摘要


本研究利用鋅粉、鋁粉與有機矽烷分別當發泡劑與改質劑,進行化學發泡製作輕質多孔無機聚合物牆板,研究發現隨著鋅粉或鋁粉添加量增加,熱傳導係數與抗壓強度皆下降。鋅粉搭配有機矽烷後可有效控制無機聚合物孔洞均勻度,因此可降低熱傳導係數至0.113W/m.K並具有適當抗壓強度值約36.67 kgf/cm2,所製得的多孔性無機聚合物達到輕質、高隔熱的效果。

In this study, zinc and aluminum powders were used as foaming agents and organosilane was innovatively used as a modifier to synthesize a chemically foamed geopolymer used as lightweighted, porous wall. With increasing the amounts of zinc or aluminum powders, thermal conductivity and compressive strength were decreased. Zinc powders accompanied with organosilane made the foamed geoplymer with uniform pore size distribution, which reduced thermal conductivity to 0.113W/m.K, and proper compressive strength about 36.67 kgf/cm2. The produced foamed geopolymer with enhanced compressive strength and low thermal conductivity is an ideal material for fire protection, sound absorption and thermal insulation.
