摘要
对纳米Mg(OH)2表面处理,用之阻燃改性尼龙6,测定了Mg(OH)2/PA6体系的燃烧性能和力学性能。结果表明,当Mg(OH)2的用量为40%以上时,Mg(OH)2/PA6的UL-94阻燃性可达V-0,氧指数(LOI)高于30%;当Mg(OH)2的用量为30%时,Mg(OH)2/PA6体系的拉伸强度、弯曲强度、缺口冲击强度分别为82.7MPa、128.8MPa、6.0KJ/m2。
PA6 was flame retarded with modified nano Mg(OH) 2.The limited oxygen index(LOI ),UL 94 flame retar-dancy and mechanical properties of the flame retarded PA6 were determined.The results show that the LOI and UL 94 of the composite with 40wt%of Mg(OH) 2 is 31%and V-0 respectively.Tensile strength,bending strength and notched impact strength of Mg(OH) 2/ PA6 with 30wt%of Mg(OH) 2 is 82.7 MPa,128.8 MPa,6.0 KJ/m2 respectively.
