Abstract

The invention discloses an extinction casting PE (polyethylene) film and a preparation method thereof. The extinction casting PE film has a three-layer structure of an inner layer, a middle layer andan outer layer; the PE film comprises the following preparation raw materials: nanometer silicon dioxide, nanometer calcium carbonate, an antioxidant, a light stabilizer, a dispersing agent, a lubricating agent, a tackifier, a slipping agent, a coupling agent, LLDPE, a silicon aluminum molecular sieve, aluminum phosphate, PA, cobalt oxide, scandium oxide, zirconium dioxide and HDPE; and the PE film is prepared by the steps of preparing an inner-layer film-forming material, a middle-layer film-forming material and an out-layer film-forming material by selecting different raw materials, and adding the above three layers of film-forming materials into a co-extrusion casting stretcher to prepare the PE film. The casting PE film prepared by the method has extinction property and has high tensile strength, anti-puncture strength and flame resistance.

Description

technical field [0001] The invention belongs to the field of macromolecule chemistry, and in particular relates to a polyethylene film and a preparation method thereof, more specifically to a matting cast PE film and a preparation method thereof. Background technique [0002] Polyethylene (PE) is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefin. Polyethylene is odorless and non-toxic, has excellent low temperature resistance, good chemical stability, insoluble in common solvents at room temperature, good water absorption, and excellent electrical insulation, so it is widely used in various industries. Polyethylene is divided into high-density polyethylene, medium-density polyethylene and low-density polyethylene according to different densities. PE film, which can withstand most acid and alkali erosion, has the advantages of light weight, non-toxic, moisture-proof, and superior h...
