摘　　要：探索了高铁M-3000A无转子硫化仪(MDR)在动态力学方面的应用,得知可用MDR测量定频、定温、定时下的S′(弹性值)、S″(黏性值)、δ(相角)、G′(储能模量)、G″(损耗模量)、Δδ来表征TPV的动态力学性能。结果表明,随动态硫化时间的进行,ACM/TPEE(H55DMG)TPV的S″、δ增大;随S用量的增加,MPU/TPEE(H28DMG)TPV的S′、S″、G′、G″增加,δ和减Δδ减小。The application of high-speed rail M-3000A moving die rheometer (MDR) in dynamic mechanics was explored in this paper. It is known that MDR can be used to measure S'(elastic value), S''(viscosity value),δ(phase angle), G'(storage modulus), G''(loss modulus) and Δδ under fixed frequency, constant temperature and timing, then to characterize the dynamic mechanical properties of TPV. The results show that the S'' and δ of the ACM/TPEE (H55DMG) TPV increased with the progress of the dynamic vulcanization time;As the amount of S increases, S', S'', G', G'' of MPU/TPEE (H28DMG) TPV increased, while δ and Δδ decreased.
