Background
Alkaline zinc-manganese dioxide batteries are developed on the basis of carbon zinc-manganese dioxide batteries in the middle of 20 th century, and are now an important portable power source in life and social production of people. The steel shell is used as a packaging container and a positive electrode current collector of the alkaline zinc-manganese battery, and has great influence on the electrochemical performance, storage and operation stability of the battery. In the production process of the steel shell, the nickel-plated steel strip is subjected to stretching and stamping forming through specific machinery, and dirt such as stretching liquid (oil-water mixture) is often remained on the surface of the formed steel shell, so that the surface is required to be cleaned, and then the treatment processes such as rust protection, graphite spraying and the like are performed, so that the corrosion resistance and the electronic conductivity of the steel shell are improved.
The early steel shell cleaning agent mainly comprises alkaline inorganic salts such as sodium carbonate, sodium silicate and the like, and has low price. However, the components of the cleaning agent are single, the cleaning capability is low, and the cleaning agent has a large limitation. The current commercial steel shell cleaning agent mainly comprises an anionic surfactant and a nonionic surfactant, various cleaning aids (including phosphate builder, corrosion inhibitor, defoamer, bactericide and the like) are combined, the price is relatively high, and the waste liquid of the phosphorus-containing cleaning agent can cause eutrophication of aquatic plants and pollute the environment. In addition, even if the surface of the steel shell cleaned by the commercial steel shell cleaning agent is subjected to sealing treatment, the rust-proof effect is still not ideal; meanwhile, the dyne value (the measurement of the estimated surface tension) of the surface of the steel shell after cleaning is low, which is unfavorable for the subsequent graphite spraying. Therefore, how to construct a low-cost and effective cleaning agent system, which can remove residual dirt on the surface of the steel shell and improve the corrosion resistance and the surface tension of the steel shell, is still needed to be further explored and developed.

In addition, after the nickel-plated steel shell is cleaned by the cleaning agent, the dyne value of the inner surface of the nickel-plated steel shell is also improved to a certain extent, and the adhesion of graphite sprayed on the inner surface of the subsequent steel shell is facilitated. Compared with the commercial cleaning agent commonly used at present, the cleaning agent has the advantages of abundant raw materials, low cost, cleanness and high efficiency, can improve the corrosion resistance and the surface dyne value of the steel shell, and improves the production benefit of the battery.
The alkaline zinc-manganese battery nickel pre-plating steel shell cleaning agent is prepared through the following steps:
s1, taking potassium hydroxide, an anionic surfactant and a double-ion surfactant for standby;

The mechanism of the invention is as follows: under alkaline condition, the potassium hydroxide and the oil stain remained on the surface of the steel shell are subjected to saponification reaction, and meanwhile, the surfactant has an emulsifying effect, so that the oil stain on the surface of the steel shell is cooperatively and effectively cleaned. The higher cleaning environment temperature is favorable for saponification reaction between strong alkali and grease macromolecules, promotes the grease on the surface of the steel shell to be decomposed into micromolecular substances, ensures that the surfactant is easier to adsorb and remove pollutants on the surface of the steel shell, enhances the cleaning effect and ensures that the surface of the steel shell is cleaner. Meanwhile, the composite surfactant can be adsorbed on the surface of the steel shell to form a protective layer, so that the reattachment of pollutants is prevented, and the corrosion of the steel shell can be slowed down to a certain extent. The formed clean steel shell surface is more favorable for the adhesion of the sealing agent, so that the sealing effect is better, and the rust resistance of the steel shell is improved. In addition, the passivation effect of alkali on metal can also effectively inhibit corrosion of the steel shell.
In the aspect of the synergistic effect of the composite surfactant, the double-ion surfactant has solubilization effect on the anionic surfactant, so that the concentration of the surfactant in the water phase can be increased, and the cleaning effect can be further improved. The cationic groups in the double-ionic surfactant and the anionic groups in the anionic surfactant have stronger interaction, so that the active agent components are caused to be closely arranged on the surface of the steel shell, the adsorption quantity is increased, the interfacial activity is increased, and the surface tension is enhanced, thereby improving the dyne value.

(3) Polarization curve test: the steel shells of comparative example 1 and example 4 were assembled into a step three electrode system and polarization curves were recorded by electrochemical workstation (Shanghai Chenhua CHI760E, china) test, scanning forward from-1.2V to-0.8V at a scan rate of 1.0mV s -1 And its corrosion current density and corrosion potential were calculated from the polarization curve.
(4) Corrosion resistance test: the steel shells of comparative example 1 and example 4 were assembled into a three-electrode system, a voltage of-1.0V was applied by an electrochemical workstation (Shanghai Chenhua CHI760E, china) and tested to record their electrochemical impedance, and their corrosion resistance was calculated according to an equivalent circuit diagram fit.
FIG. 1 is a scanning electron microscope image of an unpressed nickel plated steel strip (a), an unwashed steel shell (b) after stamping, a comparative example 1 steel shell (c) and an example 4 steel shell (d). From the figure it can be seen that the unwashed steel shell surface after stamping has more oil and fine contaminants, comparative example 1 has most of the dirt washed away, but has little residue, whereas the dirt of example 4 has almost all been washed away.
Fig. 2 is an atomic force microscope scan and three-dimensional reconstruction of unwashed steel shells (a, d) after stamping, comparative example 1 steel shells (b, e) and example 4 steel shells (c, f). The figure shows that the unslotted steel shell has larger concave-convex fluctuation, which indicates that more pollutant exists on the surface of the unslotted steel shell, the surface of the steel shell is obviously flattened after being washed, and the flatness of the steel shell of the example 4 is higher than that of the steel shell of the comparative example 1, which further indicates that the cleaning agent has cleaning capability superior to that of a commercial cleaning agent.
Fig. 3 shows the rust on the inner and outer surfaces of two sets of steel shells after salt spray testing. The inner and outer surfaces of the steel shell of comparative example 1 are obviously rusted, while the inner and outer surfaces of the steel shell of example 4 are hardly rusted, and the steel shell has excellent corrosion resistance.
FIG. 4 is the polarization curves and the polarization curves of the steel shells of comparative example 1 and example 4Testing the reaction condition of the process. From the polarization curve, the corrosion current of the steel shell of example 4 was 0.075mA cm -2 Less than comparative example 1 (0.083 mA cm -2 ) Indicating that the corrosion resistance is stronger. In addition, example 4, which has a corrosion potential of-1.011V and more negative than that of comparative example 1 (-0.996V), shows that example 4 mainly suppresses cathodic polarization, i.e., suppresses hydrogen evolution corrosion, and the difference in the number of bubbles generated in the reaction profile is also indicative.
FIG. 5 shows that the electrochemical impedance profiles of the steel shells of comparative example 1 and example 4 at an applied voltage of-1.0V can be matched to the results of the fit of the equivalent circuit in the inset, and that the corrosion resistance of the steel shells of example 4 is calculated to be 109.90 Ω (where the ohmic resistance R w =7.14Ω, membrane resistance R f =98.71 Ω, mass transfer impedance R ct =4.05Ω), whereas the corrosion resistance of the comparative steel can was only 69.63 Ω (R w ＝7.78Ω，R f ＝24.32Ω，R ct =37.53 Ω), which indicates that the steel shell of example 4 is more corrosion resistant.
Fig. 6 shows contact angles of unwashed steel shell (a), comparative example 1 steel shell (b) and example 4 steel shell (c) after stamping. The steel shell stamped by the water-based drawing liquid has more hydrophilic pollutants remained on the surface, so the contact angle is smaller, the contact angle of the steel shell after cleaning is obviously increased, but the surface tension of the inner surface of the steel shell in example 4 is larger and the contact angle is smaller compared with that of the steel shell in comparative example 1.
Fig. 7 is a graph showing the dyne value test of comparative example 1 steel shell (a) and example 4 steel shell (b). The results of the dyne test also showed that the surface tension of the inner surface of the steel shell of example 4 was greater, the dyne value was 35, and the dyne value of the comparative example was only 33.
