Good performance and environmental protection effect.

Description

A battery label with an insulating edge seal

The utility model relates to a label, in particular to a battery label.

The battery labels that can be seen in the market now are generally aluminized film labels of PVC materials, which are wrapped on the surface of the battery and isolated from the outside world for protection, and the product name pattern is printed on it, especially for the battery. It is isolated from the outside world for insulation, but after the battery label is combined with ink layer, PVC layer, aluminum layer, self-adhesive layer and other layers, the edge of the aluminum layer is exposed to the air, and the conductivity of aluminum makes the battery Chronic leakage will still occur. There is also a double-layer PVC battery label, which puts the aluminum layer between two layers of PVC, but the edge of the aluminum layer will still inevitably be exposed to the air, and it may also be polluted by the external environment, such as humid air, In this case, the two poles of the battery will have a slight short circuit, which will not only cause discharge, but also due to the limitation of the material structure, alkaline solution will inevitably remain in the battery assembled on the production line, and the battery will generate electricity during transportation. The slight deformation of the battery body will aggravate the discharge and pollution. It is not difficult to understand that the performance of the battery will be greatly reduced after a long period of storage (such as one or two years) or even run out of power. It has brought severe problems and challenges. For today's industry and even the information society with higher and higher environmental protection requirements, it is imperative to solve the above defects.

The purpose of this utility model is to provide a new type of battery label with insulating edge sealing for the above-mentioned deficiencies in the prior art. This kind of battery label has an insulating material that seals the edge, so that the aluminum layer in the label layer is isolated from the air, and will not be affected by external air, human hands, etc., and resists the corrosion of the residual alkaline solution on the battery body, especially the excellent The insulation performance makes the battery no longer produce micro-discharge, greatly improves its service life and storage period, and has a very ideal environmental protection effect.

The technical scheme of the utility model is as follows: whether it is a single-layer PVC aluminum-plated label or a double-layer PVC aluminum-plated label, from the perspective of its section, it is composed of an ink protective layer, a printing ink layer, a PVC layer, an aluminum layer and a self-adhesive glue. Layers and other different layers are combined, and then die-cut into a certain shape and size according to requirements, and wrapped on the battery body. The utility model is to apply transparent insulation on the edge of the label near the two poles (positive and negative) of the battery. material layer, and tightly cover each layer, which not only solves the problem of aluminum layer exposure, but also protects each layer tightly, which is conducive to the hygiene and environmental protection requirements during use. The insulating layer at both ends of the label has good insulation protection performance , effectively resist the pollution and erosion of various substances.

According to the utility model of the above-mentioned technical solution, the edge-sealing insulating material has good transparency, which does not affect the appearance of the label at all. The most important thing is that it isolates the aluminum layer from the air and is not affected by air humidity, human hands, and sweat stains. , The impact of residual alkaline substances in the battery, even if the battery body is slightly deformed during transportation and use, it will not cause battery leakage. If the storage time is too long, the self-adhesive glue will deform, overflow and run away, which improves the service life and storage period of the battery, making it have good performance and environmental protection effect. Experiments have proved that after the label is soaked in potassium hydroxide solution for several hours, the aluminum layer of the label will not be corroded, which shows its corrosion resistance.

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.

Accompanying drawing 1 is the longitudinal sectional schematic diagram after the conventional single-layer PVC battery label layer enlargement;

Accompanying drawing 2 is the longitudinal sectional schematic diagram after the conventional double-layer PVC battery label layer enlargement;

Accompanying drawing 3 is the schematic diagram of longitudinal section of label after the utility model enlargement;

Accompanying drawing 4 is the use status diagram after the enlargement of the utility model;

It can be seen from Figure 1 and Figure 2 that conventional battery labels are composed of ink protective layer 1, printing ink layer 2, PVC layer 3, aluminum layer 4, and self-adhesive layer 5. One of them is PVC One layer, the other is to divide the PVC into upper and lower layers, and the aluminum layer 4 is wrapped in it, but it can be seen from the figure, but no matter what kind of structure, the edge part of the aluminum layer 4 is inevitably exposed in the air. After they are die-cut and molded according to the requirements, they are wrapped on the battery body. The conductivity of the aluminum layer causes the positive and negative poles of the battery to be short-circuited to produce a slight discharge. If the battery body is slightly deformed during use, the discharge will be more obvious.

It can be seen from Fig. 3 and Fig. 4 that the utility model is to apply an insulating material layer 6 on the sealing edges close to the two poles of the battery on the label, and tightly wrap each layer, and after packaging on the battery body 7, its positive and negative The two poles are insulated and disconnected, which solves the problem that the aluminum layer is exposed to produce discharge, and the entire label is tightly protected at all levels, which is conducive to the hygiene and environmental protection requirements during use. The insulating layers at both ends of the label have good insulation protection performance. Resisted the pollution and erosion of various substances.

Because of its good transparency, the insulating material layer 6 will not affect the aesthetic appearance of the label at all.
