The traditional rigid polyurethane foaming plastic is naturally degraded for 200 years, which causes increasingly obvious white pollution problem. The raw materials of the degradable rigid polyurethane foaming plastic comprise a component A and a component B, wherein the component A comprises 200 parts by weight of biobased polyether glycol, 0.05-3.0 parts by weight of organic amine, 0.05-1.5 parts by weight of organic tin, 1-3 parts by weight of silicone oil, 0.5-5.0 parts by weight of distilled water and 5-10 parts by weight of microcrystalline cellulose; and the component B comprises 100-200 parts by weight of isocyanate. The component A is uniformly mixed into a material A and the component B is uniformly mixed into a material B, and the materials A and B are respectively packaged. The invention also discloses a foaming method of the raw materials. The foaming raw materials of the degradable rigid polyurethane foaming plastic has convenient preparation, storage and transportation and use; and the degradable rigid polyurethane foaming plastic prepared by the raw materials can be naturally degraded about 3 years in natural state after being discarded.
