Abstract
This invention provides a method for processing negative Zn paste of Hgless buckled batteries, in which, the Zn paste is composed of main materials and an additive, and the main materials include Hgless Zn powder and electrolyte characterizing that the additive of the Zn paste includes In2O and InOH, which is mixed with the Zn powder and electrolyte uniformly to a paste, that is the Hgless negative Zn paste.
Description
Technical field
The present invention relates to non-mercury button cell and preparation method thereof, specifically relate to negative zinc cream and preparation method thereof in a kind of non-mercury button cell.
Background technology
Non-mercury button cell is world today's hot issue, also is an industry difficult problem.It is key one ring of non-mercury button cell that negative zinc cream is made.
Negative zinc cream is made up of major ingredient and additive; major ingredient is selected zinc powder and electric liquid usually for use; all contain mercury in the zinc powder at first; because zinc is very unsettled in the electrolyte aqueous solution; separate out hydrogen easily and cause self discharge; when adding mercury in negative pole, mercury forms layer protective layer at zinc surface---and zinc amalgam, suppressed zinc and separate out hydrogen in electrolyte.But mercury can produce to a certain degree pollution to environment, so people begin to seek the substitute of mercury.Indium and barium can replacement for mercury, and initial many personages are towards this direction test, and current part personage can make non-mercury button cell, but effect is not satisfactory, shows the cost height, and rate of finished products is low.
Summary of the invention
The object of the present invention is to provide low effective non-mercury button cell negative zinc cream of a kind of cost and preparation method thereof.
The present invention is achieved in that negative zinc cream is made up of major ingredient and additive, major ingredient comprises mercury less zinc powder and electric liquid, comprise indium oxide and indium hydroxide in the additive, the component and the weight portion of described negative zinc cream are as follows: mercury less zinc powder 60～70, electric liquid 30～40, zinc oxide 0.3～1.0, polyacrylic acid 0.2～0.8, Sodium Polyacrylate 0.2～0.8, indium oxide 0.02～1.0, indium hydroxide 0.02～1.0.
Find to use separately indium, indium oxide or indium hydroxide through a large amount of experiments in the negative zinc cream additive, to the not significantly effect of corrosion that prevents zinc, and indium oxide and indium hydroxide mix the corrosion that use can well prevent zinc according to a certain percentage.Among the present invention in the additive of negative zinc cream the weight portion of indium oxide and indium hydroxide be 0.02～1.0.
The present invention is owing to be replaced by indium oxide and indium hydroxide with the mercury in the negative zinc cream or indium or barium, in the pollution that prevents from effectively to have reduced again when zinc is corroded in the battery to environment, also reduced the cost of non-mercury button cell.
