Embodiment 1
[0045] A kind of lead-acid storage battery cathode lead paste and preparation method, comprise following preparation steps:
[0046] (1) The first step: combine the part lead powder accounting for 60% of the total lead powder weight with the short fiber (the length of the short fiber is 4mm) accounting for 0.15% of the total lead powder weight, the graphite accounting for 0.3% of the total lead powder weight and the The red lead of 2.5% of total lead powder weight is mixed evenly, then 40s add the pure water that accounts for 14.5% of total lead powder weight, wet mix 18min after adding water, add the sulfuric acid that accounts for total lead powder weight 8% again (the density of sulfuric acid is 1.5g / cm 3 ) for acid mixing, the acid mixing time is 40 minutes to form a semi-suspension slurry, after the acid addition is completed, 90°C high-temperature steam is introduced to heat the semi-suspension slurry and stir for 25 minutes to obtain slurry A;
[0047] (2) The second ...
Embodiment 2
[0050] A kind of lead-acid storage battery cathode lead paste and preparation method, comprise following preparation steps:
[0051] (1) The first step: combine the part lead powder accounting for 40% of the total lead powder weight with the short fiber (the length of the short fiber is 6mm) accounting for 0.05% of the total lead powder weight, the graphite accounting for 0.1% of the total lead powder weight and the Mix the red lead with 5% of the total lead powder weight evenly, then add 13.5% pure water accounting for the total lead powder weight for 20 seconds, wet mix for 5 minutes after adding water, then add 10% sulfuric acid (the density of sulfuric acid is 1.4g) / cm 3 ) for acid mixing, and the acid mixing time is 15 minutes to form a semi-suspension slurry. After the addition of acid, high-temperature steam at 80° C. is introduced to heat the semi-suspension slurry and stir for 30 minutes to obtain slurry A;
