The invention discloses a production method of a high-temperature-resistant high-barrier polypropylene film, which takes isotactic polypropylene-b-polyethylene glycol two-block substances as a compatilizer of isotactic polypropylene and polyvinyl alcohol, the polyvinyl alcohol has excellent oxygen resistance, and after the isotactic polypropylene-b-polyethylene glycol two-block substances are taken as the compatilizer, the isotactic polypropylene and the polyvinyl alcohol have good compatibility, so that a polyvinyl alcohol phase can be uniformly dispersed in polypropylene resin to form a secondary continuous phase or lamellar structure, thereby obviously improving the barrier property of a blended film, adding nano silicon dioxide to improve the hardness of the film, further improving the energy of thermal deformation resistance, and adding palm wax to effectively improve the tearing effect. |
