摘要

以2, 4-甲苯二异氰酸酯、聚乙二醇和丙烯酸羟乙酯为原料合成了聚氨酯丙烯酸酯(PUA)预聚体，然后采用电子束辐射固化技术对PUA预聚体涂层进行固化研究，通过傅里叶红外光谱(FT-IR)和热重分析(TGA)等方法表征固化后PUA固化膜的结构和性质，并讨论了电子束吸收剂量与PUA固化膜性能之间的规律。结果表明，不同吸收剂量的PUA固化膜固化性能表现出明显的差异，在60−80 kGy范围内，PUA固化膜具有较好的力学性能、高的凝胶率和热稳定性。

Abstract

The PUA was prepared with 2,4-tolylene diisocyanate, polyethylene glycol, and hydroxyethyl acrylate. The electron beam was used to cure the coatings. The samples were characterized by FTIR and TGA to investigate the law of the absorbed dose and the properties of the products after electron beam curing. The results showed that the absorbed dose had great effects on the characterization of the cured PUA coatings, and the samples irradiated with dose of 60−80 kGy had good mechanical properties, high gel fraction and thermal stability.Cited
