The invention discloses a high-smooth polyamide master batch, a polyamide film and a preparation method thereof. The high-smooth polyamide film is sequentially provided with an upper surface layer, a core layer and a lower surface layer from top to bottom; the upper surface layer and the The lower layer includes 3-6 parts of high-smooth polyamide master batch and 94-97 parts of polyamide resin by mass parts; the core layer is composed of polyamide resin; wherein, the high-slip polyamide master batch is by mass parts It includes 0.5-10 parts of surface-modified silicon microspheres, 0-10 parts of opening agent, and 80-99.5 parts of polyamide resin; the silicon microspheres are silane cross-linked particles containing methacryloyloxy groups. The polyamide masterbatch and the film of the invention have a low friction coefficient, overcome the problem of easy migration of common slip agents, expand the application field of the polyamide film, and have broad application prospects. |
