Beschreibung
Zusammenfassung:	The invention belongs to the field of functional polymer materials, and relates to preparation of compound polyurethane foam, in particular to a preparation method and application of hollow MnO2@SiO2 nanomaterial modified polyurethane foam. The method comprises the steps of preparing iron oxide by a hydrothermal method, wrapping silicon dioxide by a template method, preparing MnO2@SiO2 by the hydrothermal method, performing modification by using a silane coupling agent KH570 to form a hydrophobic and oleophylic modified MnO2@SiO2 nanomaterial, and finally, uniformly dispersing the modified MnO2@SiO2 nanomaterial in polyurethane foam for free foaming to form the polyurethane foam with good oil absorbency. The hollow MnO2@SiO2 nanomaterial-polyurethane foam 3D (three dimensional) oil absorption material with a 3D porous structure is obtained by compounding the hydrophobic modified hollow MnO2@SiO2 nanomaterial and the polyurethane foam material; the hydrophobicity of a polyurethane material is improved obviousl
