Study of preparation and modification and properties of melamine formaldehyde resin foam

Melamine formaldehyde (MF) foam is one autologous fire-retardant material which can be easily self-extinguished without producing toxic drips during combustion, it can be used as thermal insulation and sound-absorption material and has a bright future. However, the shortcomings such as large fragility restrict its wider application. In this paper, we discussed the differences between morphology and compressive modulus in different ways of foaming and then the influence on foam morphology of foaming agent as well as the effect on the properties with the addition of PVA which has good flexibility, then analyzed its fire-retardant, mechanics and thermal insulation properties using LOI, compression and coefficient of thermal conductivity test respectively.
