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 10 0 ;NBR 2 5 ;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。
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 formula 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.
