材料组分对PP/PE-LD水发泡注塑件延展性能的影响
Effect of Composition on Ductility of PP/PE-LD Water-foamed Injection-molded Parts
摘要
Abstract
Compounding or blending is normally considered a good method to produce new polymeric materials for special uses.However,the ductility of polypropylene (PP)/low-density polyethylene (PE-LD)blends is relatively poor.PP/PE-LD microporous samples were prepared via conventional injection molding using water as a blowing agent, and their mechanical properties and microstructure were investigated.The results suggest that the formation of microporous structure enhanced the ductility of PP/PE-LD blends,and their mechanical properties and microstructure were influenced by the compositions of PP/PE-LD blends.A fine microporous structure was observed in the PP-content range of 90 %～50 %,which was attributed to the poor compatibility between the PP and PE-LD phases.This makes the ductility improved much easilier.关键词
