<p>PURPOSE:To provide a material generating method capable of regenerating sufficiently strong material without necessitating peeling work of paint film. CONSTITUTION:Member of polypropylene coated with urethane coating is crushed. A large number of crushed pieces 3 and water-soluble polymer 13 containing at least ethylene vinyl alcohol are put in a water tank 11 containing water 12 and stirred. The water is removed from this mixed liquid. By removing the water, solid new material having coat of the water-soluble polymer 13 formed on the surface of the crushed pieces 3 can be obtained.</p> |
