Abstract
本发明涉及一种无卤阻燃力学协同增强复合助剂及其制备方法和应用，该复合助剂包括以下质量组分：γ‑氨丙基三乙氧基硅烷接枝聚磷酸铵6.5‑7.5份、马来酸酐接枝ABS0.5‑1.0份、环氧基封端DOPO衍生物2.0‑3.0份、有机蒙脱土1.2‑2.2份、聚四氟乙烯微粉0.2‑0.4份及复合抗氧剂0.2‑0.3份。该复合助剂用于对PC与ABS组成的再生共混合金进行改性。本发明通过凝聚相催化炭化、气相自由基捕获、纳米物理阻隔及抗滴落增强的四级阻燃机制，实现了低添加量下的高阻燃效率；通过界面化学键合增强、纳米片层增韧和分子链断裂修复的三重作用，改善了传统阻燃体系“阻燃提升必牺牲力学性能”的问题。
