Problems solved by technology

Pulp layer paper produced by ordinary technology generally has the characteristics of high hardness and is prone to static electricity. In addition, during the production of batteries on high-speed battery production lines, the pulp layer paper is often broken, difficult to feed into the zinc cylinder, and powder falls, which seriously affects The normal performance of the high-speed battery production line has resulted in an increase in defective and waste batteries
However, the pulp paper produced by composite base paper increases the production cost due to its high price, which makes it difficult for ordinary zinc-manganese dry batteries to bear

Abstract

The invention provides a coated paper produced from K8 cable paper and used for high-speed battery production line and a preparation method thereof. The coated paper has base paper which is K8 cable paper, and a coating layer is coated on one surface of the base paper. The coating layer comprises the following components in percentage by weight: 45-50% of modified starch, 3-4% of polyacrylamide, 30-35% of instant gelatin silk, 1.5-2% of alkylphenol ethoxylates, 2.5-3% of dioctadecyl dimethyl ammonium chloride, 2.5-3.5% of polyethyleneimine, 4-5% ofhydroxyethyl cellulose and 2.5-3.5% of compound corrosion inhibitor. The coated paper disclosed by the invention has the advantage of low production cost, not only achieves good isolation performance and good water retainability which are required by dry cell production, but also can well reach the production process requirements of the high-speed battery production line with production capacity being not less than 800 per minute.

Description

technical field [0001] The invention relates to a pulp paper and a preparation method thereof, belonging to the technical field of dry battery manufacturing, in particular to a mercury-free zinc-manganese dry battery pulp paper for high-speed battery production lines (≥800 pieces / min) produced by using K8 cable paper and its preparation method. Background technique [0002] With the rise of labor costs, the proportion of labor costs in production costs has increased sharply, and the battery production industry is facing a situation of transformation from traditional labor-intensive industries to mechanized and highly automated labor-efficient industries. With the continuous advancement of production technology, the automation of battery production equipment is getting higher and higher, and the production speed is getting faster and faster. Pulp layer paper produced by ordinary technology generally has the characteristics of high hardness and is prone to static electricity....
