蒙脱土与阻燃剂的协效作用

STUDIES ON SYNERGISTIC EFFECT BETWEEN MMT AND FIRE RETARDANT

合成了有机改性蒙脱土(MMT),将PA6和PA66分别与改性MMT、阻燃剂共混制成纳米塑料,表征了其结构和性能,发现MMT/PA纳米塑料有抗熔滴等阻燃特点。发现改性MMT与阻燃剂之间有力学和阻燃协效作用,能同时提高塑料的力学和阻燃性能,这种协效作用有普遍性,本研究对其他纳米塑料体系的研究也有参考价值。

The organicallymodified MMT was hybridized with nylon 6, nylon 66 and fire retardants respectively. Their structures were characterized, mechanical testing was performed and the fire retardancy of this kind of polymer layered silicate nanoplastics was observered. Although the LOI of MMT/PA is not very high, but it can solve the problem of drippingmelt effectively. It shows that MMT is a kind of drippingmeltsuppressant. There is a kind of synergistic effect of mechanics and fire retardancy between MMT and other fire retardants, which improve the nylon′s properties in many aspects. This kind of synergistic effect is universal. These results will benefit the research of other nanoplastics.
