| 摘 要： | 选用马来酸酐接枝聚丙烯（MP）作为丙烯酸酯橡胶（ACM）/聚丙烯（PP）热塑性硫化橡胶（TPV）的相容剂，研究了三巯基均三嗪（TCY）和过氧化二异丙苯（DCP）不同硫化体系和硫化剂含量，以及邻苯二甲酸二辛酯（DOP）增塑剂，对TPV微观结构和物理性能的影响。结果表明，DCP比TCY硫化体系的作用效果好，当采用2份（质量份,下同）DCP时，制备的TPV微观相态结构和拉伸、撕裂性能最佳，压缩永久变形和耐油性良好;增塑剂DOP的加入降低了TPV的肖A硬度，增加了TPV的弹性;当DOP含量为30份时，TPV具有较好的相态结构，在有效降低其硬度的同时，力学性能、耐油性和弹性保持相对较好。

| Abstract: | Maleic?modified polypropylene was used as a compatibilizer to prepared ACM/PP thermoplastic vulcanizates (TPV), and the effects of trithiocyanuric acid (TCY) and dicumyl peroxide (DCP) as vulcanizaters and dioctyl phthalate (DOP) as a plasticizer on the microstructure and physical properties of TPV were investigated. The results indicated that DCP exhibited a better vulcanizing effect than TCY, and the obtained TPV presented a desired microstructure and phase structure. The TPV achieved the optimum tensile and tear properties when 2 phr of DOC was incorporated, and it also showed the excellent compression set and oil resistance. The introduction of DCP decreased the hardness of TPV but enhanced its elasticity. A fine microstructure and good physical properties and elasticity were achieved for the TPV when 30 phr of DOP was added, and meanwhile the hardness was reduced effectively. |
