Description

A kind of wear-resistant antibacterial packaging material for food and preparation method thereof
Technical field
The present invention relates to Food Packaging technology field, particularly relate to a kind of wear-resistant antibacterial packaging material for food and making side thereof Method.
Background technology
Microorganism volume is small, of a great variety, breeding rapidly and adapts to the ability of environment by force, the widest in distributed in nature General.Major part food nutritious, moisture is high, it is easy to caused putrid and deteriorated by the pollution of microorganism, significantly Shorten the shelf-life of food.The microorganism how preventing food is polluted, and the shelf-life of prolongation food is always the whole world and is correlated with Scientist's research and the problem paid close attention to.Along with the development of science and technology, utilize packaging material for food prepared by antimicrobial technology The most more can become a kind of practical and reliable antibacterial scheme.
In the last few years, along with going deep into and the expansion of Application of micron of nanotechnology research, application nano material realized Antibacterial functions has become current current research focus." nano-ZnO/LDPE antibacterial food packaging material are developed " literary composition is with low close The strong antibacterial action Nano-class zinc oxide that has of activation processing, as the base material of packaging for foodstuff, is passed through melting blending by degree polyethylene Method is added in base material, then through single screw extrusion machine and inflation film manufacturing machine, the pellet of gained is blow molded into thin film, i.e. prepares and provides Having the packaging material of antibacterial functions, result of the test shows: the packaging material prepared can not only extend the shelf-life of food, improves The safety of food, and the antibacterial that can be effectively prevented between person to person, people and thing, people and food, thing and food is intersected Infect, give the new implication of packaging for foodstuff and function.
But nano zine oxide Antibacterial Mechanism is photocatalysis antibacterial in literary composition, under there is no light catalysis, effect of food preservation Difference, shelf life is short, and condition is harsh and broad-spectrum antibacterial property is narrow, needs a kind of nontoxic, durable antibacterial effect of interpolation badly and urges without light The antibacterial compatibility therewith changed；Only have obstruct and defencive function with packaging material for food in eight-legged essay, structure is single, along with food The importance of packaging material safety constantly rises, and the requirement of packaging material for food is continuously increased by market, it is desirable to can be fresh Extend the shelf life with the food of high-quality, especially the demand to Active Packaging Materials because it can pass through deoxygenation, antibacterial, Dehumidifying, the pack environment of material internal of changing package except modes such as ethylene, release ethanol, prevent the growth of microorganism, Jin Erti The shelf-life of high food, thus be necessary prior art is modified.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of wear-resistant antibacterial packaging material for food and Manufacture method.
The present invention is achieved by the following technical solutions:
A kind of wear-resistant antibacterial packaging material for food, is prepared by the raw materials in: Low Density Polyethylene 100, nano oxidized Zinc 2.2-2.6, Fructus Foeniculi quintessence oil 5.3-6.1, benzoyl oxide 1-2, high wear-resistant carbon black 2-3, Oryza glutinosa glue 3-5, sodium humate 1.7- 2.1, aramid fiber 7-9, γ-chloropropyl triethoxysilane 5.8-6.2, sodium bicarbonate 0.2-0.4, suitable quantity of water.
The manufacture method of described a kind of wear-resistant antibacterial packaging material for food, comprises the following steps:
(1) sodium bicarbonate adds suitable quantity of water stirring dissolve to whole, be warming up to 80-90 DEG C, keep constant temperature to add nano oxidized Zinc, high-speed stirred back flow reaction 1-2 hour, filtering and washing is to neutrality and dries, and adds Fructus Foeniculi quintessence oil and puts in mixer, Within 30 seconds, modified nano zinc oxide is obtained with the rotating speed high-speed stirred of 10000r/min；
(2) high wear-resistant carbon black is ground uniform 120-140 mesh sieve of crossing, activation processing 20-30 minute at 530-570 DEG C, cooling Modified high abrasion is obtained to room temperature addition aramid fiber, Oryza glutinosa glue, γ-chloropropyl triethoxysilane ultrasonic disperse 40-50 minute White carbon black；
(3) by step (1), (2) reaction mass stirring and evenly mixing, add benzoyl oxide ultrasonic grinding 10-15 minute, add low-density Polyethylene and the mixing of other residual componentss, put into melt blending, pelletize in double screw extruder, obtain packaging pellet；
(4) the packaging pellet blowing obtained in step (3) is made the thin film of thickness about 70-90 μm, discharging.
The invention have the advantage that the present invention with Low Density Polyethylene as base material, by receiving after silane coupler activation processing Rice zinc oxide, as photocatalysis antibacterial agent, makes the organic principle such as antibacterial, moisture be decomposed, thus kills or bacteria growing inhibiting, And compound Fructus Foeniculi quintessence oil, even if still having stronger antibiotic property under conditions of unglazed, broad-spectrum antibacterial property is high；Add simultaneously Modified high wear-resistant carbon black is as filler, and adsorptivity is strong, by deoxygenation, dehumidifies, changes package in material except modes such as ethylene The pack environment in portion, prevents the growth of microorganism, degradable low cost, and antibacterial effect is notable, and utilize that the present invention prepares is antibacterial Packaging material for food is long for wear-resisting service life, make food at not adding preservative agent, without having longer shelf in the case of cold preservation Life-span.
