Embodiment 1

[0009] Embodiment 1: The dry battery pulp paper film-forming glue of the present invention is formed by copolymerization of vinyl acetate and alkenyl acid. In terms of weight percentage, one part of vinyl acetate is matched with one part of alkenyl acid. Alkenyl acid is selected from acrylic acid and crotonic acid, and the mutual consumption ratio of the two kinds of acids can be determined arbitrarily.

[0010] The above-mentioned production process of dry cell pulp paper film-forming adhesive is that vinyl acetate and alkenyl acid are copolymerized, followed by saponification reaction, and finally film-forming adhesive is obtained.

Embodiment 2

[0011] Embodiment 2: The dry battery pulp paper film-forming adhesive of the present invention is formed by copolymerization of vinyl acetate and alkenyl acid. In terms of weight percentage, one part of vinyl acetate is matched with two parts of alkenyl acid. Alkenyl acid is selected from acrylic acid.

[0012] The above-mentioned production process of dry cell pulp paper film-forming adhesive is that vinyl acetate and alkenyl acid are copolymerized, followed by saponification reaction, and finally film-forming adhesive is obtained.

[0013] In addition to the acrylic acid and crotonic acid in Embodiment 1 and Embodiment 2, the alkenyl acid of the present invention also includes acrylamide, and one or two or all three of them can be used. When two or three of them are selected When species, the mutual dosage ratio can be determined arbitrarily.

Abstract

The present invention relates to a kind of film formation colla with dry cell paste layer, which is formed by vinyl acetate and alkenyl acid. According to wt. percentage, 1. vinyl acetate: 3 alkenyl acid, alkenyl acid comprises acroleic acid, butemic acid or acrylamide, either choosing and applying one or the other or all for usage. When choosing from among them, two or three, the ratio in relation to each other can be freely determined. The productive technological process of the said film formation colla with dry cell paste layer lies in the fact that the film formation colla is finally made with the mixture of vingl acetate and alkenyl acid and through saponificaiton. The coating paper made by the film formation colla in this invention used in the dry cell production can provide stability for the dry cell thus produced and the storage last longer and the quality of dry cell can be highly improved.

Description

technical field [0001] The invention relates to a conductive adhesive, in particular to a film-forming adhesive for dry battery pulp layer paper. Background technique [0002] The existing film-forming glue used for dry battery pulp paper has poor water solubility. After using this film-forming glue in battery production, there is a problem that the stability of the battery is poor and the quality of the battery is affected. Contents of the invention [0003] The purpose of the invention is to develop a dry battery pulp layer paper film-forming glue. [0004] The present invention aims to solve the technical problems that the existing dry battery pulp paper film-forming adhesive has poor water solubility, which causes poor internal resistance stability and low battery quality of the pulp paper coated with the film-forming adhesive. [0005] The dry battery pulp layer paper film-forming glue of the present invention is formed by copolyme...
