Abstract

In this study, hydroxyl-terminated carborane polyarylates were directly reacted with isocyanates by direct main chain introduction method. Three carborane polyurethane resins were prepared by using polyarylates and isocyanates. The best curing process conditions were determined through curing kinetics research and experiments. TGA, DSC, XRD and variable temperature infrared spectroscopy were used to investigate the thermal properties. The combustion performance was studied by heat release rate (HRR), total heat release (THR) and limiting oxygen index (LOI). The surface morphology after heat treatment of carborane polyurethane resin and traditional polyurethane was observed by SEM method and focused on the stability of carborane polyurethane resin.

高性能高残炭阻燃碳硼烷聚氨酯的制备与表征

本研究采用直接主链引入法，将端羟基碳硼烷聚芳酯与异氰酸酯直接反应。以聚芳酸酯和异氰酸酯为原料制备了三种碳硼烷聚氨酯树脂。通过固化动力学研究和实验，确定了最佳固化工艺条件。采用TGA、DSC、XRD和变温红外光谱对其热性能进行了表征。通过放热率(HRR)、总放热率(THR)和极限氧指数(LOI)对燃烧性能进行了研究。采用扫描电镜(SEM)对碳硼烷聚氨酯树脂和传统聚氨酯热处理后的表面形貌进行了观察，重点研究了碳硼烷聚氨酯树脂的稳定性。

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.
