用XRD法分析天然胶/杜仲胶共混硫化胶的结晶性,研究其结晶性对天然胶/杜仲胶共混硫化胶的物理性能和热致形变性能的影响.实验结果表明:随着杜仲胶用量的增加,硫化胶在XRD图谱中的衍射峰强度增大,硫化胶的结晶性增大,硫化胶交联密度有明显减小.定伸应力和拉伸强度随杜仲胶用量的增加而增大,而拉断伸长率减小,热致回复温度降低,试样的最终形变率减小.
XRD analysis of the natural rubber / Eucommia bum blend vulcanizates crystallinity, crystallinity on natural rubber / Eucommia bum blend vulcanizates physical properties and thermal deformation properties of experimental results show that: with the Eucommia gum With the increase of the dosage, the intensity of the diffraction peak of the vulcanizate in the XRD spectrum increases, the crystallinity of the vulcanizate increases, and the crosslinking density of the vulcanizate decreases obviously. The tensile strength and tensile strength of the vulcanizate increase with the increase of the dosage of Eucommia Large, while the tensile elongation decreased, the heat-induced recovery temperature decreases, the final sample deformation rate decreases.
