THERMOPLASTIC RESIN MATERIAL, MOLDED ARTICLE, METHOD FOR MOLDING THE SAME, CONSTRUCTION MATERIAL, FILLING MEMBER USED FOR STORAGE OR PENETRATION FACILITY OF WATER AND METHOD FOR MOLDING THE SAME MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a thermoplastic resin material for which recycled polyolefin-based resin and recycled polystyrene-based resin having relatively large recycled amount in industries are suitably used, capable of exhibiting a good physical properties by not necessarily laminating virgin resins having the high physical properties, a molded article and method for molding the same, a construction material and a filling member used for the storage and penetration facility of water and a method for molding the same member.

SOLUTION: This thermoplastic resin component consisting of (A) 100 pts. wt. polyolefinic resin having 0.3-1.3 GPa tensile elastic modulus and 15-25 MPa tensile yield strength and (B) 25-1,000 pt. wt. polystyrenic resin having 1.8-3.2 GPa tensile elastic modulus and 15-45 MPa tensile yield strength is composed of an islands in sea structure obtained by setting (A) the polyolefinic resin as the islands and (B) the polystyrenic resin as the sea, or a both continuous structure of setting both of (A) the polyolefinic resin and (B)the polystyrenic resin as the sea.
