Description

Preparation method of pulp-coated paper for leak-proof mercury-free battery
Technical Field
The invention relates to the technical field of dry battery manufacturing, in particular to a preparation method of coated paper for a leakage-proof mercury-free battery.
Background
The negative electrode of the acid zinc-manganese dry battery is a zinc cylinder which is amalgamated to ensure that the surface property is more uniform, reduce the corrosion of zinc and improve the storage performance of the battery; the positive electrode material is a mixed paste composed of manganese dioxide powder, ammonium chloride and carbon black.
Since the hydrogen evolution overpotential of the zinc amalgam alloy formed by mercury and zinc in water environment is high, people always adopt mercury as a corrosion inhibitor to slow down the self-corrosion rate of a zinc electrode and obviously improve the storage period of the battery for a long time. In addition, the added metal mercury enables the anode to be in better contact, reduces the internal resistance of the battery and can also improve the anti-seismic performance of the battery. However, mercury is extremely toxic and volatile, strict protection measures must be taken in the production process, the post-treatment process of waste batteries and the like, otherwise mercury leaks into water and soil, enters organisms by virtue of food chains, and finally flows into human bodies to cause mercury poisoning, for example, chronic poisoning often causes obvious neurasthenia, sensory disturbance and mental disturbance, severe poisoning encephalopathy and hepatopathy and has obvious embryotoxicity.
In addition, whether the battery performance of the zinc-manganese dry battery can meet the standard requirements depends not only on the corrosion inhibition performance of the selected corrosion inhibitor, but also has a direct relation with the performance of the used coated paper. The pulp paper is used as a diaphragm for separating the positive electrode and the negative electrode in the battery, and the addition of the pulp paper ensures that materials of the two electrodes cannot be in direct contact with each other and that electrolyte can smoothly pass through the pulp paper to absorb certain electrolyte when the battery works normally, so that the current amount in the period is kept smooth. The manufactured coated paper meets the following technical requirements: the isolation is good, the positive electrode and the negative electrode can be well separated, and the passing of the electric core particles is prevented; the ion permeability is good, and conductive ions can pass through the battery smoothly when the battery works; the chemical stability is good, side reactions such as hydrolysis, segregation and degradation do not occur in the acid electrolyte, and the storage is easy; good liquid absorption and retention, can absorb more electrolyte and prolong the service life of the battery. The existing coated paper generally consists of base paper, an adhesive, a liquid retention agent, a paste material, an auxiliary additive and the like, generally has the problems of low liquid absorption speed, small liquid absorption amount, poor isolation performance, poor electrical performance and the like, and has great significance in researching green, environment-friendly, corrosion-inhibition and leakage-proof zinc-manganese battery coated paper in order to eliminate the ecological damage problem caused by mercury pollution and slow down the self-corrosion rate of a zinc electrode.
