中文摘要:
      对混有不同填料的杜仲橡胶及填料界面结合胶进行了差示扫描量热法(DSC)分析及红外光谱检测。结果表明，填料对杜仲橡胶基质的结晶行为有明显影响，而且填料界面结合胶的DSC行为与杜仲橡胶基质有明显不同。杜仲橡胶基质相的DSC 曲线由于受填料影响，结晶温度及结晶热焓出现明显下移，但仍表现出典型结晶熔融特性；填料界面结合胶的DSC图谱已不再呈现典型峰型熔融特性，而呈现宽温度分布的、有吸热特性的包络线。
英文摘要:
      The gutta-percha rubber filled with various fillers and the bound rubber on the filler surface were investigated by differential scanning calorimetry(DSC) and infra-red spectrum(IR).Based on the results of DSC，we found not only the distinct effect of filler variety on the crystallization of gutta-perchar rubber matrix，but also obviously different DSC results between bound rubber and rubber matrix.Due to the effect of fillers，the filled gutta-percha rubber matrixs crystallization temperature and enthalpy shifted obviously downwards in DSC curves，but DSC curves still behaved as a typical characteristics of crystallization and fusion.On the contrary，in bound rubbers DSC curves，we observed the non-typical，broad distributive endothermal peak.
