• 摘要： 聚苯乙烯（PS）是一种多功能材料，具有优异的机械性能、电性能、耐气候老化性，还具有优良的加工成型性能。但是聚苯乙烯是一种易燃的材料，当其暴露于空气中时，其表面会形成一层极薄的可燃物质，在一定程度上降低了聚苯乙烯的阻燃性能。因此，必须对聚苯乙烯进行阻燃改性，以提高其阻燃性能。本文从阻燃性能的角度出发，综述了阻燃聚苯乙烯材料的最新研究进展，介绍了通过聚合阶段阻燃法、后处理涂层法阻燃、浸渍阶段添加法阻燃和包覆法阻燃的研究进展，对其阻燃性能进行了分析和总结，旨在为制备具有较好阻燃性能的阻燃聚苯乙烯材料提供新思路。
• Polystyrene (PS) is a multi-functional material, with excellent mechanical properties, electrical properties, weathering resistance, but also has excellent processing and forming properties. However, polystyrene is a flammable material, and when it is exposed to air, its surface will form an extremely thin layer of flammable substances, which reduces the flame retardant performance of polystyrene to a certain extent. Therefore, flame retardant modification of polystyrene must be carried out to improve its flame retardant performance. The commonly used flame retardants are mainly nitrogen and phosphorus flame retardants and silicon flame retardants. In this paper, several common flame retardant methods of polystyrene are briefly introduced, their flame retardant mechanism is analyzed and compared, and the flame retardant modification methods and processes of different types of polystyrene in the process of processing and molding are discussed.
