Abstract P(AN-co-MA-co-MMA)@H₂O microcapsule foaming agent was synthesized via inverse suspension polymerization under constant pressure, and then P(AN-co-MA-co-MMA)@H₂O microcapsule/melamine resin foam composite material was further obtained. Specifically, the apparent density, foam structure, closed porosity, flame retardancy and compressive strength of the prepared composite material were studied in detail. In addition, the comparison in properties between the prepared composite material and melamine foams synthesized by using isooctane and isooctane microcapsules as foaming agents was conducted. It can be found from the results that the P(AN-co-MA-co-MMA)@H₂O microcapsule/melamine resin foam with an apparent density of 30 kg/m³ was acquired, and it exhibited amazing physical properties with closed porosity of 91%, water absorption of 92% and compressive strength of 143 kPa. Besides, the limit oxygen index (LOI) of P(AN-co-MA-co-MMA)@H₂O microcapsule/melamine resin foam (36%) presented a remarkable increase compared with that of isooctane melamine foam (29%) and isooctane microcapsule/melamine foam composite (28%). Moreover, the residual amount of the composite material after combustion was 10%, which is obviously higher than that of the other two kinds of melamine foam.

Key words： microcapsule melamine resin foam flame resistance limit oxygen index compressive strength closed porosity
