| 摘 要： | 研究了橡塑比、过氧化物复合硫化体系及KH-570硅烷偶联剂对动态硫化EPDM/PP/SiO2共混物的力学性能的影响.结果表明,随着PP含量的增加.动态硫化EPDM/PP/SiO2共混物的力学性能和硬度增加,但压缩永久变形增加,断裂伸长率却减小.过氧化物复合硫化体系中,当DCP为1.5份时,动态硫化EPDM/PP/SiO2共混物的综合物理力学性能较好.加入KH-570改性的白炭黑,对EPDM/PP/SiO2共混物起到补强的作用;且提高共混物的交联密度,降低压缩永久变形.

| Abstract: | Effects of rubber-plastic ratio,peroxide composite curing system and KH-570 silane coupling agent on the mechanical properties of dynamic vulcanized EPDM/PP/SiO2 blends were studied.The results show that the mechanical properties and hardness of the dynamic vulcanized EPDM/PP/SiO2 blends increase gradually with the increase of the PP amount;that the compression set increases while the elongation at break reduces.When the DCP of peroxide composite curing system is 1.5phr,dynamically vulcanized blends EPDM/PP... |
