富马酸季戊四醇酯基镧稀土化合物的制备及其在PVC中热稳定性能和抗菌性能的研究
Preparation,thermal stability and antibacterial properties of pentaerythritol fumarate-based lanthanum rare earth compounds for use in PVC
摘要
Abstract
A rare earth compound,fumaric acid pentaerythritol lanthanum(FGPE-La),was synthesized using fumaric ac-id,pentaerythritol,and lanthanum acetate as raw materials.The chemical structure and composition of the resultant FG-PE-La were characterized,and its thermal stability and antibacterial properties when used in PVC were investigated.The results indicated that FGPE-La could be used as a multifunctional PVC additive with both good thermal stability and antibacterial properties.When a mixer of FGPE-La and ZnSt2 at a mass ratio of 3:1 was used for PVC,good initial whiteness and long-term thermal stability could be obtained in the modified PVC.Moreover,the thermal stability time of the modified PVC reaches 68 minutes when 4 phr FGPE-La was incorporated alone,indicating a significant improvement in the long-term stability.An antibacterial rate of 99.1%was achieved for the modified PVC containing 6 wt.%FGPE-La,and its hemolysis rate was only 4.6%,indicating good biocompatibility.关键词
