Embodiment 1

[0034] A kind of lead-free mercury-free alkaline button cell zinc paste is prepared by following steps:

[0035] First, add 43kg of pure water into the distribution electrolyte tank, then add 55kg of potassium hydroxide into the distribution electrolyte tank under stirring, let it dissolve, and then add 7.536KG of zinc oxide into the distribution under stirring Let it dissolve in the electrolyte tank, and after the solution is cooled to normal temperature, adjust the hydroxide ion in the solution to 50% with pure water to obtain the electrolyte, and set aside;

[0036] Then, put 9.42Kg lead-free mercury-free zinc powder, 0.1Kg polyacrylic acid, 0.15Kg polyacrylate and 0.4Kg indium hydroxide into the stirring tank of the zinc mixer, stir and mix for 8 minutes to obtain the zinc powder mixture, and then 3.4 The electrolytic solution of Kg was slowly added in the stirring tank, stirred for 28 minutes, and stopped stirring;

[0037] Finally, evacuate until the index of the vacuu...

Embodiment 2

[0039] A kind of lead-free mercury-free alkaline button cell zinc paste is prepared by following steps:

[0040] First, add 38kg of pure water into the distribution electrolyte tank, then add 55kg of potassium hydroxide into the distribution electrolyte tank under stirring, let it dissolve, and then add 7KG of zinc oxide into the distribution electrolyte tank under stirring Let it dissolve in the liquid tank. After the solution is cooled to normal temperature, adjust the hydroxide ion in the solution to 50% with pure water to obtain an electrolyte solution for later use;

[0041] Then, 9.1Kg lead-free and mercury-free zinc powder, 0.15Kg polyacrylic acid, 0.15Kg polyacrylate and 0.6Kg indium hydroxide are put into the stirring tank of the zinc mixing machine, stir and mix for 5 minutes to obtain the zinc powder mixture, and then 3.1 The electrolytic solution of Kg was slowly added in the stirring tank, stirred for 20 minutes, and stopped stirring;

[0042] Finally, evacuate ...

Embodiment 3

[0044] A kind of lead-free mercury-free alkaline button cell zinc paste is prepared by following steps:

[0045] First, add 42kg of pure water into the distribution electrolyte tank, then add 50kg of potassium hydroxide into the distribution electrolyte tank under stirring, let it dissolve, and then add 8KG zinc oxide into the distribution electrolyte tank while stirring Let it dissolve in the liquid tank. After the solution is cooled to normal temperature, adjust the hydroxide ion in the solution to 50% with pure water to obtain an electrolyte solution for later use;

[0046] Then, 9.3Kg lead-free and mercury-free zinc powder, 0.1Kg polyacrylic acid, 0.1Kg polyacrylate and 0.5Kg indium hydroxide are put into the mixing tank of the zinc mixing machine, stirred and mixed for 7 minutes to obtain the zinc powder mixture, and then 3.3 The electrolytic solution of Kg was slowly added in the stirring tank, stirred for 20 minutes, and stopped stirring;

[0047] Finally, evacuate un...

Abstract

The invention relates to the technical field of battery manufacture, in particular to lead-free and mercury-free alkali button battery zinc cream and a preparation method thereof. The invention solves the problem of pollution of lead and mercury in a battery in the prior art. The invention adopts the technical scheme that: the lead-free and mercury-free alkali button battery zinc cream is characterized in that the zinc cream is formed by mixing and stirring zinc powder mixture and electrolyte; and the zinc powder mixture is formed by mixing lead-free and mercury-free zinc powder, polyacrylic acid, polyacrylic ester and indium hydroxide. Compared with the prior art, the invention has the following advantages that: the prepared zinc cream does not contain lead and mercury and has good explosion-proof function, and the preparation method is simple and has high production efficiency.

Description

technical field [0001] The invention relates to the technical field of battery manufacturing, in particular to a lead-free and mercury-free alkaline button battery zinc paste and a preparation method thereof. Background technique [0002] Batteries are popular for their portability and practicability. According to our survey, waste batteries contain a large amount of heavy metals and electrolyte solutions such as waste acids and alkalis. If discarded at will, corrupt batteries will destroy our water sources, erode the crops and land we depend on for survival, and our living environment is facing a huge threat. If a No. 1 battery rots in the ground, its toxic substances can make one square meter of land useless; throw a button battery into the water, and the toxic substances contained in it will cause 600,000 liters of water to be destroyed. Pollution is equivalent to a person's lifetime water consumption; waste batteries contain heavy metals such as lead, mercury, cadmium, ...
