The device has simple structure, convenient operation and safe use, and the method for preparing the foamed aluminum roll blanket by using the production device fundamentally solves the problems of producing the through hole foamed aluminum with stable structure, small and uniform large-area aperture and high porosity.
Description
Technical field
Patent of the present invention relates to a kind of technology of producing foamed aluminium, and particularly a kind of production aperture is tiny, even, porosity is high, the production equipment of large-area through-hole foam aluminium roll blanket and utilize this production equipment to prepare the method for foamed aluminium roll blanket.
Background technology
Foamed aluminium is the most common in the porous foam metal, that application prospect is best a kind of material, and it is that a kind of physical property of metallic surface of utilizing produces the structure function material of special role.Because it has special structure, so its Application Areas relates to material structure and physical some key areas.The application of configuration aspects is mainly in multiple industry such as automobile, space flight, building; Function is used and to be comprised: flow in damping in-fighting, acoustics, hot physics, the porous medium, electromagnetism etc.
Porous foam metal material has the history of five more than ten years, does the whipping agent foaming because of its original adoption mercury, and this foaming technology controlling and process is very difficult, so the development work of porous foam metal has stopped recent two decades.Up to finding new whipping agent, the development of porous foam metal just enters a new stage.Along with people recognize this gradually is a kind of crucial high-tech novel material, and very application prospects is arranged, and porous foam metal material has become the material of trying to be the first and develop in countries in the world.Japan, the U.S., West Europe are dropped into substantial contribution year after year and are studied this project, and on the preparation method, obtaining some impressive progress aspect the simulation of the important parameter of preparation process, on some patent documentations, disclose the technology contents of many this respects, made porous foam metal material in the nearly more than ten years, considerable progress arranged.The continuing to bring out of new preparation method, control techniques are gradually improved.
The main preparation methods of existing porous foam metal material can be divided into three major types:
One, foaming preparation technology (liquid, solid-state); Two, seepage flow casting preparation technology; Three, electrodeposition technology.
The first kind: liquid metal foaming preparation technology is: after the aluminum or aluminum alloy fusing, insulation is at a certain temperature stirred, and adds tackifier, adds whipping agent again, perhaps solidifies in crucible, perhaps is poured in the model and solidifies, and can obtain foamed aluminium; Solid-state foaming can be described as powder metallurgic method again.Pure aluminium powder or Al alloy powder together, be compacted into blank, be placed in the controlled atmosphere generator,, just can produce foamed aluminium by certain technology sintering with the whipping agent uniform mixing of certain proportion.Just know from above-mentioned production technique, the pore size of the foamed aluminium of Sheng Chaning in this way, degree of uniformity and porosity all have very big uncertainty.Therefore, scrap rate is higher.The foamed aluminium that this method is produced, the hole is not communicated with mutually, is called as closed-cell aluminum foam.
Second class: the technology that the seepage flow casting prepares foamed aluminium is to be deposited in together with controlled-size solid particle (as dissolved salt, glass, pottery etc.), then, molten aluminum liquid is poured in the slit of solid particulate, again solid particulate is removed after the condensation, just obtained foamed aluminium.The hole of the foamed aluminium that this method is produced is interconnected, and is called fine-crystal spume aluminium alloy.The homogeneity in its aperture can be accomplished, but its porosity is lower.
The 3rd class: electrodeposition technology can be described as electroplating technology again.Can be divided into wet electrochemical plating and dried electrochemical plating.Electroplating in water-soluble electroplate liquid is the main technique method of production nickel foam.In water-insoluble electroplate liquid, electroplate and can be used to produce foamed aluminium.And do electrochemical plating is that electroless plating liquid is electroplated, or claims physical vaporous deposition.
The constitutional features of the foamed aluminium of two kinds of explained hereafter of first and second class is as follows: aperture ratio is φ 0.3～8mm more greatly, and inhomogeneous, and voidage is 60～90%, specific surface area 1000～4500m
2/ m
3In the actual production, structure control is difficulty, and scrap rate is higher, and therefore, cost is higher.Because the performance of foamed aluminium depends primarily on its structure, therefore, the various performances of the foamed aluminium of producing with these two kinds of methods have been difficult to raising more.How the pore structure of control foam aluminium makes it more stable, more tiny, more even, and the rate of reducing the number of rejects and seconds is the target that production firm is pursued always.
Wet electroplating technology is the main technique method of current production nickel foam.The pore structure of the foamed metal of electrodip process production depends primarily on selected base material.What the structure that is to say selected porous plastics is, what sample is the structure of foamed metal be exactly.This has just fundamentally solved the structural stability problem of foamed metal.Stability Analysis of Structures, the stability problem of performance just has been readily solved.Because its structure depends on the structure of porous plastics, therefore, scrap rate is low, and cost is lower.Yet water-soluble electroplate liquid is electroplated and can only be used for metals such as nickel plating, iron, copper, cobalt, chromium.Electrodip process is produced foamed metal, once reports in some foreign patents, as mentioning the production nickel foam in EP-B1-0151064, the US5503941 patent; Relate in the DE10123585 patent and produce inflatable metal and foamed metal, but be metals such as copper, nickel, cobalt, iron, do not comprise aluminium; Relate in the EP921210 patent with covering and agglomerating method production nickel porous-Al alloy composite, wherein, nickel dam is to adopt electro-deposition method, and aluminium lamination then is to adopt the organic compound thermal decomposition method sedimentary.
The inventor once structure control at above-mentioned foaming or the existence of seepage flow casting is difficult, the scrap rate problem of higher, a kind of employing electrodip process is proposed, with water-insoluble plating bath---anhydrous Organoalkyl aluminium electrolyte is produced the method for foamed aluminium, fundamentally solve the structural stability problem of foamed aluminium, prepared the fine-crystal spume aluminium alloy that the aperture is tiny, even, porosity is high.But, because of organic plating bath all is inflammable, so it is the hidden danger of the maximum of safety in production.In addition, organic plating bath also can not be ignored the pollution problem of environment.Therefore, this preparation method needs further to improve.
Summary of the invention
The purpose of this invention is to provide production equipment of a kind of foamed aluminium roll blanket and preparation method thereof, this apparatus structure is simple, easy to operate, safe in utilization, it has fundamentally solved production structure fine-crystal spume aluminium alloy problem stable, that large-area aperture is tiny, even, porosity is high, compare with wet electrochemical plating, has the quality product of significantly improving, the rate of obviously reducing the number of rejects and seconds is guaranteed production safety, the advantage of environmentally safe.
