Outline of Final Research Achievements

Activation of flow ability of wood powder by “mix of natural binder” and “press in steam” was proposed for producing wood-based material without petroleum-based plastics, which has high moldability and properties. Effectiveness of the proposed methods was verified. Fluidity of wood powder was activated by mixing the natural binder which is composed of sucrose and citric acid, and products were obtained successfully by injection molding. Strength and water resistance of the injection-molded product were the same level as conventional wood plastics by optimizing preparation of the binder. In addition, it was possible to steam-treat wood powder under very high pressure by using new device which was developed in this study.

Academic Significance and Societal Importance of the Research Achievements

石油系ではなく,スクロースやクエン酸といった天然系の添加剤を用いることによって,木質系材料の熱流動性・成形性が大幅に向上することは,これまでに報告されておらず,学術的に非常に意義のある成果である.また,本手法にて得られた製品は,一般的な木質プラスチックに匹敵する強度・耐水性を有する一方,焼却の際に有害な物質が発生することはない.これは,持続的発展が可能な循環型社会の構築に貢献する成果である.
