硬脂酸钙-硬脂酸锌复合物的形成及对聚氯乙烯的稳定化作用
If LDHs compounded with CaSt_2 and ZnSt_2,the thermal stability of PVC could be improved greatly,so as the synergistic effect.
分析了纳米水滑石(LDHs)对硬聚氯乙烯(UPVC)热稳定性的影响机理;并通过静态热稳定性实验发现,单纯使用LDHs作为聚氯乙烯的热稳定剂效果不好,初期稳定性较差,为此进行了正交实验设计,将LDHs与硬脂酸钙、硬脂酸锌复配,研究了这种复合稳定剂对聚氯乙烯动态热稳定时间的影响。
Effect of pentacrythritol complex with ZnSt_2, ZnCl_2 and the structural changes of PVC blend with ZnSt_2, Pe at 170 ℃ were studied by the fluorescence emission spectra, the fourier-transform infra-red spectra and the X-ray photoelectron spectroscopy.
通过荧光发射光谱、红外光谱和光电子能谱研究了季戊四醇与硬脂酸锌和氯化锌的络合作用,以及聚氯乙烯/ZnSt2/季戊四醇体系在170℃共混过程中的结构变化,结果表明,季戊四醇与硬脂酸锌和氯化锌形成络合物,在加工过程中无游离的氯化锌生成,季戊四醇与氯化锌形成的络合物抑制了氯化锌对聚氯乙烯的催化降解,从而抑制了"锌烧"。
