Abstract

The invention discloses a composite board, comprising a composite layer, an upper adhesive layer and a lower adhesive layer respectively bonded with the upper and lower surfaces of the composite layerto form an integral body with the composite layer, and a functional surface layer bonded with the upper surface of the upper adhesive layer to form an integral body with the upper adhesive layer. According to the invention, the upper adhesive layer and the lower adhesive layer respectively cover the upper and lower surfaces of the composite layer, and the functional surface layer is laminated with the upper surface of the upper adhesive layer via a film spraying method, so the prepared composite board has excellent impact resistance and the advantages of high mechanical strength, ageing resistance, scratch resistance, etc.; meanwhile, the functional surface layer endows the composite board with unique appearance and functionality; moreover, since one part of the upper adhesive layer is embedded into the upper surface of the composite layer and another part of the upper adhesive layer is embedded into the lower surface of the functional surface layer, such mechanical bonding can improve peeling strength between the functional surface layer and the composite layer; and the lower adhesive layer may be embedded into the lower surface of the composite layer so as to realize bonding between the composite board and other materials.

Description

technical field [0001] The invention relates to the field of composite material panels, in particular to a composite material panel and a preparation method thereof. Background technique [0002] At present, special transportation facilities such as refrigerated containers, refrigerated trucks, trucks, and RVs generally use steel plates or thermosetting composite material plates as inner linings or wall panels. Repair, high thermal conductivity, poor heat insulation effect. The thermosetting plastic composite lining board has high gloss and smooth appearance, but it has poor impact resistance, is easy to crack and scratch, and has poor cleaning performance. At the same time, food processing factories, breweries, pharmaceutical factories and other processing plants, school cafeterias, hospitals, hotels and other public places are required to have antibacterial and mildew-proof, waterproof and moisture-proof, and easy-to-clean functions, while ordinary walls are prone to foam...
