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.

Embodiment 1

[0038] Such as figure 1 and figure 2 As shown, this embodiment provides a flame-retardant and heat-insulating aluminum foam composite board, including a foamed aluminum board 3 and panels arranged on both sides of the foamed aluminum board 3, and the two side panels are a first panel 1 and a second panel 5 respectively. The panel layer is made of wood or aluminum, copper, steel and other metal plates. Aluminum foam is a kind of porous metal with low density, high strength and low thermal conductivity, which makes this composite board have good sound insulation effect and flame retardant and heat insulation performance. The overall thickness of the aluminum foam composite board is between 12mm and 50mm, which can be applied to building and home decoration materials, which solves the shortcomings of a single board, can greatly improve the safety and comfort of the home environment, and has good application value and promotion prospect.

Embodiment 2

[0041] In this embodiment, on the basis of the above-mentioned embodiments, the adhesive used in the adhesive film is a curable adhesive resin, and the raw material formula of the curable adhesive resin includes the following components by weight percentage: 35% to 45% polyethylene, 35%-45% polyethylene graft polymer, 15-25% elastomer. Wherein, polyethylene is one or any combination of low-density polyethylene, linear low-density polyethylene, and high-density polyethylene. The polyethylene graft polymer is one or any combination of maleic anhydride grafted polyethylene and acrylic acid grafted polyethylene. The elastomer is one or any combination of SIS, SEBS, SBR, TPU, NBR. The density of the film is 0.92g / cm 3 -0.95g / cm 3 , less than the density of commonly used two-component epoxy resin glue 1.2g / cm 3 -1.4g / cm 3 , the resulting composite board is lighter.

[0042] There are physical stress and chemical stress between the adhesive film and the bonding surface. The physi...

Embodiment 3

[0044] In this embodiment, on the basis of the above-mentioned embodiments, the adhesive film includes a foamed aluminum adhesive layer and a board adhesive layer, which are respectively used for laminating the foamed aluminum plate 3 and the panel. In order to meet the overall thickness requirement of the composite board, the thickness of the foamed aluminum board 3 is between 10 mm and 30 mm, and the thickness of the panel is between 1 mm and 10 mm. The thickness of the aluminum foam adhesive layer is between 0.15mm and 0.25mm, and the thickness of the plate adhesive layer is between 0.1mm and 0.15mm. The thickness of the aluminum foam adhesive layer and the panel adhesive layer are different, which can meet the different bonding requirements on both sides. , wherein the contact area between the foamed aluminum adhesive layer and the foamed aluminum plate 3 is smaller than the contact area between the plate adhesive layer and the panel, so the thickness of the foamed aluminum...

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...
