Abstract

The invention discloses an anti-fouling polypropylene film. The film is prepared from components in parts by weight as follows: 80-100 parts of polypropylene master batch, 10-15 parts of polyvinyl butyral, 8-12 parts of a metallocene ethylene-ethylene copolymer, 5-9 parts of modified chitosan, 0.3-1.5 parts of nano-silver, 1-4 parts of chitin fibers, 1-3 parts of allicin, 0.4-1 part of a coupling agent, 2-5 parts of a slipping agent, 1-3 parts of nano-titania, 1-2 parts of nano tin antimony oxide powder, 0.5-1.5 parts of organic montmorillonite, 0.5-1.5 parts of an antioxidant, 2-5 parts of glass beads, 1-2 parts of a toughening agent and 1-2 parts of a reinforcing agent. The polypropylene is taken as a main material, added polyvinyl butyral, metallocene ethylene-ethylene copolymer and modified chitosan have a synergistic effect, the hydrophic property of the polypropylene film can be enhanced obviously, the wetting angle is obviously reduced, the film forming property of the system is improved, the cellular structure of the film is improved, and the moisture penetrability of the film is improved; nano-silver, chitin fibers and allicin are added to the system, and the film has a bacteriostasis function.

Description

technical field [0001] The invention relates to the technical field of plastic film production, in particular to an antifouling 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...
