摘要

采用激光闪蒸法测定了天然橡胶(NR)的热扩散系数和导热系数，并讨论了它们与硫化密度的关系。随着高阶结构的出现，NR的热扩散率和导热系数显著提高。此外，还发现硫化NR的热扩散系数或导热系数与其硫化密度呈正相关

Relationship between Vulcanizing Density and Thermal Diffusivity or Thermal Conductivity of Vulcanized Natural Rubber

Thermal diffusivity and thermal conductivity of natural rubber (NR) were measured by laser-flash method, and their vulcanizing density dependence was discussed. Thermal diffusivity and thermal conductivity of NR remarkably increased with appearance of higher-order structure by vulcanization. Furthermore, the positive correlation between thermal diffusivity or thermal conductivity of vulcanized NR and its vulcanizing density was found
