Abstract

The invention discloses a modified polypropylene film, made from, by weight, 80-100 parts of polypropylene masterbatch, 8-12 parts of metallocene ethylene-hexene copolymer, 3-6 parts of maleic anhydride grafted polypropylene, 0.1-0.5 part of polyvinyl methyl ether, 1-3 parts of polystyrenesulfonate, 0.3-1.5 parts of a defoaming agent, 0.4-1 parts of a coupling agent, 2-5 parts of a slipping agent, 1-3 parts of nano titanium dioxide, 1-2 parts of nano tin antimony oxide powder, 0.5-1.5 parts of organic montmorillonite, 1-1.5 parts of a dispersant, 0.5-1.5 parts of an antioxidant, 2-5 parts of glass beads, 1-2 parts of a toughener, and 1-2 parts of graphene. The metallocene ethylene-hexene copolymer, the maleic anhydride grafted polypropylene, the polyvinyl methyl ether and polystyrenesulfonate are added to polypropylene as a main material to carry out modification, gas barrier property, hydrophilicity, stain resistance, toughness and impact resistance of the film are improved, and the film also has good properties of static resistance, antibacterial property, weatherability, stability, thermal insulation, ultraviolet resistance, self-cleaning resistance and aging resistance.

Description

technical field [0001] The invention relates to the technical field of plastic film production, in particular to a modified polypropylene film. Background technique [0002] With the continuous development of industry, polymer materials are widely used, and the requirements for material performance in various fields are constantly improving. In order to meet the needs of the application, the materials made of pure resin are insufficient. Therefore, the field of polymer materials must be innovated, and the research on plastic modification is becoming more and more important. Good toughness, high strength, good performance and low price, etc. A single homopolymer material is often difficult to meet the above requirements, so the existing polymer materials can be modified by nanocomposite technology, and new polymer materials with excellent comprehensive properties can be made, which has become an important research direction in the field of new material development , has bro...
