Problems solved by technology

[0003] It is understood that the plastic bags we can see in the market are ordinary conventional plastic bags. Even if there are some anti-static bags, because of some characteristics of anti-static masterbatch, the anti-static effect of the bags is not obvious.
For example, the anti-static bag is good, but it feels sticky, and sometimes the bag cannot be opened and cannot be used
Some bags are said to be anti-static, but the static resistance value is not up to standard
Nowadays, the conventional plastic bags are made of polyethylene materials, and the anti-static bags basically stay on the top of the anti-static masterbatch, but the effect is not obvious, and the requirements for the test conditions are relatively high. No persuasiveness and standard usability

Abstract

The invention discloses an anti-static polyethylene film material and a preparation method thereof, as well as an anti-static bag. The anti-static polyethylene film material is prepared from the following raw materials in percentage by weight: 60-70 percent of linear low-density polyethylene, 20-30 percent of high-pressure polyethylene, 2-5 percent of low-pressure polyethylene and 3-5 percent of anti-static masterbatches. The preparation method of the anti-static polyethylene film material comprises the following steps: respectively weighing all the components in part by weight; putting all the components in an extruder for extrusion, wherein the temperature of a first zone of the extruder is 145-155 DEG C, the temperature of a second zone is 150-160 DEG C, the temperature of a third zoneis 150-160 DEG C, the temperature of a die head of the extruder is 150-170 DEG C, the rotating speed of a lead screw is 100-120 r / min, and the host frequency is 12-14 HZ; after extrusion, cooling, forming and winding to obtain the anti-static polyethylene film material. As the anti-static masterbatches and the low-pressure polyethylene are added, the anti-static polyethylene film material disclosed by the invention not only has a very good anti-static effect, but also is good in opening performance.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an antistatic polyethylene film material, a preparation method thereof, and an antistatic bag prepared by using the antistatic polyethylene film material. Background technique [0002] With the continuous development of information technology, the demand for electronics is getting bigger and bigger, but with the development of electronic products, it will be found that the electronic components are getting smaller and smaller, the precision is getting higher and higher, and the requirements for the outside world are getting higher and higher, and the cost of good packaging Too high, simple plastic packaging will find that the damage to electronic components is relatively large. So anti-static was born. The electrostatic bag can effectively avoid the interference or even damage of small components by external static electricity. [0003] It is understood th...
