Abstract

This invention is a kind of regenerative environmental protecting type solid core wooden door and window. It is combined with frame structural section, sector structural section, middle frame structural section and sealing strips. The structural sections are solid core structural section. Their side faces are coated with plastic layer. The indoor face and outdoor face are coated with aluminum-coated layer through glue line. The main raw materials of the said solid core structural sections are regenerative polyolefine resin, plant fiber filler and auxiliary agent. The said regenerative polyolefine resin is the mixture of regenerative polypropylene and regenerative polyethylene. The plant fiber filler is wood fiber powder, hemp fiber powder, bamboo fiber powder, grass fiber powder, chaff powder or straw fiber powder. This invention decreases environmental pollution. It will not generate harmful gas when being heated. It also increases the anti-ultraviolet radiation, aging resistance and heat insulating performances.
