The present invention relates to a method for preparing a linear low density polyethylene composite and a linear low density polyethylene composite according to the present invention. It relates to a method for producing a polyethylene composite and a linear low density polyethylene composite prepared accordingly.

Linear low density polyethylene is a type of polyethylene with a number of short side chains. Generally, a transition metal catalyst with an alpha-olefin comonomer (butene, pentene, hexene, octene, etc.) having side chains of ethylene monomers, In particular, they are prepared by copolymerization using Ziegler-Natta or Philips catalysts.

The linearity of the linear low density polyethylene molecular chain is derived from the manufacturing process difference between linear low density polyethylene and low density polyethylene. Generally, linear low density polyethylene is prepared by copolymerizing ethylene and alpha-olefins (butene, pentene, hexene, octene, etc.) at low temperature and low pressure.

The linear low density polyethylene thus prepared is less sensitive to shear and has very different rheological properties because it has a narrower molecular weight distribution and shorter side branches than the conventional low density polyethylene. Linear low density polyethylene is used in various applications such as pipes, containers, covers, toys, plastic bags, baskets, wire coatings, membranes, etc., because it can be molded into plastics, sheets, and films through shearing processes such as melt extrusion.

Hereinafter, a method for producing a linear low density polyethylene composite according to the present invention will be described.

To this end, a method of manufacturing graphene applied to the present invention will be described first.

Here, in the method for producing graphene, first, carbon nanoparticles mixed with graphene and carbon nanotubes and linear low density polyethylene homopolymers are combined, but the carbon nanoparticles and linear low density polyethylene homopolymers are 0.001 to 99.999: 99.999 to 0.001 It is preferable to prepare a variety of combinations in the range of weight% of, more preferably the carbon nanoparticles are prepared in combination in the range of 0.01 to 50.00% by weight relative to the total weight of the composite.

Examples 1-7 and Comparative Example 1

Linear low density polyethylene polymer for the present invention was used as Hanwha Chemical Co., Ltd. product. As one of the carbon nanoparticles, graphene was directly prepared by acid treatment and thermal expansion (1050, 30 seconds) using natural graphite purchased from Sigma Aldrich Co., Ltd.

As carbon nanotubes, Hanwha Nanotech's multi-walled carbon nanotubes (model name: CM-250) were used, and products having a diameter of 10 to 15 nm were used.

The weight ratio of LLDPE polymer and mixed carbon nanoparticles (graphene + multiwall carbon nanotubes) in melt mixing was 98.0: 2.0, and the relative weight ratio of graphene and multiwall carbon nanotubes in mixed carbon nanoparticles was [ Table 1 was adjusted in various ways. Melt mixing was performed using a Bautech twin screw melt extruder, the temperature was adjusted to 160 to 170 ℃.

Experimental Example 1 (Electrical Resistance Measurement)

An electrical resistance meter (Keithley 8009 resistivity test fixture, Keithley 2400 sourcemeter / 2181 nanovoltmeter) was used to measure the electrical conductivity of the linear low density polyethylene composite.

In Comparative Example 1, the linear low density polyethylene homopolymer showed a volume electrical resistance value of ˜10 16 Pa · cm.

1 is a view showing the volume electrical resistance of a linear low density polyethylene composite according to the present invention, the volume of the linear low density polyethylene composite in which 2.0 wt% of carbon nanoparticles mixed with graphene and multi-walled carbon nanotubes of various weight ratios are introduced. It is a figure which shows electric resistance.

As shown in the figure, the linear low-density polyethylene composite of the mixed carbon nanoparticles (graphene + multi-walled carbon nanotubes) results from the change in the volumetric electrical resistance value of the composite according to the weight ratio change of the multi-walled carbon nanotubes It can be seen that the electrical conductivity can be easily controlled according to the composition ratio change of the mixed carbon nanoparticles.

For example, as shown in Examples 1 and 2, when the weight ratio of graphene to multi-walled carbon nanotubes is 100: 0 or 90:10, the volume electrical resistance of the linear low density polyethylene composite is ˜10 16 Pa · cm On the other hand, as shown in Example 3, when the weight ratio of graphene to multi-walled carbon nanotubes is 70:30, the volume electrical resistance of the linear low density polyethylene carbon nanotube composite is ~ 10 12 Pa.cm As shown in Example 4, when the weight ratio of graphene to multi-walled carbon nanotubes is 50:50, the volume electrical resistance of the linear low density polyethylene carbon nanotube composite is -10 8 Pa · cm. In addition, when the weight ratio of graphene: multi-walled carbon nanotubes is 30:70, 10:90, and 0: 100, respectively, as in Examples 5, 6, and 7, the volume electrical resistance of the linear low density polyethylene composite is ˜10 6 kPa. It can be seen that the volume electric resistance drops rapidly, such as in cm.

From this, it can be seen that as the content of the multi-walled carbon nanotubes in the mixed carbon nanoparticles (graphene + multi-walled carbon nanotubes) increases, the volumetric electrical resistance of the composite is continuously lowered.

The linear low density polyethylene composite prepared according to the method for producing a linear low density polyethylene composite according to the present invention has an electrical resistance significantly lower than that of a conventional linear low density polyethylene single polymer as demonstrated in the above experimental example. Therefore, it can be usefully applied in the form of film, fiber, plastic, and the like in various fields where antistatic and electromagnetic shielding functions are required.

While the invention has been shown and described in connection with particular embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention as set forth in the appended claims. Anyone can easily know.
