| 摘 要： | 分别研究了皂/硫磺、硫磺/DCP/促进剂、3#硫化剂/硫磺/促进剂3种硫化体系用于硫化金属密封垫片的丁腈(NBR)与丙烯酸酯(ACM)并用胶时,硫化体系及硫化剂用量对涂层表观性能、力学性能、耐热老化性能、耐液体性能的影响。结果表明:3#硫化剂/硫磺/促进剂硫化体系硫化的NBR/ACM并用胶的综合性能优于皂/硫磺和硫磺/DCP/促进剂硫化体系,当3#硫化剂用量为5 g时,NBR/ACM并用胶具有较好的机械性能、耐热空气老化性能和耐液体性能。 |

| Abstract: | The nitrile rubber(NBR) and acrylic rubber(ACM) blends used as metal sealing gaskets were cured by soap/sulfur,sulfur/DCP/accelerator and 3# curing agent/sulfur/accelerator,respectively.The effects of the three curing systems and the dosage of curing agent with NBR and ACM on the basic properties of coating,the mechanical properties and heat resistance,oil resistance and liquid resistance of vulcanizate were investigated.The results showed that the NBR and ACM blends cured by 3# curing agent/sulfur/accelerator had better over-all properties than that of cured by soap/sulfur and sulfur/DCP/accelerator systems.When the content of 3# curing agent was 5 g,the NBR and ACM blends had better mechanical properties of heat resistance,oil resistance and liquid resistance. |
| Keywords: | curing systems nitrile rubber(NBR) acrylic rubber(ACM) gasket seal coating |
