The invention discloses a preparation method of degradable plastics. S1: Send raw materials into a mixing cylinder, then start a driving motor to stir the raw materials, and heat the raw materials inside the mixing cylinder through a heating plate at the same time. S2: After stirring is completed, start a rotating motor, transmit power through the cooperation of driving wheels and a belt to drive a transmission rod to rotate, then drive a connecting rod and a spiral blanking plate to rotate through the cooperation of a driving gear and a driven gear, and send the stirred materials evenly into an extrusion pipe. The invention is provided with a convenient extrusion blow molding mechanism. The accumulation of solution inside the barrel pushes a pressure plate upward, and when the pressure plate pushes a top rod to fit a touch switch, the power supply to an electromagnet is cut off, forcing a sealing plate to separate from a baffle ring. A support spring stretches to push the solution to be extruded from the bottom of the barrel, and an electric push rod pushes two molds to close, and the extruded plastic is cut off through the cooperation of a sleeve and a cutter.
