The front coating comprises the following components by weight of dry matters: 52 parts of modified starch, 7 parts of high molecular polymer, 0.3 part of cellulose and vegetable gum, a proper amount of buffer and a proper amount of auxiliary agent. The back coating comprises the following components by weight of dry matter: 1 part of high molecular polymer, 1-2 parts of cellulose and vegetable gum and a proper amount of buffer. The invention is applied to the battery, can reduce the contact resistance, improve the conductivity, and can also avoid the slurry leakage of the battery water, the perforation and the liquid leakage.
Description
Technical Field
The invention relates to coated paper used on a battery, in particular to coated paper of a mercury-free zinc-manganese battery.
Background
The existing coated paper used for zinc-manganese battery uses single-density special base paper as carrier, and one or two surfaces of the paper are coated with a coating, the component of the coating is modified starch as main material, and water-soluble high molecular compound and buffer agent and other auxiliary materials are added. The disadvantages of such coated papers are: for the coated paper with a single surface, the back surface of the coated paper has a large contact resistance with the battery positive electrode core material, and the conductivity of the coated paper is relatively poor. For the coated paper with double-sided coating, although the contact resistance can be reduced and the conductivity can be improved, the double-sided coating uses the same formula, and the defects are that: firstly, starch contains the aldehyde group in the back coating, contacts with manganese dioxide in the anodal core material, can play the reduction effect, reduces the activity of manganese dioxide, secondly during modified starch heavy current continuous discharge in the back coating, starch gelatinization lag, and the effect weakens, and the equipment of high-speed production battery adopts vacuum straw book thick liquid layer paper to go into a zinc section of thick bamboo, and starch in the back coating can drop, blocks up the straw, causes mechanical failure easily.
Disclosure of Invention
The invention aims to research mercury-free zinc-manganese battery slurry layer paper.
The invention aims to solve the technical problems that the existing zinc-manganese battery slurry layer paper has poor conductivity and starch in a back coating is easy to fall off.

the front coating comprises the following components in percentage by weight of dry matter: 50-60 parts of modified starch, 5-10 parts of high molecular polymer, 0.1-0.5 part of cellulose and vegetable gum, a proper amount of buffer and a proper amount of auxiliary agent;
the reverse coating comprises the following components in percentage by weight of dry matter: 1 part of high molecular polymer, 1-2 parts of cellulose and vegetable gum and a proper amount of buffer.
The invention is applied to the battery, can reduce the contact resistance, improve the conductivity, and can also avoid the slurry leakage and the perforation of the battery.
