摘要：The thermal treatment and resin modification were employed to improve the thermal shrinkage resistance of the melamine foam in this paper. The result indicated that both of this two methods could improve the thermal shrinkage resistance of MF. The minimum contraction percentage were 0.07% and 0.5%, when the conditions were the thermal treatment at 200°C for 40 h and 3% phenolic formaldehyde resin(PF) treatment at 150°C for 0.5 h, respectively. The result of FTIR spectrum proved the mechanisms that the reaction of free functional group in MF, –NH2 and –CH2OH, formed a novel cross-linking of –NH–CH2–, which increased the degree of crosslinking of the MF and improved its shrinkage resistance on heat. However, the effect of the PF on MF was covering a layer of stable PF to enhance the strength of the foam structure and reduce the thermal shrinkage resistance, and its effect was a little inferior. © 2017 International Committee on Composite Materials.
