摘要: 本文以微胶囊红磷为主要阻燃剂,纳米SiO2 为增韧剂,采用共混熔融法制备阻燃型聚酯纤维样条,并研究阻燃剂及增韧剂用量对聚酯的阻燃性能和力学性能的影响。结果表明,微胶囊红磷能明显增强聚酯纤维的阻燃性能,纳米SiO2 的加入能改善聚酯纤维样条的力学性能; 微胶囊红磷含量为5% 时,聚酯纤维样条的极限氧指数(LOI) 值为33,拉伸强度为17.99MPa,弯曲强度为26.75MPa,冲击强度为1. 97kJ/m2,材料力学性能下降严重; 微胶囊红磷含量为3%、纳米SiO2 含量为2%时,聚酯纤维样条的LOI 值为29,拉伸强度为35.51N/mm2,弯曲强度为31. 54MPa,冲击强度为2.03kJ/m2,材料的综合性能最佳。

Abstract: In this paper,it uses microencapsulated red phosphorus which are the flame retardants and nano-SiO2 which are the flexibilizers to manufacture flame-retardant polyester fiber splines by melt blending method,and study the effect of the amount of flame retardants and tougheners to the flame-resistant and mechanical properties of polyester. The results showed that microencapsulated Red Phosphorus can significantly enhance the flame retardant properties of polyester fibers splines,and nano-SiO2 can improve the mechanical properties of the polyester fiber splines; When the content of microencapsulated red phosphorus was 5%,the polyester fiber splines exhibited a LOI value of 33,tensile strength of 17.99MPa,flexural strength of 26.75MPa,and impact strength of 1.97kJ/m2,and the mechanical properties of the materials declined seriously. When the content of microencapsulated red phosphorus was 3% and the content of nano-SiO2 was 2%,the polyester splines exhibited a LOI value of 29,tensile strength of 35.51MPa,flexural strength of 31.54MPa,and impact strength of 2.03kJ/m2.
