Embodiment Construction

[0043] In order to understand the technical solution of the present invention more intuitively and completely, the non-restrictive feature description is as follows:

[0044] A method for producing a multifunctional MLCC release film base film, characterized in that: the base film includes an outer layer, a middle core layer and an inner surface layer;

[0045] The outer layer is composed of PET, ABS, PC, antioxidant 1010, PE-g-MAH, PBT, glass fiber, and talcum powder;

[0046] The middle core layer is composed of PET, EPR, EPR-g-MAH, PE-g-MAH, TPEE, GMA-St-AN, antioxidant 1010;

[0047] The inner surface layer is composed of PET, PP, EPDM-g-GMA, butyl acrylate, methyl methacrylate, zinc stearate;

[0048] The production method comprises the following steps:

[0049] (1) take raw material respectively according to each component ratio of outer layer, middle core layer and inner surface layer;

[0050] (2) The raw materials of the outer surface layer, the middle core layer a...

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, in particular to a production method of a multifunctional MLCC release film base film. Background technique [0002] Chip multilayer ceramic capacitors (Multi-layer Ceramic Capacitors, abbreviated as MLCC) are laminated by ceramic dielectric diaphragms with printed electrodes (internal electrodes) in a dislocation manner, and form ceramic chips after one-time high-temperature sintering. The metal layer (external electrode) is sealed at both ends of the chip to form a monolithic structure, so it is also called a monolithic capacitor. The MLCC manufacturing process uses polyester film as the base film, first coats the silicone coating on the surface of the base film to prepare a release film, and then evenly coats the liquid clay (that is, ceramic slurry) on the silicone of the release film. On the surface of the coating, electrodes are printed on the clay layer, and then the clay layers print...
