Abstract

The invention relates to the field of functional master batches, and discloses a functional master batch for improving polyethylene packaging film toughness. The functional master batch is prepared from the following components in parts by weight: 80-100 parts of carrier resin, 20-25 parts of toughener, 10-15 parts of low-density polypropylene resin, 1-2 parts of curing agent, 0.6-1.0 part of oxidized polyethylene wax, 0.6-0.8 part of white carbon black, 0.5-0.8 part of antioxidant 1076 and 0.5-1.0 part of coupling agent. The carrier resin is a polyethylene resin; and the toughener is composed of milk fibers, corn fibers and graphene. Under the synergic actions of the characteristics of stretching resistance, high strength and scratch resistance of the milk fibers, corn fibers, low-density polypropylene and the like, the functional master batch improves the stretching toughness and puncture resistance of the polyethylene packaging film product, enhances the aging resistance and mold resistance of the polyethylene packaging film product and prolongs the service life of the polyethylene packaging film.

Description

technical field [0001] The invention relates to the field of functional master batches, in particular to a functional master batch for improving the toughness of polyethylene packaging films. Background technique [0002] Polyethylene (PE) is a kind of thermoplastic resin prepared by ethylene polymerization. It has excellent electrical insulation performance, chemical stability, low water absorption and can withstand most acid and alkali corrosion. Therefore, it is one of the preferred materials for making packaging films, especially It is the outer packaging film for the whole beer, canned beverage, and bottled beverage. This kind of packaging film is not easy to be damaged, not afraid of moisture, and is very convenient to use. However, this kind of packaging film has low tensile toughness and unstable puncture resistance. It is prone to permanent deformation and often breaks the package when pulled by an external force, which leads to a short service life. Chinese patent...
