The thermoplastics material, production mannered null recycling polystyrene type resin 60 of the engineering works

摘要

PROBLEM TO BE SOLVED: To provide a thermoplastic resin molded article which exhibits good physical properties without necessarily laminated with a resin having high physical properties, such as a virgin resin, and having good chemical resistance and oil resistance which are favorable to a civil engineering material, in particular; to provide a civil engineering material using the same; and to provide a production method for a recycled thermoplastic resin molded article.;SOLUTION: The thermoplastic resin molded article comprises a polystyrenic resin, a polyolefinic resin having 0.3-1.3 GPa tensile modulus and 15-25 MPa tensile yield strength, and preferably comprising 5-60 pts.wt. inorganic filler based on 100 pts.wt. resin components. Wherein the existing structure of the resin components at the surface of the molded article is specific in that, the spectrum ratio of an absorption wavelength of a benzene ring in the polystyrenic resin (1,493 cm-1) to an absorption wavelength of a methylene portion in the polyolefinic resin (1,463 cm-1), which is obtained by an ATR method, is 0-1.2.;COPYRIGHT: (C)2005,JPO&NCIPI
