MCA/ZDP协同改性聚酰胺6阻燃性能与力学性能研究
Study on Flame Retardancy and Mechanical Properties of Polyamide 6 Synergistically Modified by MCA/ZDP
摘要
Abstract
Polyamide 6(PA6)possesses excellent mechanical properties,wear resistance,and chemical corrosion resistance,and is widely used in the textile,apparel,electronic,and electrical fields.However,the inherent flammability of PA6 hinders its further application in more fields.In the study,nitrogen-based flame retardant melamine cyanurate(MCA)and phosphorus-based flame retardant zinc diethylphosphinate(ZDP)were used to synergistically modify PA6,and flame-retardant PA6 was prepared via melt compounding.The properties of the flame-retardant PA6 were investigated.The results showed that with increasing flame retardant content,the melting point and thermal stability of flame-retardant PA6 exhibited a gradual decreasing trend,while the mechanical properties first increased and then decreased.When the mass fraction of MCA was 8%and that of ZDP was 4%,the melting point and initial decomposition temperature of PA6/MCA/4ZDP decreased to 218.3℃and 325.0℃,respectively.The tensile strength and elongation at break of PA6/MCA/4ZDP reached their minimum values of 46.8 MPa and 20.3%,respectively.When the mass fraction of MCA was 8%and that of ZDP was 2%,PA6/MCA/2ZDP exhibited the best flame retardancy,with a UL94 vertical burning rating of V-0 and a limiting oxygen index(LOI)of 30.1%.关键词
