Problems solved by technology

[0002] With the advancement of technology, the mechanization and automation of battery production are getting higher and higher, and the speed is getting faster and faster. The pulp paper produced by ordinary dry battery pulp paper base paper is easy to generate static electricity due to its high hardness. The high-speed production line produces batteries. Difficulty in feeding the pulp paper into the zinc cylinder, cracking of the pulp paper, powder falling, etc.
Seriously affect the normal performance of the production line, and the production of defective batteries and waste products increases; and the pulp paper produced by composite base paper increases the production cost due to its high price, and ordinary zinc-manganese dry batteries are unbearable. Therefore, it is necessary to The traditional pulp paper production process is reformed to meet the needs of high-speed battery production lines (≥600 pieces / min) to produce zinc-manganese dry batteries

Abstract

The invention relates to coated paper of a mercury-free zinc manganese dry cell for a high-speed battery production line and a preparation method thereof. The coated paper comprises base paper and coating layers coated on the front and the back of the base paper, i.e., double-layer coating. The base paper can adopt low tightness dry cell coated paper base paper, and the coated layer consists of modified starch, polyacrylamide, polyvinyl alcohol, carboxylated styrene-butadiene rubber latex, polyethylene glycol, propylene glycol block polyetherand and a compound corrosion inhibitor. The cell coated paper has good mechanical adaptability, strong antistatic ability, large liquid absorption capacity, high liquid absorption speed, good electrolyte retention and high isolation performance. The mercury-free zinc manganese dry cell produced by the coated paper has better electrical properties, and can meet the requirements of the mercury-free high-speed production line (600 cells per minute above) of zinc-manganese cells.
