摘要

本研究以亞麻仁油為基質，添加不同重量比之竹焦油（竹焦油／亞麻仁油=0/100、5/100及10/100）及不同乾燥劑配方（鈷／鋯／鈣%=1.0/1.0/1.0、1.5/0.75/0.75及2.0/0.5/0.5%，對亞麻仁油重量比），於大氣環境中加熱至140℃並持溫3hr後，製成滲透型竹焦油／亞麻仁油塗料，探討其作為戶外用木材塗料之可行性。試驗結果顯示，以竹焦油／亞麻仁油=5/100之塗料於乾燥後具有較高之塗膜硬度，且鈷／鋯／鈣乾燥劑比例為1.5/0.75/0.75%者具有最均衡之塗膜性質及耐光性。由純亞麻仁油塗裝者之塗膜耐光性不佳，但添加竹焦油後可明顯增加塗膜耐候性，竹焦油含量愈高及塗布量愈高（50-250 g/m^2），塗裝材之耐腐朽性愈佳，經戶外耐候試驗後，塗膜外觀更顯明亮。

In this study, the penetrating type linseed oil-based bamboo tar wood coatings were prepared by mixing different weight ratios of bamboo tar/ linseed oil of 0/100, 5/100 and 10/100, with different driers formulations of Co/Zr/Ca% of 1.0/1.0/1.0, 1.5/0.75/0.75, and 2.0/0.5/0.5% by weight of linseed oil, respectively; the mixtures were heated to 140℃ at atmosphere environment for 3 hr. The feasibility of the coating used for outdoor wood coating was assessed. The results showed that the coating with bamboo tar/linseed oil of 5/100 had higher film hardness and the coating containing the dryer with Co/Zr/Ca% of 1.5/0.75/0.75% had the best balance between film properties and lightfastness. The film of linseed oil alone had poor lightfastness, however, the weather resistance of the film could be improved by adding bamboo tar. Furthermore, the more added bamboo tar and spray amounts of wood coatings (50-250 g/m^2), the superior decay resistance obtained and the films became more brightness after outdoor weathering test.
