| 摘 要： | 在适宜的条件下将纳米CaCO3用硬脂酸通过超高速混合进行表面处理。采用熔融共混工艺制备了PA6/纳米CaCO3复合材料。结果表明，纳米CaCO3含量为1份左右时复合材料的拉伸强度达到最大值，比PA6高约11%，纳米CaCO3含量10份左右时复合材料缺口冲击强度达到最大值，比PA6高约40%；复合材料的拉伸弹性模量随纳米CaCO3含量增加而提高，在纳米CaCO3含量为10份时较PA6提高约20%，20份时提高约30%。 |

PREPARATION AND PROPERTIES OF PA6/CaCO3 NANOCOMPOSITES |
|
| Abstract: | PA6/CaCO3 nanocomposites were prepared by surface pretreatment of nano-CaCO3 with stearic acid using highspeed blender. The results showed that adding about 1 part of nano-CaCO3, the tensile strength of nanocomposites reached to maximum, which was about 11% higher than that of PA6, adding about 10 parts of nano-CaCO3, the Izod notched impact strength of composites reached to maximum, which was about 40% higher than that of PA6. The tensile modulus of nanocomposites increased with the adding of nano-CaCO3, which was about 20% higher than that of PA6 when adding 10 parts of nano-CaCO3 and about 30% higher than that of PA6 when adding 20 parts of nano-CaCO3. |
