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OA北大核心
Preparation,thermal stability and antibacterial properties of pentaerythritol fumarate-based lanthanum rare earth compounds for use in PVC
本文以富马酸、季戊四醇和醋酸镧为原料,合成了富马酸季戊四醇镧(FGPE-La)稀土化合物,对其结构和组成进行了表征,并研究了FGPE-La在聚氯乙烯(PVC)中的热稳定性能和抗菌性能.结果表明,FGPE-La是兼具热稳定性能和抗菌性能的多功能PVC助剂,当FGPE-La∶ZnSt2=3∶1时,具有较好的初期白度和长期热稳定性,且当4份FG-PE-La单独使用时,热稳定时间达到了68 min,能够显著提高PVC的长期稳定性;当添加6%(质量分数,下同)FGPE-La时,PVC的抑菌率达到99.1%,溶血率也仅为4.6%,具有较好的生物相容性.
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.
