Abstract

A lead paste formula for forklift truck battery and its preparation process are disclosed, 100 kg of lead powder, 11.5 kg of sulfuric acid, 12-13 kg of pure water, 80 g of chemical short fib, 300 g ofcalcium sulfate, 200 g of tin sulfate, 200 g of glycerol, 100 g of antifreeze and 0. 5-1 kg of cooling water; 100kg of lead powder, 11.5 kg of sulfuric acid, 10-11kg of pure water, 90g of semi-charcoal sawdust, 70g of sodium dodecyl sulfonate, 60g of pore-forming agent, 600g of tannin extract and 50g of diffusion agent; As that antifreeze is added in the invention, the lead paste is avoid from freezing in a cold area and can not work normally, and the charging acceptance capacity and the cycle life of the battery can be improved by adding tin sulfate.

Description

Technical field: [0001] The invention relates to the field of storage batteries, in particular to a formula of battery lead paste for forklifts and a preparation process thereof. Background technique: [0002] A storage battery is a device that directly converts chemical energy into electrical energy. It is a battery designed to be rechargeable. It is recharged through a reversible chemical reaction. It usually refers to a lead-acid battery, which is a type of battery. , belonging to the secondary battery. Its working principle: when charging, the external electric energy is used to regenerate the internal active material, the electric energy is stored as chemical energy, and the chemical energy is converted into electric energy output again when it needs to be discharged, such as mobile phone batteries commonly used in life. With the increasing quantity and the promotion of the application range, the quality of the storage battery has also become a problem. Many storage ba...
