| 摘 要： | 采用双辊混炼和挤出制样的方法制备了纳米CaCO3/EPR/PP复合材料。通过PCM、TEM及力学性能测试研究了复合材料的力学性能及EPR和CaCO3粒子的分散状况。在纳米CaCO3/EPR/PP复合体系中,纳米CaCO3粒子的加入,不但使冲击强度显著提高,而且使弯曲弹性模量显著提高。纳米CaCO3粒子的增韧机理在于纳米CaCO3粒子的加入使弹性体EPR的分散更加均匀,EPR颗粒的粒径变小,进而与纳米CaCO3粒子产生协同增韧的作用。

| Abstract: | Nano-CaCO_3/EPR /PP composite was prepared by the two-roll mill and extruder. The mechanical properties of the composite and the dispersion of EPR and Nano-CaCO_3 were investigated by means of PCM,TEM and mechanical test. The results show that not only the impact property but also the bending modulus of the system have been evidently increased by adding nano-CaCO_3. The toughening mechanism of the nano-CaCO_3 is due to the fact that the addition of nano-CaCO_3 particles makes the EPR well-distributed and the EPR particle size small, leading to the cooperative toughening by the reaction between the smaller EPR particles and the nano-CaCO_3 particles. |
