Abstract

The invention provides a neutral repair liquid for a lead-acid battery and a preparation technology of the neutral repair liquid. The preparation technology comprises specific steps as follows: a heating kettle is heated to 85-95 DEG C, haloid acid, a polymer and magnesium oxide are added to deionized water and stirred uniformly, and a primary combined liquid is generated; heat preservation is performed for 70-90 min, other raw materials are added with stirring, and a secondary combined liquid is generated; heat preservation is performed for 70-90 min, then tartaric acid and calcium chloride are added and heated with stirring, and a semitransparent viscous solution, namely, the repair liquid for the lead-acid battery is obtained. Capacity restoration rate of the battery repaired by the repair liquid is high; battery capacity restores quickly, and capacity of the battery even with slight physical damage can be also increased greatly; the repair liquid has a prevention function, the effective reaction period can be as long as 1 year or longer after being added to the battery for repair, and accordingly, sulfate formation can be delayed in a long term; the repair liquid is neutral inchemical property, has no adverse effects on a human body and the environment and is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of battery repair, in particular to a lead-acid battery neutral repair solution and a preparation process thereof. Background technique [0002] Lead-acid batteries are widely used in various fields due to their low internal impedance and low manufacturing cost. However, during the long-term storage and use of batteries, sulfates will precipitate on the surface of the plates and gradually cover the surfaces of the plates. The sulfate has a very strong impedance. The sulfate attached to the surface of the plate hinders the conductivity of the plate and increases the internal impedance of the lead-acid battery. The charging current becomes smaller due to the limitation, causing the battery to stop before it is fully charged. Charge. Keep the storage battery in a state of insufficient capacity, and continuously precipitate sulfate, which will sharply reduce the performance of the battery, and the density of su...
