High-strength material prepared from waste polyester bottle flakes and polypropylene film waste and specially used for woven bags and method of material

Abstract

The invention relates to a high-strength material prepared from waste polyester bottle flakes and polypropylene film waste and specially used for woven bags and a method of the material, and belongs to the technical field of waste plastic treatment and resource utilization. The waste polyester bottle flakes (PET) and the polypropylene film waste (PP) are smashed into materials with similar sizes, the materials are cleaned, dried and mixed to be uniform, and PET and PP mixed waste materials are prepared; 100 parts of the prepared PET and PP mixed waste materials are blended with 5-10 parts of chlorinated polyethylene, 0.5-1 part of maleic anhydride, 0.5-1 part of silane coupling agent, 3-5 parts of SBS, 1-3 parts of paraffin oil and 0.5 part of ferrous sulfate to be extruded and pelletized, and the material special for the woven bags is obtained. The tensile strength of the prepared material special for the woven bags exceeds that of a material special for PP-T30S grade drawing-class woven bags; due to the fact that the raw material formula comprises ferrous sulfate which can be combined with odors of the waste polyester bottle flakes and the polypropylene film waste, the odors emitted by waste plastic during processing are effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of treatment and resource utilization of waste plastics, and relates to a high-strength woven bag special material prepared by using waste polyester bottle flakes and polypropylene film waste and a 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 of daily packaging bottles, and polypropylene (PP) 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 object of the present invention is to overcome the shortcoming of prior art, provide a kind of high-strength woven bag special material and its method that utilize waste pol...

Problems solved by technology

[0002] Existing polyester waste bottle flakes (i.e. polyethylene terephthalate, PET) are generally used for weaving or alone for blowing low-end products of daily packaging bottles, and polypropylene (PP) film waste is also used They are all processed into low-end products such as poor-quality woven bags, packing belts, or daily-use packaging by means of separate recycling. This kind of extensive recycling has simple processing, poor quality, and low utilization value.
