Thermal Decomposition of Wood Treated with K₂CO₃ and Melamine Modified Phenolic Resin by Thermogravimetry–Mass Spectrometry

Abstract:

The flame retardancy of the wood samples treated with K₂CO₃, melamine modified phenolic resin (MMPR), and their mixture of K₂CO₃/MMPR was studied with the limiting oxygen index (LOI) method. The thermal degradation process and the composition of the products in gas phase were determined by the thermogravimetry–mass spectrometry (TG–MS) analysis methods. The results showed that the K2CO3 accelerates the dehydration reaction of wood and promote the formation of more H₂O, CO₂, and char residue, while MMPR can act as the thermal barrier during the combustion of the samples. When the wood sample treated with K₂CO₃/MMPR, there are the catalysis of K₂CO₃ and the adiabatic effect of MMPR make the samples have better flame retardancy.
