Abstract

The invention discloses a button cell protective film convenient to mount. W-like grooves are formed in a matte black polyester film layer, a first 3M adhesive layer and a PET release film layer, the sizes of the matte black polyester film layer, the first 3M adhesive layer, a black polyester film layer, a second 3M adhesive layer and self-contained adhesive are all not larger than the size of the PET release film layer, and the size of the self-contained adhesive is not larger than the second 3M adhesive layer. According to the button cell protective film convenient to mount, the matte black polyester film layer, the 3M adhesive layers, the black polyester film layer and the self-contained adhesive are bonded together through the two 3M adhesive layers and the self-contained adhesive, and the button cell protective film can be efficiently mounted on a button cell through the two 3M adhesive layers after the PET release film layer is quickly torn off. The protective film has good shading performance, electrical insulation performance, heat resistance, waterproofness and the like, is good in adhesion performance and adhesiveness, plays a good role in protecting the button cell, and is simple in overall structure, attractive and elegant.

Description

technical field [0001] The invention belongs to the technical field of button battery protective films, and in particular relates to a button battery protective film which is convenient for mounting. Background technique [0002] The protective film of the button battery can protect the battery core, prevent the battery from being scratched or punctured by external forces and cause a fire due to battery leakage, thereby ensuring the stability and safety of use. However, the functionality of the existing button battery protective film needs to be improved, and the mounting process is inconvenient and inconvenient to use. Contents of the invention [0003] In order to solve the problems in the prior art, the object of the present invention is to provide a button cell protective film which is convenient for mounting. [0004] In order to achieve the above object and achieve the above technical effect, the technical solution adopted in the present invention is: [0005] A bu...
