Abstract

The invention relates to a high-barrier and high-moisture-permeability PP film material as well as a preparation method and application thereof. The high-barrier and high-moisture-permeability PP film material comprises block copolymerized polypropylene resin, an antioxidant, a lubricant and the like. The high-barrier and high-moisture-permeability PP film material provided by the invention has excellent barrier performance and relatively good moisture permeability, and can be used as a protective material for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the technical field of membrane materials, and in particular relates to a PP membrane material with high barrier and high moisture permeability and a preparation method and application thereof. Background technique [0002] Barrier and moisture permeability are the two most critical properties of protective materials, which determine the protective effect and comfort of the prepared protective products. Excellent insulation can achieve better protection against viruses, bacteria and dust; good moisture permeability can realize the timely discharge of gas and sweat, avoiding discomfort such as stuffy heat and humidity when wearing. [0003] Polyolefin film material (such as polypropylene film material) is a widely used film material with good insulation performance, but poor air and moisture permeability. [0004] At present, an existing patent discloses a method for preparing a nano-microporous polymer film material. By formin...
