| 摘 要： | 合成了己二酸锌钙皂，并将纳米氧化铈和氧化镧分别作为共稳定剂制备了新型复合热稳定剂。采用刚果红法、热失重分析仪、动态力学分析仪等考查了复合热稳定剂对聚氯乙烯/丙烯酸酯苯乙烯丙烯腈接枝共聚物（PVC/ASA）共混材料的热稳定效果及动态力学性能。结果表明，稀土化合物作为共稳定剂可以提高己二酸锌钙皂对PVC/ASA共混材料的热稳定效果，氧化镧与己二酸锌钙皂的协同效果优于纳米氧化铈，而纳米氧化铈的加入可以提高材料的热变形温度。

Thermal Stabilization Effect of Zn/Ca Adipate with Nano-CeO2 or La2O3 on PVC/ASA Blend |
| |
| Abstract: | Nano-CeO2 or La2O3 was introduced into znic/calcium adipate system as a co-stabilizer for PVC/ASA blends. The thermal stbility of resultant PVC/ASA blends was investigated by Congo red method and thermogravimetric analysis. The dynamic mechanical properties were also investigated. It was found that the thermal stability of PVC/ASA blends was enhanced when the rare earth compounds were used. The synergistic effect of lanthanum oxide with metal soaps was better than that of nano-cerium oxide. Moreover, the thermal distortion temperature of the blends was increased when nano-cerium oxide was added. |
