METHOD FOR PRODUCING CELLULOSE ACETATE COMPOSITION AND ITS PRODUCTION SYSTEM

To provide a method for producing a cellulose acetate composition having sufficient functions as a biodegradable plastic which substitutes applications performed by a general-purpose plastic.SOLUTION: There is provided a production system 10 which comprises a first mixing vessel 11 for mixing a liquid plasticizer 26 while stirring a granular material of a cellulose acetate 25 to produce a first mixture 21, a second mixing vessel 12 for mixing the first mixture 21 and a filler 27 to produce a second mixture 22 and a kneader 30 for kneading the second mixture 22 by setting to a temperature at which viscous flow occurs.SELECTED DRAWING: Figure 1 【課題】汎用プラスチックが担ってきた用途を代替する生分解性プラスチックとして十分な機能を持つ酢酸セルロース組成物の製造方法を提供する。【解決手段】製造システム１０において、酢酸セルロース２５の粒状体を撹拌しながら液状の可塑剤２６を混合し第１混合物２１を生成する第１混合容器１１と、この第１混合物２１と充填剤２７とを混合して第２混合物２２を生成する第２混合容器１２と、第２混合物２２を粘性流動する温度に設定し混練する混練機３０と、を備える。【選択図】図１
