将季戊四醇三丙烯酸酯（PETA）和聚二甲基硅氧烷（PDMS）引入水性聚氨酯的主链，制得硅氧烷改性的UV固化水性聚氨酯乳液，通过FTIR红外光谱对乳液的结构进行表征。将该乳液与助剂复配，制得水性塑料涂料，并对涂层的固化动力学和表面性能进行研究。与未改性的涂料相比，硅氧烷改性的UV固化水性涂料具有良好的耐水性和耐溶剂性，同时保留了优良的手感，可用作水性柔感塑料涂料。
將季戊四醇三丙烯痠酯（PETA）和聚二甲基硅氧烷（PDMS）引入水性聚氨酯的主鏈，製得硅氧烷改性的UV固化水性聚氨酯乳液，通過FTIR紅外光譜對乳液的結構進行錶徵。將該乳液與助劑複配，製得水性塑料塗料，併對塗層的固化動力學和錶麵性能進行研究。與未改性的塗料相比，硅氧烷改性的UV固化水性塗料具有良好的耐水性和耐溶劑性，同時保留瞭優良的手感，可用作水性柔感塑料塗料。

A polysiloxane modified UV curable waterborne polyurthane emulsion was prepared by introducing pentaerythritol triacrylate （ PETA ） and polydimethylsiloxane （ PDMS ） into the main chain of polyurethane prepolymer. The structure of emulsion was characterized by Fourier transform infra-red （ FTIR ）. The synthesized emulsion were mixed with additives to obtain waterborne plastic coatings. The curing kinetics and the surface properties of coatings were investigated. Compared unmodified coatings, polysiloxane modified UV curable waterborne polyurethane coatings exhibited better water/solvent resistance and showed excellent soft-feeling, which could be used as waterborne soft-feel plastic coatings.
