Abstract
A biodegradable polyurethane plastic is provided. The biodegradable polyurethane plastic includes biodegradable polyurethane impregnated with a phosphorus-containing additive, wherein the additive includes phosphorus pentoxide (P2O5), and the additive is coated with natural oil. The biodegradable polyurethane plastic has excellent physical properties, and can be effectively decomposed in a short period of time because it includes biodegradable polyurethane impregnated with a phosphorus-containing additive. Further, the biodegradable polyurethane plastic can be easily decomposed biologically by synthesizing polyurethane containing phosphorus pentoxide having strong oxidizing action, can be manufactured by directly adding an additive coated with natural oil to the synthesis of polyurethane, can prevent the reaction caused by moisture because it does not come into contact with air, and can prevent a color change.
