| 摘 要： | 通过熔融共混的方法制备PA66/POE-g-MAH/纳米SiO_2三元共混体系,研究纳米SiO_2、POE-g-MAH对PA66力学性能的影响.研究结果表明:POE-g-MAH与纳米SiO_2对PA66有协同增韧效应,当PA66/POE-g-MAH/纳米SiO_2配比为100/30/0.1时,复合体系的缺口冲击强度达到最大,为纯PA66的10.9倍,为PA66/POE-g-MAH(100/30)二元体系的1.8倍;低温缺口冲击强度也达到最大,为纯PA66的6.3倍.用扫描电镜观察分析冲击断口形态.

| Abstract: | PA66/POE-g-MAH/nano-SiO_2 compasite was prepared by melt blending. The effects of nano-SiO_2 andPOE-g-MAH on the mechanical property of PA66/POE-g-MAH/nan-SiO_2 composite were studied. The results showed thatnano-SiO_2 and POE-g-MAH had a synergetic toughening effect on PA66. The impact strength of PA66/POE-g-MAH/nano-SiO_2reached the maximum, which was about 10.9 times as high as that of PA66 and 1. 8 times as high as that ofPA66/POE-g-MAH (100/30),when the mass ratio of PA66/POE-g-MAH/nano-SiO_2 composite was 100/30/0.1.The impactstrength of the composite at low temperature was also greatly improved, the maximum was about 6. 3 times as high as that ofPA66. The impact fracture of composite was studied by SEM. |
