The use of polymer materials is inextricably linked to our manufacturing life. However, most of them are easily combusted in the air and the combustion process generates a large amount of toxic fumes and dangerous smoke. This can result in injuries and property damage, as well as limiting their use. It is essential to enhance the flame-retardant properties and smoke suppression performance by using multiple flame retardants. Metal-based flame retardants have a unique chemical composition. They are environmentally friendly flame retardants, which can impart good smoke suppression, flame retardancy to polymers and further reduce the production of toxic gases. The differences in the compounds formed between the transition metals and the main group metals make them act differently as flame retardants for polymers. As a result, this study presents the research progress and flame-retardant mechanism of flame-retardant polymers for flame retardants from different groups of metals in the periodic table of elements in a systematic manner. In view of the differences between the main group metals and transition metals, the mechanism of their application in flame retardant polymer materials is carefully detailed, as are their distinct advantages and disadvantages. And ultimately, prospects for the development of transition metals and main group metals are outlined. It is hoped that this paper will provide valuable references and insights for scholars in the field.
聚合物材料的使用与我们的制造生活紧密相连。然而，它们中的大多数在空气中易于燃烧，并且燃烧过程会产生大量有毒烟雾和危险烟尘。这可能导致人员伤亡和财产损失，也限制了它们的使用。通过使用多种阻燃剂来提高阻燃性能和抑烟性能至关重要。金属基阻燃剂具有独特的化学成分。它们是环境友好型阻燃剂，能够赋予聚合物良好的抑烟性和阻燃性，并进一步减少有毒气体的产生。过渡金属与主族金属形成的化合物差异使得它们作为聚合物阻燃剂的作用方式不同。因此，本研究系统地介绍了元素周期表中不同金属族的阻燃剂在阻燃聚合物方面的研究进展和阻燃机理。鉴于主族金属和过渡金属之间的差异，详细阐述了它们在阻燃聚合物材料中的应用机理以及各自明显的优缺点。最终，概述了过渡金属和主族金属的发展前景。希望本文能为该领域的学者提供有价值的参考和见解。
