| 摘 要： | 以过氧化二异丙苯(DCP)为引发剂,在转矩流变仪中自制马来酸酐(MAH)接枝改性天然橡胶(NR)(MNR),将其作为超细碳酸钙/天然橡胶复合材料(CaCO3/NR)的改性剂,研究了MNR对于CaCO3/NR复合材料的力学性能、应力软化效应以及应力弛豫行为的影响。研究结果表明,MNR改性后CaCO3/NR复合材料较之未改性复合材料拉伸强度、撕裂强度和硬度等力学性能均有所提高,应力软化效应加剧,应力弛豫程度和速度降低,力学行为研究结果证实MNR可有效改善CaCO与NR基体间的界面粘合。

| Abstract: | Grafting of Maleic anhydride (MAH) onto natural rubber (NR) was carried out in a Torque Rheometer with Dicumyl peroxide (DCP) as initiator. Then the self-prepared maleated natural rubber (MNR) was used as modifier of the suerfine calcium carbonate filled natural rubber composites (CaCO_3/NR). Effects of MNR on the mechanical properties, stress softening and stress relaxation behaviors of CaCO_3/NR composites were studied. Results show that the tensile strength, tear strength and Shore A hardness of CaCO_3/N... |
