Novel high-resilience load-bearing foam material and preparation method thereof

The invention discloses a novel high-resilience load-bearing foam material. The novel high-resilience load-bearing foam material is prepared from raw materials as follows: expandable melamino-formaldehyde resin, elastomer rubber or resin, a surfactant, a nucleating agent, a foaming agent and a vulcanizing agent. The invention further discloses a preparation method of the novel high-resilience load-bearing foam material. The preparation method comprises the following steps: the expandable melamino-formaldehyde resin is prepared; the elastomer rubber or resin, the surfactant, the vulcanizing agent and the nucleating agent are added, and an expandable melamino-formaldehyde resin-elastomer emulsion is prepared; the foaming agent and an acid catalyst are added, and a foaming solution is prepared; micorwave foaming and crosslinking are performed; high-temperature drying and curing are performed; quenching is performed at the normal temperature, and the novel high-resilience load-bearing foam material is obtained. The novel high-resilience load-bearing foam material has good flame retardancy, thermal stability, shock resistance and flexibility, high resilience and high indentation ratio, high porosity, high elasticity and better compression set resistance and repeated indentation fatigue performance than common melamine foam and touches fine.
