Problems solved by technology

[0002] In the current conventional formula and refining method of carbon-lead batteries, the maximum carbon black content can only account for 1% of the total proportion, which cannot reflect the efficacy of carbon-lead plates. When the carbon black content is high, it is very easy to appear refining and Inhomogeneity makes the filling operability of the lead paste very difficult, and the active material of the lead paste is prepared by conventional methods. During use, carbon black is easy to precipitate into the electrolyte and adhere to the rubber safety valve of the battery, causing the battery to open and close. Abnormal valve pressure, thus affecting the quality and service life of the battery

Embodiment 1

[0013] Step 1: Uniformly disperse 70Kg lead powder, 0.2Kg fiber, 0.2Kg lignin, 0.3Kg humic acid, 0.3Kg barium sulfate, 20Kg PVA solution and 4Kg carbon black for 5-45 minutes to prepare a paste;

[0014] Step 2: Add 5Kg of sulfuric acid to the paste of the first step at a uniform speed for preparation. The time for adding sulfuric acid is controlled within 20 minutes. When adding sulfuric acid, the temperature is controlled not to exceed 40°C, and the temperature during the entire preparation process does not exceed 60°C. After the carbon lead viscosity is stable, the modulation is ended.

Embodiment 2

[0016] Step 1: Uniformly disperse 75Kg lead powder, 0.2Kg fiber, 0.15Kg lignin, 0.15Kg humic acid, 1.5Kg barium sulfate, 15Kg PVA solution and 3Kg carbon black for 5-45 minutes to prepare a paste;

[0017] Step 2: Add 5Kg of sulfuric acid to the paste of the first step at a uniform speed for preparation. The time for adding sulfuric acid is controlled within 20 minutes. When adding sulfuric acid, the temperature is controlled not to exceed 40°C, and the temperature during the entire preparation process does not exceed 60°C. After the carbon lead viscosity is stable, the modulation is ended.

Embodiment 3

[0019] Step 1: uniformly disperse 80Kg lead powder, 0.1Kg fiber, 0.1Kg lignin, 0.3Kg humic acid, 1.5Kg barium sulfate, 5Kg PVA solution and 8Kg carbon black for 5-45 minutes to prepare a paste;

[0020] Step 2: Add 5Kg of sulfuric acid to the paste of the first step at a uniform speed for preparation. The time for adding sulfuric acid is controlled within 20 minutes. When adding sulfuric acid, the temperature is controlled not to exceed 40°C, and the temperature during the entire preparation process does not exceed 60°C. After the carbon lead viscosity is stable, the modulation is ended.

Abstract

The invention discloses a lead paste for carbon lead storage battery. The lead paste is prepared by the following raw materials of: by weight, 70-80 parts of lead powder with oxidisability being more than 73%, 0.02-0.2 part of fiber, 0.05-0.3 part of lignin, 0.05-0.3 part of humic acid, 0.3-1.5 parts of barium sulfate, 5-20 parts of a PVA solution with its content being 0.1-20%, 0.01-5 parts of sulfuric acid with its specific gravity being 1-1.4g/ml and 1-10 parts of carbon black. A preparation method of the lead paste contains steps of: preparing a paste, adding metered sulfuric acid into the prepared paste at uniform speed, modulating until the lead viscosity of carbon lead is stabilized. By the adoption of the formula and the preparation technology, the carbon distribution of the carbon lead paste can be uniform; the content of carbon black is raised up to more than 3%; and there will appear no carbon drawback. Therefore, advantages of carbon lead batteries can be fully presented.
