Tension-resistant plastic woven bag and production method thereof

Abstract

The invention discloses a tension-resistant plastic woven bag. The tension-resistant plastic woven bag is characterized in that polypropylene is used as the base material, master batch raw material varieties and formula are optimized, a production process is improved, and modified carbon nanotubes, Prunus Humilis Bunge fibers, polyethylene / winter rye peptide compounds and bitter almond oil are scientifically compounded to produce the tension-resistant plastic woven bag; the modified carbon nanotubes can evidently increase the tension resistance, relative tension load, strength, toughness and elasticity modulus of the plastic woven bag; the Prunus Humilis Bunge fibers can evidently increase the impact resistance of the plastic woven bag and are easy to biologically degrade and capable of lowering production cost; the polyethylene / winter rye peptide compounds can greatly increase the low temperature resistance of the plastic woven bag; the bitter almond oil can effectively increase the lubricating performance and oxidation resistance of the plastic woven bag. The produced tension-resistant plastic woven bag has the advantages that the tension-resistant plastic woven bag is excellent in physical property, to be more specific, the plastic woven bag is high in tension resistance load, the multi-directional tension load of the plastic woven bag is 520-930(N / 50mm), and the release force of the plastic woven bag is 6.5(N / 30mm); the plastic woven bag is high in impact resistance, to be more specific, bag breaking in optional directions is avoided when the plastic woven bag falls from a position 2m in height; the plastic woven bag is high in ultraviolet resistance, to be more specific, the multi-directional tension load retention rate of the plastic woven bag is 78-85% after the plastic woven bag is subjected to ultraviolet irradiation alternate experiments for 144 hours.

Description

technical field [0001] The invention relates to a plastic woven bag, in particular to a stretch-resistant plastic woven bag and a preparation method thereof. Background technique [0002] Plastic woven bags are made of polypropylene (PP) and polyethylene (PE) resins as the main raw materials, adding a small amount of auxiliary materials, mixing them and melting them through an extruder, extruding plastic films and cutting them into filaments, which are processed at a temperature lower than the melting temperature of the resins Stretching, making high-strength, low-elongation flat yarn through molecular orientation and heat setting, and then winding, weaving, cutting, and sewing to make plastic woven bags. Plastic woven bags are divided into TA type, A type, B type and C type according to the loading quality range, TA type is allowed to load 10~20kg, A type is allowed to load 21~30kg, B type is allowed to load 31~50kg , Type C is allowed to load 51 ~ 60kg. Plastic woven bag...
