| Abstract: | Melamine formaldehyde resin after dehydration and polyol were blended,and crosslinked by isocynante then composite foam was synthesized.The thermal stability of foams modified by polyurethane was studied by thermogravimetric analysis(TGA),and the results indicated that thermal degradation of the modified foams had three stages.The second decomposition temperatures of the foams modified by MDI type were much higher than the second decomposition temperatures of the foams modified by TDI type.The results from ... |
