Embodiment 1

[0032] The invention provides a novel method for making a battery label, comprising a face paper layer 1, a first glue layer 2, a PET film layer 3, a frosted lattice surface layer 4 and a second glue layer 5, wherein the PET film layer 3 and the frosted lattice surface Layer 4 together constitutes the PET layer, and the specific preparation process is as follows:

[0033] S1. Ingredients:

[0034] S1.1: Select the special stretch film for battery label for face paper layer 1, which has good extensibility and good printability; choose transparent PET release film for PET film layer 3; choose acrylic glue with a large molecular weight for glue, and choose a relatively hard glue system. For glue with moderate initial viscosity, filter it clean to ensure cleanliness. If the glue system is relatively hard, ensure that the grid will not disappear easily when used later;

[0035] S1.2: Treat the selected transparent PET release film with single-sided frosted grid marks, and set the ...

[0048] S1. Ingredients:

[0049] S1.1: Select the special stretch film for battery label for face paper layer 1, which has good extensibility and good printability; choose transparent PET release film for PET film layer 3; choose acrylic glue with a large molecular weight for glue, and choose a relatively hard glue system. For glue with moderate initial viscosity, filter it clean to ensure cleanliness. If the glue system is relatively hard, ensure that the grid will not disappear easily when used later;

[0050]S1.2: Treat the selected transparent PET release film with single-sided frosted grid marks, and set the d...

Embodiment 3

[0062] The invention provides a novel method for making a battery label, comprising a face paper layer 1, a first glue layer 2, a PET film layer 3, a frosted lattice surface layer 4 and a second glue layer 5, wherein the PET film layer 3 and the frosted lattice surface Layer 4 together constitutes the PET layer, and the specific preparation process is as follows:

[0063] S1. Ingredients:

[0064] S1.1: Select the special stretch film for battery label for face paper layer 1, which has good extensibility and good printability; choose transparent PET release film for PET film layer 3; choose acrylic glue with a large molecular weight for glue, and choose a relatively hard glue system. For glue with moderate initial viscosity, filter it clean to ensure cleanliness. If the glue system is relatively hard, ensure that the grid will not disappear easily when used later;

Abstract

The invention discloses a novel battery label manufacturing method, and particularly relates to the field of battery accessories. The novel battery label manufacturing method comprises the steps of S1, burdening, S2, filtering, S3, gluing, S4, drying, S5, laminating, S6, primary rolling, S7, secondary gluing, S8, secondary rolling, S9, small roll dividing, S10, typesetting and printing, and S11, shipping. A PET layer is arranged, a grid release film with the depth of 18-20 microns is selected, the printing appearance cannot be affected, the bubble exhaust effect is guaranteed, the later-period battery labeling positioning effect is guaranteed through the material with high light transmittance, generated bubbles are all exhausted and cannot be left on the contact face of a battery and a trademark no matter how the battery is repeatedly heated and charged, the problems of swelling and falling of the battery caused by bubbles released by thermal decomposition of the glue in multiple charging and discharging processes of the battery are effectively solved.

Description

technical field [0001] The invention relates to the technical field of battery accessories, and more specifically, the invention relates to a method for making a novel battery label. Background technique [0002] With the rise of the new energy industry, the demand for the battery industry in my country and the world is increasing, and the output of batteries is also increasing. For each battery or battery product, there is a battery label attached to highlight the relevant information of the battery. However, due to the multiple cycle charging process of the battery, thermal expansion and contraction will occur due to the influence of heating, and the surface of the battery label is prone to blistering, resulting in poor appearance of the battery label. Such trademarks mainly rely on foreign imports, and domestic rechargeable battery trademarks have been in the stage of how to solve the label blistering during charging. [0003] The battery industry is developing rapidly,...
