and the shell of latex particles. The clear core-shell structure was characterized by TEM.
