This surface reaction has the advantage of a nonblooming effect and an application in thermosetting plastics, Metal complexes have the effect of reducing the amount of smoke. Therefore, in the second step, transition-metal complexes were synthesized on the viscose rayon ammonium phosphate felt. This article focuses on the surface modification of phosphates and metal complexes on viscose rayon. All reactions were confirmed by attenuated total reflectance Fourier transform infrared and time-of-flight secondary ion mass spectrometry. As the concentrations of phosphoric acid and urea increased, the peak intensities of ammonium ion groups and phosphate groups greatly increased. The thermal properties of the synthesized materials were studied with thermogravimetric analysis and oxygen index testing. On the basis of the experimental results, the synthesized flame-retardancy materials showed excellent physicochemical and thermal effects and flame retardancy. (C) 2000 John Wiley & Sons, Inc.
