Title:
A PLASTIC COMPOSITE BOARD WITH FRICTION WELDED STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2007/137497
Kind Code:
A1
Abstract:
A plastic composite board with friction welded structure comprises a plastic surface plate (11) and an injection molded piece (12). The plastic surface plate (11) is extruded directly or vacuum-molded after extrusion. The injection molded piece (12) can be formed by injection molding directly or consisted of plural injection molded pieces. The plastic surface plate (11) and the injection molded piece (12) are welded together at the contact position by friction welding. Small protuberant points or stripes are arranged at the contact position between the injection molded piece (12) and the bottom surface of plastic surface plate (11), and can be melted to bind the plastic surface plate (11) and the injection molded piece (12) when friction welding. In the case that the higher structural strength is required, an internally embedded reinforcement can be placed between the injection molded piece (12) and the plastic surface plate (11) to enhance strength and decrease the amount of the injection molded piece (12) used. The plastic composite board can be applied to chair board, file cabinet, store cabinet, materiel shelf, wall decorative board, clothespress separator or the like.
