红磷与交联的结构对聚酰胺阻燃性能的影响

The effect of red phosphorus and cross-links on flame resistance of polyamide

在没有经过辐照过的样品中添加红磷,即使掺杂量达到12.5%,都不能很好的提高PA-6的阻燃性。当PA-6经过60Co-γ-rays照射产生了交联结构后,其阻燃性能会得到很大的提高,并且在这种混合体系中添加TAC来降低照射的能量。

Red phosphorus contained in non-irradiated polyamide-6 at concentrations up to 12.5 does not significantly improve the fire resistance of the polymer. Irradiation of polyamide-6, loaded with red phosphorus, with ^60Co-γ-rays generates intermolecular cross-links resulting in an improved fire resistance. From a practical point of view. This inconvenience is overcome by applying trialyl cyanurate （TAC） as a cross-linking promoter.
