摘要

本試驗係探討膠合劑對經由五種熱壓溫度所製造的杉木蒸煮處理熱壓縮材接合強度之影響，以尋求最適合蒸煮處理熱壓縮材供為家具材料時之製造條件及膠合劑。試驗結果顯示，杉木蒸煮處理熱壓縮材使用五種膠合劑接合，以瞬間接著劑之接合強度最強，乃以白膠最弱。而使用較高熱壓溫度條件（如160℃、170℃）所製造之材料，不論是引拔強度或破壞撓矩皆較差。至於膠合劑對以不同熱壓溫度製備之材料的適合性分別如下：引拔強度方面一除了六馬膠以接合於熱壓溫度為130℃所處理者之強度最佳外；其餘四種膠合劑皆為140℃。而破壞撓矩與接合效率方面－六馬膠亦以130℃處理者最強：白膠為140℃；但架橋式白膠、變性白膠及瞬間接著劑等則均為150℃。

The purpose of this study is to investigate the influence of adhesives on the joint strength of China fir heat-stabilized compressed wood manufactured with five kinds of hot press temperature, and to find out the most suitable production condition and adhesives for heat-stabilized compressed wood in the use of furniture materials. The experimental results reveal that China fir heat-stabilized compressed wood jointed with cyanoacrylate have the best joint strength, while PVAc is the weakest. The materials with highest hot press temperature (as 160 DC, 170 DC) either withdrawal strength or bending moment is the weakest. Regarding the adaptability for adhesives to materials manufactured with different hot press temperature as followings: For withdrawal strength - the suitable hot temperature for UF glue is 130°C, while the others are 140 DC. For bending moment - the suitable hot press temperature for UF glue is also 130°C, PVAc is 140°C and 150°C for cross-linking PVAc, modification PVAc and cyanoacrylate.
