摘要
采用焙烧还原法,辅助微波晶化手段快速合成MgAl-C6H5SO3-LDHs,并将其应用于乙烯-醋酸乙烯共聚物（EVA）中制备MgAl-C6H5SO3-LDHs/EVA复合材料。研究了MgAl-C6H5SO3-LDHs的不同添加量对复合材料阻燃性能的影响,并对其力学性能进行测试。结果表明：当MgAl-C6H5SO3-LDHs的添加量为70%,复合材料显示出较好的阻燃效果,其氧指数为32%,提高了68.4%。采用热失重法证实了随着MgAl-C6H5SO3-LDHs添加量的增加,促进复合材料在高温分解,其在420~500℃区间的失重变化也越来越不明显;当MgAl-C6H5SO3-LDHs添加量为60%和70%时失,重曲线分别有向低温区和高温区延伸的趋势。
MgAl-C6H5SO3-LDHs was prepared by the roasting reduction method assisted with microwave- crystallization, and then the MgAl-C6H5SO3-LDHs/ethylene vinyl acetate copolymer （EVA） composites was prepared by blending the synthesized samples and EVA. The flame retardancy and mechanical properties of the MgAl-C6H5SO3-LDHs/EVA composites with different content of MgAl-C6H5SO3-LDHs were studied. The results showed that when the MgAl-C6H5SO3-LDHs content was 70%, the flame retardancy of composites was better, then the oxygen index was 32%, increased by 68.4%. The thermal gravimetric method revealed that the decomposition of composites in high temperature was promoted with the increase of MgAl-C6H5SO3-LDHs, moreover, the weight loss changes could be neglect in range of 420~500 ℃ . The weight loss curve showed that the weight loss curves of composites exhibited the tendency to extend to high temperature zone and low temperature zone respectively when the addition of MgAl-C6H5SO3- LDHs was 60% and 70%.
