中文摘要：

以过氧化二异丙苯（DCP）和硫黄（S）为硫化剂,研究了甲基丙烯酸锌（ZDMA）和炭黑（CB）在多官能化改性天然橡胶（MFNR）中的填充行为。利用扫描电镜分析了MFNR在混炼和硫化过程中填料粒子的尺寸和形貌,并研究了硫化胶的静态和动态性能。结果表明,硫化后填料粒子的尺寸明显变小,分散更加均匀。ZDMA加快了硫化反应速率,增大了体系的交联密度,硫化胶的力学性能提高,压缩温升和永久变形明显减小,玻璃化转变温度变化不大。

英文摘要：

This article researched ZDMA/CB was applied in MFNR with DCP and S as vulcanizing agent.The filler particles of the size and morphology and the static and dynamic properties of the vulcanizates of the MFNR were studied in the process of mixing and curing by using scanning electron microscopy（SEM）.The experimental results showed that the filler particle size decreased significantly after vulcanization.ZDMA accelerated the curing reaction rate and increased the crosslinking density of the system.The mechanical properties of vulcanized rubber increased,The compression and permanent deformation temperature decreased obviously.
