Special toughening function regulator for polyethylene filler flat filament

Abstract

The invention relates to a special toughening function regulator for a polyethylene filler flat filament, a special woven bag material prepared by adopting the special toughening function regulator and a preparation method of the special woven bag material, belonging to the technical field of treatment and resource utilization of waste plastic. The preparation method of the special woven bag material comprises the following steps of firstly, crushing waste polyester (PET) bottle flakes and polyethylene (PE) film wastes into materials with similar sizes, cleaning, drying and then uniformly mixing to obtain PET / PE mixed wastes; secondly, taking 100 parts of prepared PET / PE mixed wastes to be blended with 5 to 10 parts of chlorinated polyethylene, 0.5 to 1 part of maleic anhydride, 0.5 to 1 part of silane coupling agent, 3 to 5 parts of SBS (Styrene Butadiene Styrene Block Copolymer), 1 to 3 parts of liquid paraffin and 0.5 part of ferrous sulfate, extruding and granulating to obtain the special woven bag material. The tensile strength of the special woven bag material prepared by the preparation method disclosed by the invention exceeds that of a PP-T30S grade special woven bag material; in addition, a raw material formula contains the ferrous sulfate, and the ferrous sulfate can be odorously and chemically synthesized with the waste polyester bottle flakes and the polyethylene film wastes, so that odor given off by the waste plastic in the processing process can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of treatment and resource utilization of waste plastics, and in particular relates to a special toughening function regulator for polyethylene filler flat yarn, and a special material for woven bags prepared by using the regulator and a preparation method thereof. Background technique [0002] Existing polyester waste bottle flakes (i.e. polyethylene terephthalate, PET) are generally used for weaving or alone for blowing low-end products such as daily packaging bottles, and polyethylene (PE) film waste is also used They are all processed into low-end products such as poor-quality woven bags, packing belts, or daily packaging by means of separate recycling. This kind of extensive recycling has simple processing, poor quality, and low utilization value. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcoming of prior art, provide the special toughening functiona...
