Embodiment approach

[0037]According to a preferred embodiment of the present invention, the antibacterial composition is prepared in a multi-reactor parallel device as shown in Figure 1, and the multi-reactor parallel device includes a first reactor 1 and a second reactor 2 , the third reactor 3, solid / liquid (gas) separator 4, homogenizing silo 5 and melting granulation system 6, wherein, the first reactor 1, the second reactor 2 and the third reactor 3 Connected in parallel, the number of the solid / liquid (gas) separator 4 is three, communicated with the first reactor 1, the second reactor 2 and the third reactor 3 respectively, prepared by the first reactor 1 Component A, the component B prepared by the second reactor 2 and the component C prepared by the third reactor 3 carry out phase separation in different solid / liquid (gas) separators 4 respectively, and then the phase The separated component A, component B and component C are transported to the homogenizing silo 5 in proportion and mixed...

Embodiment 1

[0052] This embodiment is used to illustrate the antibacterial composition and film thereof provided by the present invention.

[0053] (1) Preparation of antibacterial composition:

[0054] The polyethylene composition that this embodiment provides is made up of component A, component B and component C, and these three kinds of components are the linear low density polyethylene (LLDPE) of ethylene / alpha olefin copolymerization, wherein, component A And component B adopts Ziegler-Natta catalyst to prepare (the Ziegler-Natta catalyst system is the Ziegler-Natta catalyst system prepared by CN101838351A embodiment 1, the same below), component C It is prepared by using a metallocene catalyst (the metallocene catalyst system is the supported metallocene catalyst prepared in Example 1 of CN102453124A, the same below). Specific steps are as follows:

[0055] Add ethylene, α-olefin, hydrogen and nitrogen (ethylene, α-olefin, hydrogen and nitrogen are of polymerization grade, used a...

Embodiment 2

[0065] This embodiment is used to illustrate the antibacterial composition and film thereof provided by the present invention.

[0066] (1) Preparation of antibacterial composition:

[0067] The polyethylene composition that this embodiment provides is made up of component A, component B and component C, and these three kinds of components are the linear low density polyethylene (LLDPE) of ethylene / alpha olefin copolymerization, wherein, component A And component B is prepared by Ziegler-Natta catalyst, and component C is prepared by metallocene catalyst.

Abstract

The invention relates to an antibacterial composition. The antibacterial composition contains a polyethylene composition and an antibacterial agent, wherein the polyethylene composition contains a component A, a component C and an optional component B; the component A is linear low-density polyethylene copolymerized with ethylene/alpha olefins, and the melt index MIA is 0.01-3.5 g/10 min; the component B is linear low-density polyethylene copolymerized with ethylene/alpha olefins, and the melt index MIB is 3.6-14.9 g/10 min; the component C is linear low-density polyethylene copolymerized with ethylene/alpha olefins, and the melt index MIC is 15-150 g/l0 min. The invention further provides a thin film; the thin film at least comprises a polyethylene layer formed by the antibacterial composition. The thin film provided by the invention has the advantages of being large in draft ratio and high in film forming rate while obtaining better antibacterial property.

Description

technical field [0001] The invention relates to an antibacterial composition and its film. Background technique [0002] Biaxially Oriented Polyethylene (BOPE) film is a film material formed by a polyethylene (PE) resin with a special molecular structure through a biaxial stretching process. In the forming process of BOPE film, after the film is stretched, the PE macromolecular chain and crystal structure are highly oriented, which significantly improves the tensile strength of the film, reduces the tensile elongation at break, and makes the film Lower haze, higher gloss and better clarity. In addition, compared with polyethylene film products prepared by extrusion blow molding process and extrusion casting process in the prior art, BOPE film has high mechanical strength, good puncture resistance and impact resistance, excellent optical properties, energy saving and environmental protection, etc. Advantage. Therefore, BOPE film can be widely used in packaging bags, heavy ...
