Study on degradation of phosphorus and nitrogen composite UV-cured flame retardant coating on wood surface

A novel wood flame retardant coating has been obtained using acrylate oligomers and functional monomers containing elements phosphorus, nitrogen and sulfur as raw materials and applied on the wood surface based on thiol-ene click reaction. The UL-94, limiting oxygen index (LOI) test and thermal gravimetric analysis/infrared spectroscopy (TGA-FTIR) were used to examine the flammability and pyrolysis property of the coatings, respectively. The...
