| titleOfInvention | Separation chemical mixture and mechanical method of urethane film from automotive instrument panel skin for TPO recycle |
| abstract | The present invention relates to a urethane film separator for recycling pure TPO from an automobile instrument panel skin coated with a urethane film on the surface of a TPO (thermoplastic olefin) material of an automobile instrument panel skin, and a separation method using the urethane film separator. More particularly, Using pure TPO material, it is possible to recycle pure TPO material into high value-added fields by completely separating the urethane film coated on the surface of TPO material from the defects of automobile instrument panel skin sheet coating process or scrap generated in the process without damaging the material. The present invention relates to a urethane film separator for regenerating a TPO material for an automotive instrument panel skin, which is capable of separating a urethane film in an environmentally friendly and efficient manner, and a separation method using the urethane film separator. According to the present invention, there is provided a method for producing an aqueous alkaline solution comprising: 10 to 40% by weight of an alkali aqueous solution of sodium hydroxide (Caustic Soda) or potassium hydroxide; 20 to 50% by weight of an alcohol mixture; 1 to 5% by weight of an ether-based solvent; 0.5 to 5.0% by weight of a nonionic surfactant; And 30 to 50% by weight of water; and a urethane film separator for regenerating a TPO material for an automotive instrument panel skin. A surface activation step (S100); Separating the urethane film by the separating agent (S110); A sludge solid-liquid separation step (S120); A recovered separated liquid reuse step (S130); Washing step S140; Drying step S150; And separating the urethane film separator for a TPO material for an automotive instrument panel skin. |
