Title:
SYNTHETIC RESIN WINDOW FRAME
Document Type and Number:
Japanese Patent JP2020079531
Kind Code:
A
Abstract:
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
