We synthesized the urethane/siloxane acrylate oligomer from isophorone diisocyanate (IPDI), hydroxyl alkyl terminated polydimethylsiloxane and 2-hydroxyethyl acrylate (2-HEA). UV-curable resins were formulated from the synthesized oligomer, ethylene glycol phenyl ether acrylate (PHEA), 1,6-hexanediol diacrylate (HDDA), trimethylolpropane triacrylate (TMPTA) as a reactive diluent, 3-isocyanato-1-propene as an adhesion promoter and photoinitiators. The PET film was treated with plasma in order to introduce the functional group on the PET surface and the functional group was observed through X-ray photoelectron spectroscopy (XPS) and the Fourier transform infrared (FT-IR). The adhesion strength between the PET film and the UV-cured resin were increased by using the adhesion promoter. Also, the thermal stability, the modulus and surface hardness were increased, as the adhesion promoter was added.
我们以异佛尔酮二异氰酸酯（IPDI）、端羟基聚二甲基硅氧烷和丙烯酸-2-羟乙酯（2-HEA）合成了聚氨酯/硅氧烷丙烯酸酯低聚物。由合成的低聚物、乙二醇苯基醚丙烯酸酯（PHEA）、1,6-己二醇二丙烯酸酯（HDDA）、三羟甲基丙烷三丙烯酸酯（TMPTA）作为反应性稀释剂、3-异氰酸根合-1-丙烯作为附着力促进剂和光引发剂配制了紫外光固化树脂。对PET膜进行等离子体处理，以便在PET表面引入官能团，并通过X射线光电子能谱（XPS）和傅里叶变换红外光谱（FT-IR）观察官能团。使用附着力促进剂提高了PET膜与紫外光固化树脂之间的附着力。此外，添加附着力促进剂后，热稳定性、模量和表面硬度均有所提高。
