Abstract | The invention discloses high-density soft melamine foam which comprises the raw materials of water-based melamino-formaldehyde resin initial polymers, solid hydroxymethyl melamine, a polar solvent, a surface active agent, a foaming agent, a curing agent and an adding agent. The invention further discloses a preparing method of the high-density soft melamine foam. The method comprises the steps that the water-based melamino-formaldehyde resin initial polymers are prepared; the water-based melamino-formaldehyde resin initial polymers, the polar solvent, the surface active agent and the adding agent are evenly mixed to obtain a mixture A; the mixture A and the solid hydroxymethyl melamine are evenly mixed, and a mixture B is obtained; the mixture B and the foaming agent are evenly mixed, and a mixture C is obtained; the mixture C and the curing agent are evenly mixed, and a mixture D is obtained; and the mixture D is subjected to microwave radiation foaming, solidifying, drying and quenching in a microwave foaming device in a microwave foaming device, and the high-density soft melamine foam is obtained. The melamine foam has high density and high strength performance. |
