摘　　要：在一般阻隔模型的基础上,推导出了一个能全面反映填料用量、结构、分散形态和填料圈闭等影响因素的数学阻隔模型,并在高岭土/天然橡胶复合材料体系中进行了验证,评价了该阻隔模型的准确性。另外,对不同结构类型填料的阻隔贡献也用相应的数学模型进行了对比研究。结果显示,修正的阻隔模型可直观的解释实验现象和结果,准确描述了填料结构类型和填料特性对聚合物复合材料的阻隔贡献。A mathematical model,which can fully reflect the influence of filler content,structure,dispersion shape and filler trap on gas barrier properties was deduced based on the general barrier model,and its accuracy was verified in kaolin/natural rubber composites.In addition,the barrier contribution of fillers with different structure types was contrasted by the corresponding mathematical model.The results showed that the modified model can intuitively interpret the experimental phenomena,and accurately describe the barrier contribution of the filler structure type and filler characteristics to polymer composites.
