Embodiment 1

[0023] The antistatic woven bag, its raw materials are calculated by weight percentage, and consists of the following components: 2% dispersant, 1.5% crosslinking agent, 0.8% coupling agent, 0.8% nano calcium carbonate, 1% antioxidant, linear low density polyethylene Ethylene 9%, antistatic agent 4.0%, the balance is polypropylene. The dispersant is The crosslinking agent is TAC, the coupling agent is borate, the antioxidant is 1010 antioxidant, and the antistatic agent is J3200.

[0024] The preparation method of above-mentioned antistatic woven bag is as follows:

[0025] 1. Put the raw materials in the above ratio into the mixing tank and stir them evenly, then use the suction feeding system to suck them into the extruder. It is plasticized into a molten state under shearing, and then extruded into a film through the die head of the extruder; when extruding into a film, the pulling-out speed is controlled to be 5 times the extrusion pulling-off speed of the film mouth, a...

Abstract

The invention discloses an anti-static woven bag and a manufacturing method thereof. The anti-static woven bag comprises, by weight, 2-3.5% of dispersing agent, 1.5-3% of cross-linking agent, 0.8-1.5% of coupling agent, 0.8-2.0% of nano calcium carbonate, 1-2% of antioxidant, 9-11% of linear low density polyethylene, 2.0-4.0% of anti-static agent and the balance polypropylene. According to the anti-static woven bag and the manufacturing method of the anti-static woven bag, due to the fact that the 2-4% of anti-static agent is added in ingredients of the woven bag, the surface of the woven bag can have lubricity, the friction coefficient of the woven bag is obviously lowered, meanwhile, static charges generated on the surface of the woven bag are restrained and reduced, and thus the woven bag has the excellent anti-static performance. In addition, in the process of manufacturing the anti-static woven bag, the anti-static performance of the woven bag can be effectively achieved by adjusting the specific parameters of drawing, weaving and other links, and the anti-static effect of the woven bag is finally achieved.

Description

technical field [0001] The invention belongs to the field of packaging, and in particular relates to an antistatic woven bag and a preparation method thereof. Background technique [0002] Bags made of polypropylene plastic have the advantages of light weight, high strength, and low cost. Therefore, in real life, polyester chips, polyester staple fibers and other chemical products are packaged in polypropylene plastic woven bags. However, since polypropylene is a resin with high volume resistivity, it is easy to generate static electricity and cause serious dust absorption. When the static electricity is serious, it may even cause damage to the internal chips of the electronic products in the bag. Therefore, anti-static woven bags came into being. However, the actual anti-static stability of many anti-static woven bags is poor, and it cannot really achieve the purpose of anti-static. Contents of the invention [0003] In view of this, the object of the present invention...
