Embodiment 1

[0032] A cleaning agent for removing inkjet codes on the surface of an aluminum-plastic film, said cleaning agent comprising the following raw materials in weight percent: 70% pure water, 12% petroleum ether, 9% ethyl propionate, and 9% ethanol.

[0033] Use this cleaning agent to clean the soft-packed cells with barcodes printed on the surface of the aluminum-plastic film. The ink type used to print the barcodes is J199, and the manufacturer is Markem-Imaje. The cleaning method is as follows:

[0034] Use a dust-free paper dipped in the scrubbing reagent, and gently wipe the coded area of ​​the soft-packed battery; observe the state of the coded area of ​​the soft-packed battery in a bright place, and the un-coded area on the surface of the battery and the coded area before scrubbing For comparison, the result is as figure 1 As shown, it can be clearly seen from the figure that there is no inkjet residue on the surface of the battery cell after being wiped by the cleaning age...

Embodiment 2

[0036] A cleaning agent for removing inkjet coding on the surface of an aluminum-plastic film. The cleaning agent includes the following raw materials in weight percent: 65% pure water, 15% acetone, 10% dimethyl carbonate, and 10% ethanol.

[0037] Use this cleaning agent to clean the soft pack batteries with barcodes printed on the surface of the aluminum-plastic film. The ink type used to print the barcodes is MW133, and the manufacturer is Markem-Imaje. The cleaning method is as follows:

[0038] Use a dust-free paper dipped in the scrubbing reagent, and gently wipe the coded area of ​​the soft-packed battery; observe the state of the coded area of ​​the soft-packed battery in a bright place, and the un-coded area on the surface of the battery and the coded area before scrubbing For comparison, the result is as figure 2 As shown, it can be clearly seen from the figure that there is no inkjet residue on the surface of the battery cell after being wiped by the cleaning agent...

Embodiment 3

[0040] A cleaning agent for removing inkjet coding on the surface of an aluminum-plastic film. The cleaning agent includes the following raw materials in weight percent: 68% pure water, 7% acetonitrile, 10% ethyl propionate, and 15% ethanol.

[0041] Use this cleaning agent to clean the soft-packed batteries with barcodes printed on the surface of the aluminum-plastic film. The ink type used to print the barcodes is MB175, and the manufacturer is Markem-Imaje. The cleaning method is as follows:

[0042] Use a dust-free paper dipped in the scrubbing reagent, and gently wipe the coded area of ​​the soft-packed battery; observe the state of the coded area of ​​the soft-packed battery in a bright place, and the un-coded area on the surface of the battery and the coded area before scrubbing For comparison, the result is as image 3 As shown, it can be clearly seen from the figure that there is no inkjet residue on the surface of the battery cell after being wiped by the cleaning ag...

Abstract

The invention discloses a cleaning agent for removing printing ink sprayed codes on the surface of an aluminum plastic film and a use method of the cleaning agent. The cleaning agent comprises the following raw materials in percentage by weight: 65-75% of pure water, 5-15% of petroleum ether, 5-15% of an ester solvent and 5-15% of an alcohol solvent. The cleaning agent can be used for rapidly cleaning sprayed codes on the surface of the soft package battery cell without damaging an aluminum-plastic film coating on the surface of the soft package battery cell, so that the integrity of the appearance of the soft package battery cell is ensured, and the surface of the soft package battery cell meets the acceptance inspection requirement of the product appearance.

Description

technical field [0001] The invention relates to a cleaning agent for removing ink spray codes on the surface of an aluminum-plastic film and a use method thereof. Background technique [0002] During the manufacturing process of the soft-packed battery, the information of the battery is marked by inkjet coding on the aluminum-plastic film of the soft-packed battery. The bar code of the battery cell is of great significance. It not only allows users to quickly identify the material, capacity, voltage, and manufacturer's production batch number used in the battery cell, but also binds the process data of each process in the cell manufacturing process to achieve the purpose of cell traceability. . [0003] Aluminum-plastic film is the key material for flexible packaging lithium battery cell packaging. It has good barrier properties, electrolyte resistance stability, cold stamping formability, puncture resistance and insulation, high strength, high barrier, and extremely demand...
