中文摘要 | 本研究的目的是以甲苯二異氰酸酯系統的聚氨酯,藉由配方及結構的變化,採用灌注型的預聚合物法,製成甲苯二異氰酸酯彈性體、甲苯二異氰酸酯微球彈性體及不同硬度甲苯二異氰酸酯彈性體堆疊三種材質,各分別製備數種不同硬度的滑板避震墊,並進行相關測試分析和研究。研究結果顯示,一、相同材質硬度高的避震墊,其壓縮 50%最大荷重、強度、韌性也較高、其中硬度 95 A的甲苯二異氰酸酯彈性體有最佳的壓縮 50%最大荷重 110.78kgf及強度 7.84kgf/cm2,硬度 90 A的甲苯二異氰酸酯彈性體則有最佳的韌性 14766kgf*mm。二、相同材質硬度高的避震墊,其壓縮能量、恢復能量、滯後能量損失率也較高,其中以硬度 95 A的甲苯二異氰酸酯彈性體最大,各項測試值依序為 236kgf、130 kgf及55.28%。三、實際測試,硬度高的避震墊有較佳的支撐性,硬度適中則操控性佳,其中以硬度 95 A的甲苯二異氰酸酯彈性體支撐性最好,甲苯二異氰酸酯微球彈性體有較好的避震性,甲苯二異氰酸酯彈性體堆疊則具備可同時擁有操控性與支撐性的潛力。 |
英文摘要 | The aim of this research was to adopt the TDI system of polyurethane by means of the prescription and changes of structure, utilizing the polymer method to manufacture TDI foam elastomer and different levels of the hardness of TDI elastomer accumulating three types of materials; each of these was respectively prepared to produce different levels of the hardness of skateboard cushion pads. The relevance of this process was examined and analyzed. The results were as follows: (1)For the same material with the high hardness of cushion pads, the maximum compression of 50% load, strength and toughness appeared to be higher, and among these, the hardness of 95 A TDI elastomer revealed the best, whereby the test outcomes were 110.78kgf, 7.84kgf/cm2 and 13554kgf * mm. (2)For the same high hardness material of cushion pads, the compression energy, reversion energy, and the rate of lost energy also appeared to be higher; among these, the 95A hardness of TDI elastomer revealed the best, whereby the test outcomes were 236 kgf, 130kgh and 55.28%. (3)For the experimental test, the high hardness of cushion pads appeared to have better sustainability, appropriate hardness and well operation; among these, the 95A hardness sustain of TDI elastomer revealed the best. Besides, TDI foam elastomer appeared to be better cushion, and the accumulation of TDI elastomer simultaneously possessed the potential of both operation and sustainability. |
