Abstract

The invention relates to the technical field of protection film adhesive tapes, and concretely to a UV visbreaking protection film for lithium battery packaging, and a preparation method thereof. TheUV visbreaking protection film for lithium battery packaging comprises a substrate film, a UV visbreaking layer and a release film which are sequentially arranged, the UV visbreaking layer is a layerof an acrylate pressure sensitive adhesive containing a double bond in the branch chain, the UV visbreaking layer is obtained by drying a UV visbreaking glue, and the UV visbreaking glue comprises theacrylate pressure sensitive adhesive containing the double bond in the branch chain, a crosslinker, a light Initiator and a solvent. The UV visbreaking protection film realizes UV light visbreaking with only a single glue, so the problems of low production efficiency and residual glue in the use process of a traditional protection film are solved, and the problem of non-stability of existing UV visbreaking adhesives is also solved. The preparation method has a simple process, do not need harsh production conditions or devices, is especially suitable for large-scale mass production, and has great economic benefits.

Description

technical field [0001] The invention relates to the technical field of protective film tapes, in particular to a UV viscous-reducing protective film used for lithium battery packaging and a preparation method thereof. Background technique [0002] During the production, assembly and transportation of precision electronic products such as lithium batteries and LCD screens, the surface is usually covered with a protective film to avoid contamination or damage. However, after the traditional protective film is used, it needs to be torn off manually, which hinders the automatic production and reduces the production efficiency. , It is easy to leave residual glue on the surface of the product, which affects the appearance of the product, and increases the workload of additional cleaning and glue removal. [0003] At present, in the research in the field of UV viscosity-reducing pressure-sensitive adhesives, the main focus is on adding multifunctional acrylates to acrylate-based ...
