Abstract
In this study, the best flame retardant/hollow composite base fabric was combined with rigid polyurethane foam to change the foaming density to 60, 70 and 80 kg/m3 respectively. Finally, the effects of different foaming densities on the compressive strength test, the drop weight impact strength test and the sound absorption test were investigated. The test results show that the mechanical properties of the flame retardant non-woven composite polyurethane foam are not significantly improved, because the foaming density mainly affects the results. The flame retardant non-woven composite polyurethane foam is selected as the optimum composite
Keywords摘要
本研究選用最佳阻燃/中空複合基布與硬質聚氨酯發泡複合,改變其發泡密度分別為60、70、80 kg/m3。最後以壓縮強力測試、落重式衝擊強力測試及吸音測試進行探討不同發泡密度對於其之影響。經測試結果表明,阻燃不織布複合聚氨酯發泡的機械性能沒有明顯提升,因為主要是發泡密度影響其結果,經測試評估選出阻燃不織布複合聚氨酯發泡在密度60 kg/m3時為複合最佳參數。
