Description
さらに本発明のプラスチック段ボールにおいて、配合されている前記デンプンは、このデンプンを成分として含有する植物を、その固有に含む水分又は適宜追加される水分と、前記樹脂主剤とともに加熱混練し、糊化してから分散させたものであることを特徴とする。
このように発明が構成されていることにより、加熱混練の最中に、植物に含まれるデンプンが水分と反応して糊化し、溶融している樹脂主剤に微細に混合されていくこととなる。これにより、一般的な樹脂成形法を適用して形成したプラ段は、樹脂主剤の母相中に、デンプンの分散相が分子鎖レベルで微細に均一に分散している組織が得られる。
これにより、使用済みのプラ段を土壌に埋立処理する場合であっても、微生物による分解速度が高速化されるので、同じ埋立処分場に繰り返して埋め立てる間隔を短縮化させることができる。
Further, in the plastic corrugated cardboard of the present invention, the compounded starch is a plant containing this starch as a component, heat-kneaded together with water inherently contained or appropriately added water and the resin main ingredient, and gelatinized. It is characterized by being dispersed from .
Thus constituted, the starch contained in the plant is gelatinized by reacting with moisture during heating and kneading and finely mixed with the molten resin main ingredient. Thereby, the plastic stage formed by applying a general resin molding method can obtain a structure in which the dispersed phase of starch is finely and uniformly dispersed at the molecular chain level in the matrix of the resin main component.
Thereby, even when the used plastic stage is landfilled in the soil, the decomposition rate by the microorganisms is increased, and therefore, the interval between repeated landfills in the same landfill disposal site can be shortened.
