Title:
BIODEGRADABLE COMPOSITE MATERIAL AND BIODEGRADABLE PLASTIC MOLDED ARTICLE
Document Type and Number:
Japanese Patent JP3886817
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a biodegradable composite material capable of exhibiting high mechanical strengths.
SOLUTION: Vegetable natural fibers treated with a surface-treating agent capable of reacting with the OH groups of cellulose is homogeneously compounded into a biodegradable plastic having an ester structure. Thereby, the interaction of the OH groups of the cellulose activated by the chemical reaction of the surface-treating agent with the ester groups of the biodegradable plastic improves the wettability of the fiber surfaces, and enhances the adhesiveness of the interfaces to sufficiently integrate both the materials. Therefore, the biodegradable composite material which gives molded articles having large mechanical strengths and has high practicality can be obtained.
