| 中文摘要: |
| 研究4种环保型增塑剂TOTM（偏苯三酸三辛酯），BXA-N{己二酸二[2-（2-丁氧基乙氧基）乙酯]}，A-8000（己二酸聚酯）和TP-759（聚醚和聚酯的混合物）对丁腈橡胶（NBR）/聚氯乙烯（PVC）共混胶性能的影响。结果表明：增塑剂的相对分子质量和分子结构是影响NBR/PVC共混胶性能的主要因素；添加增塑剂TOTM和A-8000的硫化胶物理性能较好；添加增塑剂BXA-N和TP-759的硫化胶更耐IRM903#油和燃油C的渗入，在燃油C中浸泡后物理性能变化更小；添加增塑剂A-8000的硫化胶的耐压缩永久变形性能和耐热空气老化性能较好。在4种环保型增塑剂中，增塑剂A-8000更适用于NBR/PVC共混胶。 |
| 英文摘要: |
| The effects of four environment-friendly plasticizers，TOTM（trioctyl metabenzoate），BXA-N{adipate di-[2-（2-butoxyethoxy）ethyl]}，A-8000（adipate polyester） and TP-759（mixture of polyether and polyester） on the properties of NBR/PVC blends were studied.The results showed that the relative molecular weight and molecular structure of plasticizers were the main factors affecting the properties of NBR/PVC blends.By adding plasticizer TOTM or A-8000，the physical properties of vulcanizates with were improved，the vulcanizate had good resistance to IRM903# oil and fuel C，and the change of physical properties was smaller after soaking in fuel C.The compression set of vulcanizates with plasticizer A-8000 was lower and the heat aging resistance were better.Plasticizer A-8000 was more suitable for NBR/PVC blends than other three environment-friendly plasticizers. |
