| 摘 要： | 目的：对比SY－1和MDX4－4210硅橡胶的吸水率，溶解率，撕裂强度性能。方法：在相同条件下对两种硅橡胶材料进行吸水率，溶解率及撕裂强度测定，对其进行t检验分析。结果：SY－1硅橡胶吸水率，溶解率性能差于MDX4－4210硅橡胶，撕裂强度优于MDX4－4210硅橡胶。结论：SY－1硅橡胶的撕裂强度符合作为颌面部软组织缺损的赝复材料要求；作为与液体有密切接触的赝复材料时，其吸水率，溶解率性能尚须进一步改进。 |
| 关 键 词： | 硅橡胶 吸水率 溶解率 撕裂强度 |

| Abstract: | Objective: To compare the water sorption, the water solubility and the tear strength of SY-1 and MDX4-4210 silicon rubber. Methods: The water sorption, the water solubility and the tear strength of two kinds of silicon rubbers were examined and evaluated under the same conditions. Results: The tear strength of SY-1 silicon rubber was better than that of MDX4-4210 silicon rubber. The water sorption and solubility were inferior to that of MDX4-4210 silicon rubber. Conclusions: The tear strength of SY-1 silicon rubber could be satisfied the demand of prosthestic materials for the maxillofacial soft tissue defect. But the water sorption and solubility should be improved as the prosthestic materials that often contacts with water. |
