首先制备了噁唑啉官能化的废旧苯乙烯-丁二烯-丙烯腈共聚物(R-ABSm),并制备了废旧电器外壳高抗冲聚苯乙烯(R-HIPS)/R-ABSm/SEBS-g-MAH 共混物。通过对力学性能、傅里叶变换红外光谱(FT-IR)、扫面电镜(SEM)和动态力学性能(DMA)的测试,得出了当用噁唑啉官能化的 R-ABS 代替 R-ABS 时,R-HIPS/R-ABSm/SEBS-g-MAH 共混物比R-HIPS/R-ABS/SEBS-g-MAH 共混物的缺口冲击强度提高了43％；从扫描电镜可以看出 R-HIPS/R-ABSm/SEBS-g-MAH 共混物中 R-HIPS 和 R-ABSm 基体间相界面模糊。证明在 R-HIPS/R-ABSm/SEBS-g-MAH 共混物噁唑啉环与马来酸酐发生了化学反应,原位生成了相容剂,使得共混物基体相相界面结合力增强,相容性提高。
In the paper,firstly,the oxazoline functionalized recycled acrylonitrile-butadiene-styrene copolymer (R-ABSm)and R-HIPS/R-ABSm/SEBS-g-MAH blend were prepared.The mechanical properties,Fourier transform infrared spectroscopy (FT-IR),dynamic mechanical analysis were measured in this study.The re-sults indicate that the impact strength of R-HIPS/R-ABSm/SEBS-g-MAH blend improved by 43% when using R-ABSm instead of R-ABS.In the SEM analysis,the phase interface between R-HIPS and R-ABSm of the R-HIPS/R-ABSm/SEBS-g-MAH blend was fuzzy matrix.It is proved that the compatilizer was obtained in situ from the chemical reaction happened in the oxazoline ring and maleic anhydride of the R-HIPS/R-ABSm/SEBS-g-MAH blend,which enhanced the interface bonding and improved the compatibility of the R-HIPS/R-ABSm/SEBS-g-MAH blend.
