摘要/Abstract

摘要： 采用牌号为FL7641L、TF400、PPH-T03 的3 种聚丙烯（PP）为增韧剂，以牌号为8540、9071、DF810 的3种聚烯烃弹性体（POE）以及聚烯烃弹性体接枝马来酸酐（POE-g-MAH）为增容剂，利用共混改性的方法对尼龙66 进行增韧改性研究。实验结果表明：POE-g-MAH 对尼龙66 的增韧效果明显，牌号为TF400 的聚丙烯对尼龙66在一定范围内有增韧效果，POE的增韧效果不明显；并且增韧剂的加入均使共混材料的熔体质量流动速率（MFR）有所下降；在PP/POE-g-MAH/尼龙66 三元共混材料中，当PP 含量（质量分数）为8%、POE-g-MAH含量为15%、尼龙66含量为77%时，共混材料的简支梁缺口冲击强度为11. 09 kJ/m2，是纯尼龙66的397. 5%，可以明显地提高尼龙66的冲击性能。

Abstract: This experiment adopted three types of polypropylene (PP) with the brand of FL7641L, TF400, PPH-T03 as toughening agent, and three kinds of polyolefin elastomer (POE) with the brand of 8540, 9071, DF810 and polyolefin elastomer grafted maleic anhydride (POE-g-MAH) as compatibilizer, using the method of blending modification to study on toughening modification of nylon 66. The result showed that: the POE-g-MAH was apparent on toughening effect of nylon 66. The PP with brands of TF400 had toughening effect within a certain range, and the toughening effect of POE was not obvious; the toughening agents all made the mass flow rate (MFR) of blending material decrease; In PP/POE-g-MAH/nylon 66 blending material, when the content of PP was 8% (mass fraction, the same below), the content of POE-g-MAH was 15%, the content of nylon 66 was 77%, the impact strength of blending materials reached 11. 09 kJ/m2, it was 397. 5% as much as pure nylon 66. It can significantly improve the impact properties of nylon 66.
