NATURAL VEGETABLE COMPOSITE MOLDING AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a natural vegetable composite molding comprising natural vegetable wastes, such as wood and cork, and an organic matrix and having water resistance, flexibility, heat resistance and durability, to provide a composite laminate molding obtained by laminating the molding on another thermoplastic elastomer molding, and to provide a method for producing the molding.;SOLUTION: The natural vegetable composite molding (A) is obtained by mixing ≥50 pts.wt. but ≤300 pts.wt. natural vegetable fragments in 100 pts.wt. first thermoplastic elastomer having an unsaturated group; The natural vegetable composite molding (B) is obtained by laminating the (A) on at least one side of a second thermoplastic elastomer molding layer; The method for producing the (B) comprises pressure forming of a mixture comprising the thermoplastic elastomer having unsaturated groups and natural vegetable fragments containing water at ≥100°C but ≤180°C, once decreasing pressure to release generated steam from the mixture, pressure forming again and cooling, taking out the molding at ≤80°C to produce the (A) and laminating the obtained on the second thermoplastic elastomer molding.;COPYRIGHT: (C)2007,JPO&INPIT
