中文摘要 | 本材是一相當優質的天然有機材料,惟燃燒性卻成為其一大缺點。木材在150℃即開始軟化、熱分解,引火溫度260~300℃,發火溫度400~450℃,所以需要有特殊技術配製低溫發泡的火塗料才具有真正的保護作用。本研究乃利用特殊的技術調配防火塗料,期能滿足下列的需求:1、省資源:達到標準耐燃級數的最少塗佈量(公克/坪)。2、環保性:水性防火塗料要符合世界性環保標章的規格;而油性防火塗料則使用KB值28,芳香烴(苯類)含量0.001wt%之無毒、無味溶劑。3、安全性:火災現場,其燃燒產生之濃煙氣體是威脅生命安全的主因。本研究以特殊技術配製的防火塗料,依CNS6532耐燃一級測試可達無煙的防火特性(即發煙係數CA為0),另一種微煙防火塗料之發煙係數CA為12.6~23.5,符合CNS6532耐燃一級發煙係數CA=30或以下之標準。4、耐久性:本研究之防火塗料經室外曝露一年以上及加速耐候試驗(相當於室外曝露20年),其防火性能並無改變,即仍保持其原有優異之防火功能。 |
英文摘要 | Wood is a kind of very special unique natural organic construction material, however, it has the fatal defect of combustion. As wood begins to thermal degrades at 150℃, ignites at 260~300℃ and burns at 400~500℃, it needs the real protective flame retardant coatings which derives from the special technology. In this study, the flame retardant coatings meet the following requirements: 1、material saving: the minimum coating spread rate g/m2 for reaching fire endurance grade. 2、environmental friendly: the water-borne flame retardant coatings meet the requirements of worldwide ecolabel (green mark), and the odorless、non-toxicity solvent, which has KB Value 28 and aromatic content 0.001wt%, was applied to prepare the solvent-base flame retardant coatings. 3、safety: smoke is the fatal fact to cause people death. The non-smoke flame retardant coatings has the characteristics of fuming factor CA=0, and the fuming factor CA=12.6~23.5~ of the other flame retardant coatings shows its small smoke generation. 4、edurance: the flame retardant coatings still maintain their fire-proofing properties after one year outdoor exposure or accelerated weathering test (about to 20 years). |
