Abstract

The invention provides a preparation method of a PET composite for a packaging tape. The preparation method comprises the following steps of (1) sieving after grinding beidellite by using a grinder to obtain beidellite powder, adding the beidellite powder into distilled water and stirring to obtain ore pulp, adding a CTAB water solution after regulating the ph value to 7.5, transferring the water solution to a thermostatic water bath to stir, carrying out suction filtration to obtain a white sediment, washing five times, and drying to obtain modified beidellite powder for later use; (2) dissolving the modified beidellite powder into an organic solvent, adding PET particles after ultrasonically stirring, stirring in a water bath, pouring the material into a vessel with a cover, placing the vessel with the cover into a fuming cupboard, and after the organic solvent is volatilized, transferring the vessel with the cover to a vacuum drying oven to dry for 15 hours to obtain a mixed material; and (3) after drying melamine-formaldehyde resin, placing the melamine-formaldehyde resin and the mixed material into a high-speed mixer to mix for 15 minutes, and transferring the mixture to a double-screw extruder to extrude to obtain the PET composite for the packaging tape. The composite prepared by using the preparation method has relatively good corona resistance and water resistance and can be applied to various occasions.

Description

Technical field: [0001] The invention relates to a packaging material, in particular to a preparation method of a PET composite material used for a packaging tape. Background technique: [0002] PET is the abbreviation of Polyethylene terephthalate in English, and its Chinese meaning is polyethylene terephthalate. The molecular structure of PET is highly symmetrical, and it has certain crystal orientation ability. PET is a milky white or light yellow highly crystalline polymer with a smooth and shiny surface, good creep resistance, fatigue resistance, friction resistance, low wear and high hardness, and has the greatest toughness among thermoplastics; good electrical insulation performance , less affected by temperature, non-toxic, weather resistance, good stability against chemicals, weak acid and organic solvent resistance, so it can be widely used in fiber, film, packaging materials and other fields. [0003] For example, the Chinese patent with the publication number CN...
