摘要

随着环氧树脂（EP）的广泛应用，寻找一种合适的方法来提高EP的阻燃性以满足其在高阻燃领域的应用要求一直是一个热门的研究课题。本文采用有机-无机杂化策略合成了一种新型含硼硅沸石杂化材料（Zeolite@BSi），并将其应用于阻燃EP。7 wt% Zeolite@BSi的极限氧指数（LOI）为28.7 %，EP为V-0级。与EP相比，EP/Zeolite@BSi的峰值放热率（PHRR）、总放热率（THR）和总产烟率（TSP）分别显著降低34.05 %、25.42 %和33.14 %。Zeolite@BSi通过促进更连续的炭层的形成来保护EP基质，从而减少热量和烟雾的释放。重要的是，Zeolite@BSi的加入不仅提高了EP的阻燃性能，而且在一定程度上提高了EP的力学性能。本研究为开发具有优异阻燃性能和良好力学性能的EP复合材料提供了新的思路。

A novel boron and silicon hybrid zeolite flame retardants for reducing the fire hazard of epoxy resin

With the wide application of epoxy resin (EP), searching for a suitable method to improve the flame retardancy of EP to meet the requirements of its application in the field of high flame retardance has been a hot research topic. In this work, a novel boron and silicon containing zeolite hybrid material (Zeolite@BSi) was synthesised by organic-inorganic hybrid strategy and applied to flame retardant EP. The 7 wt% Zeolite@BSi conferred a limiting oxygen index (LOI) of 28.7 % and a V-0 rating on EP. Compared with EP, the peak heat release rate (PHRR), total heat release (THR) and the total smoke production (TSP) of EP/Zeolite@BSi were significantly reduced by 34.05 %, 25.42 % and 33.14 %, respectively. Zeolite@BSi protects the EP matrix by promoting the formation of more continuous char layers, thereby reducing heat and smoke release. Importantly, the addition of Zeolite@BSi not only improves the flame retardant performance of EP, but also enhances the mechanical properties of EP to some extent. This study provides a new strategy for developing EP composites with excellent flame retardance and good mechanical properties.
