A kind of production process of aluminum foam composite plate and plate

Abstract

The invention discloses a foamed aluminum composite sheet material production process and the sheet material. The foamed aluminum composite sheet material comprises a formed aluminum plate and face plates arranged on two sides of the foamed aluminum plate; the face plates are bonded with the formed aluminum plate through adhesive films; the face plates on the two sides are respectively taken as afirst face plate and a second face plate; a first adhesive film is arranged between one side of the formed aluminum plate and the first face plate; and a second adhesive film is arranged between the other side of the formed aluminum plate and the second face plate. The face plates on the two sides of the formed aluminum composite sheet material provided by the invention are bonded with the formedaluminum plate through the adhesive films, and the traditional bonding mode of liquid glue is replaced, so that glue is prevented from entering into pores of the foamed aluminum, and the composite sheet material is lighter in weight; the stress distributed at each point between the adhesive films and the bonding surfaces of the face plates is uniform, so that the bonding strength among the layersof the composite sheet material is improved.

Description

technical field [0001] The invention relates to the field of composite boards, in particular to a production process of foamed aluminum composite boards and the boards. Background technique [0002] Wooden boards are traditional home decoration materials, mainly processed into floors, furniture, doors, etc. Wooden boards are weak in hardness, easy to be damaged by collisions, and deformed. In order to improve the strength of the material, metal plates are used instead of wood on some furniture, but metal plates are heavy and inconvenient to transport and install. In the prior art, wood boards and metal plates are also used to make composite boards. This composite board has high strength, but still has the problems of high density and inconvenient construction. Moreover, the flame-retardant and heat-insulating properties of the wood board and the metal board are insufficient. When encountering an open flame, the wood board cannot be flame-retardant and is likely to cause a f...

Problems solved by technology

For example, the invention patent with the patent number CN201610195205.9 provides a new type of wood board composite aluminum foam material. In the disclosed technical scheme, the wood boards are bonded by adhesive on both sides of the foam aluminum board. This processing method is complicated to operate and the production The efficiency is low, which will cause environmental pollution. When bonding, the glue will enter the gaps in the foamed aluminum, resulting in an increase in the density of the composite board.

Moreover, the glue has fluidity, so that the adhesive content of each point on the bonding surface is different, and the bonding force of each point on the bonding surface has a large difference, which affects the overall bonding strength of the composite material.
