Abstract

Polyurethane foam is a commonly used filler material in daily life, so its mechanical properties and flame retardancy are important research. Therefore, this study used rigid polyurethane foam add alginate powder, in which different alginate powders (calcium alginate, copper alginate and zinc alginate) were added to the polyurethane foam in a fixed proportion. Useing the flame retardant properties (LOI), sound absorption properties and impact resistance to find the best alginate powder. Because polyurethane is a flammable polymer structure, flame retardant is usually added to improve its performance in the process. In this experiment, the alginate is used to improve the performance of the polyurethane structure by using its flame retardant mechanism. Tests have shown that the addition of alginate can improve the impact resistance, most notably zinc alginate, which can absorb 89% of the impact. In the performance of sound absorption performance, each powder has different applicable frequency. Copper alginate and zinc alginate have better sound absorption effect at 1500-2000 Hz, while calcium alginate is at 2500-3000 Hz.

摘要

聚氨酯發泡為日常生活中常用的填充材料，因此其力學性能及阻燃性能為重要之研究。所以本研究選用硬質聚氨酯發泡添加海藻酸鹽粉體，其中使用不同海藻酸鹽粉體(海藻酸鈣、海藻酸銅及海藻酸鋅)依固定比例添加製聚氨酯發泡中。觀察其阻燃性質(LOI)，吸音性質及抗衝擊性能，並找出最佳海藻酸鹽粉體。因聚氨酯為易燃的高分子結構，在其製程當中通常會加入阻燃劑以提高其性能，本實驗以試添加海藻酸鹽利用其阻燃機制來提高聚氨酯結構的性能。經測試表明添加海藻酸鹽類皆能使抗衝擊性能提高，最為顯著的為海藻酸鋅，能吸收89 %的衝擊力。在吸音性能的表現上各粉體有不同適用的頻段，海藻酸銅與海藻酸鋅在1500-2000 Hz有較佳之吸音效果，而海藻酸鈣則為2500-3000 Hz。
