SYNTHETIC RESIN WINDOW FRAME
To provide, without excessively increasing production costs, a synthetic resin hollow window frame whose deformation is avoided as much as possible even in the case of being exposed to extreme temperature variations, whose heat-resisting property is remarkably improved, and whose strength is sufficient.SOLUTION: At least part of a synthetic resin hollow window frame is formed using a composition having vinyl chloride resin and chemically modified cellulose nanofibers as main components. Suitably, an internal layer is formed using a composition having recycled vinyl chloride resin and chemically modified cellulose nanofibers as main components and at least part of an external layer is formed using a composition having unused vinyl chloride resin as a main component.SELECTED DRAWING: Figure 1
【課題】製作コストを過剰に増大せしめることなく、過激な温度変化に晒されても変形が可及的に回避され、耐熱性が格段に向上され、充分な強度を有する合成樹脂製中空窓枠を提供する。【解決手段】合成樹脂製中空窓枠の少なくとも一部を塩化ビニル系樹脂及び化学修飾セルロースナノファイバーを主成分とする組成物から形成されている。好適には、内層はリサイクル塩化ビニル系樹脂及び化学修飾セルロースナノファイバーを主成分とする組成物から形成され、外層の少なくとも一部は未使用塩化ビニル系樹脂を主成分とする組成物から形成されている。【選択図】図１
