High-density melamine foam and preparation method thereof

摘要

The present invention discloses high-density melamine foam, which comprises the following raw materials; a primary polymer of waterborne melamine formaldehyde resin, solid methylol melamine, a polar solvent, a surfactant, a foaming agent, a curing agent and an additive. The present invention also discloses a preparing method of the high-density melamine foam, comprising the following steps: preparing a primary polymer of waterborne melamine formaldehyde resin; uniformly mixing the primary polymer of the waterborne melamine formaldehyde resin, the polar solvent, the surfactant and the additive to obtain a mixture A; uniformly mixing the mixture A with the solid methylol melamine to obtain a mixture B; uniformly mixing the mixture B with the foaming agent to obtain a mixture C; uniformly mixing the mixture C with the curing agent to obtain a mixture D; and carrying out microwave radiation, foaming, curing, drying and quenching on the mixture D in a microwave foaming device to obtain the high-density melamine foam. The melamine foam described in the present invention has high density and high strength performance.
