The invention discloses a mixed plant-based polyurethane porous material impregnated with carbon nanotubes and graphene oxide. The polyurethane sound-absorbing material is prepared by using castor oil polyol and rosin ester polyol instead of petroleum-based polyol. The material has a wide range of sources and is easy to degrade. Environmental pollution is reduced, and the addition of carbon nanotubes increases the weight of the material under the same volume, which further enhances the high-frequency sound absorption effect of the material. The impregnation of graphene oxide increases the complexity of the material inside, making it have better mid-low frequency Sound absorption and compression properties. At the same time, the present invention also provides a method for preparing a mixed plant-based polyurethane porous material impregnated with carbon nanotubes and graphene oxide. Different stirring speeds are used in the material preparation process to ensure that the materials are evenly mixed, and the heat preservation treatment and drying treatment are given. The appropriate temperature value at the time and the effective temperature control not only ensure the foaming effect and drying effect, but also ensure the sound absorption and compression properties of polyurethane materials.
