摘要/Abstract

摘要： 目的: 利用杜仲胶的优良特性,制备新型高弹性杜仲胶复合义齿软衬材料,通过配方设计和筛选获得符合口腔临床应用的相应特性。方法: 参考现有弹性杜仲胶配方和医用橡胶配方,结合口腔临床要求,以硬度、拉伸强度和断裂伸长率为力学性能观察指标,调整橡胶基质配比和气相白炭黑的用量,确定性能配方;对按照该配方制备的样品进行力学性能测试,并根据结果对配方修改,直至获得适宜的杜仲胶复合义齿软衬材料配方。结果: 当杜仲胶与顺丁橡胶共混比例为80∶20,气相白炭黑的用量在7PHR时,适量添加部分助剂,杜仲胶复合义齿软衬材料可获得适宜口腔临床应用的力学性能。结论: 通过配方调试获得了杜仲胶复合义齿软衬材料的最终性能配方,效果比较理想。

Abstract: Objective: To prepare a soft lining material with high elastic on the basis of excellent characteristics of eucommia ulmoides gum. Methods: The basic formula was used based on the existing formula of elastic eucommia ulmoides gum and medical rubber. The current formula was modified according to the specific requirements of denture lining materials. Corresponding eucommia ulmoides gum composite soft denture liners were constructed and delivered to physical and mechanical property tests. Subsequent modification to the formula was made according to the results of tests. The "modification and test" procedure was repeated, until favorite formula was established. Results: When eucommia ulmoides gum and butadiene rubber blend ratio was 80∶20, after adding gas phase nano-silica with 7PHR and appropriate content of fillers, eucommia ulmoides gum composite soft denture liners could present favorite properties. Conclusion: The final formula of eucommia ulmoides gum composite soft denture lining material was established by the "modification and test" procedure.
