ABSTRACT:
Rubber waste fine particles in the form of fine particles obtained by crushing rubber waste and plastics waste rugged rough particles formed by crushing molded polyethylene or polypropylene waste are mixed to obtain a raw material mixture. When the mixture is heated, only the plastics waste rugged rough particles are melted, and the resulting material is pressed and injected to mold it into the desired shape. The thus obtained composite material exhibits an ebony-like configuration, and is light in weight, high in hardness, excellent in toughness, and rich in water resistance and weather resistance.
