摘要
Abstract
Nylon 66 possesses good mechanical and thermal properties but has relatively insufficient toughness.In this paper,nylon 6 elastomer was selected to modify nyl66 via co-extrusion blending to study the changes in its mechanical and thermal properties,providing a pathway for the toughening modification of nylon 66.Using PA66 as the base material,different amounts of nylon 6 elastomer 3010 and 6510 were added,along with antioxidants and lubricants.The mixture was then mixed and granulated using a twin-screw extruder.The tensile,bending,impact,and ther-mal properties of nylon 66 modified by different amounts of nylon 6 elastomer were studied.The results showed that when the amount of nylon 6 elastomer 3010 was 15%,the retention rate of the mechanical and thermal properties of nylon 66 was over 70%,and its impact strength in-creased by 3 to 5 times.By analyzing the DSC curve and melting peak area of nylon 66 with different contents of nylon elastomer toughening a-gent,it was concluded that the compatibility with the nylon 66 base material was good,and the addition of nylon elastomer reduced the crystallin-ity and crystallization temperature of the nylon 66 base material.关键词
