摘要

本實驗旨在提高水性PU樹脂抗紫外線的功能。其中以水性PU樹脂為基材，並添加具有抗紫外線功能的奈米微粒。本實驗中加入不同的奈米微粒，有二氧化鈦，二氧化矽，氧化鋅，分別添加至水性PU樹脂中並改變不同奈米微粒之添加量等變因，以探討不同奈米複合材料之抗紫外線效果及測試它們的物性變化。抗紫外線中，實驗結果顯示，水性PU樹脂分別添加不同奈米微粒時，其中奈米二氧化鈦抗紫外線效果最佳，遮蔽紫外線效果也最好，相反的則是二氧化矽對抗紫外線效果最差，遮蔽紫外線效果也最差。

The main Purport in this experiment is improving the function of the water-based PU to resisting the ultraviolet. The water-based PU is the based material with nanometer particles that has anti-uv function. In this experiment part add nanometer particles that has TiO2, SiO2 and ZnO to water-based PU, and change different nanometer particles quantity and Thickness PU resin/nanometer particle thickness, to discussion that the antu-uv ability with different nano composite and test the change of the physical properties. According to the result, water-based PU with three nanometer particles in various kinds of experiment turn into the reason, the nanometer TiO2 with the highest anti-uv ability and cover ability, in the other hand the nanometer SiO2 the with the worst anti-uv ability and cover ability is nanometer SiO2.
