Embodiment 1
[0045] Embodiment 1 raw material preparation
[0046] 1. Preparation of calcium fruit fiber:
[0047]The preparation method of the said calcium fruit fiber comprises the following steps: uniformly mixing fresh calcium fruit stems, calcium fruit leaves and waste sawdust according to the mass ratio of 5:4:1.5, placing them in an ultrasonic cleaning machine at 200W and 30KHz for cleaning for 4 minutes, draining Dry, crush, add water with 1 times the weight of the crushed material, ultrasonically extract at room temperature 300W, 35KHz for 12min, and then perform high-voltage pulse electric field treatment for 12min under the conditions of electric field strength 30kV / cm, pulse time 500μs, and pulse frequency 300Hz; adjust the pH value 8. Add biological enzyme with 0.2% mass of the mixture, and enzymatically hydrolyze at 55°C for 12 minutes; the enzymolyzed solution is concentrated under reduced pressure to a solid content of 50%, and placed in a microwave dryer at 2000W and 140°C...

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...
