本征阻燃型木材纤维的制备及其性能研究
Preparation and Properties of Intrinsic Flame-retardant Wood Fibers
摘要
Abstract
Aiming at the flammability issue of wood fibers,intrinsic flame-retardant wood fibers were prepared by modifying it with reactive ternary deep eutectic solvent(DES),and the influence of treatment temperature on fiber structure and properties was investigated.The chemical structure of flame-retardant modified wood fibers was characterized with Fourier transform infrared spectrometer(FT-IR),X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS),and scanning electron microscopy combined with energy dispersive spectroscopy(SEM-EDS).The thermal and flame-retardant properties of the fibers were also tested using thermogravimetric(TG),limit oxygen index(LOI)and cone calorimetry.The results indicated that P/N characteristic peaks appeared in the chemical structure of flame-retardant modified wood fibers,proving the successful grafting of reactive DES.With the increase of processing temperature,the residual carbon rate of wood fibers at 800℃gradually increased,the maximum heat release rate and total heat release gradually decreased.Compared with the unmodified wood fiber,the carbon residue rate of the modified sample at 130℃increased from 24.2%to 49.23%.The value of LOI increased from 20.7%to 46.3%with a rise of 123.7%.The maximum heat release rate and total heat release decreased from 126.8 W/g and 9.0 kJ/g to 22.7 W/g and 0.4 kJ/g,respectively.The flame-retardant properties of modified wood fibers had been significantly improved.关键词
