摘要

本研究以四種商業化奈米矽酸鹽混摻來增進EVA微孔塑膠材料於相似之發泡倍率下之機械特性，以強化此一微孔塑料物性並提升其應用領域，實驗上採用不同有機插層改質劑進行奈米化改質層狀矽酸鹽、塑膠配方調控與混摻加工製程等技術開發，以形成矽酸鹽強化之奈米材料，並進行架橋及發泡特性評估以及機械性質之測試。結果表明添加奈米化層狀矽酸鹽對於EVA發泡系統有良好之補強插層分散效果。機械性質方面，試片44-5爲最佳補強，其比拉伸強度增加16%，比模數增加82%，比撕裂強度增加35%。

In this study, layered nanosilicate reinforced EVA form materials were developed by four commercialized organosilicates to enhance the physical and mechanical properties of EVA foams and to broaden their application fields. The microstructure, crosslinking, foaming, physical and mechanical properties of EVA foam materials were investigated. X-ray diffraction results proved that an intercalated microstructure of EVA form nanomaterial was obtained with the aid of formulation design and blending condition control. The optimized specimen with the excellent properties could be found by adding 5 wt% I.44P organosilicate. The specimen has 16%, 82% and 35% increase on the specific strength, specific modulus and specific tear strength compared to the pure EVA foam.
