This experiment uses polypropylene fibers, PU foaming agent, and an unsaturated polyester resin, fixed to amount of resin and the plate thickness, change the amount of the polypropylene fibers and PU foaming agent, mixture and made the composite sound absorbing plate, we text this plate material mechanical properties and acoustic effect, compared to the lead plates of sound-absorbing materials on the market due to the absorption of water loss, shorter life issues. Hope to be able to produce excellent physical properties, long service life and good sound-absorbing composite plates.
本實驗使用聚丙烯纖維、PU發泡劑及不飽和聚酯樹脂,固定樹脂用量以及板材厚度,改變聚丙烯纖維與PU發泡劑之用量,混和製成複合吸音用板材,並對於此板材進行機械性質及吸音性的相關測試。相較於現在市面上的吸音材料因吸收水分導致板材損耗,本實驗結果發現使用聚丙烯纖維、PU發泡劑及不飽和聚酯樹脂所做出來的PP/PU複合板材其密度介在0.46至0.56之間,且能夠有極低的含水率,約0.48%-0.51%;在吸音測試中,最高吸音率也能夠達到吸音率0.6以上,是良好的吸音材料。
