Abstract

The invention discloses an anti-electrostatic plastic woven bag. The environment-friendly anti-electrostatic plastic woven bag with good physical properties is finally prepared through taking polypropylene as base stock, optimizing the raw material species and formula of master batch, improving a production process, scientifically compounding modified carbon nano-tubes, Prunus humilis fibers, a polyethylene / winter rye peptide complex and bitter almond oil, and enabling the compound to be in synergism with other processing aids, wherein the modified carbon nano-tubes can be used for remarkably improving the anti-electrostatic property, relative tensile load, strength, toughness and elastic modulus of the plastic woven bag, the Prunus humilis fibers can be used for remarkably improving the impact resistance of the plastic woven bag, are easily biodegradable and are reduced in production cost, the polyethylene / winter rye peptide complex can be used for greatly improving the low-temperature resistance of the plastic woven bag, and the bitter almond oil can be used for effectively improving the lubricating property and oxidation resistance of the plastic woven bag. Shown by tests, the arithmetic mean value of surface resistance of the upper and lower faces of the anti-electrostatic plastic woven bag disclosed by the invention is 0.3*10<6> omega to 0.5*10<6> omega, and the anti-electrostatic effect is 3 times that of plastic woven bags in the prior art. Simultaneously, the anti-electrostatic plastic woven bag has good physical properties, falling performance and ultraviolet resistance.

Description

technical field [0001] The invention relates to a plastic woven bag, in particular to an antistatic 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 bags have...
