Embodiment 1

[0028] The coated board paper is made of the following raw material proportions by weight: 45 parts of long-fiber wood pulp, 25 parts of hemp pulp, 10 parts of chemical fiber, 1 part of wet strength agent, and 0.2 part of PEO dispersant.

[0029] Further, the long-fiber wood pulp is coniferous wood pulp, and is thick long-fiber wood pulp in coniferous wood.

[0030] Further, hemp pulp is Manila hemp pulp.

[0031] Further, the chemical fibers are viscose fibers.

[0032] Further, the wet strength agent is polyester amide.

[0033] Further, the PEO dispersant is polyoxyethylene.

[0034] Further, the above-mentioned production method of coated paper comprises the following steps:

[0035] The first step is raw water treatment. Tap water is first filtered twice with a sand filter, then filtered for the third time with a honeycomb filter, and then purified by a reverse osmosis water purifier to obtain raw water. At this time, the COD index of the raw water is 12 ;

Abstract

The invention provides pasting paper and a production method thereof. The pasting paper is prepared from raw materials including long-fiber wood pulp, hemp pulp, chemical fibers, a wet strength agent and a PEO (polyoxyethylene) dispersing agent through steps including raw water processing, beating, auxiliary adding, papermaking, coating and finished paper forming. The pasting paper and the production method have the benefits as follows: the produced pasting paper has good dry strength and wet strength, can meet the strength requirement in follow-up processing and actual use, has good acid solubility, low ash content, liquid absorption and air permeability and can be totally dissolved under the action of strong acid without residues; electrolyte in a storage battery can be permeated uniformly, electrons exchange effectively, the usability of the storage battery is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a coated paper and a production method thereof. Background technique [0002] Coated paper is mainly used in the pasting process of the lead-acid battery plate, and it is the paper for the guard plate in the paste process of the lead-acid battery plate. [0003] The performance index of coated paper is high, the material selection is exquisite, the manufacturing process is complicated, and the technology is difficult. At present, the coated paper on the market mainly has low strength, excessive ash content, poor acid solubility, poor liquid absorption, single-sided light, poor air permeability, etc. Shortcomings, therefore, need a kind of coated board paper that can solve these defectives urgently on the market. Contents of the invention [0004] The present invention aims to solve the problems existing in the above-mentioned prior art, and provides a coated paper and its ...
