Starting from renewable Cardanol, a novel inherently fire-retardant UV curable bio-based prepolymer (AEHCPP) with phosphazene core and six Cardanol arms are prepared in this report. The chemical structure of all newly prepared intermediates compounds and AEHCPP are well-characterized using nuclear magnetic resonance (NMR) and Fourier transform infrared spectroscopy (FTIR). UV-curable mixture consisting of AEHCPP and different diluents were formulated and their photopolymerization dynamics were investigated on Photo-calorimetry (photo-DSC). The thermal properties of crosslinked coatings were estimated using thermal analysis technology. Differential Scanning Calorimetry (DSC) and Dynamic Mechanical Analysis (DMA) results show that glass transition temperatures of all cured films are above room temperature (>30 °C), the 5% weight loss temperature in nitrogen is higher than 266 °C. The fire-retardant properties are estimated by TGA and all calculated Limiting Oxygen Index (LOI) values are over 24, implying the excellent fire-resistance of cured films.

从可再生的腰果酚开始，本报告制备了一种新型的固有阻燃性紫外线可固化生物基预聚物（AEHCPP），其具有磷腈核和六个腰果酚臂。使用核磁共振（NMR）和傅立叶变换红外光谱（FTIR），可以很好地表征所有新制备的中间体化合物和AEHCPP的化学结构。配制了由AEHCPP和不同稀释剂组成的可紫外固化混合物，并通过光量热法（photo-DSC）研究了它们的光聚合动力学。使用热分析技术评估了交联涂层的热性能。差示扫描量热法（DSC）和动态力学分析（DMA）结果表明，所有固化膜的玻璃化转变温度均高于室温（> 30°C），氮气中5％的失重温度高于266°C。阻燃性能由TGA估算，所有计算得出的极限氧指数（LOI）值均超过24，这意味着固化膜具有出色的阻燃性。
