Method for preparing seat cushion based on soft melamine foam

The invention discloses a method for preparing a seat cushion based on soft melamine foam. The method comprises the following steps: (1) selecting the soft melamine foam with F/M of 1.5-2.5:1 for hotpressing, softening and baking to obtain the pretreated soft melamine foam; and (2) preparing the seat cushion by using the pretreated soft melamine foam. The pretreatment method enables the soft melamine foam which is not suitable for manufacturing the seat cushion or has poor performance to have good comfort, support, fatigue resistance and fireproof performance, so that the soft melamine foam is used for manufacturing seat cushions of office seats, public seats, automobiles, ships, rail vehicles and the like, and is particularly suitable for manufacturing aircraft seat cushions requiring light weight; and the method can meet the requirement of industrial production, and is beneficial to large-scale manufacturing. 本发明公开一种基于软质三聚氰胺泡沫制备座椅垫的方法，该方法包括：(1)选择F/M为1.5～2.5:1的软质三聚氰胺泡沫进行热压、柔化、烘焙得到预处理后的软质三聚氰胺泡沫；(2)用所述预处理后的软质三
