In this article, two kinds of phosphorus-containing cardanol-based acrylates were designed and synthesized. Firstly, a pre-polymer (PT-HCE) with three arms was synthesized using hydroxyethyl cardanol ether (HCE) and phosphorus oxychloride (POCl₃) as raw materials. Then, the PT-HCE was acrylated to synthesize phosphate tris-hydroxyethyl cardanol epoxy acrylate resin (AEPT-HCE) and phosphate tris-hydroxyethyl cardanol photosensitive resin (APT-HCE). The structures of PT-HCE, AEPT-HCE and APT-HCE were characterized and the results showed that the photosensitive resins were successfully synthesized. In addition, AEPT-HCE and APT-HCE were used to prepare the flame-retardant UV/EB curing coatings. The properties of the coatings were tested, and the results revealed that different structures have a certain effect on T_g and tensile properties of the coatings. The cured films demonstrated excellent flame-retardant properties, showing flammability rating of V-0 in UL-94 test.

本文设计并合成了两种含磷腰果酚基丙烯酸酯。首先，使用羟乙基腰果酚醚 (HCE) 和三氯氧磷 (POCl ₃ ) 合成了具有三臂的预聚物 (PT-HCE)。) 作为原料。然后，将PT-HCE丙烯酸酯化合成磷酸三羟乙基腰果酚环氧丙烯酸酯树脂（AEPT-HCE）和磷酸三羟乙基腰果酚光敏树脂（APT-HCE）。对PT-HCE、AEPT-HCE和APT-HCE的结构进行了表征，结果表明光敏树脂合成成功。此外，AEPT-HCE和APT-HCE用于制备阻燃UV/EB固化涂料。对涂层的性能进行了测试，结果表明不同的结构对涂层的T _g和拉伸性能有一定的影响。固化后的薄膜表现出优异的阻燃性能，在 UL-94 测试中显示出 V-0 的可燃性等级。
