The invention provides solvent-resistant protective film preparation equipment applied to the technical field of batteries. A primary thickness control gap is formed between a coating smooth roller (1) and a coating glue solution roller (2) of a coating part of the solvent-resistant protective film preparation equipment, and the coating glue solution roller (2) extends into a glue solution pool (3) located below the coating glue solution roller (2). C-shaped cleaning grooves (13) are formed in the lower portion of a left thickness shaping roller (4) and the lower portion of a right thickness shaping roller (5) which are arranged behind the coating glue liquid roller (2) respectively, and a baking oven (8) is arranged on the upper portion of the left thickness shaping roller (4) and the upper portion of the right thickness shaping roller (5). The solvent-resistant protective film preparation equipment has a simple structure, the thickness of the base material film layer adhered with the glue solution through the glue solution pool can be conveniently and reliably controlled, the thickness of the glue layer is ensured to be always within a set range through secondary thickness control, and the overall quality of the protective film is improved.
Description
technical field [0001] The invention belongs to the technical field of batteries, and more specifically relates to a preparation equipment for a solvent-resistant protective film, and also relates to a solvent-resistant protective film. Background technique [0002] In the field of battery technology, solvent-resistant protective films are required. However, a solvent-resistant protective film in the prior art includes a substrate film layer and an adhesive layer. When preparing for coating, glue is applied on the substrate layer, and then enters the oven for heating. However, because the film layer of the base material is passed through the glue pool to adhere the glue, and then the glue layer is formed, the thickness of the glue layer is poorly controlled. However, the overall thickness of the protective film is very thin, and the size control is in a very small range, requiring high precision. Contents of the invention [0003] The technical problem to be solved by t...
