Automobile lead-acid battery positive and negative anti-corrosion protection spray and its production process

Abstract

An anticorrosion protective spray for automobile lead-acid battery positive and negative electrode tabs and a production process thereof relate to an anticorrosion protective spray, comprising the following materials: 10-15% of polytetrafluoroethylene micro powder, 20-25% of glycol, 10-15% of copper oleate, 10-15% of polyvinyl butyral, 20-25% of a curing diluting solvent, and 10-15% of LPG propellant; the preparation process includes the following steps: A, injecting the polytetrafluoroethylene micro powder into a stirring barrel, stirring well, and adding the glycol and mixing well; B, adding the curing diluting solvent, and mixing well; C, adding the copper oleate, and stirring to obtain liquid material; D, charging the blended liquid material into a spray packaging bottle according to quantitative standard; E, charging the LPG propellant quantitatively into the spray packaging bottle. A high-temperature-resistant thin film formed by spraying the spray can protect a battery head, a charge clamp and a circuit connector from oxidization and can maintain good conductivity in battery positive and negative electrodes for a long time.

Description

technical field [0001] The invention relates to an anti-corrosion protection spray, in particular to an anti-corrosion protection spray for positive and negative poles of lead-acid batteries used in automobiles and a production process thereof. Background technique [0002] Car batteries are an essential part of cars and can be divided into traditional lead-acid batteries and maintenance-free batteries. The structure of the car battery is mainly composed of positive (negative) plate, separator, electrolyte, tank shell, connecting strip and pole pile. Since the lead-acid battery will evaporate water in the electrolyte when the car is started and charged, the released sulfuric acid gas will corrode the positive and negative terminals of the battery and the power connection wires. Long-term corrosion will cause the positive and negative terminals of the battery and the power connection wires The acid corrosion of the battery will affect the starting of the car, resulting in an...

Since the lead-acid battery will evaporate the water in the electrolyte when the car is started and charged, the released sulfuric acid gas will corrode the positive and negative terminals of the battery and the power connection wires. Long-term corrosion will cause the positive and negative terminals of the battery and the power connection wires The acid corrosion of the car affects the starting of the car, resulting in an instantaneous impedance and voltage drop during charging
