| 中文摘要: |
| 研究用NBR改善NR/PVC共混物的耐油性能，通过测试所设计的各配方共混物的拉伸强度、扯断伸长率、硬度、耐磨性和耐油性等性能，得出NBR改性NR/PVC共混体系的最佳配比关系。最佳配方为：PVC 30；NR 100；NBR 25；硫黄 3；促进剂TMTD 0.8；促进剂D 1.5；促进剂DM 1.5；白炭黑 40；轻质碳酸钙 30；氧化锌 5；硬脂酸 1.5；防老剂D 2。共混物的耐油性能可达到NBR制品的要求。 |
| 英文摘要: |
| The oil resistance of NR/PVC blend was improved with NBR.The optimum blending ratio of NR/PVC/NBR was obtained by measuring the properties of test compounds，such as tensile strength，elongation at break，hardness，abrasion resistance and oil resistance.The optimum fo rmula was as follows：PVC 30；NR 100；NBR 25；sulfur 3；accelerator TMTD 0.8；accelerator D 1.5；accelerator DM 1.5；silica 40；light calcium carbonate 30；zinc oxide 5；stearic acid 1.5；antioxidant D 2.The oil resistance of the test blend was comparable to that of NBR product. |
