摘要
本文研究和讨论了木材的主要化学组分的热解性质及其与木材燃烧和阻燃的关系,反应型木材阻燃剂与木材各组分的反应途径,指出200～300℃是阻燃剂促进木材脱水成炭、发挥阻燃作用的关键温度。文中还分析了木材阻燃技术的发展方向,指出反应型木材阻燃剂是解决阻燃剂吸潮和流失问题的有效途径,纳米阻燃是亟待开发的高效阻燃技术,一剂多效的膨胀型阻燃剂是阻燃剂的发展方向之一。
The flame retardancy of wood is based on its chemical composition and structure. The objective of this study was to explore the (relationship) between the primary chemical properties of wood composition and its pyrolysis and combustion and to analyze the reaction path between the (reacting) flame retardants and wood composition. The conclusion showed that the key point was (temperature) at 200～300 ℃ where the flame retardant was able to promote dewatering and (charring) of wood. It also showed that a reacting type flame retardant was an efficient way to prevent the preservative from leaching. Finally, some suggestions for flame retardancy were made, such as (applying) Nanometer technology for wood flame retardant development and for exploring a versatile, efficient frothing type flame retardant.
