Abstract

The invention discloses a production method of a multifunctional MLCC release film base film. The base film comprises an outer surface layer, a middle core layer and an inner surface layer. The outer surface layer is prepared from PET, ABS, PC, an antioxidant, PE-g-MAH, PBT, glass fibers and talcum powder; the middle core layer is prepared from PET (Polyethylene Terephthalate), EPR (Ethylene Propylene Rubber), EPR-g-MAH (Ethylene Propylene Rubber-g-MAH), PE-g-MAH, TPEE (Thermoplastic Polyether Ether The inner surface layer is composed of PET, PP, EPDM-g-GMA, butyl acrylate, methyl methacrylate and zinc stearate. The toughening effect can be achieved, the thermal deformation temperature and impact strength of the film can be improved, and the antistatic function and multiple functions are achieved.

Description

Technical field [0001] The invention relates to the technical field of BOPET films, specifically a method for producing a multifunctional MLCC release film base film. Background technique [0002] Chip multilayer ceramic capacitors (Multi-layer Ceramic Capacitors in English, abbreviated as MLCC) are made of ceramic dielectric diaphragms with printed electrodes (internal electrodes) stacked in a staggered manner, and then formed into ceramic chips through one-time high-temperature sintering. A metal layer (external electrode) is sealed on both ends of the chip to form a monolithic-like structure, so it is also called a monolithic capacitor. The MLCC manufacturing process uses polyester film as the base film. First, a silicone coating is coated on the surface of the base film to prepare a release film. Then, liquid clay (i.e., ceramic slurry) is evenly coated on the silicone of the release film. The coating surface is then printed with electrodes on the clay layer, and then t...
