熱可塑性樹脂含有回収材からの添加材含有熱可塑性樹脂部品成形材料の製造方法

Japanese Patent JP5468317

B2

PROBLEM TO BE SOLVED: To provide a manufacturing method of molding materials for thermoplastic resin parts that can be advantageously used for molding the resin parts having specific properties using recovered thermoplastic-resin-containing crushed materials as the primary raw material.SOLUTION: The manufacturing method includes the following steps: determination of property items necessary for the resin parts of a molding object; determination of a target property value for each item; preparation of data showing a correlation between variation of contents of thermoplastic resin components and additive components and variation of property values, or acquisition of the data prepared in advance; acquisition of recovered crushed materials; analysis of component compositions of the crushed materials; preparation of a molded sample from the crushed materials; measurement of the properties of the molded sample; extraction of items of insufficient property by comparing the measured properties and the target properties; calculation of an estimated amount of the thermoplastic resin components and/or additive components to be added that is required for attaining the target property from an insufficient property value, a component analysis value of the crushed materials and the correlation data.
