Specifically, the method provided by the invention comprises the steps of shredding the foamed aluminum leftover materials into particles, and uniformly mixing the particles with glue to obtain a raw material mixture; and laying a layer of release film in the mold, laying the raw material mixture on the release film in the mold, covering a layer of release film, carrying out hot pressing treatment, and removing the release film to obtain the foamed aluminum laminated board.
According to the method provided by the invention, in order to ensure the indiscriminate utilization of the foamed aluminum leftover materials and overcome the defects of time and labor waste caused by the selective use and the selective use of the foamed aluminum leftover materials in the splicing mode adopted in the prior art, the foamed aluminum leftover materials are firstly crushed, and the foamed aluminum leftover materials are naturally polluted by oil stains in the processes of collection, transportation and storage for later use due to different sources of the foamed aluminum leftover materials.
According to the method provided by the present invention, the particle size of the particles obtained by shredding the foamed aluminum scrap can be selected within a wide range, but the inventors of the present invention found that the smaller the particle size after shredding is, the more uniform the finally produced foamed aluminum laminate can be ensured, but the smaller the particle size is, the more likely the pore structure of the foamed aluminum material is to be further destroyed, and preferably, in the present invention, the particle size of the particles obtained by shredding the foamed aluminum scrap is 5 to 8 mm.
According to the method provided by the invention, the glue is used for bonding granular foamed aluminum obtained by shredding leftover materials of the foamed aluminum together, and as a specific implementation mode of the glue, the glue is double-component glue, specifically epoxy AB glue, wherein the component A is an epoxy adhesive, the component B is an epoxy curing agent, and the using weight ratio of the component A to the component B is 1: 1.

According to the method provided by the invention, in order to further improve the bonding effect between the granular foamed aluminum and ensure that a uniform foamed aluminum laminated plate is obtained, the granular foamed aluminum mixed with the two-component glue is subjected to hot pressing treatment. The conditions of the hot pressing treatment can be selected in a wide range, and preferably, the conditions of the hot pressing treatment comprise that the temperature of a hot press is set to be 100-150 ℃, the pressure is 100KN, and the hot pressing heat preservation time is 15 min.
In order to further improve the strength of the prepared foamed aluminum laminated plate, the method also comprises the steps of carrying out instant bonding hot pressing on one side or two sides of the prepared foamed aluminum laminated plate by using a high-temperature heating roller; the specific conception is that the surface layer of the foamed aluminum laminated board is melted under the action of high-temperature heating, and the compact layer with a certain thickness is obtained by sacrificing the performance of part of the foamed aluminum material, so that the finally prepared and formed foamed aluminum laminated board is of a double-layer structure of the compact layer and the foamed aluminum layer, or a three-layer structure of the compact layer, the foamed aluminum layer and the compact layer.
In a further technical scheme, the heating temperature of the high-temperature heating roller is 780-820 ℃, and the condition of instant bonding and hot pressing can be determined according to the thickness of the 'compact layer' finally required; in addition, in order to meet the requirement of high-temperature heating, the glue is high-temperature resistant glue, and specifically, for example, HR-8812 copper oxide high-temperature glue which is available from Virginian glue industry Co. In the raw material mixture, the dosage of the high temperature resistant glue is 15-25% of the weight of the foamed aluminum leftover material.
The following will further describe the method for producing the foamed aluminum laminated sheet according to the present invention with reference to specific examples.
Example 1
A preparation method of a foamed aluminum laminated plate comprises the following specific steps:
(1) collecting foamed aluminum leftover materials, removing impurities, cleaning, drying, and then shredding by a shredder to form granular foamed aluminum materials with the grain size of 7 mm;
(2) mixing the granular foamed aluminum material in the step (1) with epoxy AB glue, and uniformly stirring to obtain a raw material mixture, wherein the amount of the epoxy AB glue is 26% of the weight of the foamed aluminum scrap;
the epoxy AB adhesive is a water-based resin product purchased from the Jinhong adhesive industry, the component A is an epoxy adhesive, the epoxy equivalent is 210g/mol, the component B is an epoxy curing agent, and the amine value reaches 180 mgKOH/g;
(3) laying a layer of release film at the bottom of a cavity of the mold, then laying the raw material mixture obtained in the step (2) on the release film, covering a layer of release film, raising the temperature to 120 ℃, setting the pressure to be 100KN, and carrying out hot-pressing and heat preservation for 15 min; and after the heat preservation is finished, naturally cooling to room temperature, removing the pressure, and removing the release film to obtain the foamed aluminum laminated board.
Comparative example 1
This embodiment is substantially the same as the method for producing an aluminum foam laminated board in example 1, except that in step (1), the shredder is controlled to shred the aluminum foam scraps to obtain granular aluminum foam having a particle size of 12 mm.
Example 2
A preparation method of a foamed aluminum laminated plate comprises the following specific steps:
(1) collecting foamed aluminum leftover materials, removing impurities, cleaning, drying, and then shredding by a shredder to form granular foamed aluminum materials with the grain size of 6 mm;
(2) mixing the granular foamed aluminum material obtained in the step (1) with high-temperature resistant glue (HR-8812 copper oxide high-temperature glue obtained from Virginia glue Co., Ltd.) and stirring uniformly to obtain a raw material mixture, wherein the dosage of the high-temperature resistant glue is 20% of the weight of foamed aluminum scrap;
(3) laying a layer of release film at the bottom of a cavity of the mold, then spreading the raw material mixture obtained in the step (2) on the release film, covering a layer of release film, raising the temperature to 140 ℃, setting the pressure to be 100KN, and carrying out hot-pressing and heat preservation for 15 min; and after the heat preservation is finished, naturally cooling to room temperature, removing the pressure, and removing the release film to obtain the foamed aluminum laminated board.
Example 3
On the basis of the foamed aluminum laminated board prepared in example 2, instantaneous bonding hot pressing was performed on both sides of the foamed aluminum laminated board prepared using a heating roller at a temperature of 800 ℃, the pressure of the heating roller rolling on the surface of the foamed aluminum laminated board was 30MPa, and the roller speed was 10 m/min.
In order to unify experimental conditions and avoid the influence of foamed aluminum leftover materials of different specifications and models on the experiment, the foamed aluminum leftover materials with the density of 0.5g/cm3 are adopted as the foamed aluminum leftover materials (the compressive strength is 44MPa, the bending strength is 27MPa, and the noise reduction coefficient is 0.78; wherein, the mechanical test standard refers to GB/T1038-1040, and the sound insulation and noise reduction performance refers to GBT47 and GBJ88), the schemes of examples 1-3 and comparative example 1 are implemented, and the mechanical properties of the prepared foamed aluminum laminated plate are tested, and the specific test data are shown in Table 1:
table 1:
based on the test data, the foamed aluminum laminated plate prepared by the method provided by the invention not only fully utilizes the foamed aluminum leftover materials, but also greatly maintains the excellent properties of the foamed aluminum material, particularly the sound insulation and noise reduction properties, and has better application prospect in some scenes with lower requirements on mechanical properties although the mechanical properties are obviously reduced. In specific experimental comparison, as in comparative example 1, the tearing degree of the foamed aluminum scrap is weak (the particle size is 12mm), the noise reduction capability of the foamed aluminum scrap is better maintained, but the mechanical property data of the foamed aluminum laminated plate made of the granular foamed aluminum material is poor, and the tearing degree has an influence on the performance of the foamed aluminum laminated plate; the data comparison of the examples 2 and 3 shows that the mechanical property can be remarkably improved by further processing the foamed aluminum laminated plate based on the method provided by the invention, but the noise reduction performance is deteriorated.
The foregoing shows and describes the general principles, essential features, and inventive features of this invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
