• 摘要： 聚苯乙烯（PS）是一種多功能材料，具有優異的機械性能、電性能、耐氣候老化性，還具有優良的加工成型性能。但是聚苯乙烯是一種易燃的材料，當其暴露于空氣中時，其表面會形成一層極薄的可燃物質，在一定程度上降低了聚苯乙烯的阻燃性能。因此，必須對聚苯乙烯進行阻燃改性，以提高其阻燃性能。本文從阻燃性能的角度出發，綜述了阻燃聚苯乙烯材料的最新研究進展，介紹了通過聚合階段阻燃法、后處理涂層法阻燃、浸漬階段添加法阻燃和包覆法阻燃的研究進展，對其阻燃性能進行了分析和總結，旨在為制備具有較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.
