Embodiment 1

[0032] The present invention proposes a kind of preparation method of aluminum foam composite board, comprises the steps:

[0033] S1: Select a metal plate with the same size as the foamed aluminum plate according to the size of the foamed aluminum plate, reduce the cutting process after rolling, and carry out surface treatment on the metal plate to avoid the bond on the surface from affecting the bonding between the metal plate and the foamed aluminum plate , surface treatment steps:

[0034] (1) Grinding the surface of the metal plate with grinding paper to remove the adhesive on the surface of the metal plate;

[0035] (2) Put the metal plate into a container containing sodium hydroxide solution. The sodium hydroxide solution reacts with the impurities on the surface of the metal plate to remove the surface impurities. The sodium hydroxide solution immerses the metal plate and soaks the metal plate for 3 minutes. Control the temperature in the container to be 16°C;

Embodiment 2

[0057] The present invention proposes a kind of preparation method of aluminum foam composite board, comprises the steps:

[0058] S1: Select a metal plate with the same size as the foamed aluminum plate according to the size of the foamed aluminum plate, reduce the cutting process after rolling, and perform surface treatment on the metal plate to avoid surface adhesives affecting the adhesion between the metal plate and the foamed aluminum plate , surface treatment steps:

[0059] (1) Grinding the surface of the metal plate with grinding paper to remove the adhesive on the surface of the metal plate;

[0060] (2) Put the metal plate into a container containing sodium hydroxide solution. The sodium hydroxide solution reacts with the impurities on the surface of the metal plate to remove the surface impurities. Immerse the metal plate in the sodium hydroxide solution and soak the metal plate for 4 minutes. Control the temperature in the container to be 17°C;

Embodiment 3

[0082] The present invention proposes a kind of preparation method of aluminum foam composite board, comprises the steps:

[0083] S1: Select a metal plate with the same size as the foamed aluminum plate according to the size of the foamed aluminum plate, reduce the cutting process after rolling, and carry out surface treatment on the metal plate to avoid the bond on the surface from affecting the bonding between the metal plate and the foamed aluminum plate , surface treatment steps:

[0084] (1) Grinding the surface of the metal plate with grinding paper to remove the adhesive on the surface of the metal plate;

[0085] (2) Put the metal plate into a container containing sodium hydroxide solution. The sodium hydroxide solution reacts with the impurities on the surface of the metal plate to remove the surface impurities. The sodium hydroxide solution immerses the metal plate and soaks the metal plate for 5 minutes. Control the temperature in the container to be 18°C;

Abstract

The invention discloses a preparation method of a foamed aluminum composite plate, which comprises the following steps: S1, selecting a metal plate with the same size as a foamed aluminum plate according to the size of the foamed aluminum plate, and carrying out surface treatment on the metal plate; S2, putting the foamed aluminum plate into a heating device, controlling the heating temperature to enable the foamed aluminum plate to be heated to be softened, wherein the heating time is 4-8 min, and the foamed aluminum plate is taken out after being softened; S3, placing the metal plate on a foamed aluminum plate, and pressing the foamed aluminum plate on the metal plate through rolling; and S4, after rolling is finished, starting an air cooler, reducing the temperature of the foamed aluminum composite plate, and cooling the foamed aluminum composite plate to the normal temperature. According to the invention, the surface of the metal plate is polished through the polishing paper, sticking substances on the surface of the metal plate are removed, the metal plate is immersed in the sodium hydroxide solution, the sodium hydroxide solution reacts with impurities on the surface of the metal plate, the impurities on the surface are removed, and the connecting strength between the metal plate and the foamed aluminum plate is improved.

Description

technical field [0001] The invention relates to the technical field of foam rate composite boards, in particular to a preparation method of foamed aluminum composite boards. Background technique [0002] Aluminum foam is made by adding additives to pure aluminum or aluminum alloy and undergoing a foaming process, which has both metal and bubble characteristics. It has low density, high impact absorption ability, high temperature resistance, strong fire resistance, corrosion resistance, sound insulation and noise reduction, low thermal conductivity, high electromagnetic shielding, strong weather resistance, filtering ability, easy processing, easy installation, and high forming accuracy , Surface coating can be carried out, but the hardness of the aluminum foam board is small, and it needs to be compounded with the metal plate to improve the influence. In the existing aluminum foam composite board, the connection strength between the foam aluminum board and the metal board is...
