Molding material, molded part, and method for manufacturing them |
摘要 |
A method for manufacturing a molded part with an improved convenience and a high degree of efficiency in molding is provided, the molded part containing a biodegradable resin composite, which has the heat resistance in a wide temperature range and which is provided with the flexibility and the elongation in accordance with the use. A kneaded product of a biodegradable resin component and a cross-linkable monomer is prepared. The biodegradable resin component is cross-linked and ground to prepare a biodegradable resin cross-linking product powder. An impregnant at a temperature of 60° C. or higher, and lower than or equal to the melting point or degradation temperature of the biodegradable resin component is impregnated to prepare a molding material composed of a biodegradable resin composite powder. The molding material is heated to a temperature higher than or equal to the melting point of the biodegradable resin component to mold into pellets.
