| 摘 要： | 采用原位乳液聚合法制备了聚甲基丙烯酸甲酯(PMMA)／三聚氰胺氰尿酸盐(MC)复合胶粒，对其进行X光电子能谱及热重分析结果显示，在MC阻燃剂颗粒表面覆盖了一层PMMA胶膜，形成了具有核-壳结构的PMMA／MC复合胶粒；MC能影响PMMA的热降解过程并促进其成炭；在尼龙6(PA6)中的应用结果表明，PMMA／MC复合胶粒能改善PA6的力学性能和阻燃性能。

| Abstract: | Poly(methyl methacrylate)(PMMA)/melamine cyanurate(MC) composite latex particles are prepared via soapless emulsion polymerization. XPS data and TGA analysis reveal that MC particles are encapsulated by PMMA during polymerization, resulting in the formation of a core-shell structure of PMMA/MC composite latex particles. MC can affect the thermal degradation and promote the charring of PMMA. The application of PMMA/MC in nylon 6 (PA6) indicate that the composite latex particles can improve the mechanical properties and flame retardance of PA6. |
