| 摘 要： | 以三元乙丙胶（EPDM）与氯化聚乙烯（CM）并用为主体材料，根据耐高热输送带覆盖胶性能要求，采用机械共混、化学交联工艺制得EPDM／CM耐高热胶带覆盖胶，初步探讨了EPDM／CM共混比例、硫化体系、补强填充剂对覆盖胶性能的影响。实验结果表明，采用EPDM-K512／EPDM-4050／CM-352L的共混比为35／65／30时，既能改善胶料工艺性能，又提高了其拉伸强度、硬度；采用过氧化二异丙苯（DCP）／硫磺（S）／三烯丙基异氰脲酸酯（TAIC）的比例为5．5／0．3／2时，有良好的耐热老化性能和拉伸强度；此外采用中超炭黑（ISAF）／通用炭黑／白炭黑的配比为45／10／5时补强体系的性能最好。

| Abstract: | According to the properties requested of high-heat-resistant belt, the cover coat blent with EPDM and CM was made by technology of mechanical and chemical crosslinking. The effect of the ratio of EPDM/CM,curing agents and reinforcements on the properties of EPDM/CM blends was discussed. The results showed that the blends had good processing property, high tensile strength and high hardness as the ratio of EPDM - K512/EPDM - 4045/CM - 352L was 35/65/30. The blends had good heat resistance and tensile as the ratio of DCP/S/TAIC was 5.5/0.3/2. Besides, when the ratio of ISAF/general black/precipitated silica was 45/10/5 ,the general properties was best. |
