摘要

本碩士論文的研究主軸在將廢棄之矽鋸粉經球磨加工後，作為微米級填料進一步導入熱固性環氧樹酯中，來提升此樹酯之防腐蝕性能。 首先，將由達興材料公司所提供的廢棄矽鋸粉藉由5 mm及10 mm大小的鋯珠進行球磨，將矽鋸粉之粒徑降低以提升粉體之表面積，緊接著藉由熱固化法將廢棄的矽鋸粉導入環氧樹酯中以形成有機/無機混成複合材料，並利用電化學法量測矽鋸粉/環氧樹酯之高分子微米複合材料防腐蝕塗料的應用性。
製備一系列不同矽鋸粉大小及濃度的矽鋸粉/環氧樹酯複合塗料，並利用電化學法量測此複合材料塗佈在冷轧鋼片上之防腐蝕性能。 研究結果顯示，矽鋸粉/環氧樹酯高分子微米複合材料在防時性能上或的三個結論: (1) 環氧樹酯有導入矽鋸粉較單純高分子塗料有較佳的防腐蝕能力; (2) 在相同的矽鋸粉添加量下，複合塗料添加有球磨矽鋸粉較添加無球磨矽鋸粉的防蝕效果好; (3) 複合塗料添加的矽鋸粉的含量越多，防蝕效果越好。

The main target of this dissertation is to prepare the composite coatings containing waste silicon sawdust, followed by applied as an anticorrosion coatings. First, the waste silicon sawdust provided by company was beads-milling process with Zr beads in the diameter of 5 mm and 10 mm. Subsequently, the as-prepared silicon sawdust was introduced into epoxy resin coating by performing the thermally ring-opening polymerization reactions. A series of electrochemical corrosion measurements were performed to investigate the as-prepared composite coatings containing epoxy resin and waste silicon sawdust.
It should be noted that the anticorrosion studies of composite coatings have drawn three conclusions: (1) Composite coatings showed better anticorrosion performance than neat epoxy coating. (2) At same feed loading, composite coatings containing grounded silicon sawdust showed better anticorrosion performance than that containing non-grounded sawdust. (3) Composite coatings with higher loading of silicon sawdust exhibited better anticorrosion performance.
