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. Specific steps are as follows:
[0068] Add ethylene, alpha olefin, hydrogen and nitrogen into the fluidized bed gas phase reactor, then add the catalyst system, and then polymerize under the conditions of temperature 84-88°C and pressure 1.8-2.0MPa to obtain components A, Component B and Component C. Among them, the control of the melt index of component A, component B and component C is realized by adjusting the amount o...
