Abstract
The invention provides a kind of preparation method of foam metal mandruka, including the pre- hot-stretch-sizing of sponge substrate-oxide-film removal.Preparation method of the invention, process is simple, the mandruka prepared using the inventive method, with more uniform hole body structure, effectively enhance the metal level uniformity of nickel foam, the electric conductivity and tensile strength of material are improve, foam nickel material is effectively improved for easily occurring fracture and the excessive problem of internal resistance in pole piece preparation process, the need for more meeting vehicle mounted dynamic battery.
Description
Technical field
The present invention relates to a kind of preparation method of porous metal material base material, more particularly to a kind of preparation method of foam metal mandruka.
Background technology
Nickel foam, with larger specific surface area, is widely used as anode plate material due to tridimensional network.Polyurethane cellular sponge be prepare nickel foam must matrix material, nickel foam prepared by conventional polyurethane cellular sponge, because the limitation of mandruka foam process in itself, hole shape is very uneven, and the rib size in composition hole is very uneven, cause rougher as the microcosmic crystal structure of material prepared by matrix material out using it, size differs, this material is when battery is made, chemical resistance is higher, the impact of larger current cannot be born, it is especially applicable to pure electric automobile field, easily cause the anode plate being fabricated to by nickel foam and fracture is produced in cell operations, so as to have influence on the service life of battery and use safety.
The content of the invention
The present invention is intended to provide it is a kind of make hole shape evenly, the preparation method of the finer and close vehicle mounted dynamic battery positive electrode substrate material foams nickel mandruka matrix material of structure.
The present invention is realized by following scheme：
The preparation method of foam metal mandruka, it is characterised in that comprise the following steps：
（1）The pre- hot-stretch of sponge substrate：By special stretcher, make mandruka in 80-100 DEG C of temperature, stretching pulling force is 0.1-0.5MPa, draw speed under the process conditions of 0.01-0.05m/min to carry out Uniform Tension；
（2）Remove oxide film dissolving：Stretched and after shaping mandruka base material is placed in NaOH 60-100g/L, sodium carbonate 30-60g/L, tertiary sodium phosphate 30-60g/L, 40-60 DEG C of temperature except surface oil stain removal is carried out in oil solution, process time is 5-10min；The mandruka that will be gone after oil processing again is placed in acetic acid 5ml/L, hydrochloric acid 5ml/L, and surface film oxide removal is carried out in the Acidwash solution of 30-50 DEG C of temperature, and process time is 5-10min.
The mandruka thickness is 0.8-5.0mm.
Compared with prior art, advantages of the present invention is embodied in：
1. the method for the present invention, process is simple, it is easy to accomplish large-scale production.
2. the mandruka for being prepared using the inventive method, with more uniform hole shape structure and rib structure, effectively enhance the compactness and intensity of nickel foam inside hole connection structure, improve the electric conductivity of material, foam nickel material is effectively improved for easily occurring fracture and the excessive problem of internal resistance in pole piece preparation process, the need for more meeting vehicle mounted dynamic battery.
