摘要:
采用反应挤出加工工艺,以甲基丙烯酸环氧丙酯接枝改性乙烯-辛烯共聚物(mPOE)为增容剂,对回收聚对苯二甲酸乙二醇酯(R-PET)与线性密度聚乙烯(LLDPE)共混物进行增容增韧改性,考察了增容剂mPOE用量对R-PET/LLDPE/mPOE共混物的相结构、力学性能以及熔融、结晶行为的影响.扫描电镜(SEM)结果表明:R-PET/LLDPE/mPOE共混物中分散相的粒径和粒间距随着mPOE含量的增加而迅速减小; 而当增容剂的添加质量分数大于5%后,分散相粒径大小与粒间距的变化趋于减小.力学性能测试表明:R-PET/LLDPE/mPOE共混物的断裂伸长率和缺口冲击强度随着mPOE含量的增大先迅速增大,后变化趋缓.DSC结果表明:R-PET/LLDPE/mPOE共混物随着mPOE含量的增加,分散相粒子对R-PET结晶的成核效果降低.
Abstract:
In the present study,high-toughen and low-cost recycled poly(ethylene terephthalate)(R-PET)engineering plastics is prepared by R-PET blended with linear low density polyethylene(LLDPE),compabilitied with poly(ethylene-octene)grafted glycidyl methacrylate(mPOE)via reactive extrusion.The effect of mPOE content on morphology and properties of R-PET/LLDPE blends is investigated.The results show that dispersed phase particles size and interparticle distance reduce with increasing mPOE content,but keep constant above the critical compatibilizer concentration about 5wt%.The mechanical properties test shows that the breaking elongation and notched impact strength of R-PET/LLDPE/mPOE blends increase rapidly with the increase of mPOE content,and then decrease slowly.DSC results show that with the increase of mPOE content in the blends,the nucleation effect of R-PET decrease.
