Description

A kind of flame retardant type antibacterial food packaging material and preparation method thereof
Technical field
The present invention relates to Food Packaging technology field, particularly relate to a kind of flame retardant type antibacterial food packaging material and making 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 flame retardant type antibacterial food packaging material and Its manufacture method.
The present invention is achieved by the following technical solutions:
A kind of flame retardant type antibacterial food packaging material, are prepared by the raw materials in: Low Density Polyethylene 100, nano oxygen Change zinc 2.5-2.9, truestar anisetree essential oil 5.4-6.2, sepiolite powder 2-3, activated carbon 4-6, zinc stearate 0.6-0.8, silane coupled Agent KH-570 5.7-6.1, vaseline 6-8, red phosphorus 1.2-1.5, needle-leaved wood fibre 10-12, suitable quantity of water.
The manufacture method of described a kind of flame retardant type antibacterial food packaging material, comprises the following steps:
(1) nano zine oxide, truestar anisetree essential oil stirring and evenly mixing are put in mixer, with the rotating speed high-speed stirring of 10000r/min Mix 30 seconds to obtain modified nano zinc oxide；
(2) vaseline being heated to molten condition, addition activated carbon, red phosphorus isolation air ultrasound disperse 30-40 minute modified Red phosphorus；
(3) sepiolite powder is ground uniform 120-140 mesh sieve, activation processing 20-30 minute at 565-580 DEG C excessively, be cooled to Room temperature adds needle-leaved wood fibre, Silane coupling reagent KH-570 ultrasonic disperse obtains modified meerschaum powder in 40-50 minute；
(4) by step (1), (3) reaction mass stirring and evenly mixing, ultrasonic grinding 10-15 minute, add Low Density Polyethylene, step (2) reactant and the mixing of other residual componentss, put into melt blending, pelletize in double screw extruder, obtain packaging pellet；
(5) the packaging pellet blowing obtained in step (4) 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 truestar anisetree essential oil, even if still having stronger antibiotic property under conditions of unglazed, broad-spectrum antibacterial property is high；Add simultaneously Modified sepiolite powder, as filler, is resistant to high temperature adsorption strong, by deoxygenation, dehumidifies, changes package except modes such as ethylene The pack environment of material internal, prevents the growth of microorganism, degradable low cost, and antibacterial effect is notable, utilizes the present invention to prepare Antibacterial food packaging material heat-resistant fireproof strong.
