Technical field
The present invention relates to packaging material fields, and in particular to a kind of packaging bag antibacterial PE films and preparation method thereof.
Background technology
Polyethylene (PE) film is widely used to food, pharmaceutical since it is with good physical and chemical stability
Equal packaging materials.But PE film functions are more single at present, PE film-strengths are relatively low, and barrier property and anti-microbial property are poor, make it
Often internal layer membrane materials'use of the limitation as some composite soft packaging materials, this severely limits the practical applications of PE films.
Invention content
In view of the deficiencies of the prior art, the present invention provides a kind of packaging bag antibacterial PE films and preparation method thereof, assigns PE
The good puncture resistance of film, barrier properties for gases and antibiotic property.
To achieve the above object, the technical solution adopted by the present invention is as follows：
A kind of packaging bag antibacterial PE films and preparation method thereof, which is characterized in that PE films of the invention are by following weight
The raw material composition of part：Linear low density polyethylene 15~35, high density polyethylene (HDPE) 25~45, ultra-high molecular weight polyethylene 5~15,
Maleic anhydride grafted polyethylene 10~20, ethylene-octene copolymer 4~10, nano zine oxide/graphene complex 2~8 change
Property nano silicon dioxide 1~5, magnesium stearate 1~2, antioxidant DTBHQ 0.2~0.8.
Nano zine oxide/the graphene complex is obtained by modified graphene area load nano zine oxide
's.The modified graphene is obtained by poly-dopamine surface modified graphene oxide.The nano zine oxide contains
Amount is the 65~85% of nano zine oxide/graphene complex quality.
The modified manometer silicon dioxide is by organosilicon quaternary ammonium salt modified manometer silicon dioxide.Nano silicon dioxide
Grain size is 30~100nm.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) present invention by introducing ethylene-octene copolymer, graphene and nanometer titanium dioxide simultaneously in polyethylene system
Silicon can be effectively improved the puncture resistance of product.
(2) on the one hand the present invention significantly improves nano silicon dioxide by organic antibacterial agent modified manometer silicon dioxide
Dispersion enhances PE films, meanwhile, by acting synergistically with inorganic antiseptic nano zine oxide, the mechanical performance of material can be improved
And anti-microbial property.
(3) present invention introduces nano zine oxide/graphene complexes, by the hybridism of the two, dispersion of mutually promoting,
The antibacterial action of nano zine oxide is promoted, and utilizes the great graphene sheet layer of specific surface area, is effectively formed three-dimensional barrier screen
Barrier, cut-out gas improve gas barrier property in the transmission of material internal.
(4) preparation is simple by the present invention, can accomplish scale production.
Specific implementation mode
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiment of the present invention, instead of all the embodiments.
Each raw material (parts by weight), extruding pelletization and blow molding are weighed according to the formula of each embodiment of the following table 1, obtains PE
Film.
The parts by weight of raw materials of PE films in 1 each embodiment and comparative example of table

| Linear low density polyethylene | 20 | 25 | 30 | 25 |
| High density polyethylene (HDPE) | 30 | 35 | 40 | 35 |
| Ultra-high molecular weight polyethylene | 5 | 10 | 15 | 10 |
| Ethylene-octene copolymer | 4 | 6 | 8 | 6 |
| Maleic anhydride grafted polyethylene | 3 | 6 | 9 | 6 |
| Nano zine oxide/graphene complex | 3 | 4 | 6 | --- |
| Modified manometer silicon dioxide | 2 | 3 | 5 | --- |
| Magnesium stearate | 1 | 1.5 | 2 | 1.5 |
| Antioxidant DTBHQ | 0.3 | 0.5 | 0.7 | 0.5 |
PE films prepared by each embodiment and comparative example are tested for the property, the results detailed in Table 2.Wherein, using GB/T
1040-1992 tests the mechanical property of product；The impact breakage quality of product is carried out using GB/T 9639-1988
Test.The water vapo r transmission amount of product is tested using GB/T 1037-1988；Using QB/T 2591-2003 to product
Antibiotic rate is tested.
The performance of PE films prepared by 2 each embodiment and comparative example of table
As shown in Table 2, relative to the comparison for being not added with modified manometer silicon dioxide and nano zine oxide/graphene complex
Example 1 has higher tensile strength and unit impact breakage quality, this is because nanometer by the PE films prepared by embodiment 1-3
Silica and graphene have significant humidification.Meanwhile in graphene and nano zine oxide and nano silicon dioxide
Under collective effect, the gas barrier property and antibiotic property of PE films are significantly improved, this is because nano zine oxide and antibacterial
The synergistic effect of the inorganic-organic antiseptic of agent (organosilicon quaternary ammonium salt), significantly plays antibacterial action.And the two dimension of graphene
Lamellar structure has huge specific surface area, can significantly effective three-dimensional barrier, barrier gas material internal transmission with
Diffusion promotes barrier property.Compared to comparative example, the water vapo r transmission amount of embodiment 1-3 reduces 35%, 43% and 50% respectively,
Antibiotic rate is up to 99.6%, improves 20%.
