| 中文摘要 | 本試驗製備出的鉬改質酚醛樹脂(Mo-PF),在製備過程中鉬酸鹽與酚醛樹脂(PF)反應後形成具有 Mo-O鍵結的低交聯度鉬酚醛樹脂,然後再進一步與六亞甲基四胺(hexamethylenetetramine)混合後,經由 190 oC熱固化後形成熱固性鉬改質酚醛樹脂。 Mo-PF樹脂與 PF樹脂藉由 FTIR、DSC、DMA、TGA、SEM及抗彎曲強度測試後,可觀察到 Mo-PF的熱性能及機械強度都明顯高過 PF樹脂。由於 Mo-PF樹脂結構中形成的 Mo-O鍵結,因此 Mo-PF樹脂在 10%熱重量損失溫度及抗彎曲強度分別為 503 oC、76.5 MPa,其熱性能及機械強度高過 PF樹脂的( 439 oC、53.7 MPa)。另一方面,藉由 Mo-PF及 PF樹脂做為黏結劑分別製作鑽石研磨工具,從氧化鋁陶瓷研磨試驗中觀察鑽石研磨工具表面的研磨狀態,其試驗結果的比較及觀察 Mo-PF具有良好的耐熱性能及研磨品質。 |
| 英文摘要 | Novolac molybdenum modified phenolic resins (Mo-PF) were successfully prepared. In the process of preparation, molybdate reacted with phenolic resins (PF) to form a low cross-linked Mo-PF with new Mo-O bonds, and it was confirmed by the FTIR spectrum. The Mo-PF can be further cured with hexamethylenetetramine at 190oC. The structure and characterization of PF and Mo-PF were performed by using FTIR, DSC, DMA, TGA, SEM, mechanical strength tester. The thermal resistance, flexural strength, and hardness of Mo-PF are respectively higher than those of PF. This is due to the presence of Mo-O cross-linking bonds in Mo-PF. The thermal decomposition temperature at 10% weight loss and flexural strength of Mo-PF are 503oC and 76.5MPa respectively, which are much higher than the corresponding values of 439oC and 53.7MPa for PF. Furthermore, in order to identify the applied properties of Mo-PF resin, it was compared with PF in the performance as a binder for diamond grinding tools through the basic grinding experiments of Al2O3 ceramics. Mo-PF is a better binding resin than PF so the grinding tool made from the former resin has better grinding quality than that made from the latter resin. |
