木材是最可持续、最美观、最环保的工程材料之一，经常用于建筑物的结构中。不幸的是，与木材相关的火灾危险限制了它的应用。透明纤维素纳米纤维(CNF)/粘土纳米复合材料具有独特的砖-砂浆结构，是一种可持续、高效的木材防火涂料。用锥形量热仪评价其着火性能。在典型的35kW/m(2)热流密度下，涂层木材的着火时间增加了约4 1/2min，而最大平均放热率(MARHE)降低了46%，从而显著降低了木材结构的潜在火灾威胁。(C)2015爱思唯尔有限公司。保留所有权利。
Wood is one of the most sustainable, esthetically pleasing and environmentally benign engineering materials, and is often used in structures found in buildings. Unfortunately, the fire hazards related to wood are limiting its application. The use of transparent cellulose nanofiber (CNF)/clay nanocomposites, with unique brick-and-mortar structure, is proposed as a sustainable and efficient fire protection coating for wood. Fire performance was assessed by cone calorimetry. When exposed to the typical 35 kW/m(2) heat flux of developing fires, the time to ignition of coated wood samples increased up to about 4 1/2 min, while the maximum average rate of heat emission (MARHE) was decreased by 46% thus significantly reducing the potential fire threat from wood structures.
