Embodiment 1

[0025] A preparation method for a novel PET strap masterbatch, comprising the following steps:

[0026] (1) Wash the fly ash floating beads with water, add a hydrofluoric acid solution with a concentration of 0.5mol / L and stir for 8 minutes, the weight ratio of the fly ash floating beads to the hydrofluoric acid solution is 1:25, and suction filter Finally, wash with water for 5 times, place the temperature in an oven at 140°C and dry for 3 hours to obtain acidified fly ash floating beads;

[0027] (2) adding the acidified fly ash bleaching beads that step (1) obtains into the aqueous solution of 5% cetyltrimethylammonium chloride, the acidifying fly ash bleaching beads and cetyl trimethylammonium The weight ratio of the aqueous ammonium chloride solution is 1:36. After ultrasonic stirring for 2 hours, let it stand for 2 hours. The acidified fly ash floating beads suspended in the upper layer and the acidified fly ash floating beads precipitated at the bottom are poured into t...

Abstract

The invention provides a preparation method of a novel PET packing belt masterbatch. The method comprises the following steps: (1) cleaning fly ash floating beads, adding a hydrofluoric acid solution and stirring, performing suction filtration and washing with water, and drying in an oven to obtain acidified fly ash floating beads; (2) adding the acidified fly ash floating beads into an aqueous solution of cetyltrimethylammonium chloride, performing ultrasonic stirring and standing, pouring into a filter screen for filtering, washing the filter residue with water, and drying in the oven to obtain modified fly ash floating beads; (3) adding bismuth oxychloride into water and stirring to obtain a suspension, adding the suspension into an aqueous solution of a PAMAM half-generation dendrimer polymer and performing magnetic stirring, discharging and then filtering, washing the filter residue with absolute ethyl alcohol, and drying in the oven to obtain modified bismuth oxychloride; and (4) drying the PET granules and then stirring in a stirrer, adding the modified fly ash floating beads and modified bismuth oxychloride, and stirring continuously to obtain the PET packing belt masterbatch. By adopting the method provided by the invention, the prepared packing belt masterbatch has relatively good aging resistance and can adapt to severe environment.

Description

Technical field: [0001] The invention relates to a packaging material, in particular to a preparation method of a PET packing tape masterbatch. Background technique: [0002] PET packing belt is a kind of polyester packing belt formed by extruding and unidirectionally stretching PET as the main raw material. It is currently the most popular new environmentally friendly packaging material in the world to replace steel belt, steel wire, and heavy-duty PP packing belt. It has many advantages. Advantages: (1) Strong tensile strength, not only the tensile strength of steel belt, but also the ductility of impact resistance, which can ensure the safety of product transportation; (2) The elongation is small, and the elongation is only the poly One-sixth of the acrylic belt, which can maintain the tension for a long time; (3) good safety, without the disadvantages of steel belt rusting and pollution of the bundled objects, and the color is bright; (4) good economic benefits, 1 ton of...
