A corresponding anion M can be two to five kinds of metal ions, such as Ca<2+>, mg<2+>, Cs<+>Li<+>, Na<+>, Al<3+>, Sn<2+>, In<3+>, Sb<3+>, Bi<3+>, Ga<3+>, Ce<3+>, La<3+>, Ag<+>, etc., and the addition quantity of the present invention in respect to zinc powder is from 0.005 to 5 wt. %. The present invention has the advantages of no toxicity and favorable effect of corrosion inhibition, and can be used as a corrosion inhibitor instead of mercury.

Description

Corrosion inhibitor as mercury substitute in a kind of alkaline zinc series cell
The present invention relates to alkaline zinc series cell, corrosion inhibitor as mercury substitute in the zinc series cell is provided especially.
Alkaline zinc series chemical power source, its anode are zinc, and negative electrode is manganese dioxide, silver oxide, mercury oxide, nickel oxide and air etc., and electrolyte then is alkaline solution.Alkaline zinc series cell is owing to advantage is subjected to people's such as capacity height, power be big favor, but exist more serious self-discharge phenomenon in the battery, usually add a certain amount of mercury (it is generally acknowledged and contain the basic demand that 3.6%Hg can satisfy the normal use of battery in the zinc powder).As everyone knows, mercury not only pollutes environment, and human body is also caused great harm.Along with the enhancing of environmental consciousness, replace mercury to become extremely urgent problem with low toxicity or nontoxic corrosion inhibiter.
People are usually by using anti-corrosion kirsite, adding the purpose that approach such as organic inhibition and inorganic inhibitor reach precipitate and remove mercury.In the patent No. is 4,735, and in 876 (1988) the United States Patent (USP), people such as Miura think that containing elements such as In, Al, Mg, Pb in the zinc powder can reduce mercury content in the zinc powder, and do not influence the normal use of battery.People's patent No.s such as Rossler are to point out in 4,195,120 (1980) the United States Patent (USP), and polyoxyethylene phosphate dissolves by generation and the zinc anode that absorption on zinc surface suppresses hydrogen, and its content is 0.001%-5% (with respect to zinc powder weight).People such as Katsuo are JP61 in the patent No., point out in 176,068 (1986) the Japan Patent, zinc powder is put into contained SnCL 2The aqueous solution in carry out one section of surface treatment to after, filtration, cleaning, drying, thus obtain the zinc powder that tin is contained on the surface, this zinc powder hydrogen-separating quantity in alkali lye obviously reduces.
The object of the present invention is to provide a kind of nontoxic and effective corrosion inhibitor as mercury substitute.
The invention provides corrosion inhibiter and mainly be composited by some inorganic compounds, its molecular formula is: M YX Z, its anionic group can be SO 4 2-, Cl -, PO 4 3-, SiO 3 2-, NO 3 -, SCN -, OH -, S 2-,, Tartaric acid root, citrate, metaphosphoric acid radical one or more, corresponding cation M can be Ca 2+, Mg 2+, Cs +, Li +, Na +, Al 3+, Sn 2+, In 3+, Sb 3+, Bi 3+, Ga 3+, Ce 3+, La 3+, Ag +Deng two in the metal ion to five kinds.Can directly add in the electric liquid or zinc powder is put into its aqueous solution carry out surface treatment, also can two kinds of methods have both at the same time, its content is 0.005-5% (with respect to zinc powder weight, difference).This corrosion inhibiter mainly by chemical reaction or absorption, deposits or is adsorbed in zinc surface, corrosion reaction is played slowed down effect.
Can add a kind of quaternary ammonium salt cationic corrosion inhibiter for further improving its corrosion mitigating effect, its molecular formula is R 1R 2R 3R 4NBr, wherein R 1-R 4Be alkyl or aromatic radical, it contains carbon number is 1-18, and its content is 0.0001-0.5% as corrosion inhibiter 2 because its surface activity is adsorbed on electrode and the solution interface obstruction H 2O and OH -To the electrode surface diffusion, thereby inhibitory action is played in zinc anode dissolving and cathode hydrogen evolution reaction.This quaternary ammonium salt cationic corrosion inhibiter also can add separately, certainly the effect relative mistake some.
Below by embodiment in detail the present invention is described in detail
Example 1
Electrolyte solution adopts the 40%KOH solution that contains a little zinc hydrochlorate; Sample zinc granule degree is the 150-200 order, and purity is 99.995%, and sampling amount is 1.0g; Experimental temperature is 50 ± 1 ℃, and following example all carries out under above-mentioned experiment condition.
In electric liquid, add by La 2(SO 4) 3Corrosion inhibiter 1 (content is 0.3%) with the sodium metaphosphate composition, after zinc powder stored 14 days therein, recording hydrogen-separating quantity is 0.95ml, zinc powder is (being blank solution) in the solution that does not contain corrosion inhibiter, hydrogen-separating quantity is 13.4ml in during identical, and the zinc powder that contains Hg4% in blank solution under the same conditions, hydrogen-separating quantity is 0.41ml.
Embodiment 2 is containing zinc powder by CeCl 30.3%, CsOH0.6%, GaCl 30.7%, AgNO 3Carry out surface treatment in the aqueous solution of the corrosion inhibiter 1 of composition such as 0.4%, store 14 days then in alkali lye, recording hydrogen-separating quantity is 0.45ml, near the liberation of hydrogen level that contains the zinc powder of Hg4%.
Embodiment 3 adds softex kw (content is 0.02%) in electric liquid, zinc powder between 14 day storage life in hydrogen-separating quantity be 2.55ml.
Embodiment 4 will handle the zinc powder obtain by example 2 methods put into the alkali lye that contains 0.03% corrosion inhibiter 2, between 14 days storage life in hydrogen-separating quantity be 0.35ml, be better than containing the corrosion mitigating effect of Hg4% zinc powder.
Embodiment 5 in alkali lye, add with example 1 in same composition and content corrosion inhibiter 1 and with example 3 in the corrosion inhibiter 2 of same amount, zinc powder hydrogen-separating quantity in 14 days storage life is 0.55ml, is better than the effect of adding two kinds of corrosion inhibiter separately.
