Packaging material for electronic product and preparation method of packaging material

Abstract

The invention belongs to the field of packaging materials, and discloses a packaging material for an electronic product and a preparation method of the packaging material. The preparation method comprises the following steps that 1, polyvinyl chloride, polyethylene glycol terephthalate, Polyethylene glycol 200 diacrylate, fluorinated ethylene-propylene, octenyl succinic acid modified starch, styrene-butadiene rubber, polyarylether, poly(vinyl alcohol)phthalate and polyethylene glycol succinate are taken by weight and are stirred; 2, the material stirred in the step 1 is extruded through a double-screw extruder, and pelleting is carried out after extruding; 3, the pelleted material is rolled and molded, and after cooling, the material is prepared into the packaging material for the electronic product. The prepared packaging material has very good tearing strength and elongation at break, and has very good prospects when used for sealing, dust prevention and dampness prevention of the electronic product.

Description

technical field

[0001] The invention belongs to the field of packaging, and relates to a packaging material for electronic products and a preparation method thereof. Background technique

[0002] Packaging materials refer to the materials used to make packaging containers, packaging decoration, packaging printing, packaging and transportation to meet product packaging requirements, including metal, plastic, glass, ceramics, paper, bamboo, wild mushrooms, natural fibers, Main packaging materials such as chemical fibers and composite materials, and auxiliary materials such as coatings, adhesives, strapping tapes, decorations, and printing materials. Polyvinyl chloride is widely used. In terms of packaging materials, it can manufacture packaging films, shrink films, composite films and transparent sheets, as well as containers and turnover boxes, as well as packaging coatings. When used in the packaging of electronic products, the requirements for the ductility and tear resis...
