通过阳离子交换制备三聚氰胺改性蒙脱石（MA-MMT）。通过傅里叶变换红外光谱仪（FT-IR）、X射线光电子能谱（XPS）和X射线衍射（XRD）研究了插层行为。结果表明，d-间距值从Na-蒙脱土(Na+MMT)的1.25 nm增加到MA-MMT的1.53 nm。采用不同种类的蒙脱石与三聚氰胺焦磷酸盐（MPP）结合制备阻燃聚酰胺6（FR-PA6）。通过极限氧指数(LOI)、UL-94垂直燃烧法和锥形量热仪测试研究了FR-PA6样品的阻燃性能。通过扫描电子显微镜（SEM）和XPS研究了FR-PA6残炭的形貌和成分。结果发现，MA-MMT/MPP体系为PA6提供了优异的阻燃性和抗滴落能力。 MA-MMT颗粒可以填充炭残留物的缺陷并强化炭层，从而形成更多的膨胀炭层。聚合物。 ENG。 SCI., 51:377385, 2011。(C) 2010 年塑料工程师协会
Melamine-modified montmorillonite (MA-MMT) was prepared via cation exchange. The intercalation behavior was investigated by Fourier transform infrared spectrometer (FT-IR), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD). The results showed that the d-spacing value increased from 1.25 nm for Na-montmorillonite (Na+MMT) to 1.53 nm for MA-MMT. Different kinds of montmorillonite combined with melamine pyrophosphate (MPP) were used to prepare flame-retardant polyamide 6 (FR-PA6). Flame retardance of FR-PA6 samples was investigated by limiting oxygen index (LOI), UL-94 vertical burning method, and cone calorimeter test. Morphology and component of char residues for FR-PA6 were investigated by scanning electron microscope (SEM) and XPS. It was found that MA-MMT/MPP system contributed both excellent flame retardance and anti-dripping ability for PA6. MA-MMT particles can fill flaws of char residues and strengthen the char layer, leading to form more intumescent char layer. POLYM. ENG. SCI., 51:377385, 2011. (C) 2010 Society of Plastics Engineers
