High-crystallized polypropylene microporous membrane

Abstract

A high-crystallized polypropylene microporous membrane belongs to the technical field of chemical engineering, comprises the following components by mass percent: 30% of high-crystallized polypropylene polymer, 30% of polylactic acid, 30% of polyvinyl, and 10% of high-crystallized biodegradable polymer, and has the advantages that properties of high crystallinity and high density are achieved.

Description

Technical field: [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a high crystallization polypropylene microporous film. Background technique: [0002] At present, there are many kinds of thin films on the market, but none of them are made of high crystallinity. Invention content: [0003] Aiming at the deficiencies of the prior art, the invention provides a high crystallization polypropylene microporous film. [0004] The film is composed of 30% of high crystallinity polypropylene polymer, 30% of polylactic acid, 30% of polyethylene and 10% of high crystallinity biodegradable polymer by mass percentage. [0005] The invention has the advantages of high crystallization and high density. detailed description: [0006] The present invention is described in conjunction with specific embodiments. [0007] The film is composed of 30% of high crystallinity polypropylene polymer, 30% of polylactic acid, 30% of polyethylen...
