| 中文摘要: |
| 研究填料种类对不同硫化体系药用聚异戊二烯橡胶（IR）胶料及制品性能的影响。结果表明：在过氧化物硫化体系胶料中，填料的酸碱性对胶料的硫化特性有明显影响，使用碱性填料滑石粉Mistron CB、碱性白炭黑MG和改性煅烧高岭土Burgess 2211的胶料交联密度明显高于使用酸性填料煅烧高岭土的胶料；在硫黄硫化体系胶料中，使用碱性填料改性滑石粉Mistron CB和改性煅烧高岭土Burgess 2211的胶料交联度与使用酸性填料煅烧高岭土的胶料没有明显差异；单独使用沉淀法白炭黑VN3，胶料的变形大，胶料没有实际应用意义；药用IR胶料中优先采用过氧化物硫化体系，优化并用不同酸碱性填料，采用高温（175~185 ℃）硫化，制品具有优异的抗臭氧分解性能、耐灭菌性和耐老化性能等。 |
| 英文摘要: |
| In this study，the influence of different fillers on the properties of medical IR compounds and products was investigated.The experimental testing results showed that in peroxide cured compounds，the acidity or basicity of the filler showed significant influence on the curing characteristics.The compounds filled with alkaline filler talc Mistron CB，alkaline silica or modified calcined kaolin Burgess 2211 achieved a much higher crosslink degree than the compounds filled with acidic calcined kaolin.In sulfur cured compounds，the crosslink degree didn’t show much difference among using different fillers.When the compound was filled with only precipitated silica VN3，it showed large deformation and had no practical use.The medical IR rubber products were usually cured using peroxide at high temperature (175~185 ?C)，with optimized filler combination to achieve excellent ozone resistance，sterilization property and anti-aging properties. |
