摘要

本研究旨在探討木質材料經化學改良後之耐燃性、耐腐朽性與抗白蟻性。化學改良方法係將木材以硼酸/脂肪族有機胺（丙胺、丁胺、己胺及辛胺）、硼酸／芳香族有機胺（苯胺、對甲基苯胺、對甲氧基苯胺及對硝基苯胺）等組合藥劑反應而成。試驗結果顯示：木材以硼酸／有機胺等藥劑處理後並不能顯著地改善其耐燃性；木材以硼酸／辛胺、硼酸／對甲氧基苯胺、硼酸對硝基苯胺等藥劑處理具有較爲優異之耐腐朽性；木材以硼酸／辛胺、硼酸／芳香族有機胺等藥劑處理具有較爲優異之抗白蟻性；木材以硼酸／芳香族有機胺處理較之以硼酸／脂肪族有機胺處理具有較優異之疏水性；木材以硼酸／脂肪族有機胺處理較之以硼酸／芳香族有機胺處理具有較小之色變。

The purpose of this research was to evaluate the thermal properties and decay and termite resistance of chemically modified wood. The wood was chemically modified by reacting it with a combination of boric acid and aliphatic amines(propylamine, butylamine, hexylamine, and octylamine) and boric acid and aromatic amines(aniline, p-toludine, p-anisidine, and 4-nitroanoline). Results indicate that treating wood with boric acid and amines did not significantly improve its fire retardancy. Wood samples treated with boric acid/octylamine, boric acid/p-anisidine, and boric acid/4-nitroaniline were very resistant to decay fungi. Wood samples treated with boric acid/octylamine and boric acid/all 4 aromatic amine combinations were also very resistant to termites. Wood treated with boric acid/aliphatic amines. Wood treated with boric acid/aliphatic amine combinations resulted in less wood discoloration than that produced by with boric acid/aromatic amine treatments.
