BAMBOO BUILDING CURTAIN WALL PLATE AND PREPARATION METHOD THEREOF

The present invention belongs to the field of building curtain walls, and provides a bamboo building curtain wall plate including a bamboo substrate; a metal connecting member which is disposed on the back surface of the bamboo substrate and is connectable to the main body of a building; and a weather-resistant outer-decorative coating layer which is disposed on the surface of the bamboo substrate. The bamboo substrate includes an outer layer which is a wood veneer or a bamboo material; and a core layer which is a bamboo material. The bamboo substrate has a thickness of 8-15 mm. In the present invention, bamboo is used as a main raw material for production, and the method for preparing the bamboo building curtain wall plate has easily-available materials and is easy to implement. The index of the bamboo building curtain wall plate of the present invention meets the provisions about the weather-resistance performance index of the curtain wall plate in the standard "JG/T260-2009 high-pressure laminates-sheets based on thermosetting resins for curtain wall", and has a strength performance which can meet the index requirements for a wood load-bearing enclosure sheet in a building structure. The present invention also provides a method for preparing the bamboo building curtain wall plate, which is simple in operation, low in energy consumption for production, and capable of expanded production.
