Description
Technical field
The present invention relates to a kind of foam materials and preparation method thereof, particularly relate to a kind of nickel foam and preparation method thereof.
Background technology
Porous foam metal, alloy are a kind of Multifunction materials, there is three-dimensional net structure, porosity is high, specific surface area is large, physical strength is high and the excellent feature of antioxidant property, be the desirable equivalent material of fragility porous ceramics, have broad application prospects in fields such as various high-temperature catalytic carriers, anti-corrosion catalyst carrier, strainer and heat exchangers.
Nickel foam is one important in foamed metal, and it has good saturating fluid property, sound absorption qualities etc., can be used as the electric wave shielding material of loud speaker carton, the pulse power etc. in metallic filter, stereo set etc.According to recent nickel magazine report, the foamed metal that the grid that is 0.05～1.0mm by skeleton thickness is made, has the function different from traditional sintered porous metal and characteristic, and uses in the Application Areas that can cannot relate in conventional metals.For example, porosity can reach 98%, in hole, can fill other material, and specific surface area is large, and gas-permeable resistance is little, and slab product can cut or suppress.
Be published in 2011 in " non-ferrous metal scientific and engineering " document of the 2nd the 3rd phase of volume " research of Electrodeposition for Manufacturing Foamed Nickel ", the Liu Baixiong of engineering research institute of Institutes Of Technology Of Jiangxi, clock element literary grace prepare with the operational path of " high chrome liquor alligatoring → chlorination pink salt sensitization → Presence of Silver Nitrate Activator → formaldehyde reduction → electroless copper → high temperature sintering " that voidage is high, through-hole foam nickel, study the impact of each technique on preparation, to preparation nickel foam is produced to stronger directive significance.
The Sumitomo electrical equipment industry company limited of Japan Itami has developed a kind of nickel foam metal of uniqueness, and its maximum pore rate can reach 98%, and can be bending, cut and be pressed into multiple net shape part, this material is called micropore metal.The said firm is with heat-treating with the urethane electrolytic deposition nickel of electrically conductive graphite coating, and the method for polyurethane and graphite of removing from foam is produced nickel foam material, and corrosion resistant nickel and nichrome are particularly suitable for this technique.
At present, foamed alloy kind is also little, and preparation method is more single, is mainly solid phase powder entrapping method, gas alloying.There is unsatisfactory part in these processing methodes, in solid phase powder embedding preparation process, powder is easy to the skeleton surface of sintering at foamed alloy, has reduced the use properties as strainer; Gas alloying complex process, cost is high.Also can prepare foamed alloy with electrodip process, this method technique is simple, easy and simple to handle, and cost is lower.
Summary of the invention
The present invention aims to provide a kind of nickel foam, it is characterized in that being made up of the carbon foam substrate of conducting electricity and substrate surface nickel coating.Material internal presents tridimensional network, by forming staggered connection of irregular holes not of uniform size, has large specific surface area, can fill phase transformation, inhale the multiple materials such as ripple.This nickel foam material is taking carbon foam as substrate; utilize the surface tissue of the complete succession carbon of plated metal nickel dam foam; nickel coating had both effectively been protected carbon material; form in appearance again a kind of new nickel foam; fully combining the excellent specific property of metallic substance and carbon material, is a kind of high-performance perforated foams with broad development prospect.
Carbon foam substrate of the present invention is to heat carbonization by polyurethane foam to obtain, and concrete technological process is carried out in two steps: first in air, polyurethane foam is heated at 200～255 DEG C; Then in inert atmosphere, carbonization at 700～900 DEG C; Thereby prepare carbon foam.These carbon foams have open-celled structure, and the long-width ratio in hole is 0.6～1.4, and density and compressive strength are respectively 0.085～0.387g/cm
3with 0.9～14.1MPa.
Carbon foam surface nickel coating is prepared by electric plating method: taking the carbon foam that makes as negative electrode and substrate, 99.99% pure nickel target is anode, and single nickel salt is main salt, by alternating-current pulse, at the nickel coating of carbon foam surface deposition 0.5～5 μ m.
The invention provides a kind of preparation method of nickel foam, it is characterized in that comprising the step of following order:
(1) heating, carbonization polyurethane foam are prepared carbon foam;
(2) the carbon foam making is cleaned up, in plating solution, fully flood 10～30min;
(3) taking carbon foam as negative electrode, pure nickel target is anode, connects alternating-current pulse, nickel deposited coating in carbon foam substrate, and controlling thickness of coating is 0.5～5 μ m, obtains nickel foam material.
Major advantage of the present invention is: the nickel foam material 1. making has the excellent properties of carbon material and metallic nickel concurrently, and inside presents the foamy structure of porous, has advantages of that quality is light, specific surface area is large; 2. in foam, can fill several functions material, effectively improve speed of reaction and effect, as filled PCM phase change material, enter foam when height is warm by top layer, foam is because of large specific surface area, and the PCM filling wherein can absorb heat fast; 3. adopt the preparation method who electroplates, technique is simple, easy and simple to handle, with low cost.
