Abstract

This work combines guanidine dihydrogen phosphate (GDP) and zinc borate (ZB) to modify wood via microwave-ultrasonic impregnation for realizing favorable flame retardancy and thermal stability, which were investigated by the limiting oxygen index (LOI), thermogravimetric analysis (TGA), and cone calorimetry tests (CONE). The treated samples show better performance in fire retardancy with the LOI value increasing to 47.8%, and the results of TGA indicate the outstanding thermal stability of wood. In addition, the decline of heat release rate, total heat release, smoke production rate, and total smoke production examined by CONE further demonstrates the achievement of excellent flame retardancy and smoke suppression properties of the GDP/ZB-modified wood.

摘要

这项工作将磷酸二氢胍（GDP）和硼酸锌（ZB）结合起来，通过微波-超声浸渍对木材进行改性，以实现良好的阻燃性和热稳定性，并通过极限氧指数（LOI）、热重分析（TGA）和锥形量热测试（CONE）对其进行了研究。处理后的样品在阻燃性方面表现出更好的性能，极限氧指数值提高到47.8%，热重分析结果表明木材具有出色的热稳定性。此外，通过锥形量热测试检测到的热释放速率、总热释放量、产烟速率和总产烟量的下降，进一步证明了GDP/ZB改性木材具有优异的阻燃和抑烟性能。
