Abstract

Epoxy resins (EP) have been commonly used, but their poor flame retardant properties have prevented their widespread use. In order to improve the flame retardant properties of EP, an organic-inorganic composite flame retardant (HKDC) containing multi-element P/N/Si was successfully synthesized in this work using a typical aldehyde amine condensation reaction. This flame retardant utilizes the synergistic effect of multiple elements to simultaneously perform the flame retardant function of each element, and it can achieve excellent flame retardant effect by using low addition amount in EP. At the same time, this flame retardant can not only reduce the migration of molecules through the structure of inorganic substances, but also the C = C reaction in EP can form large molecules and increase the compactness with the EP matrix. The flame retardants were then quantified by measuring their flame retardant properties, combustion behavior and thermal stability. When the flame retardant HKDC is added, the flame retardant performance of EP is improved and the vertical combustion test achieves a V-0 rating. Most importantly, the addition of flame retardant HKDC effectively suppressed the toxic gas and smoke emissions of EP, with TSP values much lower than those of pure EP, and CO and CO2 emissions were suppressed.

多元素有机-无机阻燃剂，用于增强环氧树脂的阻燃性，降低烟雾和毒性

环氧树脂（EP）已被广泛使用，但其较差的阻燃性能阻碍了其广泛使用。为了改善EP的阻燃性能，本工作采用典型的醛胺缩合反应成功合成了一种含有多元素P/N/Si的有机-无机复合阻燃剂（HKDC）。该阻燃剂利用多种元素的协同作用，同时发挥各元素的阻燃作用，在EP中使用低添加量，可以获得优异的阻燃效果。同时，这种阻燃剂不仅可以减少分子通过无机物质结构的迁移，而且EP中的C=C反应可以形成大分子，增加与EP基体的紧密性。然后通过测量阻燃剂的阻燃性能、燃烧行为和热稳定性来量化阻燃剂。当添加阻燃剂HKDC时，EP的阻燃性能得到改善，垂直燃烧试验达到V-0等级。最重要的是，阻燃剂HKDC的加入有效地抑制了EP的有毒气体和烟雾排放，TSP值远低于纯EP，CO和CO2的排放也得到了抑制。

期刊介绍： Health Services Management Research (HSMR) is an authoritative international peer-reviewed journal which publishes theoretically and empirically rigorous research on questions of enduring interest to health-care organizations and systems throughout the world. Examining the real issues confronting health services management, it provides an independent view and cutting edge evidence-based research to guide policy-making and management decision-making. HSMR aims to be a forum serving an international community of academics and researchers on the one hand and healthcare managers, executives, policymakers and clinicians and all health professionals on the other. HSMR wants to make a substantial contribution to both research and managerial practice, with particular emphasis placed on publishing studies which offer actionable findings and on promoting knowledge mobilisation toward theoretical advances. All papers are expected to be of interest and relevance to an international audience. HSMR aims at enhance communication between academics and practitioners concerned with developing, implementing, and analysing health management issues, reforms and innovations primarily in European health systems and in all countries with developed health systems. Papers can report research undertaken in a single country, but they need to locate and explain their findings in an international context, and in international literature.
