Polyethylene (polyethylene, abbreviation PE) is a kind of aggregated thermoplastic resin obtained of ethylene.Industrially,
It also include the copolymer of ethylene and a small amount of alpha-olefin.Polyethylene is odorless, nontoxic, feel ceraceous, has excellent resistance to low temperature
(minimum to use reachable -100 DEG C~-70 DEG C of temperature), chemical stability is good, is resistant to the erosion of most of soda acids (intolerant to oxygen
Change the acid of property).Common solvent is not dissolved under room temperature, water imbibition is small, and electrical insulating property is excellent, therefore is widely used at present each
In each industry of row, polyethylene film is the most widely used high molecular material in the world today, be widely used in medicine, chemical industry,
The industries such as food, electronics, printing, but polyethylene film also has the deficiency of some application aspects, if the heatproof of polyethylene is not capable high,
Existing market
On the polyethylene film that uses generally use temperature to be no more than 100 DEG C, therefore the polyethylene film in some special dimensions
It will be restricted, while under prolonged illumination condition, phenomena such as polyethylene film surface will appear discoloration, film aging adds
Fastly, thus service life is affected, these aspects all greatly limit the application of polyethylene film.
Polyethylene film is safe and non-toxic, permeable, breathe freely moderate, and packaged product can be made in production and processing, transport, stored
It is not contaminated in journey, it is packed suitable for food fresh keeping.But when being applied to the packaging of the food containing grease type, therein one
A little small molecule processing aids (such as flexibility agent) can migrate, and cause food safety hazards.In addition, single PE film does not have
Antibacterial and oxidation resistant functionality.Continuous enhancing with people to health and environmental consciousness, it is frequent to being contacted in daily life
Dish bowl, the various plastics such as household electrical appliances propose the demand of " antibacterial, sterilization ", therefore providing polyethylene antibiotic film is current city
The demand of field.
Summary of the invention
It is an object of that present invention to provide a kind of high temperature resistants, strong, ageing-resistant, excellent in mechanical performance the polyethylene film of antimicrobial form

2 parts, 3 parts of montmorillonite.
Further, lignocellulose sodium and poly- aminopropyltriethoxy sesquialter of the coupling agent by mass ratio for 2-3:1
Siloxanes composition.
Further, the complex antimicrobials are that lanthana and titanium dioxide form by mass ratio 1:1-3.
Further, the processing aid is grafted by the castor oil polyoxyethylene ether and maleic anhydride that mass ratio is 1:2-4
PE wax composition.
Further, the antioxidant be one of CA antioxidant, 1010 antioxidants and 1076 antioxidants or
Numerous compositions.
The preparation method of polyethylene film of the present invention with antibacterial degradable function, includes the following steps:
(1) phytic acid and octaphenyl cage type sesquialter silicon are added in PE, polyisobutene, conch meal, nanometer calcium carbonate, graphene
Oxygen alkane, stirring 20-30min progress surface is modified at being 80-100 DEG C in temperature, obtains modified mixture；
(2) modified mixture, coupling agent, processing aid, complex antimicrobials and antioxidant are added into high kneading machine, In
It is kneaded 10-20min at 80-100 DEG C, obtains mixed material；
(3) after mixed material being delivered to conical double screw extruder extruding pelletization, then with plastic film blowing machine squeeze out blown film,
Obtain polyethylene film.
Further, the temperature of the extruding pelletization is 200-220 DEG C, screw speed 300-500rpm.
Further, the temperature for squeezing out blown film is 200-220 DEG C, screw speed 20-30rpm, and hauling speed is
