Problems solved by technology

The static electricity generated by the PE material during the processing brings a lot of inconvenience to the further processing of the packaging film material, affects the operation performance of the product, and the printing effect is affected by the electrostatic interference when the film is used for packaging, and it is difficult to make it into a bag. Separated or sealed, it will cause electric shock in severe cases

[0049] The dispersibility experiment is detected by the following method: 10 mg of activated carbon nanotubes prepared in Examples 1 to 16 are added to 10 mL of the solvent (see Table 1) used to prepare the activated carbon nanotubes, and ultrasonically dispersed for 30 minutes to obtain a suspension solution, stand still, and when obvious stratification occurs, the recorded time is the storage time, and the results a...

Embodiment 17～32

[0052] The activated carbon nanotubes prepared in Examples 1 to 16 and the PE polymer powder material (average particle diameter 100 μm to 2 mm) were stirred and mixed, and then mixed with auxiliary agents. The dosage of each raw material was shown in Table 3 and Table 4. The PE / carbon nanotube conductive masterbatch is obtained by melt extrusion, stretching, cooling and granulation of the screw extruder; the processing technology of the twin-screw extruder is that the screw speed is 200r / min, and the extrusion temperature is 180°C.

[0053] The carbon nanotube content of the prepared PE / carbon nanotube conductive masterbatch is shown in Table 5.

[0054] The prepared PE / carbon nanotube conductive masterbatch was blown by a blow molding machine to obtain an antistatic film, and the surface resistivity of the film was tested according to "GB / T1410-2006 Test Method for Volume Resistivity and Surface Resistivity of Solid Insulating Materials". And detect its physical properties, ...

Abstract

The invention discloses an active carbon nanotube modified polyethylene antistatic thin film. The active carbon nanotube modified polyethylene antistatic thin film is prepared from the following components in parts by mass: 70 to 95 parts of a PE (Polyethylene) polymer matrix material, 0.01 to 10 parts of active carbon nanotubes and 0.1 to 20 parts of an auxiliary agent; the auxiliary agent is formed by mixing one or more than two of a dispersant B, a coupling agent, an antioxidant, a lubricant and an anti-abrasion agent; the active carbon nanotubes are prepared by dissolving a dispersant A into a solvent to obtain a dispersant solution, spraying the dispersant solution into carbon nanotubes stirred at a high speed through a high-pressure spraying method and stirring and mixing at a high speed. The polyethylene antistatic thin film disclosed by the invention is good in conductive property, high in antistatic durability and long in service life.

Description

1. Technical field [0001] The invention relates to an active carbon nanotube modified polyethylene antistatic film. 2. Background technology [0002] Polyethylene (PE) is widely used because of its rich raw material resources, moderate price, stable and reliable production process, and superior product comprehensive performance, especially in the packaging field, because its price-performance ratio is superior to other packaging materials. It occupies the first place in general-purpose plastic packaging materials. With the in-depth development of my country's modernization, various plastic packaging materials emerge in an endless stream, and their demand is also increasing. Among them, PE packaging film accounts for more than 30% of the total consumption of PE materials. More than one million tons of PE materials are consumed every year. However, due to the non-polar molecular structure of polyethylene materials, the molecular chains formed by its covalent bonds can neith...
