Abstract

Addressing the challenge of resource utilization of gold tailings. A high performance flame-retardant fillers (K-GTF) were prepared from gold tailings (GTF) by coupling and condensation for application to intumescent flame-retardant polypropylene (PP). K-GTF enhances the flame-retardant, thermal stability, smoke suppression and mechanical properties of flame-retardant PP through synergistic approach. The results show that K-GTF demonstrates good flame-retardant synergism, with PP composites containing 3% additive (PP/G3) exhibiting substantial flame-retardant and smoke suppression characteristics. Notably, PP/G3 boasts a limiting oxygen index (LOI) of 36.1%, which is substantially higher than the 33.6% LOI of the flame-retardant PP without added K-GTF (PP/G0). Furthermore, the peak heat release rate (PHRR), peak smoke production rate (PSPR), total heat release rate (THR), and total smoke production (TSP) of PP/G3 were decreased by 32.5%, 26.9%, 31.6%, and 21.5%, respectively, as compared to PP/G0. According to the synergistic mechanism analysis, K-GTF exerts a multi-component coupling synergistic effect, which promotes the production of phosphorus-rich cross-linking structures in flame-retardant PP materials during the combustion, thereby promotes the formation of stable, dense and intumescent char to further enhances the flame-retardant performance of the PP materials. In terms of mechanical effects, the introduction of K-GTF alleviates the issue of a substantial decline in mechanical properties typically caused by flame retardants in PP materials. This indicates that K-GTF improves the compatibility between the flame retardants and the PP matrix, thereby enhancing the mechanical properties of the flame-retardant PP materials.

资源金尾矿对膨胀型阻燃聚丙烯的多组分耦合协同效应

应对金尾矿资源化利用的挑战。以金尾矿（GTF）为原料，通过偶联缩聚法制备了一种高性能阻燃填料（K-GTF），并将其应用于膨胀阻燃聚丙烯（PP）中。K-GTF通过协同作用增强阻燃PP的阻燃性、热稳定性、抑烟性和力学性能。结果表明，K-GTF具有良好的阻燃增效作用，与添加3%添加剂（PP/G3）的PP复合材料具有较好的阻燃和抑烟性能。值得注意的是，PP/G3的极限氧指数（LOI）为36.1%，大大高于未添加K-GTF的阻燃PP （PP/G0）的33.6%。与PP/G0相比，PP/G3的峰值放热率（PHRR）、峰值产烟率（PSPR）、总放热率（THR）和总产烟率（TSP）分别降低了32.5%、26.9%、31.6%和21.5%。根据协同机理分析，K-GTF发挥多组分耦合协同效应，促进阻燃PP材料在燃烧过程中产生富磷交联结构，从而促进稳定、致密、膨胀的炭的形成，进一步提高PP材料的阻燃性能。在力学效果方面，K-GTF的引入缓解了PP材料中通常由阻燃剂引起的力学性能大幅下降的问题。这说明K-GTF改善了阻燃剂与PP基体的相容性，从而提高了阻燃PP材料的力学性能。成功合成阻燃增效剂（K-GTF）。K-GTF具有良好的协同阻燃效果。K-GTF显著提高了阻燃PP的成焦性和热稳定性，具有多组分耦合协同效应。K-GTF增强了PP基体与阻燃剂的相容性。
